Dissertação de Mestrado Integrado em Medicina VeterináriaÉ sabido que o colostro é uma importante fonte de nutrição e imunidade para os vitelos recém-nascidos uma vez que estes, quando nascem, não são providos de imunoglobulinas, devido à estrutura epitéliocorial da placenta nos bovinos, sendo a imunidade adquirida através da ingestão de colostro. A falha na transferência desta imunidade passiva aumenta o risco de morbilidade e mortalidade dos vitelos, predispondo-os ao desenvolvimento de doença. O objetivo desta dissertação foi avaliar o impacto da qualidade do colostro na morbilidade, mortalidade e crescimento das vitelas recém-nascidas e perceber de que forma é que a qualidade e o maneio do colostro influenciam o sucesso da transferência de imunidade passiva. Foram analisados registos de 77 amostras de colostro proveniente do banco de colostro da exploração estudada e de 77 amostras de sangue de vitelas recém-nascidas, colhidas às 72h após a ingestão do colostro, para averiguar a ocorrência de falha de transferência de imunidade passiva. Foram também analisados o tempo de ingestão pós-parto e o leite de substituição dado aos recém-nascidos. O refratómetro ótico de Brix foi utilizado para a avaliação da qualidade do colostro, do soro sanguíneo e do leite de substituição, considerando-se como bons valores iguais ou superiores a 23%, 8,5% e 13%, respetivamente. No que diz respeito ao crescimento, foram efetuados registos de peso, altura ao garrote/cernelha e perímetro torácico ao nascimento, 2, 4 e 6 meses de idade. Relativamente à morbilidade, os tratamentos efetuados cingiram-se maioritariamente a episódios de diarreia e pneumonia sendo considerado febre acima de 39,3º. Foram também cruzados dados entre o colostro de vacas vacinadas e a probabilidade de sobrevivência dos vitelos. Durante o estudo faleceram 11 animais. A qualidade do colostro revelou-se boa em 88% das amostras, mas apenas 51% das vitelas obtiveram uma transferência de sucesso. O leite de substituição apresentou uma percentagem adequada de Brix em apenas 25% das refeições e o crescimento dos animais foi abaixo do esperado em todas as fases de crescimento analisadas, apesar de aos 6 meses apresentarem um ganho médio diário de peso superior ao esperado. Animais submetidos a um maior número de tratamentos apresentaram menor peso, altura e perímetro torácico aos 6 meses. Vitelas alimentadas com colostros de vacas vacinadas apresentaram 2,71 mais probabilidade de sobreviverem. Mesmo proporcionando aos recém-nascidos um colostro com concentração adequada de imunoglobulinas, a aquisição de uma boa imunidade não é garantida pois depende de vários fatores.
ABSTRACT - Impact of colostrum management on morbidity, mortality and growth in dairy calves - It is known that colostrum is an important source of nutrition and immunity for the newborn calves since they are not provided with immunoglobulins at birth due to the epithelial structure of the placenta in bovines and to acquire that immunity ingestion of colostrum is necessary. Failure of passive immune transfer increases the risk of morbidity and mortality in newborn calves, predisposing them to the development of diseases. The aim of this dissertation was to evaluate the impact of colostrum quality on morbidity, mortality and growth of newborn calves and to understand how the quality and management of colostrum influenced the success of passive immune transfer. Records of 77 samples of colostrum from the colostrum bank of the studied farm and 77 blood samples from newborn calves, collected at 72h after ingestion of colostrum, were analysed to ascertain the occurrence of failure of passive immune transfer. Postpartum intake time and replacement milk were also analysed. Brix optical refractometer was used to assess the quality of colostrum, blood serum and total solids in replacement milk, considering as good values equal to or above 23%, 8.5% and 13%, respectively. Regarding growth, data on weight, height at withers and chest girth was recorded at birth 2, 4 and 6 months of age. For morbidity, the treatments performed were mostly limited to episodes of diarrhoea and pneumonia, considering fever above 39.3º. Data was crossed between colostrum from vaccinated cows and calf’s survival probability. During the study, 11 animals perished. Colostrum quality was considered good in 88% of the samples, but only 51% of the calves had a successful transfer of immunity. The replacement milk showed an adequate Brix percentage in only 25% of the meals and the growth of the animals was below the expected in all growth stages, although at 6 months they presented an average daily weight gain higher than expected. Animals submitted to a greater number of treatments had lower weight, height and chest girth at 6 months. Calves fed with colostrum from vaccinated cows were 2.71 times more likely to survive. Even providing newborns colostrum with an adequate concentration of immunoglobulins, the acquisition of an adequate immunity is not guaranteed as it does not depend on one factor only.

O maracujá (Passiflora edulis flavicarpa) tem um flavor especial e intenso, porém em conseqüência da sua elevada acidez somente quantidades limitadas do suco podem ser adicionadas aos produtos alimentícios. Por outro lado, problemas de saúde ou preocupações com a estética corporal, têm estimulado a pesquisa e o desenvolvimento de produtos com baixo teor de açúcar, dentre estes produtos estão os sucos de frutas, como o de maçã (Pyrus malus, L.). Os processos de separação por membranas (PSM) têm sido considerados como uma alternativa viável na redução de acidez e açúcar em suco de frutas. Além disto, representam uma tecnologia limpa que não utiliza conservante e não altera o sabor do produto. Neste trabalho, sucos de maçã e maracujá foram nanofiltrados utilizando-se membrana polimérica na configuração espiral. O objetivo principal foi de reduzir o teor de sólidos solúveis no suco de maçã e de acidez no suco de maracujá. Também foram avaliados os efeitos da temperatura, pressão e velocidade tangencial, durante a nanofiltração do suco de maçã e investigado o comportamento da acidez em relação às condições operacionais, na nanofiltração do suco de maracujá. Nas condições utilizadas neste trabalho, foi possível uma redução de 19% nos sólidos solúveis do suco de maçã, sem alteração significativa de sua acidez. Verificou-se que, durante a nanofiltração, o fluxo permeado do suco de maçã foi diretamente proporcional ao aumento da pressão. Os resultados também mostraram uma proporcionalidade direta entre a temperatura e o fluxo permeado. Um aumento da temperatura de nanofiltração a partir de 36ºC resultou no aumento dos valores de brix, conseqüentemente, um aumento na permeação dos açúcares presentes no suco de maçã. Quanto ao suco de maracujá, houve uma redução de até 25% na acidez total. O fluxo de permeado, durante a nanofiltração do suco também foi diretamente proporcional ao aumento da pressão. Variações de pressão de 2 a 8 bar e de temperatura de 20 a 50ºC não provocaram diferenças nos valores de pH no permeado. Verificou-se uma redução da acidez titulável em função do aumento da pressão transmembrana durante a nanofiltração, enquanto ocorreu um aumento da acidez titulável do permeado com o aumento da temperatura. Teste de histerese mostrou que a membrana de nanofiltração utilizada sofreu compactação durante o aumento da pressão. Por outro, o coeficiente de colmatagem (CC) foi maior para maiores pressões em razão de uma maior permeação e, conseqüentemente, deve ser controlada através da velocidade tangencial e membranas com pontos de corte apropriados. Isto porque pressões mais elevadas são necessárias para a obtenção de fluxos permeados compatíveis com a realidade industrial. Finalmente pode-se concluir que a nanofiltração foi eficaz na redução de sólidos solúveis no suco de maçã e de acidez no suco de maracujá.
Passion fruit (Passiflora edulis flavicarpa) has a particular and intense flavor; however, due to its high acidity only limited amounts of juice can be added to food products. On the other hand, problems related to health or body esthetics concerns have stimulated research and the development of products with low sugar content, which include fruit juices, such as apple juice (Pyrus malus, L.). Membrane separation processes (MSP) have been considered as a viable alternative in the reduction of acidity and sugar in fruit juice. Furthermore, this is a clean technology which does not require preservatives and does not alter the taste of the product. In this study, apple and passion fruit juices were nanofiltered using a polymeric membrane in a spiral configuration. The main objective was to reduce the soluble solids content of the apple juice and the acidity of the passion fruit juice. The effects of temperature, pressure and tangential velocity were also evaluated during the nanofiltration of the apple juice and the behavior of the acidity was investigated in relation to the operating conditions in the nanofiltration of the passion fruit juice. Under the conditions used in this study, it was possible to achieve a 19% reduction in the soluble solids of the apple juice, without altering significantly its acidity. It was verified that during the nanofiltration the permeate flux of the apple juice was directly proportional to the increase in pressure. The results also showed a direct proportionality between temperature and permeate flux. An increase in the nanofiltration temperature from 36ºC resulted in an increase in the brix values and consequently, an increase in the permeation of sugars present in the apple juice. Regarding the passion fruit juice, there was a reduction of up to 5% in the total acidity. The permeate flux during the nanofiltration of this juice was also directly proportional to the pressure increase. Variations in the pressure from 2 to 8 bar and in the temperature from 20 to 50ºC did not result in changes in the pH values of the permeate. A reduction in the titratable acidity was verified as a function of the increase in the transmembrane pressure during the nanofiltration, whereas there was an increase in the titratable acidity of the permeate with the increase in temperature. The hysteresis test showed that the nanofiltration membrane underwent compaction during the pressure increase. However, the clogging coefficient (CC) increased at higher pressures due to a greater permeation and, thus, it must be controlled through the tangential velocity and membranes with appropriate cut-off points. This is because higher pressures are required for the obtainment of permeate fluxes compatible with the industrial reality. Finally, it can be concluded that the nanofiltration was efficient in the reduction of soluble solids in apply juice and acidity in passion fruit juice.

Fundação de Amparo a Pesquisa no Estado do Rio Grande do SulThe Brazilian ethanol production is mainly based on the sugarcane crop, however in the off-season mills plants cease processing, decreasing revenues as a result of the shortage of raw materials. It is in this scenario that fits the sweet sorghum, being able to provide quality material during the off-season sugarcane, in the summer months. The objective of this study was to evaluate the qualitative parameters and maturation curves of eleven genotypes of sweet sorghum, aiming ethanol production. Field experiment was conducted in Santa Maria-RS, in two growing seasons (2012/13 and 2013/14). The experimental design was randomized blocks with three replications and the treatments consisted of eleven genotypes, seven varieties (BRS506, BRS511, Fepagro 17, Fepagro 19, Past 81-04, Past 29-51 and Past 29-49) and four hybrids (CV007, CV147, CV568 and CV198). The quality of sweet sorghum juice was evaluated based on parameters: sucrose content (%), reducing sugars (%), purity (%), total soluble solids (°Brix), total recoverable sugar (kg t-1), fiber (%) and ethanol production (l ha-1). It was determined the maturity curve to characterize the industrial use period (IUP). The genotypes BRS506, BRS511 and CV198 showed IUP over 30 days. The BRS506 and BRS511 genotypes showed better characteristics for ethanol production.
A produção brasileira de etanol é baseada principalmente na cultura da cana-de-açúcar, porém, no período de entressafra as usinas cessam o processamento, diminuindo as receitas em decorrência da escassez de matéria-prima. É neste cenário que se encaixa o sorgo sacarino, capaz de fornecer material de qualidade durante o período de entressafra da cana, nos meses de verão. Desta forma, o objetivo do presente estudo foi avaliar os parâmetros qualitativos e as curvas de maturação de onze genótipos de sorgo sacarino durante dois anos de cultivo, visando a produção de etanol. O experimento foi conduzido em Santa Maria-RS, nos anos agrícolas de 2012/13 e 2013/14. Foi utilizado o delineamento experimental de blocos ao acaso com três repetições e os tratamentos foram compostos por onze materiais genéticos, sendo sete variedades (BRS506, BRS511, Fepagro 17, Fepagro 19, Past 81-04, Past 29-51 e Past 29-49) e quatro híbridos (CV007, CV147, CV568 e CV198). Foram avaliados os parâmetros qualitativos sacarose do caldo (%), açúcares redutores do caldo (%), pureza do caldo (%), sólidos solúveis totais (°Brix), açúcar total recuperável (kg t-1), fibra (%), rendimento de etanol (l ha-1) e também as curvas de maturação para a obtenção do período de utilização industrial (PUI). Os genótipos BRS506, BRS511 e CV198 apresentaram PUI superior a 30 dias. Os genótipos BRS506 e BRS511 apresentaram melhores características para produção de etanol.

Mestrado em Engenharia Agronómica - Instituto Superior de AgronomiaThis study sought to assess the influence of cultivar and site quality of “Pele de Sapo” melon types. The cultivars studied where “MP 3177”, “Hidalgo”, “Rabal” and “Ruidera”. For this purpose were conducted three trials in Santarem, in Évora and in Amareleja. After the harvest, the melons were to three types of procedures, to determine the quality of the fruit of the twelve combinations Location x Cultivar, in first place the measurement of soluble solids content and titratable acidity, in second sensory tests, and at last the correlations performed between the first two. One of the conclusions is that the melons with a soluble solids content higher than 13º Brix are well accepted by consumers, it also concluded that to determine the exact date of harvest should be carried out sampling and it is recommended to Harvesting when the SSC is above 13ºBrix. Analysing the data, another conclusion obtained, is that the fruits” ripeness is central to their organoleptic characteristics and their acceptance by the consumer. We can also say that the “Rabal” cultivar is excluded, either by poor performance on consumer due to the weak resistance to fungus, on the other hand the cultivar "Ruidera" proved susceptible to mildew attack leading to low production and fruits of lesser quality. The “Hidalgo” and “MP3177” were the most resistant to powdery mildew. In other varieties it was necessary to harvest only plants not attacked for not affect the quality of melon. It is recommended that the cultivar "Hidalgo" can begin to be planted in early May to begin to be harvested in mid-July, while the "MP3177" can be planted until mid-July, ensuring crops until October

Previous issue date: 2011-02-18The objective of the present work was to study the pineapple production in the southern coastal region of Espírito Santo State, in Marataízes and Itapemirim. The specifics objectives were: developed a mathematical model to estimate the fruit weight of pineapple cultivar Jupi‟ and evaluate yield and quality of pineapple Jupi‟ produced in the region. To evaluate yield and fruit quality were realized in field and laboratory evaluations. In field were evaluated: plant arrangement, fruit number by plot, plant number with incidence of symptoms of mealybugs, fusariosis and bud moth, and total fruits number. In laboratory were evaluated: weight with and without crown; crown weight; length; base, median and apical diameter; number of individual fruits on spiral; juice percentage; total soluble solids (TSS), titratable acidity (TA) and ratio TSS/TA. Descriptive statistics were realized: media, standard deviation and coefficient of variation and box plot graphs. The results showed that fruit length (C) and median diameter (DM) are appropriate to estimate the weight of fruit without crown (MF), and the mathematical model more adequate are MFe=(β0+β1C+β2DM)x1,06. It was concluded that for conditions of southern coastal region of Espírito Santo: yield in the region is lower than Brazilian yield. The physical characteristics, in large percentage, are lower than the values of ideal values at the market; for the characteristics TSS and TA are close required by the consumer; and ratio TSS/TA is close to that described in the literature
Objetivou-se com este trabalho estudar a produção do abacaxi na região litorânea Sul do Estado do Espírito Santo, nos municípios de Marataízes e Itapemirim. Os objetivos específicos foram: definir um modelo matemático estimador de massa do abacaxi Jupi‟ e avaliar a produtividade e a qualidade dos frutos do abacaxizeiro Jupi‟ produzido na região. Para avaliar a produtividade e a qualidade foram realizadas avaliações em campo e laboratório. Em campo foram avaliados: espaçamento; número de frutos por parcela; número de plantas com incidência de sintomatologia de cochonilha, fusariose e broca-dos-frutos; e número total de frutos. Em laboratório avaliou-se: peso do abacaxi com e sem coroa; peso da coroa; comprimento do abacaxi; diâmetro na região basal, média e do ápice; número de frutilhos na espiral; porcentagem de suco; sólidos solúveis totais (SST); acidez titulável total (ATT); e relação SST/ATT. Foram realizadas análises estatísticas descritivas dos dados: média, desvio-padrão e coeficiente de variação e desenvolvidos gráficos Box plot. Os resultados mostraram que o comprimento (C) e o diâmetro médio (DM) do fruto são adequados para estimar a massa do fruto sem coroa (MF), sendo o modelo matemático mais adequado MFe=(β0+β1C+β2DM)x1,06. Concluiu-se que para as condições da região litorânea Sul capixaba: a produtividade na região é inferior à média brasileira; as características físicas de qualidade do abacaxi, em grande percentual dos frutos, estão abaixo dos valores ideais praticados no mercado; quanto às características SST e ATT, os valores estão próximos aos requeridos pelo consumidor; e a relação SST/ATT está próxima da descrita na literatura

Mestrado em Viticultura e Enologia - Instituto Superior de Agronomia / Faculdade de Ciências. Universidade do PortoIn this work, WinePen validation procedures were applied in order to verify the robustness of the device in the field and the models used to estimate the parameters Brix, Titratable acidity and Anthocyanins. This device’s operating system is based on reflectance and fluorescence. This validation was held in 2013, on vineyards with white and red varieties, in the Superior Institute of Agronomy, situated in the Wine Region of Lisbon. For WinePen validations, 25 berries of each variety were measured, under different conditions (laboratory and field) in order to verify the light effect on measurements. The berries were first analyzed by WinePen and afterwards examined in the laboratory. In order to select the best models, the fitting quality of the observed values was evaluated using the following deviance measures: determination coefficient (R2), mean absolute error (MAE); root mean square error (RMSE). High and significant correlations for Brix (0.93 to 0.96) and for titratable acidity (0.86 to 0.96) were observed for different types of environment (laboratory and field) and for different varieties (whites and reds). However, the anthocyanins parameter observed lower and less significant correlations (0.70) in both reading conditions. Thereby, the results obtained demonstrate the reliability of measurements performed by WinePen for different varieties and environments

As plantas de mirtilo crescem usualmente em climas mais frios que o
mediterrâneo, pois necessitam de acumular um elevado número de horas de
temperaturas abaixo de 7,2 ºC (“chilling”) para que se dê a quebra de dormência.
Contudo, o aparecimento de cultivares denominadas “Southern Highbush” com
menores necessidades de acumulação de baixas temperaturas do que as
tradicionais (“Northern Highbush”) levou a que na Califórnia a produção destes
frutos esteja a ser implantada com sucesso. Em Portugal, temos já também uma
área considerável de produção no litoral Alentejano e em Sever do Vouga. Tendo
em consideração os preços dos frutos de mirtilo e a reconhecida influência do
consumo destes na saúde, este trabalho teve como objectivo estudar o
comportamento agronómico e produtivo de 6 cultivares de mirtilo (“Star”,
“Misty”, “Southmoon”, “Ozarkblue”, “O’Neal” e “Nui”) (Vaccinium corymbosum
L.) no Alentejo interior. Para o efeito realizou-se um ensaio em blocos
casualizados com 4 repetições. No 2º ano, após a plantação, foram efectuadas
diferentes medições ao longo do ciclo de cultura para analisar a evolução do pH
do solo, o desenvolvimento das plantas e a qualidade dos frutos. O pH do solo, no
2º ano, apresentou valores compreendidos entre 4,61 e 5,16, ou seja, dentro do
intervalo considerado adequado para o crescimento das plantas de mirtilo. Os
resultados preliminares deste estudo mostraram-nos que as cultivares cresceram
significativamente e que houve diferenciação floral. A floração nas cultivares
Star, Misty e Southmoon foi a mais precoce, tendo início em meados de Janeiro, o
que pode ser prejudicial devido à elevada probabilidade de ocorrência de geadas.
No que diz respeito à qualidade dos frutos, o “ºbrix” variou entre 12,1 e 14,6 e o
pH entre 2,72 e 3,37, estando dentro do intervalo aconselhado para os frutos de
mirtilo; ABSTRACT: The blueberry plants usually grow in climates colder than the Mediterranean,
because they need specific chilling requirements. They need to accumulate a
certain number of hours of temperatures below 7,2 degrees Celsius, in order to
break dormancy.
However, a genetic new cultivars called "Southern Highbush" have reduce needed
for accumulation of low temperatures than the traditional ("Northern Highbush"),
led California to a successfully production of these fruits.
In Portugal, we also have a significant area of production in the Alentejo coast and
Sever do Vouga. Having in consideration the blueberry prices and the beneficts on
human health, the purpose of this study was to learn about the agronomic behavior
and production of 6 varieties of blueberry (“Star”, “Misty”, “Southmoon”,
“Ozarkblue”, “O’Neal” e “Nui”) (Vaccinium corymbosum L.) suited in a climate
as Alentejo. To this end we carried out an experiment in randomized blocks with 4
replications. In the second year after planting, different measurements were made
during the growing season to analyze the evolution of soil pH, plant growth and
fruit quality. Soil pH ranged between 4,61 and 5,16, within the range considered
adequate for the growth of blueberry plants. Preliminary results of this study
showed us that the cultivars grown significantly and there were floral
differentiation. Thus, the flowering in the cultivar Star, Misty and Southmoon
were the earliest, beginning in mid-January, which may be harmful due to the high
probability of frost. About the fruit quality, "ºbrix" varied between 12,1 and 14,6
and the pH between 2,72 and 3,37, is within the range desirable for the blueberry
fruit.

A maturação da cana-de-açúcar do ponto de vista econômico é determinada pelas análises tecnológicas realizadas a partir do caldo extraído dos colmos e os teores obtidos são comparados aos dados de literatura. Diversas variáveis podem auxiliar para estimar a maturação, no entanto, as atualmente usuais são consideradas empíricas, pouco exatas ou trabalhosas. Nota-se que o processo de maturação da cana-de-açúcar influencia na sua morfologia, fisiologia e metabolismo e a detecção ideal seria realizada pela observação de todos estes fatores, além de que, se acompanhados, poderiam auxiliar na distinção prévia do potencial produtivo de novos genótipos, sem necessariamente cultivá-los até o final do ciclo biológico. O objetivo do trabalho foi detectar a maturação da cana-de-açúcar por meio das alterações morfológicas, fisiológicas, enzimáticas e nutricionais em duas variedades de cana-de-açúcar. O experimento foi realizado na Usina da Barra - Grupo Raízen, as avaliações entre março e julho de 2015 e as variedades utilizadas foram a RB855156 (precoce) e a RB92579 (tardia). Avaliou-se a altura de plantas, diâmetro e número de colmos, comprimento e número de entrenós, número de folhas verdes, comprimento e largura da folha +3, área foliar e índice de área foliar, massa da matéria fresca e seca das folhas e colmos, índice SPAD, conteúdo de clorofilas e carotenoides, NDVI, Brix% caldo, pureza, Pol% cana, ATR, ART, teor de fibras, AR, U% e PBU, atividade da SPS, SuSy e das invertases ácidas e neutras do colmo e das folhas e o teor foliar de N, P, K, Ca, Mg, Fe, S e B. Para acompanhar e discriminar o período de maturação entre as duas variedades, os dados das análises tecnológicas foram submetidos ao teste de "t" (teste de Student, p < 0,05) entre as variedades e dentro das épocas de estudos. Para determinar quais variáveis estavam associadas à maturação das variedades, realizou-se a correlação de Pearson entre as variáveis morfológicas, fisiológicas, enzimáticas, nutricionais e as variáveis tecnológicas, para cada variedade. A maturação da variedade RB855156 foi detectada através das variáveis morfológicas largura da folha +3, área foliar, índice de área foliar, número de entrenós, as fisiológicas índice SPAD, teor de clorofila a, b, a+b, carotenóides e a atividade enzimática da SuSy no sentido quebra. A variedade RB92579 até a última avaliação, conforme o Brix e pureza do caldo, não havia iniciado o processo de maturação. No entanto, ao compararmos as variáveis fisiológicas, morfológicas e enzimáticas com os atributos tecnológicos, nota-se que as variáveis que foram selecionadas pela análise de correlação foram as mesmas da variedade RB855156, com exceção do índice SPAD e largura da folha +3.As variáveis número de entrenós, diâmetro do colmo, altura de inserção da folha +1, comprimento da folha +3, índice SPAD e número de folhas verdes podem serutilizadas para estimar, por meio de regressões múltiplas, as características tecnológicas Brix% caldo, pureza, umidade, ART, PCC e ATR durante a maturação das variedades estudadas.
The ripeness of sugarcane from the economic point of view is determined by the technological analyzes carried out from the broth extracted from the stalks and the obtained contents are compared to the literature data. Several variables may help to estimate ripeness, however, the current ones are considered empirical, not exact or laborious. The sugar cane ripeness process influences its morphology, physiology and metabolism and the ideal detection would be performed by observing all these factors, and if accompanied, could help in the previous distinction of productive potential of new genotypes, without necessarily growing them until the end of the biological cycle. The objective of this work was to detect the ripeness of sugarcane by means of morphological, physiological, enzymatic and nutritional changes in two sugarcane varieties. The experiment was carried out at the Barra Plant - Raízen Group, evaluations between March and July 2015 and the varieties used were RB855156 (early) and RB92579 (late). The height of plants, length, diameter and number of stalks, length and number of internodes, number of green leaves, length and width of leaf +3, leaf area and leaf area index, fresh and dry matter mass of leaves and stems, SPAD index, chlorophyll and carotenoid content, NDVI, Brix% broth, purity, Pol%, ATR, ART, fiber content, AR, U% and PBU, SPS activity, SuSy and acid and leaf, and leaf contents of N, P, K, Ca, Mg, Fe, S and B. To monitor and discriminate the ripeness period between the two varieties, the data of the technological analyzes were submitted to the test of "T" (Student test, p <0.05) between the varieties and within the study periods. In order to determine which variables were associated with the maturation of the varieties, the Pearson correlation was performed between the morphological, physiological, enzymatic, nutritional variables and the technological variables, for each variety. The maturation of the variety RB855156 was detected through the morphological variables leaf width +3, leaf area, leaf area index, number of internodes, physiological index SPAD, chlorophyll a, b, a + b content, carotenoids and enzymatic activity of SuSy in the sense breaks. The variety RB92579 until the last evaluation, according to the Brix and purity of the broth, had not started the maturation process. However, when comparing the physiological, morphological and enzymatic variables with the technological attributes, it is noticed that the variables that were selected by the correlation analysis were the same of the variety RB855156, except for the SPAD index and leaf width + 3. As The number of internodes, stalk diameter, leaf insertion height +1, leaf length +3, SPAD index and number of green leaves can be used to estimate, by means of multiple regressions, the technological characteristics Brix% broth, purity, Moisture, ART, PCC and ATR during maturation of the studied varieties.

Poucos são os estudos acerca da importância relativa dos parentais na performance das progênies para os atributos de interesse econômico em cana- de-açúcar. Os objetivos deste trabalho foram verificar a influência de efeito recíproco para caracteres de importância agronômica em cana-de-açúcar quanto ao número de colmos (lnNC), brix e tonelada de biomassa por hectare (TBIOH) e avaliar 8 famílias de cana-de-açúcar pelo método de modelos mistos, destacando as famílias e progênies superiores para os atributos analisados. Quatro cruzamentos biparentais e seus recíprocos, gerando 8 famílias de irmãos completos e a testemunha IACSP95-5000, foram avaliados em delineamento de blocos casualizados, com 20 blocos. As predições das famílias mostraram variabilidade para número de colmos (lnNC), brix e biomassa de touceira (BIO), o que permite seleção. Verificou-se a existência de efeitos maternos, paternos e interação entre eles para as características de brix e TBIOH. O parental feminino apresentou maior contribuição na determinação da performance do brix das progênies, porém, nem sempre o parental com alto teor de brix irá produzir progênie com performance superior.

Abstract: Sugarcane breeding has contributed to the sector, releasing varieties more productive, resistant or tolerant to major diseases and pests of the crop. The purpose of this study was to verify the influence of reciprocal effect to sugarcane agronomic traits: stalk number, brix and tonnes of biomass per hectare (TBIOH) and to evaluate eight sugarcane families by mixed model highlighting the superior families and progenies for the traits analyzed. Progenies from four biparental crosses and their reciprocal crosses were assessed in plant cane and first ratoon cane cycles. The experiment design used was completely randomized blocks, with 20 replications and 9 treatments (8 sugarcane families and a cultivated variety IACSP95-5000). Maternal, paternal and maternal x paternal interaction for the traits brix and TBIOH were observed. Significant reciprocal differences (P≤0.05) were found for stalk number brix and TBIOH in both cane cycles. Half of the assessed reciprocal crosses showed favorable effects within the reciprocals (P≤0,10) with a brix increase in the progeny means ranging from 0.9 to 1.7, using female parent IACSP98-2053. TBIOH showed significant effect within every reciprocal cross assessed in plant cane cycle. The predictions showed variability for stalk number, brix and biomass. The female parent IACSP01-2419 and the male parent IACSP95- 5000 can be indicated as female parents to obtain individual progeny with higher brix content and TBIOH productivity.

As condições do ambiente de cultivo e o genótipo podem influenciar a produtividade e a composição dos frutos do tomateiro. Para quantificar tais efeitos, foram conduzidos dois experimentos, no Setor de Olericultura do Departamento de Fitotecnia, na Universidade Federal de Viçosa, Viçosa - MG, no período de janeiro a maio de 2002. Um experimento foi conduzido em ambiente protegido, em estufa tipo capela, coberta com filme plástico de 0,1 mm e o outro no campo sob condições naturais, sem proteção. Utilizou- se o delineamento em blocos casualizados com 6 repetições e três genótipos sendo: 'Santa Clara', híbrido Carmen e um acesso do Banco de Germoplasma de Hortaliças da UFV, codificado como 'BGH-320'. Os frutos foram colhidos no estádio completamente maduro, com 100% da superfície apresentando coloração vermelha intensa. Foram avaliados: 1- características de produção: a) produção total e b) produção comercial. 2- características de qualidade do fruto: a) 'sabor', obtido pela relação sólidos solúveis totais/acidez titulável; b) teor de açúcares redutores; c) acidez titulável (expressa em % de ácido cítrico); d) pH, e) teor de sólidos solúveis totais (expresso em oBrix); f) 'licopeno': g) ácido ascórbico e h) teor de potássio nos frutos. Foi realizada a análise conjunta dos dados de ambos os experimentos. A produtividade dos três genótipos foi superior no ambiente protegido. O híbrido Carmen produziu 105,46 t.ha-1, valor este superior aos demais genótipos. A menor produtividade foi a do 'Santa Clara' (30,04 t.ha-1) quando cultivado no campo. Frutos produzidos no ambiente protegido foram menos saborosos, e com menores teores de açúcares redutores, oBrix, ácido ascórbico e acidez que os frutos produzidos no campo. Entre genótipos, frutos do 'Carmen' e do 'Santa Clara' foram mais saborosos e com maior teor de açúcares redutores e pH que frutos do 'BGH-320'. A acidez titulável e o teor de 'licopeno' dos frutos do 'BGH-320' foram superiores às dos frutos do 'Carmen'e do 'Santa Clara'. O maior teor de ácido ascórbico foi observado nos frutos de 'Santa Clara'. Observou-se, de maneira geral, que o aumento da produtividade das plantas afetou a qualidade dos frutos. Os dados do 'sabor' dos frutos do 'Carmen' ajustaram-se ao modelo quadrático de regressão bivariada com o aumento da produtividade das plantas cultivadas no ambiente protegido. O teor de açúcares redutores dos frutos do 'BGH-320' produzidos no ambiente protegido e a acidez dos frutos de 'Santa Clara' produzidos no campo foram reduzidos à medida que aumentou a produtividade das plantas. O oBrix dos frutos do 'Carmen' e o 'sabor' dos frutos de 'Santa Clara' aumentaram com o aumento da produtividade das plantas cultivadas no campo. Os dados referentes ao teor de potássio dos frutos do acesso 'BGH-320' ajustaram-se ao modelo quadrático de regressão bivariada com o aumento da produtividade das plantas cultivadas no ambiente protegido.
Growth environment and genotype can be influence tomato yield and fruit composition. To quantify these effects, two experiments were carried, in the Departamento de Fitotecnia, in the Universidade Federal de Viçosa, Viçosa - MG, from January to May of 2002. An experiment was carried in protected environment, in greenhouse type chapel, covered with plastic film of 0,1 mm and the other in the field under natural conditions, without protection. Was used experimental design in randomized blocks with 6 replication and three genotypes being: 'Santa Clara', Carmen hybrid and an access of the UFV Germplasm Vegetable Bank, codified as 'BGH-320'. The fruits were picked completely ripe, with 100% of the surface presenting intense red coloration. They were appraised: 1 - yield characteristics: a) total yield and b) marketable yield. 2 - fruit quality characteristics: a) "flavor", obtained by total solids soluble /titratable acidity ratio; b) sugar reducing content; c) titratable acidity (expressed in % citric acid); d) pH, e) total soluble solids content (expressed in oBrix); f) "lycopene"; g) ascorbic acid and h) fruit potassium content. The united analysis of the data of both experiments was accomplished. The Yield of the three genotypes was higher in the protected atmosphere. The Carmen hybrid yield was 105,46 t.ha-1, upper to the other genotypes. The small yield was the Santa Clara cultivar (30,04 t.ha-1) when growth in the field. Fruits produced in the protected environment makes less tasty, and with smaller sugar reducing content, oBrix, ascorbic acid and acidity that the fruits produced in the field. Among genotypes, fruits of the 'Carmen' and 'Santa Clara' they were tastier and with better sugar reducing content and pH that 'BGH-320" fruits. Titratable acidity and "lycopene" content of the 'BGH-320' fruit they were better than 'Carmen' and 'Santa Clara' fruits. The largest ascorbic acid content was observed in the 'Santa Clara' fruits. It was observed, in a general way, that the increase of the plant yield affected the fruit quality. 'Carmen' fruit "flavor" data they were adjusted to the quadratic component of bivariate relationship with the increase of the plant yield growth in the protected environment. Sugar reducing content of the 'BGH-320' fruits produced in the protected atmosphere and the acidity of the 'Santa Clara' fruits produced in the field decrease as it increased of the plant yield. oBrix of the 'Carmen' fruits and the 'Santa Clara' fruit "flavor" increased with the increase of the plant yield growth in the field. Potassium content of the 'BGH-320' fruits were adjusted to the quadratic component of bivariate relationship with the increase of the plant yield growth in the protected environment.

Full textAbstract:
Doutoramento em BiomedicinaA BRI2 e a BRI3 são proteínas transmembranares de tipo II cujas funções fisiológicas ainda não se encontram bem caracterizadas. Duas mutações autossómicas dominantes no gene BRI2 estão na origem de duas formas de demência rara: Demência Familiar Britânica e Demência Familiar Dinamarquesa. Estas partilham características clinicas e neuropatológicas com a doença de Alzheimer, nomeadamente deposição de proteínas anormais no cérebro. Apesar de nunca ter sido associada a qualquer doença, a BRI3 está enriquecida no sistema nervoso central o que sugere que possa ter uma função neuronal. Interações proteína-proteína têm adquirido uma importância crescente no estudo de funções de proteínas e vias de sinalização subjacentes. Neste trabalho, foram identificadas novas interações entre a BRI2 e a proteína fosfatase 1 (PP1), bem como entre a BRI3 com a PP1. A PP1 é a uma importante fosfatase serina/treonina presente em organismos eucariotas, onde se estima que seja capaz de catalisar a maioria dos eventos de defosforilação. Adicionalmente, determinámos a BRI2 e BRI3 como substratos da PP1, e identificámos os motivos RVxF presentes nos seus N-terminais como responsáveis pela ligação à PP1. A relevância fisiológica do complexo BRI2:PP1 foi investigada, e demonstrámos pela primeira vez que a fosforilação da BRI2, nomeadamente a defosforilação pela PP1, é um mecanismo de regulação do seu processamento proteolítico. Estabelecemos ainda uma relação entre os níveis de fosforilação da BRI2 com a diferenciação de processos neuronais, onde a fosforilação da proteína total parece estar envolvida no surgimento de processos neuronais, enquanto o fragmento Nterminal resultante do seu processamento parece estar relacionado com o elongamento e estabilização dos processos neuronais. No decorrer do trabalho, identificámos e caracterizámos os interactomas das proteínas BRI2 e BRI3 em cérebro, recorrendo a co-imunoprecipitações e identificação das proteínas por espectrometria de massa. Análise in silico do interactome da BRI2 reforçou os nossos resultados sugerindo um papel para esta proteína na diferenciação neuronal, e vários mecanismos subjacentes foram evidenciados. Adicionalmente, a análise dos interactomas localiza ambas proteínas na sinapse (pré e pós-sinapse). Esta evidência juntamente com a descoberta de interações com proteínas estruturais destes compartimentos celulares, nomeadamente a PSD-95, sugere um papel importante para ambas as proteínas em sinalização e transmissão sináptica. Assim, os nossos resultados compreendem informação importante para estudos futuros acerca da biologia das proteínas BRI2 e BRI3, e mecanismos celulares envolvidos, bem como na sua associação com o desenvolvimento de neuropatologias.
BRI2 and BRI3 are type II transmembrane protein family members whose physiological functions are poorly understood. Two different autosomal dominant mutations in the BRI2 gene are responsible for the development of two rare early-onset forms of dementia: Familial British and Familial Danish dementias that share clinical and neuropathological characteristics with Alzheimer´s disease, involving abnormal proteins’ deposition in the brain. For BRI3 no disease association has been established so far, nevertheless, its enriched expression in the central nervous system strongly suggests a role for BRI3 in neuronal function. Protein-protein interactions are becoming increasingly important in the study of protein function and underlying signaling pathways. In this work, both BRI2 and BRI3 were identified as novel protein phosphatase 1 (PP1) interacting proteins. PP1 is the major Ser/Thr protein phosphatase present in eukaryotic organisms, which catalyses the majority of protein dephosphorylation events. Moreover, we were able to determine BRI2 and BRI3 as PP1 substrates, which bind to the latter through an RVxF-like motif located in their N-terminal part. The physiological relevance of BRI2:PP1 complex was pursued, and we provide for the first time evidence suggesting that BRI2 phosphorylation, namely via PP1 dephosphorylation, is a regulatory mechanism for its proteolytic processing. Further, a correlation between BRI2 phosphorylation and neurite outgrowth was established. The phosphorylation of full-length protein seems to promote the emergence of neurites whereas the increased BRI2 N-terminal processing fragment plays a role in neurites’ elongation and stabilization. Herein, we also identified and characterized the interactome of both BRI2 and BRI3 in the brain using co-immunoprecipitation followed by mass spectrometry analysis. In silico analysis of the BRI2 interactome strengthened our results suggesting a role in neuronal differentiation and some underlying mechanisms were pointed out. Moreover, interactomes’ analysis suggested the presence of both BRI2 and BRI3 at synapses (pre- and post-synapse). This finding together with their ability to form complexes with structural constituents of these compartments, namely PSD-95 suggested an important role for both proteins in synaptic signaling and synaptic transmission. Thus, our results provide valuable information for further studies on BRI2 and BRI3 biology, and potential underlying molecular mechanisms, as well as associations with neuropathologies.

Sweet sorghum (Sorghum bicolor L. Moench) is an important bioenergy crop. There is a wide array of genetic diversity in sweet sorghum germplasm collections. However, information on traits associated with sugar yield, optimum harvesting time for maximum sugar yield, effects of abiotic stresses on sugar yield is scarce. The objectives of the present study were: to identify traits that are associated with sugar yield, to determine the optimum harvesting time for maximum sugar yield and to understand the physiological responses of different sweet sorghum genotypes to drought and high temperature. In order to meet these objectives, five independent field and greenhouse studies were conducted. Field experiments were conducted using 280 sweet sorghum germplasm and were evaluated for 2 years. From this study, 30 genotypes representing high and low sugar yielders were selected for the subsequent experiment. We observed a significant variation in physiological, morphological and sugar yield traits associated with biofuel production. In the selection experiment, investigations on the morphological, physiological attributes helped to identify those characters which influence or limit sugar yield in the sweet sorghum. Another field study was conducted to optimize the harvesting time for obtaining highest sugar and juice yields in sweet sorghum. Sweet sorghum variety M81E was harvested at ten growth stages. Our results suggest that the optimum time for harvesting of sweet sorghum cultivar M81E is between milk and hard dough stages when highest sugar yield was observed. Studies on different levels of water stress were studied under greenhouse conditions. Four sweet sorghum genotypes (Awanlek, Smith, Tracy and Wray) were subjected to three water stress treatments (100% pot capacity (PC); 70% PC and 30% PC) for 20 days at early seed filling (Milk) stage. The results showed that genotypes differed significantly for all growth and yield, biochemical and physiological traits. Severe water stress significantly decreased juice and sugar yields by decreasing net photosynthetic rate, transpiration rate, stomatal conductance and sucrose content in the stem juice. Genotypes Tracy and Wray produced significantly highest brix, stem fresh weight, juice and sugar yield under both irrigated and water stress conditions. In another greenhouse study, we quantified the effects of drought, high temperature, and their combinations on growth, physiology and yield of sweet sorghum genotypes. The same four genotypes above were subjected to four treatments, T1 - control, T2 - drought stress, T3 - high temperature stress and T4 - combination of drought and high temperature for 16 days after anthesis. The result showed that significant difference was observed for growth and yield traits, physiological traits and non-reducing and total sugar content in juice for genotypes and treatments. Among the genotypes Tracy recorded higher juice and sugar yield. Among the various treatments, combination of drought and high temperature was found to be more deleterious in reducing most of the biofuel traits followed by drought and high temperature stress. The above studies gave significant findings with regards to the identification of superior sweet sorghum germplasm, their tolerance capacity to different abiotic stresses, which allows better selection for the use of bioenergy production.

Full textAbstract:
A indução da maturação através de produtos químicos é uma prática usual nos sistemas de produção de cana-de-açúcar no Brasil, sendo que dentre os maturadores extensivamente utilizados destaca-se o etefon. No entanto, a interação de fatores ligados ao clima e fisiologia da cultura no momento da aplicação, com as características físico-químicas do etefon podem influenciar sua eficácia. Sendo o etefon um ácido fraco, o pH da calda de aplicação pode interferir no seu processo de absorção e ação indutora de maturação na cultura da cana-de-açúcar. Sendo assim, o objetivo da presente pesquisa foi de verificar a interação entre a redução do pH da calda de pulverização com doses de etefon na eficácia de indução da maturação pelo maturador em dois genótipos de cana-de-açúcar. Para isso foram utilizadas duas variedades de cana-de-açúcar SP86-0155 e SP84-143. Os tratamentos resultaram da combinação de quatro doses de etefon (337,68; 385,92; 434,16; 482,4 g ha-1) além da testemunha sem a aplicação do maturador e dois pHs de calda (3,5 e 6,8). Foi avaliada a qualidade tecnológica dos colmos de cana-de-açúcar, através dos atributos pol % na cana, Brix % caldo, % de açúcares redutores, teor de fibra, pureza para ambas as variedades e a produtividade de colmos industrializáveis e de açúcar por hectare para a variedade SP84-1451, aos 4, 23, 37, 51 e 69 dias após a aplicação dos tratamentos (DAA). Para a variedade SP84-1431 ocorreu tendência de que à medida que a dose de etefon aumenta maior é o incremento de Brix % caldo e que no pH 3,5 o incremento no Brix % caldo é superior ao pH 6,8. Para as duas variedades pesquisadas a aplicação do etefon promoveu um incremento significativo no acúmulo de açúcar (Pol % cana) onde os tratamentos com pH de 3,5 promoveram um maior acúmulo de açúcar quando comparado com os tratamentos com pH 6,8. Para a variedade SP84-1431 e SP86-0155 após a primeira avaliação houve uma queda dos valores de açúcares redutores % cana alcançando valores menores aos 69 DAA, porém a análise de variância não indicou nenhuma diferença estatística entre qualquer um dos tratamentos nos diferentes pH. Para a variedade SP86-0155 ocorreu incremento do Brix % caldo e teor de fibra com o decorrer das avaliações para os dois pH testados, porém a análise de variância não indicou nenhuma diferença estatística entre qualquer um dos tratamentos. Para ambas as variedades testadas, os tratamentos com pH da calda de pulverização a 3,5 foram os que apresentaram os melhores resultados.The ripening induction through chemical products is an usual practice in the sugarcane cropping systems in Brazil, being ethephon one of the ripeners extensively used. However, the interaction of factors related to climate and crop physiology in the application timing, with the physical-chemical properties of the ethephon may influence its efficacy. Being the ethephon a weak acid, the pH of the spray solution may interfere with its process of absorption and induction action of ripening in the sugarcane crop. Therefore, the objective of this research was to verify the interaction between the pH reduction of the spray solution with rates of ethephon on the efficacy of ripening induction by the ripener in two sugarcane genotypes. For that it was used two varieties of sugarcane SP86-0155 and SP 84-1431. The treatments resulted from a combination of four rates of ethephon (337.68; 385.92; 434.16 and 482.4 g ha-1) besides a check plot without the ripener application and two spray solution pH (3.5 and 6.8). It was evaluated the technological attributes of the stalks and juice pol % in the stalks, degree Brix in the juice, % of reducing sugars, % of fiber, purity of the juice for both varieties at 4, 23, 37, 51 and 69 days after treatments (DAA), besides productivity of millable stalks and sugar per hectare at 69 DAA for the variety RB 81-5486. For the variety SP 84-1431 there was a tendency that as the ethephon rate increase the Brix % juice also increases, and the in the pH 3.5 the increment of the Brix % is higher than in the pH 6.8. For the variety SP 84-1431 and SP86-0155 after the first evaluation there was a lower decrease in the in the reducing sugar content of the stalks, reaching values lower at 69 DAA, however the analysis of variance did not indicate statistical differences among the treatments in the two pH studied. For the variety SP86-0155 there was an increment in the Brix % stalk and fiber as the evaluations were done, however the analysis of variance did not indicate any difference among treatments. For both studied varieties tested, the treatments with spray solution pH at 3.5 presented better results.

Full textAbstract:
The effects of crop load and berry exposure on the composition of Marlborough Sauvignon blanc grapes and wine from the Brancott vineyard, Blenheim, were explored.
Commercially grown, 2-cane and 4-cane Sauvignon blanc vines were used with a row orientation of north-south. Two exposure treatments were imposed in the following manner: complete leaf removal was undertaken in the fruit zone and 50% shade cloth was erected to give a uniform shading treatment to half the trial vines. Weekly thirty-berry and whole bunch samples were taken from each of the 32 plots with the exception of the veraison period when two samples per week were taken. Vine vigour was assessed using pruning and leaf area per vine data. Harvest occurred on different dates for 2-cane and 4-cane pruned vines so that fruit attained from both treatments had similar °Brix. Fruit was processed at the Lincoln University winery. Must analysis and wine analysis were
undertaken. As expected, 4-cane vines had almost double the yield of 2-cane vines. Higher crop load
significantly reduced leaf area per shoot and shoot thickness. Lower leaf area to fruit ratio
for 4-cane berries resulted in delayed onset of veraison and slowed the rate of sugar accumulation. Crop load, which limited leaf area to fruit ratio, appeared to be the dominant
factor in determining timing of grape physiological ripeness as expressed by °Brix over
other factors such as fruit exposure. Malic acid, tartaric acid, IPMP (iso-propylmethoxypyrazine)
and IBMP (iso-butyl-methoxypyrazine) were lower at equivalent °Brix in 4-cane compared with 2-cane berries. Significantly higher concentrations of quercetin were found in exposed compared to shaded berries. Must analysis showed a significant influence of crop load on berry titratable acidity and pH, reflecting berry ripening results. Exposure significantly increased the concentrations of nitrogenous compounds in 4-cane must yet showed no influence on 2-cane must.
After wine processing lower malic acid concentrations in wines made from 100% exposed
fruit became evident in lower wine titratable acidity but showed no influence on wine pH.
Bentonite addition to wines had a small but statistically significant influence on wine by
reducing pH, titratable acidity and alcohol. Bound sulphur concentrations were significantly
higher in 4-cane versus 2-cane wines. At harvest, methoxypyrazine levels in grapes and wines were very low; IBMP concentrations where significantly lower than those normally found in Sauvignon blanc wines from Marlborough. This was attributed to the absence of basal leaves from the shoots of ripening berries.
The results suggest that leaf area to fruit ratio is a powerful determinant of grape and wine
quality.

Full textAbstract:
Electrical Impedance Spectroscopy (EIS) is a relatively new method applied to food quality assessment. EIS allows relatively inexpensive assessment, is fast, easy to operate and non-invasive. It has been adopted for investigation of fundamental electrical properties of plant tissues. Although the applications of EIS for food quality determination have been reported previously, the analytical relationships between electrical impedance properties and quality criteria have not yet been fully developed. Further exploration is thus important in acquiring more data on electrical impedance characteristics of fruits and vegetables and researching new approaches for determination of their quality. This dissertation aims to investigate the electrical impedance properties of fruits and vegetables, and explore the relationship between impedance and quality criteria. In particular, the present dissertation outlines experimental research conducted on relationships between impedance properties and fruit tastes as well as the impedance changes observed during ripening process. Impedance measurement to monitor moisture content changes in the progress of drying is also included in this research. In summary, the impedance properties have merits in fruits and vegetables quality assessment. The current used subjective visual inspection and assessment could be replaced by the EIS based approach as it is a more precise measurement of food quality. Further study is required to give this method practical value.

Mestrado em Biotecnologia no Ramo AlimentarO presente trabalho foi desenvolvido no âmbito do estágio curricular realizado na empresa Sugal Group, tendo como objetivo desenvolver vários projetos. O primeiro objetivo foi o acompanhar a implementação e a otimização de uma nova linha de produção, tendo ficado definido o tratamento térmico para o produto em questão: tomate pelado inteiro com sumo de tomate, assim como todos os testes e otimizações necessárias da linha para que esta pudesse produzir na próxima campanha de tomate. Seguidamente, de acordo com os objetivos foi delineada e desenvolvida uma gama de novos produtos (sopas), assim como otimizados processos de preparação e de esterilização para as mesmas. Foram aprovadas 4 das 5 sopas tendo em vista o seu desenvolvimento pré-industrial e encontrado o processo de tratamento térmico que mais se adequa às caraterísticas de cada uma delas. Também foi proposto desenvolver e testar um método preditivo de °Brix para aplicação na diluição de vários concentrados, não se atingindo um método definitivo. Foi possível detetar algumas diferenças do °Brix no método de diluição e nos resultados da análise dos diferentes concentrados de tomate, mostrando sobretudo que existe um maior desvio do °Brix do concentrado HB em relação ao concentrado CB e entre estes e o valor °Brix teórico. Por último, testou-se a possibilidade de aplicação do processo de Alta Pressão em sumo de tomate, conseguindo-se obter um sumo seguro e estável à temperatura ambiente através de um processo a 600 MPa durante mais de 3 minutos.
The present work was developed within the curricular internship at Sugal Group, with the aim of developing several projects. The first objective was to follow the implementation and optimization of a new production line, having defined the heat treatment of the product in question: whole peeled tomato with tomato juice, as well as all the necessary tests and optimizations of the line so that it could produce in the next crop. Then according to the objectives, a range of new products (soups) were designed and developed, as well as optimized the preparation and sterilization processes. Four of the five soups were approved for the pre-industrial development and then found the heat treatment process that best suits the characteristics of each one. It was also proposed to develop and test a predictive method of °Brix for application in the dilution of several concentrates, not reaching a definitive method. it was possible to detect some differences of the °Brix in the dilution method and in the results analysis of the different tomato concentrates, showing that there is a larger deviation of °Brix of the concentrate HB and CB and between these and the value theoretical °Brix. Finally, it was tested the possibility of applying the High Pressure process in tomato juice, achieving safe and stable juice at room temperature through a process at 600 MPa for at least 3 minutes

This study reports on an investigation to determine the effects of tube dimensions (different lengths and diameter) and operating conditions on the heat transfer coefficient of a single tube pilot rising film evaporator. The HTC data and the capital cost model developed as part of the study can be used to design an industrial Robert type evaporator with superior performance in terms of higher heat transfer efficiency and reduced costs associated with the design, fabrication, installation of the equipment. The study has also resulted in a better understanding of the boiling mechanism in rising film evaporators and operational recommendations are postulated to increase the performance of existing Robert type evaporators.
