Resumo: Neste trabalho estudou-se a influência da desidratação osmótica, como prétratamento, para a secagem de fatias de banana nanica (Musa cavendishl). O pré-tratamento osmótico foi realizado utilizando-se soluções de sacarose nas concentrações de 35, 50 e 60%. Utilizou-se também como variável do processo a temperatura de desidratação, 25 e 60°C, com agitação constante de 80rpm. No estudo da cinética da desidratação osmótica verificou-se que a temperatura do processo assim como a concentração da solução osmótica tiveram influência significativa nos valores de perda de água e ganho de sólidos das amostras. A etapa de secagem foi realizada utilizando-se duas temperaturas, 40 e 60°C, com velocidade do ar constante de 2,75m/s. Os experimentos foram realizados em secador de leito fixo. O ajuste dos dados experimentais foi realizado utilizando-se a equação de Fick para placa plana sem considerar o encolhimento e também pelo modelo de Page.

Resumo: Este trabalho estudou o processo de obtenção de banana nanica crocante através da secagem a altas temperaturas e curto período de tempo (HTST - High Temperature and Short Time). O processo consistiu de um pré-tratamento a 70°C durante 5 minutos, de uma etapa à alta temperatura (130°C, 1400C e 150°C) e curto tempo (9, 12 e 15 minutos) e de uma etapa à temperatura de 70°C até atividade de água em torno de 0,320. De modo a verificar a influência da etapa HTST no processo, montou-se um planejamento experimental fatorial 22 com 3 pontos centrais, cujas respostas do processo foram o grau de reidratação, o parâmetro k do modelo de Lewis (para a etapa HTST, 70°C e secagem completa) e a crocância, avaliada por medidas sensoriais e instrumentais de textura. O planejamento experimental resultou numa matriz com as condições de ensaios de 130°C-9min, 130°C-15min, 150°C-9min, 150°C-15min e três pontos centrais a 140°C-12min. Banana crocante foi obtida com as condições de 140°C-12min e 150°C-15min de etapa HTST, com atividade de água de 0,345 e 0,363, respectivamente. Os resultados mostram que o melhor grau de reidratação ocorreu para os tempos de 10 e 5 minutos e que existe uma significativa relação entre a crocância e a temperatura da fase HTST. Não foi possível encontrar um ajuste adequado ao parâmetro k do modelo de Lewis para a etapa HTST e a 70°C, porque as umidades iniciais eram diferentes e promoveram grande diferença nos valores desse parâmetro. Adicionalmente, caracterizou-se a crocância de frutas comerciais liofilizadas e determinou-se a aw. Os resultados obtidos para a banana comercial liofilizada foram comparados com os da banana desidratada obtida neste estudo. As medidas instrumentais e sensoriais mostraram que ambas foram consideradas crocantes
Abstract: We present here a study about producing crispy banana using a HTST (High Temperature Short Time) process. The process involves pretreatment of the fruit during 5 minutes at 70°C, a dry HTST stage (130, 140 and 150°C and 9, 12 and 15 minutes) and, finally, a dry stage at 70°C until the water activity (aw) is near 0,300. In order to evaluate the HTST stage in the process, we used a factorial 22 design with 3 center points. The results produced by this analysis were the rehydratation degree, the model parameter of Lewis k (considering either the complete process, the HTST stage and the dry stage at 70°C). Also, crispness was analyzed according to sensorial and instrumental measurements. This process generated a matrix containing the results of several trial runs for the following settings: 130°C-9min, 130°C-15min, 150°C-9min, 150°C-15min and 3 center points at 140°C-12min. Crispy banana was obtained only with 140°C-12min and 150°C15min, where aw = 0,345 and aw = 0,363, respectively. The results show that the best rehydration degree occurs for 10 and 5 minutes. Also, there exists a relationship between the crispness (sensorial and instrumental) and the HTST stage. However, it was not possible to find a suitable value to the Lewis Model parameter k to HTST and 70°C dry stages. This is because the initial moisture of the fruits was not the same for all tests, which produced different values for k. In addition, we evaluated the crispness of commercial freeze-dried fruits and the water activity value. Finally, we compared measurements of the commercial banana with the dried banana obtained in this work. Both were considered crispy

Повний текст джерелаBanana production in the Ribeira Valley, in São Paulo, is set in a region that embraces a remaining fragment of the Atlantic Coastal Forest (Mata Atlântica), considered one of the main biodiversity repositories and the most devastated forest among the Brazilians´ biomes. Sustainable measures such as the adoption of alternative farming practices has been the way for the conservation of fauna and flora, but also to reduce the inappropriate use of land which in turn may increase the disease index that attack plants. Although, reasonable scientific knowledge about banana postharvest physiology is available, the fruit´s physiologic response given the environment changes as a result agroecological practices has not been elucidated yet. Primarily what are the mechanisms of action of specific compounds, related to plant resistance against biotic and abiotic stresses. In addition, there is not an integrated analytical approach to identify regulators of metabolic pathways and enable a holistic study at the molecular level. In this study, we evaluated the effect of proximity to the native biodiversity of the Atlantic Forest on the banana metabolites profile (Musa acuminata AAA, Cavendish, cv. Nanicão). The fruits of Biodiversity group were compared, which has 60% of its perimeter adjacent to the forest with the Control group set in a conventional banana production area. In this study, we determined the ethylene profiles, green life, starch, sugars, texture, colour, semi- volatile and non- volatile metabolites and polyamines. As a result, both evaluated groups showed significant differences in primary and secondary metabolism, green and ripen fruits respectively. The metabolites with significant differences between treatments showed greater involvement in primary metabolism, especially in amino acid biosynthesis, precursors of secondary metabolites. Changes in the abundance of these compounds are indicators that alterations in the environment modify the plant responses to stresses and stimuli.

In tropical regions, intensive banana (Musa accuminata) monocropping has severe agronomic and environmental impacts, and the sustainability of this production is actually highly compromised. Yield reductions are principally due to the decrease of soil fertility and root systems damages by sod fungus and nematodes. Several alternatives actually aim to improve sustainable banana cropping systems. Among them, the cultivation of banana in cover-cropping systems with legumes is a promising one. The development of such systems, however, mainly depends on me knowledge and control of how the mixed component crop competes and affects the production of the principal banana crop. The goal of this study is to estimate the functioning of the banana canavalia ensiformis cover-crop system in field conditions Canavalia is an annual legume that is supposed to have nematode control properties. In this study, however, we focus only on the capacity of banana to perform in such cropping systems, under competition for environmental resources. It is a prerequisite to the development of further investigations uppon bio-control mechanisms that could be managed in integrated protection systems. An analysis of the elaboration of yield components during the vegetative phase of the growing cycle of the banana crop was performed: it is during that phase that the potential yield (number of fruits and fruit filling) is determined, and it is assumed that legume competition can affect yield elaboration. Three treatments were carried out: (i) BPO : banana pure crop, (ii) BA0 simultaneous mixed banana-canavalia, (iii) BA60: -mixed banana-canavalia with banana planted 2 months after canavalia. Growth and development parameter were registered weekly by non destructive methods (leaf area, leaf phenology, stipe height and diameter for banana, and canopy extension for canavalia). Destructive sampling were carried out twice a month to determine above ground dry matter (DM) and mineral composition of banana in the different treatments. In addition to this agronomical evaluation, we developed a banana-intercropped modal adapted from the STICS model for validation and scenario analysis. The analysis of the vegetative cycle of banana over 7 months shows that the plantation date is crucial for the success of the intercrop. There was no significant difference between BP0 and BA0 for DM before flowering (4,5 t MS ha-1 for BP0 against 4,2 t MS ha-1 for BA0). The number of weddings is also significantly reduced for 8 to 3 between BP0 and BA0, respectively. Bananas performances are, however, more affected in BP60. Here, banana DM is reduced lo 2,7 t ha-1, that can be explicated by a higher adverse effect by the canavalia that was dominant at the plantation of banana -- 74 cm height against 29 cm for banana. The performed yield analysis may be considered as an efficient approach for the evaluation of the vegetative phase of the banana, growing sole or intercropped. The analysis of the reproductive phase is actually carried out and should complete this first diagnosis. Model validation under simulated vs. observed data was satisfying. Scenario studies of pure crop situations predicted yield values of 28 ha -1 against 20 t ha -1 (1) in situation with 400 kg nitrogen ha -1 and 133 mm irrigation, (ii) in situations without fertilizers and irrigation, respectively. A simulated yield of 16 t ha-1 was obtained in the case of intercrop without inputs. Test of contrasting scenarios may be used as a decision tool for the definition of adapted intercropping patterns - optimization of plant density and synchronization of the plantation dates of the two species, for instance -, and new agronomical standards may be studied. These investigations, however, must be carried on with the purpose of mean and long term effects evaluation of these cover-cropping systems in relation with the evolution of soil bio-physic-chemical properties - organic matter status and evolution, soil fauna transformation, weeding -, and sustainability.
Nas regiões de clima tropical, o monocultivo da banana vem causando conseqüências ambientais desastrosas e, muitas vezes, impedindo uma exploração continuada de uma mesma área. A redução do rendimento é devido principalmente as limitações físico-químicas do solo e a rápida degradação do sistema radicular, agravada pela ação de parasitas do solo (nematóides, fungos, etc.). Em virtude destas limitações, várias iniciativas vem sendo buscadas para a minimização das perdas agronômicas e ambientais, destacando-se o melhoramento e a modificação genética, e a associação deste cultivo com espécies leguminosas. Porém uma das grandes dificuldades de avaliarmos os novos sistemas de cultivo alternativos concentra-se na falta de referenciais agronômicos relacionados principalmente com o funcionamento de sistemas de cultivos associados, especialmente relacionados aos fatores e condições que interferem diretamente na definição do rendimento da espécie principal. O presente estudo testou , em campo experimental, o uso de plantas de serviço associada a bananeira e seus efeitos na produção de biomassa durante seu o ciclo vegetativo. Isto porque é durante esta fase que a bananeira constrói sua capacidade de reservas de fotoassimilados e, consequentemente, define o potencial de produção e enchimento dos frutos. Além do monocultivo, definiu-se mais duas parcelas associadas com o feijão-de- porco: 1) o plantio simultâneo das duas espécies e; 2) o plantio de feijão-de-porco e, após 2 meses, a introdução da banana. Além de acompanhamento semanal das parcelas, realizou-se, bimensalmente, coletas destrutivas de dados sobre produção de matéria seca, superfície foliar e análise nutricional das plantas. Após a análise agronômica da fase vegetativa, aplicou-se a modelização dos sistemas de cultivo estudados e comparou-se os possíveis cenários sobre o rendimento final da bananeira, além de outros indicadores sobre os fatores de crescimento das plantas. Após o acompanhamento dos 7 primeiros meses do ciclo vegetativo, concluiu-se que a data de estabelecimento da associação foi determinante para o sucesso do cultivo associado. Podemos destacar que a associação entre a bananeira e o feijão-de-porco não causou limitações na produção de biomassa (4,2 ton/ha), quando comparada com o monocultivo (4,5 ton/ha). A redução do número de capinas também foi um indicador animador deste sistema de cultivo alternativo. Por outro lado, quando a bananeira foi plantada 60 dias após a leguminosa, a mesma representou uma séria limitação na produção de biomassa (2,7 ton/ha). Esta limitação deveu-se ao estado de forte competição devido a agressividade com que o feijão-de-porco recobria toda a parcela e alcançando uma altura (74 cm) superior que a muda de banana (29 cm). Em relação a primeira parte da metodologia aplicada - o diagnóstico agronômico -, a mesma foi eficiente para a avaliação do ciclo vegetativo da associação estudada, ficando a necessidade da continuidade do acompanhamento do ciclo reprodutivo, para a confirmação dos resultados em termos de formação e produção de frutos. Na fase de modelização, chegou-se a uma leitura dos resultados próxima dos resultados obtidos no campo. Em termos de rendimento em frutos, o monocultivo com adubação (400 kg/ha de nitrogênio) e irrigação (133 mm) teve um aumento na ordem de 50% no rendimento final (28 ton/ha) Quando comparada com a parcela nas condições reais do experimento (19,6 ton/ha). Já o rendimento em frutos da associação, apresentou o mesmo resultado com e sem adubação e irrigação (16 ton/ha). No tocante a contrução dos cenários, confirmou-se novamente algumas das vantagens da associação, principalmente na redução da adubação nitrogenada aplicada nos sistemas convencionais de cultivo. Finalmente, podemos imaginar a construção de várias formas de testar e otimizar o uso destes sistemas associados (cenários). Porém, confirma-se que a construção de novos referenciais agronômicos sobre sistemas de cultivo mais complexos (os cultivos associados) torna-se ainda muito necessário para a realização de avaliações mais precisas sobre estas alternativas. E, com estes novos referenciais técnicos, podemos imaginar, a médio e longo prazo, alguns dos benefícios das leguminosas sobre as propriedades físico-químicas do solo cultivado (cobertura viva, adubo verde, redução de adventícias, etc) e sobre a manutenção do rendimento dos cultivos (adubação verde).
Dans les régions tropicales, la monoculture de la banane (Musa accuminata) a des impacts agro-environnementaux désastreux, et interdit une exploitation continue de la parcelle en culture. La réduction du rendement de la banane est principalement liée aux limitations physico-chimiques du sol et à la rapide dégradation du système racinaire sous l’action des parasites du sol (nématodes et champignons). Du fait de ces limitations, diverses alternatives sont aujourd’hui proposées pour minimiser les problèmes agronomiques et environnementaux, parmi lesquelles l’association de la culture de la banane avec des légumineuses constitue une voie intéressante. Une des grandes difficultés pour évaluer ces nouveaux systèmes de culture tient à l’absence de références agronomiques sur les systèmes de culture associés, notamment des facteurs et conditions de production pouvant affecter l’élaboration du rendement de l’espèce principale. Cette étude a pour objectif l’évaluation au champ de l’association de la banane avec une plante de service - Canavalia ensiformis – qui en plus d’être une légumineuse fixatrice d’azote, posséderait des propriétés némato-régulatrices. Avant de s’intéresser concrètement à ces propriétés, il importe de mieux comprendre l’aptitude du bananier à supporter la présence d’une plante associée. L’analyse des effets du canavalia sur la production de biomasse de la culture de banane a été suivie durant la phase végétative. C’est en effet durant cette phase que la banane élabore ses réserves en hydrates de carbone et que se définit le potentiel de production et de remplissage des fruits. Trois traitements ont été étudiés sous l’angle de l’élaboration des composantes du rendement de la banane : (i) BP0 : banane en culture pure, (ii) BA0 : banane associée au canavalia en plantation simultanée, (iii) BA60 : banane associée au canavalia en respectant un décalage de 2 mois entre la plantation du canavalia et la plantation de la banane. Un suivi hebdomadaire non destructif des paramètres de croissance et de développement des 2 espèces sur les 3 parcelles a été réalisé (surface foliaire, rythme de développement des feuilles, hauteur et diamètre du pseudo-tronc pour le bananier, extension du couvert du canavalia), et des prélèvements destructifs de biomasse de bananier ont été effectuées 2 fois par mois permettant l’analyse de la nutrition minérale des plantes. En parallèle à cette évaluation agronomique, une modélisation de la culture de la banane a été réalisée sur la base du modèle STICS, et différents scénarios de systèmes de cultures ont été étudiés. Le diagnostic portant sur les 7 premiers mois du cycle végétatif montre que la date de mise en place de l’association est déterminante pour le succès de la culture associée. L’association simultanée de la banane et de la légumineuse (BA0) ne provoque pas de réduction significative de la biomasse produite (4,5 t MS ha-1 pour BP0 contre 4,2 t MS ha-1 pour BA0). La réduction du nombre de sarclages pour BA0 est également très significative (8 sarclages en BP0 contre 3 en BA0). En revanche, dans le traitement BA60, la culture de banane subit une série de limitations. La production de biomasse est très affectée (2,7 t MS ha-1), et s’explique par une compétition plus forte exercée par le canavalia qui est beaucoup plus couvrant et qui atteint une hauteur de 74 cm, supérieure à celle de la banane en début de cycle (29 cm). L’analyse des composantes du rendement s’est révélée une méthode efficace pour évaluer la phase végétative de l’association étudiée ; l’analyse de la phase reproductive est en cours et devrait compléter cette première évaluation. La validation du modèle a été probante en permettant de simuler des résultats proches de ceux obtenus sur le terrain. Des études de scénarios ont permis des prédictions de rendement de 28 t ha-1 contre 20 t ha-1, pour le traitement en banane pure, conduit respectivement (i) avec une fertilisation de 400 kg d’azote ha-1 et une irrigation de 133 mm, (ii) sans apports d’engrais. Le rendement de l’association sans fertilisation et sans irrigation atteint 16 tonnes de fruits par hectare. La construction de différents scénarios peut donc être conduite dans la perspective de tester et d’optimiser les modalités d’association : optimisation des densités de plantation et du calage des cycles, par exemple. La construction de nouveaux référentiels agronomiques sur ces bases est donc possible. Ces travaux se doivent d’être poursuivis em vue d’évaluer les effets à moyen et long terme de ce type d’association sur l’évolution des propriétés bio-physico-chimiques du sol cultivé et de sa fertilité - évolution de la matière organique en relation avec les restitutions de la plante de service, évolution de la faune et de la flore du sol, contrôle des mauvaises herbes – , pour statuer sur la durabilité de ces systèmes de culture.

Повний текст джерелаOver decades synthetic composites have become an indispensable part of our lives with their various applications such as packaging, sporting equipment, agriculture, consumer products, medical applications, building materials, automotive industry, and aerospace materials among others. Although these polymers have the desired properties for the above applications, they are invariably costly. Furthermore, they cannot be easily disposed of at the end of their useful lives and simply pile up and cause significant damage to the environment. However, the dwindling supply of fossil fuel, increased oil prices, together with the growing public concern of greenhouse gas emissions and global warming, has forced scientists to search for new development of sustainable materials from renewable resources. Hence in recent years, there is an increased interest in biocomposite manufacturing with natural resources as environmental issues are addressed. The research work presented in this dissertation is to the best of the author’s knowledge a world-first overall investigation pertaining to the concept of synthesizing a banana sap based bio-resin (BSM) reinforced with banana fibres. In this work the chemical composition of banana sap was determined to investigate the chemical reactions taking place in the resin formulation. BSM was synthesized, characterized and proposed as a potential bio-resin to be used in the biocomposite manufacture for non-functional motor vehicle components. BSM, a hybrid bio-resin was synthesized with equimolar quantities of maleic anhydride and propylene glycol and 50% banana sap. A control resin without the banana sap was also synthesized for comparison purposes. It was proposed that the presence of sugars, esters and pthalates from the sap, determined by HPLC and GC-MS, contributed to the cross-linking of the polymer chain. The acid value and viscosity of BSM were determined and found to be within specification of an industry resin. The molecular weights of the BSM and control resins were 2179 and 2114 units respectively. These were within the required molecular weight of unsaturated polyester resins. The gel and cures times of the BSM were 60% lower than the control resin suggesting that the banana sap behaved as an accelerator for the curing process. The lower cure time meant that using the banana sap in the formulation was cost effective and time saving. The thermal properties of BSM showed improved degradation temperatures and degree of crystallinity compared to the control resin. A parametric study showed that increasing banana sap concentration in the resin formulation led to increased tensile and flexural properties with 50% being the optimum amount of sap to be added to the formulation. The synthesized bio-resin and control resin were applied to biocomposites and characterized in terms of physical, thermal, mechanical, morphological, chemical and biodegradable properties. Mechanical tests indicated a 15 % increase in tensile strength, 12 % improvement in tensile modulus and a 25 % improvement in the flexural modulus, when compared to structures produced without banana sap. Natural fibres present the challenge of poor adhesion to the matrix. Chemical treatment of the banana fibre was done to improve on the compatibility of resin to fibre. Fibre pull-out showed that treated fibres had a better bond than the untreated fibre. Parametric studies were also done to evaluate the effect of fortifying the BSM resin with nanoclay. A 5% clay loading resulted in a 24% increase in tensile strength and 28% increase in flexural properties. Finally biodegradation studies of the BSM bio-resin, BSM biocomposite, control resin and control composite were investigated and compared to a positive reference, cellulose. Results showed that over a period of 55 days the BSM biocomposite showed 17.6% biodegradation compared to 8% with the control composite. No difference in biodegradation between the BSM bio-resin and the control resin was recorded. BSM biocomposite was proposed as a potential replacement to synthetic composites that contribute to the environmental landfill problems. The main contribution of this research is the use of the reinforcement and matrix from the same natural source. An enriched understanding of the synthesis, characterization and performance of the banana sap based bio-resin and biocomposite for the use of non-functional motor vehicle components is the key outcome of this investigation.
