Abstract:
Abstract Percentage ingredient labeling has been proposed for baby foods. We determined whether or not the potassium content of baby foods could be used to verify the quantity of fruit when the characterizing ingredients were apricots or bananas, fruits rich in potassium. Official values for potassium in fruit (USDA Handbook No. 8-9) did not agree well with actual analyses. The potassium levels of products of known composition were accurately predicted from analyses of the actual ingredients used to make the foods. For banana-containing monofruit products of variable or unknown composition, potassium analysis led to fruit level estimates consistent with either the known composition or the label declaration. For products of unknown composition made with apricot concentrate, however, potassium analysis led to fruit level estimates lower than the probable fruit content. The quantity of fruit in baby foods made with potassium-rich fruits can be estimated from the potassium content if the potassium value for the fruit is representative of the actual ingredients used to make the product, if potassium analysis is to be used to verify compliance with percentage ingredient labeling, there must be statutory specification of the singlestrength fruit level for fruit reconstituted from concentrate.

Abstract:
Paper discusses the effect of vibrations at different frequencies on changes in the content of ascorbic acid and citric acid in blueberry fruit. Fruit was tested under incomplete maturity. The chemical com-position of fruits was compared immediately after harvest, stored and subjected to vibrations. The purpose of the research was to deter-mine the effect of vibrations on the degree of fruit ripeness. Studies have shown that vibrations at low frequencies did not affect changes in the chemical composition of blueberry fruit. Vibrations with a frequency of 28 Hz caused significant changes in the parameters tested in the fruit.

Abstract:
Yellow pitaya, Selenicereus megalanthus (Schum. ex. Vaupel) Moran, is a potential new fruit in Taiwan. It sprouts mostly in winter and flowers in late spring and fall. In this study, an average of 60% shoots within canopies flowered. Shoots sprouted in the current winter flowered in fall and produced winter fruits, and shoots sprouted earlier than the current winter flowered in late spring and produced summer fruits. Floral buds on most shoots appeared at the distal end. The weight, pulp percentage, and total soluble solids of winter fruits were significantly higher than those of summer fruits. The number of black seeds was positively correlated with pulp weight (R2 = 0.87). The total soluble solids in the core region of winter fruits reached 22.7 °Brix, higher than that in other regions. Future efforts to improve yellow pitaya production in Taiwan include increasing winter fruit production by enhancing growth of the current year's new shoots through proper canopy management and increasing the size of summer fruit by artificial pollination, fruit thinning, and other means.

Abstract:
Eugenia brasiliensis Lam. is a variable species concerning fruit colour, with three recognized varieties. However, the definition of varieties is not easy for Myrtaceae species and not widely accepted. Two fruit colour varieties (purple and yellow) of E. brasiliensis had their essential oil composition analysed in order to give support to the existence of varieties for this species. Although, the major components in the leaf oil are the same monoterpenes for both varieties, alpha-pinene, beta-pinene and 1,8-cineol, the purple fruit variety accumulates more oxygenated sesquiterpenes (33.9%) than the one with yellow fruits (3.8%). The major differences occurred in purple fruits that present as major components caryophyllene oxide (22.2%) and alpha-cadinol (10.4%), not found in the leaf oil, and the yellow fruit oil presented a similar composition as observed for the leaves. These fruit colour varieties of E. brasilensis can be considered as two distinct chemotypes, since the sesquiterpene pathway is more operant in the purple variety than in the yellow one, in which monoterpenes are mainly accumulated.

Abstract:
Effect of micronutrients on leaf composition, quality parameters and fruit yield of Kinnow mandarin was studied at Regional Research Station, Abohar. Foliar application of 1000 ppm Zn + 1000 ppm Mn on Kinnow mandarin during the end of April and mid of August gave maximum fruit yield (862 fruits / tree) and good quality fruits (Higher TSS/Acid: 14.23) by correcting these micronutrient deficiencies. Therefore, application of this dose of micronutrient combination will improve yield and fruit quality in Kinnow mandarin by correcting the deficiencies of these micronutrients as a result of which the orchardist will be economically benefited.

Abstract:
ABSTRACT Influence of Crop Load on Fruit Composition Using Pinot Noir Grapes Patrick G. Phelan November 2009 The two seasons for this trial were conducted in 2002 and 2003 at Bien Nacido Vineyard in Santa Maria, California. The trial consisted of pinot noir wine grapes clone 2a, grown on 101-14 rootstock. There were eight treatments with a control consisting of 25 vines per treatment, and 50 vines for the control. The primary objective of this research experiment was to conduct different vine balance procedures and compare them to the amount of wine phenolics. The vines were altered with two procedures. First was crop yield; fruit thinning altered the treatments by providing four different crop loads and a control. The treatment levels were signified as one ton, two ton, three ton, four ton, and control. The second procedure was timing of fruit thinning. Four different crop loads were split in half giving rise to eight treatments and a control. With four of the treatments the fruit was dropped post-bloom, and the other four treatments were dropped at seventy five percent veraison. Equal amounts of early and late thinning were combined and made into wine which gave four different crop load wines and a control wine. This process was done in 2002 and repeated in 2003. Additionally, other vine growth parameters were analyzed to determine the role that crop load and timing of thinning had in their development. Seven variables were analyzed from prunings, clusters, juice, and wine samples. They consisted of berry size, cluster weight, titratable acidity, pH, total soluble solids, phenolic profile (consisting of eleven components), and shoot weight. The results indicated that the following were statistically significant: (1) titratable acidity was significantly different between the 2002 and 2003 growing seasons, (2) total soluble solids showed a significant difference between the early fruit thinning versus the late thinning, (3) berry size in 2002 showed a statistically significant effect of drop date on the mean caliper size, (4) in 2002 the berry size also showed a statistically significant interaction between drop level and drop date, (5) berry size in 2003 showed a statistically significant effect of drop level on the mean caliper size, (6) in 2003 there is also a statistically significant effect of drop date on the mean caliper size, (7) again in 2003 there is a statistically significant interaction between drop level and drop date, (8) cluster weights in 2002 showed a statistically significant relationship between drop level and average cluster weight, (9) in 2002 cluster weights also showed an effect of the time of fruit drop on the average cluster weight, (10) cluster weights in 2003 showed a statistically significant relationship between drop level and the average cluster weight, (11) pruning weights in 2002 showed a statistically significant relationship between drop level and average shoot weight, (12) pruning weights in 2003 showed a statistically significant relationship between drop level and average shoot weight and finally, (13) of the eleven phenolic components measured, five differed significantly by year but not across the five treatments. Information derived from this experiment suggests that the site is a high vigour location according to Robinson and Smart’s yield to pruning weight ratio. With this in mind we find that TA and pH were not a significant factor, but soluble solids (brix) ascertained a higher degree of brix with the late drop treatment. We conclude this to be an effect of both the high vigour site and more uniform fruit drop. In 2002 and 2003, we find a significant interaction between drop date and berry size with a late drop producing the smallest berries on average. Cluster weights varied between 2002 and 2003 and the results were inconclusive. Shoot weights along with harvest totals concluded a high vigour site. The one ton level in 2002 had a significantly higher average shoot weight than the three ton level (p<.001), four ton level (p=.006), and no fruit drop control (p<.001). There is also a significant relationship between drop time and average shoot weight in 2002 (p<.001), and 2003 (p=.049) with the late fruit drop being followed by a lower shoot weight. This significant relationship expressed that an early drop increased the shoot weight which contributed only more vigour to an already high vigour site. The ratio of yield to pruning weight for 2002 gave us a range of .39 to 1.78, and in 2003 the range was .32 to 1.36 concluding a high vigour site. The phenolic profile expressed a statistical difference by year, but was most likely caused by a varying fermentation temperature or different climatic conditions in 2002 and 2003.

Donetti, Manuela. "Postharvest biochemical and physiological characterisation of imported avocado fruit." Thesis, Cranfield University, 2011. http://dspace.lib.cranfield.ac.uk/handle/1826/7672.

Abstract:
Difficulties in controlling and forecasting avocado fruit ripening and the highly perishable nature of the crop once harvested, are the major causes of concern for avocado traders. In particular, the simultaneous presence of many suppliers may account for increased fruit variability during ripening. Avocado is a climacteric fruit with consistent ethylene production after harvest which is also related to high perishability. However, the mechanisms regulating ethylene biosynthesis and mesocarp softening are not completely understood. In order to study such effects, avocado fruit from different growing areas and harvested at various maturity stages, were investigated and the biochemical and physiological changes during ripening at both 18 and 23°C were studied. Mesocarp softening and fatty acid content discriminated fruit maturity and growing area, respectively, whereas C7 sugars (D-mannoheptulose and perseitol) discriminated length of fruit shelf life. For the first time, oleic acid content presents in the oil mesocarp was found to depend on fruit sources making of this a suitable indicator of avocado fruit growing area. In contrast, sugar content declined along fruit maturity and ripening. In particular the mannoheptulose presents in avocado mesocarp might be use to estimate avocado fruit shelf life. Indeed, fruit harvested late in season were found to have a lower C7 content than earlier harvest fruit and a faster softening, regardless fruit source. However, sugars content changed between growing area, thus a general C7 threshold defining fruit storability seems to be not definable. Furthermore, other possible indicators of fruit maturity and/or ripening stage have been searched in the cell wall constituents of avocado mesocarp. Thus, the structural carbohydrates profile of avocado mesocarp investigated with a new immunological method changed during ripening and harvest time (early and late season), suggesting a possible effect of cell wall composition on fruit ripening regulation. Also, the possible use of ethylene application in reducing the high heterogeneity noted on imported fruit from South Africa was also evaluated through different consignments. Results showed ethylene efficacy changed depending on harvest time and fruit dimension with less efficacy of the treatment on fruit harvested at the end of the season and characterised by smaller size.One of the most commercialized avocado cultivars, Hass, is peculiar in that its skin colour changes from green to deep purple as ripening progresses. The most common ripening indicator of avocado fruit is the mesocarp firmness and the destructive nature of this evaluation increases losses in the avocado industry. The availability of a non-destructive indicator of fruit ripening represents an important advantage for avocado consumers and importers. Thus, the possible relationship between mesocarp softening, skin colour were objectively evaluated (C*, L*, and H°), and the main pigment, cyanidin 3-O-glucoside, was investigated. Cyanidin 3-Oglucoside was confirmed to be the main anthocyanin present in avocado cv. Hass peel, regardless of preharvest factors. However, differences in its content were noted between shelf life temperatures. A higher relationship between hue angle and firmness was detected in late harvest fruit, whereas no correlation was found between anthocyanin content and firmness. Avocado skin is also involved in defence mechanisms due to the presence of antifungal and phenolic compounds. These phenolic compounds represent a natural protection against pathogenic infections and seem to be down regulated during ripening. The main phenolics were identified and quantified, using a new analytical method which was validated and optimised. Epicatechin, chlorogenic acid and procyanidin B2 were found to be present in the skin tissue and quantified using this assay and found to vary during shelf life and seasons. Although phenolics were present in minor amounts, in avocado pulp they are involved in mesocarp discoloration incidence, and therefore with fruit postharvest quality. Due to a lack of information, a new straightforward method for the identification and quantification of the main phenolics present in avocado mesocarp was developed. Finally, a commercial trial was undertaken to ensure that the results obtained in the laboratory can be reproduced in the market place. In conclusion, postharvest markers can define avocado fruit maturity and growing area and give guidelines in the control of avocado shelf life. Moreover, new methods for the investigation of the phenolic profiles (peel and mesocarp) and the characterisation of cell wall structures can be further tools in the management of avocado fruit postharvest quality.

Abdoh, Yousef. "Chemical composition and antioxidant activity of date palm Fruit (Phoenix dactylifera) in Saudi Arabia." Thesis, University of Nottingham, 2018. http://eprints.nottingham.ac.uk/51308/.

Full text
Abstract:
Dates are the fruit of the palm, which the Greeks call “Phoenix”, a word taken from the Phoenician language. Saudi Arabia is currently one of the largest dates producing countries in the world. There are several varieties of dates grown in Saudi Arabia. Date fruits contain compounds that are potentially bioactive, with many health benefits; for example, vitamin E, carotene (precursor for vitamin A) and phenolic compounds. Dates represent an excellent source of antioxidants due to their high concentrations of phenolic compounds as well as the presence of selenoproteins. Moreover, dates are also potentially a very good source of several minerals in fact; there are at least 15 minerals found in dates. The work presented in this thesis will determine the nutritional composition of nineteen varieties of dates sourced from four, environmentally diverse, regions in Saudi Arabia. These varieties were selected because of their popularity, economical price, as well as availability during the year. The results indicated that the range of moisture contents (10% - 30%) found within the four regions were quite similar. For levels of fat, protein and ash all varied significantly between varieties but were all very low. Carbohydrate content was variable between samples (70 - 80%). The results indicated that glucose and fructose concentrations in theses Saudi dates were generally similar and the present of sucrose being normally associated with a corresponding reduction in the level of glucose and fructose. Potassium was the major mineral found in all the varieties with concentrations as high as 1173.29 mg/100g. The mean values for phosphorus in the dates from the different regions were close to each other. The amount of selenium was generally very low in all varieties and some did not contain any selenium at all. It would appear that it is variety and not region of production that has the major impact on nutritional composition. Moreover, this research will also determine the antioxidant capacity and phenolic content of a sub-set of these varieties at four different stages of ripening. Results showed that the levels of phenolics, anthocyanin and antioxidant capacity all decreased throughout development in all the seven selected varieties. There were strong correlations between this antioxidant capacity and the total phenolic and anthocyanin levels suggesting that these are major contributors to this nutritional property of dates. A preliminary screen tentatively identified some phenolic compounds and indicates that there may be some compositional variation between date varieties.

Abstract:
The influence of soil texture on canopy growth, vine yield, and fruit composition of Sauvignon blanc were assessed on a mature vineyard from the Rapaura area in Marlborough. The subject vines were mature Sauvignon blanc in a commercial vineyard trained to four cane VSP and planted with a north south orientation. Row and vine spacings were typical of the area at 3m x 1.8m. Four areas of different soil texture were identified using trunk circumference measurements, visual assessment of the surface soil and aerial photographs to identify changes in vine growth. Soil pits were excavated at a later date to determine root numbers and record the soil texture in the different areas. Two crop treatments were imposed on half of the plots at approximately 50% veraison: unthinned crop and 50% crop. A shading treatment was also imposed at 50% veraison where three sets of tagged shoots had bunches that were exposed to sunlight, bunches that had some natural shading from leaves or bunches that had paper bags fastened over each to provide a completely shaded environment. Vine vegetative vigour for each plot was assessed during the growing season using the Point Quadrat method and at pruning using bud counts and pruning weights. Thirty berry samples were collected from the 32 plots and analysed weekly for soluble solids and berry weight. Harvest of bunches from the tagged shoots occurred on two different dates with the first harvest picked when fruit from one soil and crop treatment had reached 21 °Brix. The second picking took place just before the commercial harvest, which coincided with last soil and crop treatment reaching 21 °Brix. Bunches from each tagged shoot were weighed, frozen and later analysed for soluble solids, pH, organic acids, and methoxypyrazines. Vines on very stony textured soils had small trunk circumferences with a high root density and yield to pruning weight ratio compared to those growing on deep silt soils. Vines on deep silt soils had more vigorous canopies with large shoots and a higher leaf layer number. The target soluble solids was reached first by the vines on the very stony plots despite the higher crop load with soil texture appearing to be a dominant factor by influencing the time of flowering. Cluster shading decreased soluble solids, consistent with other studies, whilst crop thinning resulted in an earlier harvest. This was contrary to popular opinion that crop thinning at veraison would have no impact on sugar accumulation. pH and organic acids were unaffected by shading or bunch thinning. Vines growing on deep silt soils had a significantly higher level of total acidity and malic acid than those on the stony soils. At harvest, methoxypyrazine levels were very low compared to previously reported figures for Marlborough, which may have been a result of sample preparation. IBMP was significantly higher on deep silt soils, however, with no impact from the shading or crop treatment. The findings are consistent with the hypothesis that IBMP synthesis may be increased by the number of leaves surrounding bunches (Roujou de Boubee, 2003). The results suggest that soil texture plays a dominant role in influencing Sauvignon blanc flavour and aroma and due consideration should be given to vineyard layout and site selection prior to new plantings taking place.

Abstract:
The consumption of blueberries in the UK is increasing, but currently most of the available blueberries are imported. There is therefore great potential for UK growers to supply high quality blueberries to meet the consumer preferences. At present little is known regarding specific UK consumer sensory preferences, the relationship between fruit metabolite and sensory profiles or the impact of UK climatic conditions on fruit metabolite profile in relation to sensory and health beneficial characteristics. The aim of this study was to understand the sensory expectations of UK consumers and the relationship between fruit phytochemistry and sensory profiles in order to provide underlying tools to assist in breeding of an elite UK adapted germplasm. Sensory tests were conducted on a range of currently grown cultivars. Free-choice profiling identified the range of descriptors used by consumers and subsequent descriptive profiling using the consensus vocabulary resulted in the generation of a multivariate product space describing relationships between the cultivars. The most important attributes were size, sourness and sweetness. The assessors had difficulties in differentiating between aroma, because of the limited flavour volatiles profile. Sugars, organic acids, polyphenols, anthocyanins, flavour volatiles, lipids and brix were quantified to establish links between phytochemicals and sensory character. Sugar and organic acids were the major determinants of sensory scoring for flavour characters. Limited genetic influences were observed in phytochemical content of individual cultivars grown in the same location, based on the similar pedigrees of the cultivars. Environmental influences were manifested as differences in the same cultivar across seasons or growing locations. This study highlights the need for the development of a more diverse product offering. In the short term, further research on the environmental impact on blueberry chemistry should be conducted leading to the development of growing practices that enhance metabolites associate with favourable sensory properties. In the longer term breeding of flavour intensive cultivars is required and the work presented here linking fruit chemistry to sensory properties provides a valuable resource for the indirect breeding of varieties with an appropriate sensory profile.

Abstract:
Les résultats de cette étude de la composition du fruit à pain récolté sur un territoire contrasté du point de vue agropédoclimatique, et de son amidon, montrent que la teneur en amidon du fruit à pain apparaît comme étant influencée par la saison, mais pas par la zone de récolte. La teneur en amidon beaucoup plus élevée pour les fruits à pain développés durant la saison la plus sèche est un résultat très original. La connaissance du cycle de développement des fruits à pain à la Martinique a été décrite pour une première fois, permettant de déterminer une période de récolte optimisée par rapport à la floraison : la 16ème semaine pour une croissance maximale, ou la 17ème semaine pour une plus haute teneur en amidon. L’étude de Worrell et al., (1998), la seule publiée actuellement, menée à la Barbade, a montré un cycle plus long de 2 semaines environ.Du point de vue de la diversité génétique, les fruits à pain récoltés en Martinique constituent un seul groupe, à l’opposé de ceux récoltés en Guadeloupe qui constituent 2 sous-groupes proches.En ce qui concerne l’amidon, nos résultats montrent que les dimensions des grains d’amidon de fruits matures sont comprises entre 9 et 12 µm. Leur taille augmente avec la croissance du fruit puisque dans un fruit immature leur diamètre moyen était de 7,5 µm. Il s’agit d’amidons de type B à très haute cristallinité, dont les températures d'empesage sont autour de 75 °C. Parmi les facteurs agropédoclimatiques, l’humidité a eu un rôle actif sur la qualité de l’amidon puisque à la fois la quantité d’amylose et la masse molaire de l’amylopectine diminuent. L’amidon a une solubilité et un gonflement faible du même ordre de grandeur que les amidons classiques et une forte viscosité à la gélatinisation et à la rétrogradation, lui conférant une aptitude à l’utilisation comme gélifiant.Des essais d’applications alimentaires ont été effectués en panification et en extrusion. Des transformations en produits de type crackers ont donné des résultats moyennement satisfaisant avec 100 % de farine de fruit à pain. En panification l’incorporation de farine de fruit à pain a des actions délétères sur la valeur boulangère. L’acceptabilité d’un goût « nature, vert » conféré par la farine de fruit à pain devra notamment être évaluée lors de travaux ultérieurs.Le développement de produits à base de fruit à pain permettra
The results of this study the composition of breadfruit harvested in an area of agro climatic soil contrasting views, and its starch, show that the starch content of breadfruit appears to be influenced by season, but not by collection area. The starch content is much higher for breadfruit developed during the driest season is a very original result. Knowledge of the development cycle of breadfruit in Martinique has been described for the first time, to determine an optimal harvest period compared to flower: the 16th week for maximum growth, or the 17th week for a higher starch content. The study by Worrell et al., (1998), the only currently published, conducted in Barbados, showed a longer cycle of about 2 weeks.From the perspective of genetic diversity, breadfruit harvested in Martinique as a single group, in contrast to those collected in Guadeloupe that are close to two subgroups.With regard to starch, our results show that the size of starch granules of mature fruits are between 9 and 12 microns. Their size increases with the growth of the fruit as an immature fruit in their mean diameter was 7.5 microns. This is B-type starches with very high crystallinity, with temperatures of gelatinization are around 75 °C. Agro climatic soil factors, humidity took an active role on the quality of starch, since both the amount of amylose and amylopectin molecular weight of the decline. The starch has a solubility and low swelling of the same order of magnitude as the conventional starches and high viscosity to gelatinization and retrogradation, giving it a suitability for use as a gelling agent.Testing of food applications were made in bakery and extrusion. Changes in products like crackers gave moderately satisfactory results with 100 % breadfruit flour. Incorporation into bread flour breadfruit has deleterious actions on the baking. The acceptability of a taste "nature green" conferred by the breadfruit flour will be particularly assessed in future work.Product development based breadfruit allow several things, which meet the growing demand for food diversification

Abstract:
La consommation de fruits est encouragée pour leur apport de composés bioactifs naturels. Ce travail a pour objectif de caractériser dix fruits indignes de la région amazonienne. La caractérisation a été effectuée initialement par des analyses bromatologiques, suivies de la détermination des minéraux Ca, Cu, Fe, Li, Mg, Mn, Na et Zn par spectrométrie d'émission optique ˆ plasma couplé par induction (ICP OES). Ensuite, la capacité antioxydante des fruits a été évalué à l'aide de différentes méthodes colorimétriques (DPPH, ABTS et NBT), ainsi que l'activité antiproliférative contre la lignée cellulaire du cancer du colon humain (caco-2). La composition phénolique a été déterminée par chromatographie en phase liquide à ultra haute performance (UHPLC) couplée à la spectrométrie de masse à haute résolution. Considérant les inconvénients des méthodes conventionnelles de détermination de la capacité antioxydante, un biocapteur enzymatique ampérométrique a été mis au point en utilisant comme transducteur un systéme de trois électrodes sérigraphiées sur PVC, contenant du bleu de Prusse (PB) comme médiateur électrochimique. Une capacité antioxydante lipophile élevée a été observée dans les pulpes de biriba et de bacuri, alors les fruits abiu, inaja et monguba présentaient une capacité antioxydante hydrophile importante. L'activité antiproliférative des fruits de biriba, inaja, monguba et pajura a entrainé une inhibition significative de la croissance cellulaire de caco-2. L'analyse chromatographique des extraits de biriba, inaja et monguba, a permis de quantifier respectivement 11, 25 et 21 composés phénoliques dotés d'activités biologiques importantes
Fruit consumption is encouraged for their contribution of natural bioactive compounds. This work aims to characterize ten indigenous fruits of the Amazonian region. Characterization was performed initially by bromatological analyzes, followed by the determination of Ca, Cu, Fe, Li, Mg, Mn, Na and Zn minerals by Inductively Coupled Plasma Optical Emission Spectrometry (ICP OES). Then, the antioxidant capacity of the fruits was evaluated using different colorimetric methods (DPPH, ABTS and NBT), as well as the ant proliferative activity against the human colon cancer cell line (caco-2). The phenolic composition was determined by ultra high performance liquid chromatography (UHPLC) coupled with high-resolution mass spectrometry. Considering the disadvantages of conventional methods of determining antioxidant capacity, an amperometric enzyme biosensor has been developed using as a transducer a system of three screen-printed electrodes on PVC, containing Prussian blue (PB) as electrochemical mediator. A high lipophilic antioxidant capacity was observed in biriba and bacuri pulps, so abiu, inaja and monguba fruit had significant hydrophilic antioxidant capacity. The antiproliferative activity of the fruits of biriba, inaja, monguba and pajura resulted in significant inhibition of caco-2 cell growth. Chromatographic analysis of birib‡, inaj‡ and monguba extracts quantified respectively 11, 25 and 21 phenolic compounds with important biological activities

Abstract:
Fruits are a relevant source of phenols and ascorbate, biomolecules which scavenge reactive oxygen species. For this reason, they are considered as healthy for the human being. Fruits quality depends on their levels of antioxidants and enzyme activities that ensure their conservation. The aim of this work was to plan and execute a laboratory class of Enzymology, a discipline of Biochemistry degree of University of Évora, Portugal, for determining the functional and conservation value of three different fruits types, sold in the market of Évora, Portugal. The development of this activity allowed that students of a pilot class participate in a laboratory activity which intended to compare the content of phenols, ascorbate, and polyphenol oxidase enzyme activity present in apple, peach and blueberries pulp. At Lab activity, the students successfully determined markers of functional and conservation value of selected fruits. The skills acquired by the students, in terms of obtaining fruit pulp and their composition in antioxidants, stimulated their commitment degree on the application of biochemistry in the everyday, acquiring thereby significant learning, with a high degree of satisfaction.

Abstract:
In developing future electrical networks, it is crucial to develop new alternatives insulating materials which can improve the performance of the next generation high voltage cables. The high electric field reduces the resistance of solid insulation and causes partial discharge occurs through the impurities in a dielectric where this phenomenon causes ageing to the dielectric and ultimately leads to breakdown. Thus, this paper seeks to analyse the electric field intensity of High Density Polyethylene (HDPE) when added with 10%, 20% and 30% of different types of bio-filler such as coconut coir fibre, pineapple leaves fibre, and oil palm empty fruit bunch. This can be achieved by creating a two-dimensional (2D) axisymmetric electrostatic model by using the Finite Element Method Magnetics (FEMM) 4.2 software. The results showed that the inclusion of bio-filler in HDPE increased the maximum electric field intensity when compared with unfilled HDPE. The electric field intensity also varied with the different percentages loading of biocomposite and their permittivity. As a result, the maximum electric field intensity was much lower for HDPE added with a 10% loading of the oil palm empty fruit bunch. Hence, oil palm empty fruit bunch was the best composition as it tends to improve the dielectric properties since it has a lower electric field intensity at the top sphere electrode as compared to other compositions.

Abstract:
Date palm (Phoenix dactylifera L.) is the main fruit crop found in the arid and semi-arid regions of the world. It naturally adapts to the adverse environments of extreme heat and water scarcity and prevents further desertification in addition to producing fruits with high nutritional value. It is seen in many parts of the world that traditional cultivation practices such as mixed planting and chemical fertilizers have led to low fruit quality resulting in low market values. Long generation time also hinders production of the dates. Tissue culture is therefore considered the most promising solution for rapid large-scale production of trueto- type clonal plants. The plantlets originating from in vitro callus proliferation are transferred from synthetic media to soil. The conventional method of using chemical fertilizers also leads to low plantlet viability with increased environmental and health risk. The current research targets the use of a local microalga, Tetraselmis sp. QUCCCM8, identified as an organic source of nutrients, a substitute for chemical fertilizers to acclimatize cultured date palmlets to soil. Soil was supplemented with different concentrations of algal biomass and plant growth was monitored for 3 months. Soil without any fertilizer and soil amended with 1 g conventional fertilizer were used as negative and positive control, respectively. Supplementation with 0.5 g of algal biomass led to higher plant growth rates, 100% survival rates, high ability of rooting (3.17 ± 0.14 roots), higher number of leaves (2.5 ± 0.25 leaves), largest stem thickness, longer shoot (33.75 ± 1.56 cm), and higher total chlorophyll (159.61 ± 9.6 mg L⁻ ¹) as compared to conventional fertilizer. These stated findings are significantly higher than the control. Furthermore, elemental analysis of the soil showed that supplementation with algal biomass increased the soil total nitrogen, potassium, and phosphorus contents essential for plant growth. Finally, the comparison of heavy metals composition between soils amended with conventional fertilizer and algae-based fertilizer highlights the potential use of algae as a safe and efficient biofertilizer post tissue culture mode of plantlet generation. This enhanced the viability of healthy plantlets without affecting the environment, averting usage of chemical fertilizers.

Abstract:
Background: Prevalence of obesity and overweight has risen to the level of an epidemic. Health policy makers are seeking evidence-based solutions to this problem. This study reviews evidence on the subsidization of healthy foods as a fiscal tool to aid-in the public health response to this epidemic. Methods: A systematic search of the major databases was performed, and data extracted from studies meeting inclusion criteria. Main outcomes of interest were indicators of purchasing/consumption pattern, or body composition. Preliminary results are presented as a narrative summary. Results: Search results yielded 22 studies, of which 10 were extracted and 12 excluded. Of the 12 excluded 5 were duplicate studies of reports extracted, and 7 studies did not meet inclusion criteria. Most extracted studies were randomized control trials. The majority of the studies had multiple arms, one of which was typically a multi-component fiscal measure implemented alongside education or skills building. This type of multi-component intervention yielded the most promising results, mainly an increase in the percentage of daily fruit and/or vegetable consumption. This percentage increase varied between studies ranging from 4% up to 35%, with fruit consumption/purchasing responding more favorably to pricing changes compared to vegetable consumption/purchasing. Conclusion: Although preliminary, the results suggest that multi-component interventions appear to be the most promising in terms of real changes to purchasing behavior. Important considerations include the significant heterogeneity in reported outcomes, and the notable lack of studies assessing for substitution effects. Policy makers, in their examination of these findings, should consider these limitations.
