In order to demonstrate whether the known biological effects ofAloe vera(L.) Burm. fil. could correlate with the antioxidant activity of the plant, the antioxidant activity of the aqueous leaf extract was investigated. The present study demonstrated that the aqueous extract fromA. veraleaves contained naturally occuring antioxidant components, including total phenols, flavonoids, ascorbic acid, β-carotene and α-tocopherol. The extract exhibited inhibitory capacity against Fe3+/ascorbic acid induced phosphatidylcholine liposome oxidation, scavenged stable DPPH•, ABTS•+and superoxide anion radicals, and acted as reductant. In contrast, the leaf inner gel did not show any antioxidant activity. It was concluded that the known beneficial effects ofAloe veracould be attributed to its antioxidant activity and could be related to the presence of phenolic compounds and antioxidant vitamins.

Demand for minimally processed fruits have increased due to their nutritional value and an increasing change in consumption habits. Physicochemical, microbiological, structural and sensory changes were determined in minimally processed mangoes (MPM) with chitosan (CH) edible coatings and lemon and orange essential oils (EOL). The MPM was first dipped in citric acid and a texturizing solution and then dipped in CH and lemon or orange EOL coatings. Weight loss, sensory acceptance, total soluble solids, total acidity, ascorbic acid, color changes, firmness and elasticity, and microbiological changes were quantified for 11 days of refrigerated storage. The CH and lemon EOL coating had more acceptance than the other treatments. No differences were found (p>0.05) for weight loss, total acidity, ascorbic acid, firmness or elasticity. There was a high amount of total phenols due to the EOL composition, as well as a high antioxidant capacity in the early days of storage. This characteristic decreased in the final days of the study. There was a decrease in the microbial charge for the lemon EOL treatment, as compared to the other samples. The CH and lemon EOL coating helped to maintain the shelf-life of the MPM for 11 days of storage without affecting the sensory acceptance. The CH and Orange EOL coating did not have an effect on the MPM physicochemical attributes; however, the sensory acceptance was negatively affected with off-flavors conferred to the MPM.

Present study was directed to analyze and compare the bioactive compounds (total phenols, total anthocyanins), vitamins (ascorbic acid, β-carotene, vitamin A), minerals including Ca, Mg, Na, P, K, Fe, Cu, Zn, Co, Mn and heavy metals (Cd, Hg, Pb) of freeze-dried (lyophilized) phalsa pulp and seed powder. In lyophilized pulp powder (LPP) higher amount of total phenols (78.11 mg/100g), total anthocyanin (82.94 mg/100g), ascorbic acid (5.21 mg/100g), β-carotene (0.54 µg/100g), vitamin A (0.89 I.U.) were observed than lyophilized seed powder (LSP). Na, K, Mg and Co (0.41, 0.39, 1.08, 0.46 mg/100g, respectively) were higher in LPP as compared to LSP (0.29, 0.11, 0.76 and 0.40 mg/100g, respectively) whereas, Ca, P and Cu were detected more in LSP. This study opens the prospect of using dry phalsa powder in the preparation of various nutraceutical and functional foods for their therapeutic as well as prophylactic purposes.

Vegetable, due to higher neutraceutical component, are termed as protective food against various major and minor diseases. Scientific agro-techniques under optimum growing condition like temperature, relative humidity and light intensity, positively influence the qualitative and quantitative attributes of most of the vegetable crops including cherry tomato. It is one of potential vegetable crop, which is extensively utilized for table purpose and for preparing recipies in five star restaurants. Cherry tomato fetches higher prices in market due to good taste and higher nutrients, thus making qualitative attributes as an important factor to give higher returns to the farmers. Thus, this experiment was conducted to estimate the qualitative attributes in eighteen genotypes of cherry tomato grown under both open field and polyhouse conditions. The result of the study revealed that under open field condition, BRCT-30 was the best genotype with maximum value for lycopene content (6.62 mg 100-1 g FW) and β-carotene (2.30 mg 100-1 g FW), second maximum value for total soluble solids (7.85°Brix), third maximum value for reducing sugar and fourth highest position for ascorbic acid content (43.65 mg/100 g FW). Under polyhouse condition, the best genotype for quality parameters was BRCT-36 with maximum total soluble solids (10.81°Brix), lycopene (7.48 mg 100-1 g FW) and β-carotene (2.49 mg 100-1g FW) along with average range of values for ascorbic acid (72.36 mg 100-1 g FW) and titrable acidity (0.55 mg 100-1 g FW).

<p>Este trabalho teve como objetivo avaliar os parâmetros físico-químicos de polpas de fruta produzidas e comercializadas na cidade de Petrolina-PE, tendo como referência a Instrução Normativa nº 1, de 7 jan. 2000, do Ministério da Agricultura que define as características físicas e químicas estabelecendo limites mínimos e máximos específicos para cada polpa de fruta. Foram avaliadas duas marcas (1 e 2) de polpas de abacaxi, cacau, caju, graviola, maracujá e umbu, analisadas quanto aos parâmetros de pH, sólidos solúveis totais (SST), acidez total titulável (ATT), ácido ascórbico, relação SST/ATT e sólidos totais. Os resultados permitem inferir que a marca 2 apresentou qualidade superior na maioria dos parâmetros avaliados quando comparado com a marca 1. Entretanto para alguns sabores de polpa as duas marcas não atenderam os valores padrões. Entre as polpas o único sabor que apresentou os padrões exigidos foi a polpa de caju em ambas as marcas, e a que apresentou resultado de pior qualidade diante dos padrões foi a polpa de maracujá principalmente da marca 1. Dessa forma constata-se que há grandes variações entre as marcas, e entre alguns parâmetros, o que compromete a qualidade das polpas, prejudicando assim o consumidor.</p><p align="center"><strong><em>Physicochemical parameters of fruit pulps produced in Petrolina – PE</em></strong></p><p><strong>Abstract</strong><strong>: </strong>This study aimed to evaluate the physicochemical parameters of fruit pulps produced and marketed in the city of Petrolina-PE, with reference to the Instruction Nº 1 of 7 January 2000 of the Ministry of Agriculture, which defines the physical and chemical characteristics setting minimum and maximum limits specific to each fruit pulp. We evaluated two brands (1 and 2) of pineapple, cocoa, cashew, soursop, passion and umbu fruit pulp, analyzed for pH, total soluble solids (TSS), total titratable acidity (TTA), ascorbic acid, TSS / TTA and total solids parameters. Results show that the brand 2 showed superior in most evaluated parameters when compared to the brand 1. However, for some pulp flavors of both brands did not reached the standards values. Among the pulps, the only flavor that presented the required standards was the cashew pulp in both brands, and presented the results of lower quality on the standards was the passion fruit pulp mainly brand 1. Thus, it appears that there are great variations between brands and between some parameters, which compromises the quality of the pulp, thus impairing the consumer.</p>

Indigenous mango (Mangifera indica L.) varieties have unique aroma, taste, flavour, texture and size. The interactions among volatile compounds and with sugars and acids have a role in the distinct mango flavor. Murshidabad district of West Bengal has several indigenous mango varieties that have unique attributes like taste and aroma. The indigenous Champa mango variety of Murshidabad district has a distinct aroma very similar to that of the champaka flower (Michelia champaca L.). The present investigation was to determine if there was any phyto-chemical which could be responsible for the distinct and unique aroma present in the mango variety Champa. Eugenol, a phytogenic bioactive component frequently found in diversified herbal plants was found by GC-MS analysis of the methanolic extract of the fruit pulp of indigenous mango variety, Champa.
