O suco de laranja é um alimento rico em substâncias antioxidantes, como os flavonoides cítricos, vitamina C e carotenoides, que podem reduzir o estresse oxidativo que está relacionado à gênese das doenças cardiovasculares, diabetes e câncer. No entanto, o processamento da laranja para obtenção do suco interfere no tipo e quantidade dos compostos antioxidantes, podendo comprometer as ações esperadas. O objetivo deste trabalho foi avaliar a atividade antioxidante do suco de laranja, comparando os resultados após a ingestão aguda do suco de laranja fresco e do suco de laranja pasteurizado comercialmente em indivíduos adultos saudáveis. Cada voluntário foi submetido a dois tratamentos: ingestão aguda de suco de laranja fresco e, após intervalo de 30 dias, ingestão aguda de suco de laranja pasteurizado. Nos dois tratamentos foram colhidas amostras de sangue dos indivíduos antes e após a ingestão do suco de laranja. O efeito antioxidante total foi mensurado pelo ensaio do radical ABTS+ (2,2'azinobis (3-etilbenzenotiazolina 6-sulfônico) e pelo ensaio de TBARS (substâncias reativas ao ácido tiobarbitúrico) nas amostras de sangue. Observou-se um aumento de 2,2% na capacidade antioxidante do sangue a partir de 4 horas após a ingestão do suco de laranja fresco e que se manteve estável até 24 horas do consumo (p<0.05). Já com a ingestão do suco de laranja pasteurizado, a capacidade antioxidante se manteve estável e equivalente ao suco de laranja fresco nas primeiras 4 horas, mas aumentou 1,4% após 8 horas, permanecendo neste nível até as 24 horas seguintes (p<0.05). Após a ingestão do suco fresco, os níveis de peroxidação lipídica, diminuíram 27% nas primeiras 4 horas. Porém, a partir das 8 h retornaram ao valor inicial. Os resultados após o consumo do suco pasteurizado mostraram uma redução da peroxidação lipídica em 18% a partir das 4 horas e 8 h (p<0.05), e esta redução se acentuou (27%) às 24 h ...

The aim of the present study was to verify, through the response surface methodology, the optimum conditions for the combined use of aqueous extract of white lupine (Lupinus albus L.) and tropical pitanga juice (Eugenia unifl ora L.) in the development of a drink. Therefore, the independent variables were represented by the volume of aqueous extract of lupine (mL) and by the volume of pitanga juice (mL). The dependent variables (responses) were obtained through sensory test of acceptance (“appearance”, “aroma”, “taste” and “overall acceptability”). The combined optimization of the variables pointed the second formulation (50mL of aqueous extract of lupine and 30mL of pitanga juice) of the experimental project as the most adequate. In conclusion it was possible to get a drink with attractive sensory characteristics using aqueous extract of white lupine and tropical pitanga juice. The usage of response surface methodology made possible the determination of regions of maximum acceptance for each attribute evaluated in the formulation of a drink with aqueous extract of white lupine and pitanga juice, with a minimum of tests.

Infection with hepatitis C virus is a worldwide public health problem it affects about 170 to 250 million people worldwide may lead to complications such as cirrhosis and hepatocellular carcinoma. Patients with chronic hepatitis C most often is inadequate nutrient intake, macro and micronutrients, which induces changes in nutritional status and lipid profi le. Supplementation with vitamin C has shown benefi t. Limited information is available on levels of vitamin C in this type of illness. The study aimed to evaluate the effect of regular intake of orange juice on the nutritional and dietetic of patients with chronic hepatitis C infection. The study enrolled 23 patients volunteers, 13 men and 10 women treated at the Special Health Service of Araraquara (SESA). They consumed for 8 weeks 500 mL.d-1 of pasteurized orange juice. At baseline and after 8 weeks of juice intake the patients were evaluated for anthropometric parameters. The dietary intervention with 500 mL.d-1 with orange juice during the 8 weeks did not alter the nutritional status of patients.

Mulberry (Morus nigra L.) is a fruit with a great potential for technological uses, which could be employed to manufacture of syrups, ice cream, candies, yoghurts, beverages, jam, etc. Only the leaf from mulberry trees is commercially used for silkworm feeding. This tree is cultivated on many agricultural environments such as small rural proprieties and settlements. Small farmers waste a great amount of their production for not knowing about mulberry technology. Thus, the objective of this work was to access extraction yield and physical-chemical properties of mulberry whole juice from ripe, green and a mixture of both by using press and depulper. Statistical analysis of results was carried by media and standard deviation calculations. 173 kg of mulberry were picked being 49.31% ripe and 50.68% green. Press delivered greater extraction yield of whole juice (80.50% to 81.60%) when compared to press (71.43% to 77.50%). Whole juice obtained from both equipments has shown the following values: soluble solids 7.45% - 12.11%, titrable acidity 0.45 – 1.23%, ratio 6.03 – 26.84, pH 3.69 – 4.35, total reducing sugar 4.05% – 9.96%, reducing sugar 3.95% - 9.15%, sucrose 0.00% - 0.04%, turbidity 221.25 NTU - >4,000 NTU. Whole juices obtained from both equipments has shown similar physical-chemical characteristics except turbidity. The authors concluded that press was the best extraction equipment due to its greater yield and whole juice quality regarding turbidity
