O Brasil é reconhecido mundialmente como o maior produtor e exportador de suco de laranja do mundo. O líquor de laranja é um dos principais subprodutos da indústria cítrica, rico em açúcares e destinado, quase que exclusivamente para a produção de ração animal, já que seu descarte certamente causaria problemas ambientais. Com o intuito de ter um melhor aproveitamento deste subproduto, foi desenvolvido um novo tipo de destilado obtido a partir da fermentação do líquor de laranja. Dado o enorme volume de líquor e considerando-se também o enorme volume de fermento de descarte da indústria cervejeira (160 milhões de litros/ano) ainda viável, está sendo objeto de estudo a utilização deste fermento na obtenção da aguardente de líquor de laranja. Nesse sentido, foram obtidas amostras de aguardente de líquor de laranja, utilizando-se de técnicas tradicionais de produção de cachaça, sendo o líquor fermentado de fermento que é descarte da indústria cervejeira. Dessa forma, foram avaliados a viabilidade da levedura de descarte da indústria cervejeira, o teor de sólidos solúveis, o teor de cobre e carbamato de etila na aguardente de líquor de laranja obtida utilizando alambique de aço inoxidável.

The global energy scenario is currently a widely discussed topic, with growing concern about the future supplies. Thus, much attention has been dedicated to the utilization of biomass as an energy resource. In this respect, orange peel has become a material of great interest, especially to Brazil, which generates around 9.5 million tons of this waste per year. To this end, the authors studied the kinetics of the thermal processing of dried orange peel in inert and oxidizing atmosphere. The thermodynamic parameters were determined by the Ozawa-Flynn-Wall method for the global process observed during heating from the 25 degrees C up to 800 degrees C. The thermal analysis in air and nitrogen showed 3-2 stages of mass loss, respectively, with approximately 20% residual mass under a nitrogen atmosphere. The increase in the values of activation energy for the conversion points between 20% and 60% for thermal effects in air and nitrogen atmosphere was observed. The activation energy obtained in an oxidizing atmosphere was higher than that obtained under a nitrogen atmosphere. The fourier-transform infrared spectroscopy and X-ray diffraction analysis showed that the material has a high level of complexity with the presence of alkali and alkaline earth groups as well as phosphate, plus substances such as pectin, cellulose and lignin.

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.

The aim of this paper was to measure the total soluble solids content (°Brix), titrable total acidity (AT) and ratio in orange beverages, such as frozen concentrated juice, not from concentrate juice, nectar and soft drink and to compare them with their Quality and Identity Standards (PIQ) published by the Ministry of Agriculture, Livestock and Food Supply (MAPA) and Codex Alimentarius. Four orange frozen concentrated juices, twenty two juices, seven nectars and thirteen orange soft drinks were analyzed. All frozen concentrated orange juices were in agreement with Codex Alimentarius. The majority of not from concentrated orange juices and soft drinks was in accord to Brazilian legislation. The orange nectars could not be compared with the standards because they are not published by MAPA or Codex Alimentarius.
