13. Effect of freezing and processing technologies on the antioxidant capacity of fruit pulp and jelly
The effect of freezing and processing technology on the antioxidant capacity of grape (Vitis vinifera), apple (Malus domestica), strawberry (Fragaria x Anassa), pear (Pyrus communis L.), guava (Psidium guajava L.), and fig (Ficus carica L.) was evaluated for 90 days. Under a storage temperature of -15 º C, there was no significant difference in the antioxid

14. Composição química e propriedades funcionais no processamento de vinagres / Chemical composition and functional properties in the processing fo vinegar
The fruit vinegars increasingly become popular on the planet, being produced from various crops or their residues, using classical and modern techniques. These products have great variety of organic acids, vitamins, minerals, phenolic compounds and other elements with important physiological functions. Vinegar higher quality depends more on their secondary c

15. Production of functional killer protein in batch cultures upon a shift from aerobic to anaerobic conditions
The aim of this work was to study the production of functional protein in yeast culture. The cells of Saccharomyces cerevisiae Embrapa 1B (K+R+) killed a strain of Saccharomyces cerevisiae Embrapa 26B (K-R-)in grape must and YEPD media. The lethal effect of toxin-containing supernatant and the effect of aeration upon functional killer production and the corr

17. Extrato de bagaço de uva como antioxidante natural em carne de frango processada e armazenada sob congelamento / Grape pomace extract as natural antioxidant in processed chicken meat stored under freezing
Chicken meat, due to the high concentration of unsaturated fatty acids, is highly susceptible to lipid oxidation, which affects taste, aroma, colour and texture of foods, limiting its stability and shelf-life. Due to the possible toxicity of synthetic antioxidants and the current demand for healthier products, the use of natural antioxidants, such as grape s

18. Development of blend composed by fruits and vegetable to improve the nutritional and functional quality / Desenvolvimento de suco misto de frutas e hortaliça para melhoria da qualidade nutricional e funcional
The appeal around foods natural and healthy is one of the causes of the increased consumption of fruit juice in Brazil. On supermarket shelves are available mix juices (blends) with two or more fruits, products developed to improve the nutritional quality and to create a new flavor. This work aimed the development of a bend with two fruits and a vegetable. T

19. Avaliação da atividade antioxidante, antiinflamatória e analgésica de sementes de resíduos de vinificação
The worldwide wine production is around 149 millions of hectoliters per year which generate around 13% by weight of the grapes processed as wastes, which are generally used as fertilizer or simply discarded. These residues are sources of phenolic compounds that contribute to the prevention of several diseases, including cancer, atherosclerosis and neurodegen

20. Utilização das águas da fermentação do polvilho azedo na elaboração de uma nova bebida
Cassava starch sour wastewater is an effluent from cassava starch fermentation process. Fermentation wastewater was studied to a non alcoholic refreshing new beverage production, originally named #Frëshpa#. The principal barrier is mask the cassava starch sour characteristic flavor, conferred by lactic, propionic, butyric acids and other volatile compounds

21. Grape juice and norbixin : in vitro in vivo antioxidant activity / Atividade antioxidante in vitro e in vivo de suco de uva e da norbixina
Epidemiological studies shown that the consumption of diets rich in plant foods and beverages is associated with reduction in the development of chronic-degenerative diseases. These foods are sources of substances such as carotenoids and polyphenols that can act as chemoprotectives agents, reducing the damage caused by reactive oxygen species, formed both in

22. Métodos de amostragem e tamanho de amostra para avaliar o estado de maturação da uva Niágara Rosada / Sampling methods and sample size to evaluate the maturation state of the Ni´agara Rosada grape
Sao Paulo state is the main table grape producer in Brazil, being the Niágara Rosada (Vitis Labrusca) the predominant cultivar. To offer quality products to the market, the producers need to determine, periodically, the grapes maturation state, being the content of soluble solids the main variable measured. To determine this content, a sample of fruits in a

23. SUBPRODUTOS DA UVA PARA UTILIZAÇÃO EM DIETAS DE FRANGO DE CORTE
O objetivo deste trabalho foi determinar in vitro a composição centesimal, a atividade antibacteriana, antioxidante e tanante de subprodutos da uva (Vitis vinifera) para seu aproveitamento na indústria avícola. O conteúdo de fibra bruta do bagaço foi de 31,6% e de lignina das sementes foi de 61,2%. As sementes prensadas renderam 13,4% de óleo bruto, c

24. Specific amplification of iron receptor genes in Xylella fastidiosa strains from different hosts
Bacterial production of siderophores may involve specific genes related to nonribosomal peptide and polyketide biosynthesis, which have not been fully identified in the genome of Xylella fastidiosa strain 9a5c. However, a search for siderophore-related genes in strain 9a5c indicated five membrane receptors, including siderophore, ferrichrome-iron and hemin r
