13. Características nutricionais e fatores antinutricionais na fermentação ruminal in vitro de espécies arbóreo-arbustivas nativas e exóticas em área de Caatinga no Sertão de Pernambuco / Nutritional characteristics and antinutricional factors in in vitro rumen fermentation assay of native and exotic arboreal species from savanna area in Pernambuco
A vegetação nativa do sertão nordestino é rica em espécies forrageiras nos estratos herbáceo, arbustivo e arbóreo. Estudos têm revelado que acima de 70% das espécies botânicas da caatinga participam significativamente da composição da dieta dos ruminantes domésticos. Estrategicamente, as espécies lenhosas são fundamentais no contexto de produ�

14. Caracterização nutricional e antinutricional de folhas de Abelmoschus esculentus (L.) Moench; atividade microbiológica da lectina presente na fração 30%
The non-conventional vegetabless leafy such as seeds, stems, leaves and crumbs, can be inserted in food as an alternative source of nutrients. Among the alternatives, there is okras leaves (Abelmoschus esculentus), vegetable belonging to the Malvaceae family, is widespread in tropical regions. However, the bioavailability of nutrients can be affected by anti

15. Relationship between color and tannin content in sorghum grain: application of image analysis and artificial neural network
The relationship between sorghum grain color and tannin content was reported in several references. In this study, 33 phenotypes of sorghum grain differing in seed characteristics were collected and analyzed by Folin-Ciocalteu method. A computer image analysis method was used to determine the color characteristics of all 33 sorghum phenotypes. Two methods of

16. Pentaclethra macroloba tannins fractions active against methicillin-resistant staphylococcal and Gram-negative strains showing selective toxicity
The ethanol extract of the vegetal species Pentaclethra macroloba (Willd.) Kuntze, Fabaceae, was fractioned and the antibacterial activity was determined. The active ethyl acetate (ea) fraction showed activity against Gram-positive (Staphylococcus spp. and Enterococcus spp.) and Gram-negative (Pseudomonas aeruginosa, Acinetobacter spp. and Klebsiella pneumon

17. Feijão pré-cozido irradiado com raios gama do Cobalto-60: uma alternativa de consumo / Precooked beans irradiated with gamma rays of Cobalt-60: an alternative for consumption
The bean (Phaseolus vulgaris L.) is a leguminosae with high nutritional value due especially to its mineral and proteinic content. A decrease in consumption of beans has been observed due to modern eating habits related to factors such as distance between home and work, increase in the number of female workers outside home, labor market competition which acc

18. Determinação dos mecanismos de ação envolvidos nas atividade antiulcerogenica e antioxidantes de Rhizophora mangle L / Determination of the mechanisms of action in the antiulcerogenic and antioxidant activities of Rhizophora mangle L
The pharmacological research has been focusing on the folk medicine knowledge in order to establish the scientific basis of their pharmacological effects. Nowadays, tannins play a prominent role because of its high antioxidant capacity and, due to the progress made in the analysis and identification of these compounds and their therapeutic possibilities.

19. Atividade Anti-helmíntica de Cocos nucifera L. Sobre Nematóides Gastrintestinais de Ovinos / Anthelmintic activity of Cocos nucifera L. on Gastrointestinal Nematodes of Sheep
The gastrointestinal nematodes control of small ruminants has been realized by synthetic anthelmintics. However, the development of resistance required research of control alternatives. Among these alternatives is the use of medicinal plants rich in condensed tannins. The objective of this work was to evaluate the efficacy of Cocos nucifera fruit against gas

20. Use of raw material obtained from a renewable source in tbhe preparation of phenolic type matrix composites / Utilização de matéria-prima obtida de fonte renovável na preparação de compósitos de matriz tipo fenólica
In the present work phenolic type matrices were prepered, which were reinforced with lignocellullosic fibers (sisal). The tannin-phenolic and phenol-furfural resins, amid other techniques, were characterized by nuclear magnetic resonance (NMR). Model compounds were synthesized specially for the 1H and 13C NMR analysis of phenol-furfural resins. The sisal fib

21. Características físico-químicas, nutricionais e sensoriais de pão de forma com adição de grãos de linhaça (Linum usitatissimum) / Physico-chemical, nutritional and sensory characteristics of flax seed wheat bread (Linum usitatissimum)
Food industries offer to consumer several types of breads options which vary from whole wheat to enrich with multigrain such with flax seed. Flax seed is considered a functional food that has important content of omega 3 fat acids, soluble fiber and protein, however it intakes is very low in our diet. The aim of the research was to prepare a wheat bread enri

22. Avaliação in vitro de leguminosas taniníferas tropicais para mitigação de metano entérico / In vitro evaluation of the taninniferous tropical legumes in order to mitigate enteric methane
Animals contribute to increasing the methane concentration in the atmosphere through the fermentation of livestock manure and the fermentation in the digestive tract, e.g, enteric fermentation. The enteric fermentation of ruminants, pseudoruminants (horses, donkeys, mules) and non-ruminants produce an average of 80 Tg/year of methane and comprise 28 % of glo
