13. 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

14. 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. Technological development of aqueous extracts from Calycophyllum spruceanum (Benth.) Hook. f. ex K. Schum., Rubiaceae, (mulateiro) using factorial design
The aim of the present work is to characterize the vegetal raw material of the Calycophyllum spruceanum (Benth.) Hook. f. ex K. Schum., Rubiaceae, known as "mulateiro", and to evaluate the influence of extractive parameters for attainment of standardized aqueous extractive solutions. The physical-chemical characterization of the samples was performed using p

17. Tannase production by Penicillium atramentosum KM under SSF and its applications in wine clarification and tea cream solubilization
Tannin acyl hydrolase commonly known as tannase is an industrially important enzyme having a wide range of applications, so there is always a scope for novel tannase with better characteristics. A newly isolated tannase-yielding fungal strain identified as Penicillium atramentosum KM was used for tannase production under solid-state fermentation (SSF) using

19. Phytochemical study and evaluation of the antimicrobial activity and cytotoxicity of Cuscuta racemosa
Cuscuta racemosa Mart. is a parasitic plant of the Convolvulaceae family, used in popular medicine as an anti-inflammatory and a diuretic, for stomach and hepatic disorders, and for treating fresh wounds. This plant is popularly known as "cipó-chumbo" and "fios-de-ovos". In this study, it was chemically investigated and tested for its antimicrobial activity

20. 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

21. Determination of the antimutagenicity of an aqueous extract of Rhizophora mangle L. (Rhizophoraceae), using in vivo and in vitro test systems
An aqueous extract of Rhizophora mangle L. bark is used as raw material in pottery making in the State of Espirito Santo, Brazil. This extract presents large quantities of tannins, compounds possessing antioxidant properties. Tannin antioxidant activity, as a plant chemical defense mechanism in the process of stabilizing free radicals, has been an incentive

22. PROPRIEDADES FÍSICO-MECÂNICAS E RESISTÊNCIA A BIODETERIORADORES DE CHAPAS AGLOMERADAS CONSTITUÍDAS POR DIFERENTES PROPORÇÕES DE MADEIRA E CASCA DE ARROZ / PHYSICAL-MECHANICAL PROPERTIES AND DECAY RESISTANCE OF WOOD AND RICE HUSK PARTICLEBOARD IN DIFFERENT PROPORTIONS
This work aimed at evaluating the quality of particleboards manufactured with different wood proportions (Eucalyptus grandis W. Hill. ex Maiden) and rice husk. The composites were produced in the proportions 0, 20, 40, 60, 80 and 100% of peels of rice with the use of urea-formaldehyde and tannin-formaldehyde adhesives. In order to characterize the quality of

24. 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
