, , LAIR CHAVES CABRAL 4 e JOÃO TOMAZ DA SILVA BORGES 5 RESUMO -O presente trabalho teve por objetivo caracterizar quimicamente os extratos hidrossolúveis desidratados de arroz (Oryza sativa L.) e de soja (Glycine max (L.) Merrill). Os processos utilizados para a obtenção dos extratos hidrossolúveis foram: maceração do arroz e da soja, desintegração, centrifugação, adição de ácido cítrico, fervura e secagem por atomização. A caracterização química foi realizada através das seguintes determinações: composição centesimal aproximada, composição de minerais e atividade do inibidor de tripsina. Com o aumento das proporções de soja (0 a 50%), os extratos hidrossolúveis desidratados tiveram aumento nos teores de proteína, extrato etéreo, cinzas e fibra crua, porém diminuição no teor de carboidratos. Os teores de P, K, Mg, Cu e Co foram altos em alguns extratos hidrossolúveis desidratados estudados, os quais foram semelhantes à indicação diária na Recommended Dietary Allowances, enquanto os demais minerais se mostraram em pequenas quantidades ou apenas traços. Não foi detectada atividade do inibidor de tripsina.Termos para indexação: Glycine max, Oryza sativa, composição centesimal, composição de minerais. CHEMICAL CHARACTERIZATION OF DEHYDRATED RICE AND SOYBEAN WATER-SOLUBLE EXTRACTSABSTRACT -The objective of the present study was to evaluate the chemical characteristics of dehydrated water-soluble extracts of rice (Oryza sativa L.) and soybean (Glycine max (L.) Merrill). The preparation included soaking of the rice and soybean, desintegration, centrifugation, addition of citric acid, boiling and spray drying. Dehydrated water-soluble extracts were analysed for their proximate composition, minerals content and trypsin inhibitor activity. Results indicated that an increase in the proportion of soybean (0 to 50%) resulted in an increase in the content of proteins, oil, ash, crude fiber, as well as a decrease in the percentage of carbohydrates. The content of P, K, Mg, Cu and Co in some of the extracts were particularly high and were comparable with those of the Recommended Dietary Allowances. Other minerals were detected in low or trace amounts. No trypsin inhibitor activity was detected.

We investigated the enzymatic complex produced by selected fungi strains isolated from the environment using the agro-industrial residues rice husk, soybean hull, and spent malt as substrates. Microbial growth was carried out in solid-state cultivation (SSC) and in submerged cultivations (SC) and the enzymatic activities of xylanase, cellulase, β-xylosidase, and β-glucosidase were determined. All substrates were effective in inducing enzymatic activities, with one strain of Aspergillus brasiliensis BLf1 showing maximum activities for all enzymes, except for cellulases. Using this fungus, the enzymatic activities of xylanase, cellulase, and β-glucosidase were generally higher in SSC compared to SC, producing maxima activities of 120.5, 25.3 and 47.4 U g of dry substrate, respectively. β-xylosidase activity of 28.1 U g of dry substrate was highest in SC. Experimental design was carried out to optimize xylanase activity by A. brasiliensis BLf1 in SSC using rice husk as substrate, producing maximum xylanase activity 183.5 U g dry substrate, and xylooligosaccharides were produced and characterized. These results suggest A. brasiliensis BLf1 can be used to produce important lytic enzymes to be applied in the preparation of xylooligosaccharides.
