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.
