Abstract

Tempeh is a traditional fermented soybean product prepared by fermenting cooked dehulled soybean with Rhizopus oligosporus. In the present study tempeh prepared from (i) a mixture of groundnut and soybean (1:1 dry wt. basis) was compared with (ii) soybean tempeh with regard to the following effect of supplementation with limiting amino acids, methionine (Met), lysine (Lys) and tryptophan (Trp); supplementary value with rice diets to rats; and intestinal gas forming properties. Protein quality of (i) 40.0% and (ii) 35.7% was good. Net protein utilization (NPU) was not improved by addition of limiting amino acids: (ii) + Met 66 plus/minus 4.1, (i) + Met 68 plus/minus 3.4, (ii) + Met, Lys, Trp 64 plus/minus 4.3, (i) + Met, Lys, Trp, 62 plus/minus 2.0. Net dietary protein cal % of the diets was improved by addition of Met (values for (ii) alone, + Met, and + Met, Lys, Trp being 6.56 plus/minus 0.315, 6.81 plus/minus 0.424, and 7.23 plus/minus 0.48, resp., corresponding values for (i) being 7.11 plus/minus 0.373, 7.62 plus/minus 0.548, and 6.78 plus/minus 0.274). Supplementation of rice diets at 10% protein level (which was 18% for intestinal gas formation studies), gave good supplementary values (NPU being (i) 61 + 2.2 (ii) 60 plus/minus 3.89 vs. 72 plus/minus 4.69 for skim milk diet). Total vol. of gas formation in 4 h after ingestion of diet with (i) and (ii) were 4.00 plus/minus 0.790 ml and 4.05 plus/minus 0.802, resp. vs. 1.05 plus/minus 0.210 ml for casein diet.
