Nutritive value of soybean protein supplemented with purified amino acids and bread

The nutritive value of soybean alone, supplemented with methionine+tryptophan or with bread was investigated. The results showed high Net Protein Utilization (N.P.U.) values for the autoclaved soybean diet (61.5) compared with that of raw soybean supplemented with methionine+tryptophan (57.7). It was found that rats fed the diets of raw soybean supplemented with methionine and tryptophan survived and the growth was improved to some extent.
