This experiment was undertaken to investigate the supplemental effects of limiting amino acids to unsteam-heated soy protein isolate in growing rats. The nutritive values of the protein and serum components as related to the protein and lipid metabolism were measured in the animals fed the soy protein isolate additionally supplemented with methionine, threonine, lysine and all the other essential amino acids successively. These measurements were also conducted in the animals fed whole egg protein and casein for reference. Results were as follows. The limiting amino acids of unsteam-heated soy protein isolate were mostly represented by sulfur-containing amino acids and threonine as well as those of the steam-heated one. For example, methionine and threonine supplements to unsteam-heated soy protein isolate improved the body weight gain, protein efficiency ratio (PER) and biological value almost up to their maximum values, i.e. 6.3g/day, 4.0 and 99, respectively. True digestibility of the sample, i.e. 97%, was found to be extremely high. The values of serum albumin, A/G ratio, urea nitrogen, HDL cholesterol and its proportion to total cholesterol in the methionine and threonine supplemented soy protein group were improved almost up or down to the levels of the whole egg protein group. These results indicated that the nutritive value of soy protein isolate and its metabolic effect for serum cholesterol are highly appreciated when its limiting amino acids are supplied by other food proteins.
