摘要：
Effect of gamma irradiation on the content of methionine and tryptophan in soya protein products were investigated. Irradiation with doses of 1, 3 and 5 kGy caused significant (p = 0.05) decrease of methionine contents. Parallel with the decrease in methionine also the relative quality of proteins. is lowered. Tryptophan content were significantly reduced (p = 0.05) at irradiation doses of 3 and 5 kGy. The relative decrease of methionine and tryptophan contents are significantly correlated (p = 0.05) with relative increase in amount of products by the irradiation induced oxydation of lipids; correlation coefficients were 0.576 and 0.715.
