Abstract

Weanling male albino rats were given test diets containing high-protein raw or cooked biscuit mixes as protein source. After 1 wk on the diets, the concn. of free lysine, methionine, threonine and tryptophan in the blood plasma was determined microbiologically. Plasma lysine levels were significantly lower in rats fed the cooked biscuits (8.3 and 9.4 mu g/ml) compared with those fed the unbaked ingredients (26.8 and 28.5 mu g/ml) or dried skim-milk (85.3 mu g/ml). Threonine levels were much higher and methionine and tryptophan levels slightly higher in the plasma of rats fed the cooked biscuit mixes compared with those fed uncooked mixes. This is thought to be a result of the reduced availability of the lysine. Examination of plasma amino acid scores confirmed that lysine was the most limiting amino acid in the cooked biscuits, while lysine, threonine and methionine were co-limiting in the uncooked mix.
