[The efficacy of enriching wheat bread with lysine and its effect on gastric secretory activity].

A high biological effectiveness of bread enriched with microbiologically synthesized lysine has been proved in experiments on rats which were fed with this bread. Optimum lysine concentration for bread enrichment has been determined. The biological value of bread proteins with respect to all growth parameters increased proportionally, within the range of lysine concentration from 0.2 to 0.7%. Further concentration increase induced amino acid imbalance. Certain characteristics of the effect of lysine-enriched bread on the digestive organs were revealed in experiments on dogs. Intensified secretion of gastric juice, pepsin and hydrochloric acid was recorded under the effect of lysine-enriched bread. The data obtained have evidenced the possibility and effectiveness of bread enrichment with lysine.
