Evaluation of dietary protein quality
1978
Uribe-Peralta, Alejandro
Abstract: The use of a target protein against which the quality of other dietary proteins could be compared has been examined in rats. Milk, the natural food during the early life of mammals, was proposed as the target standard. The milk standard diet was compared with proteins of different origins, amino acid pattern, or lacking an essential amino acid. A chemical score based on rat's milk (CSM-R) was developed to evaluate the quality of the protein diets; it combined determination of a protein's most limiting amino acid with a capacity for ranking proteins by nutritional values. Diets were evaluated for protein efficiency ration, body weight gain, levels of amino acids and protein complementation. Results indicated that rat milk contains a proportion of amino acids which provides maximum protein utilization in growing rats, and may also protect the lactating mother. Other diets were usually inferior. The CSM-R score appeared to be a useful analytic tool in evaluating the quality of dietary proteins.
