COMPARISON OF NUTRITIONAL QUALITY BETWEEN ENRICHED SOYBEAN HYDROLYTIC PROTEIN AND ENRICHED ENZYMOLYSIS PROTEIN / 第二军医大学学报

ABSTRACT

This paper compares nutritional quality between enriched soybean hydrolytic protein and enriched enzymolysis protein by mean of chemical and biological methods.It was found that the essential amino acids composition of enriched soybean hydrolytic protein was similar to those of enriched enzymolysis protein and casein and closer to the FAO/WHO pattern of amino acid requirements.Its amino acid score (AAS), true protein digestibility (TD), biological value (BV) and net protein utilization (NPU) were 97, 96.2?1.0, 77.1?1.4 and 74.2?0.9, respectively.These values were significantly higher than those of enriched enzymolysis protein and casein except for its TD.The results indicate that the enriched soybean hydrolytic protein has higher nutritional quality.
