Preparation of Compound Amino Acid from Leftovers of Embryo Cervi

Objective： To prepare compound amino acids from the leftovers of embryo cervi. Methods： Microwave - assisted acidolysis method was used to treat the leftovers of embryo cervi. Folin - phenol method, formol titration and Kjeldahl determination were respectively used to determine the protein content and hydroly- sis of amino acids. Automatic amino acid analyzer was used to analysize amino acid. Results： The leftovers of embryo cervi were acidolysised after microwave - disposed 30 min, compound amino acids were obtained, and the hydrolyzable degree was 8.27%. Compound amino acids included such 17 kinds of amino acids as gluta- mate, glycine, alanine, leucine, et al. Conclusion： High - quailty of compound amino acids could be not only obtained through utilization of the microwave - assisted acidolysis method with which treat the leftovers of embryo cervi, but also the cost of production was lowed, showing that this technology could be widely applied.
