The invention relates to
dioscorea opposita
peptide polysaccharide composite
nutrient solution prepared by comprehensive development and utilization of
dioscorea opposita through biological
enzyme engineering. The optimal
process conditions of step enzymolysis of composite
enzyme comprises the following steps of: 1)first step of enzymolysis technology condition, namely, the rate of
solid to liquid is 1: (10-15), the
enzyme addition quantity accounts for 0.1 to 0.2 percent of total amount, the enzymolysis temperature is between 65 and 75 DEG C, a pH value is 6.0 to 7.0, and time is 1 to 2 hours; 2) second step of enzymolysis technology, the enzyme addition quantity accounts for 0.1 to 0.5 percent of total pulp quantity, the enzymolysis temperature is between 50 and 60 DEG C, the pH value is 6.0 to 7.0, and the time is 3 to 4 hours. The
dioscorea opposita is comprehensively developed and utilized by a biological enzyme
engineering technology to prepare dioscorea opposita
peptide polysaccharide composite
nutrient solution, and the comprehensive
utilization rate of the dioscorea opposita and
active ingredient extraction are greatly improved; the developed dioscorea opposita
peptide composite
nutrient solution is rich in nutritive ingredients such as peptide,
polysaccharide,
amino acid and the like, and is comprehensive and rich in
nutrition; by the process to prepare the dioscorea opposita peptide polysaccharide composite
nutrient solution, the process has the characteristics of reasonable and simple production technology and easiness in industrial production; and the prepared dioscorea opposita peptide polysaccharide composite
nutrient solution can be widely applied to various health-care food and health-care
medicine.
