Embodiment Construction
[0025] Provided is an environment-improving agent mainly composed of rice protein peptides, which is added to conventional diets at a weight percentage of 1.5-3%.
[0026] 1. The production process of rice protein peptide: (1) Put 8~10% rice protein suspension solution in the enzyme reactor, heat to 50°C, adjust the pH to 8.0 with 1 mol / L sodium hydroxide, and then press The ratio of enzyme to protein is 1% (percentage by weight) and alkaline protease is added. During the reaction, 1 mol / L sodium hydroxide solution is added dropwise to maintain the stability of pH. After 2.5-3 hours of reaction, add 1 mol / L HCl to adjust the pH to 7. After 0, hydrolyze with 0.3-0.5% (weight percent) trypsin for 1.5-2 hours, heat the reaction solution to boiling and keep it for 5-10 minutes to inactivate the enzyme, cool to 25-30°C, and centrifuge at 2000 rpm for 10 minutes , and the supernatant was spray-dried to obtain the rice protein peptide.
