What are the process conditions for enzymatic preparation in rice proteolytic peptides?

① How are rice proteolytic peptides extracted?

Enzymatic extraction of rice protein peptides is a light yellow powder product that uses high-quality rice protein as raw material and is refined through modern biological enzyme engineering technology such as compound enzyme gradient enzyme digestion technology. The principle of enzymatic hydrolysis is to use protease preparation to degrade and modify rice protein, turning it into soluble peptides and extracting them.

②What are the process conditions that affect the preparation of rice proteolytic peptides?

In the process of proteolysis of rice, commonly used enzyme preparations include neutral protease, alkaline protease, complex protease and flavor enzyme, etc. However, different enzyme preparations will have different effects on rice protease due to factors such as enzymatic hydrolysis temperature, enzymatic hydrolysis time and enzyme amount. The antioxidant activity of the decomposed products will be affected, so the content of small molecule peptides or amino acids obtained will be different. A large amount of research data has confirmed that rice proteolytic peptides were prepared by hydrolyzing rice protein with protease, and comparing the process curves of hydrolyzing rice protein, it was concluded that the hydrolysis effects of different proteases are different. The main process conditions to be considered are: substrate concentration, pH value, enzymatic hydrolysis temperature, enzymatic hydrolysis time, addition amount, etc., taking alkaline protease as an example, under the corresponding process conditions, the yield of rice peptide is 46.8%, and the purity is 71.3%.

③ Advantages of enzyme preparations in rice proteolytic peptides

Enzyme preparations are used in rice protein peptides. Due to the mild enzyme extraction reaction conditions, the protein polypeptide chain can be hydrolyzed into short peptide chains, which improves the solubility of the protein and the solid content in the extract, creating favorable conditions for industrial production. Secondly, the rice proteolytic peptides produced by enzyme preparations have extremely strong biological activity and diversity. In today's nutritional food industry, it has become a high-end functional food with high quality, high technical content and broad market prospects. It can be widely used in special medical food, healthy nutritional food and health food.
