AI Technical Summary
In the prior art, when preparing antioxidant peptides and anti-fatigue peptides, there are problems of high cost and many by-products, especially when using cost-effective protease enzymatic method, the process conditions are complex and the product complexity is high.
Fresh pigeon breast meat was used as raw material, and pigeon meat antioxidant peptide was prepared by enzymatic method, and the pigeon meat anti-fatigue peptide was isolated and purified by ultrafiltration. The method includes enzymatic decomposition of pigeon meat with neutral and alkaline protease complexes, and subsequently obtaining antioxidant peptides by centrifugation and lyophilization, and isolation of anti-fatigue peptides through ultrafiltration membranes.
The prepared pigeon meat antioxidant peptide and anti-fatigue peptide have significant antioxidant activity and anti-fatigue effect, and the molecular weight is less than 5000 Da, which is easy to be absorbed by the human body, significantly improving SOD enzyme activity.
