AI Technical Summary
The prior art is difficult to effectively increase the content of γ-glutamine peptide in food, and the traditional screening method is time-consuming and costly, and cannot meet the needs of industrial production.
By providing a screening method for γ-glutamyl peptides, using γ-glutamyl transpeptidase for enzyme synthesis, combined with LC-MS/MS analysis, toxicity and water solubility analysis, and affinity analysis with 5K5S receptor proteins, γ-glutamyl peptides with better quality were screened out.
It has achieved more accurate and efficient screening to obtain better γ-glutamine peptides, which are simple to operate and have low cost, and can be synthesized by biological enzyme methods. It is suitable for improving the umami taste of food while reducing the amount of salt.
