Abstract
The present invention discloses a method for producing wheat glutamine peptide using wheat gluten powder as raw material, belonging to the fields of food and biotechnology. The method includes the steps of: performing enzymolysis in two steps using Alcalase and papain with the wheat gluten powder as raw material, to obtain the wheat glutamine peptide with components with molecular weight of less than 1000 Da being more than 90%, characteristic glutamine peptide segment glutamine-arginine-glutamine (Gln-Arg-Gln, QRQ) content being more than 2.0% and glutamine content being up to 23.54% by treating the enzymatic hydrolysate by centrifugation, ultrafiltration, concentration, spray drying, etc. The produced glutamine peptide can be used as functional nutrition composition ingredient in the development and production of ordinary foods, health foods and medicines.
