The invention discloses a dandelion seed antioxidant tetrapeptide and a preparation method. The sequence of the antioxidant tetrapeptide is Trp-Thr-Leu-Asn (WTLN). In vitro experiments show that this peptide can effectively scavenge free radicals such as DPPH, ABTS, hydroxyl radicals and superoxide anions, and at the same time it has the effect on peroxidation of linoleic acid. inhibition. The antioxidant tetrapeptide involved in the present invention has the characteristics of simple structure, strong antioxidant activity, etc., can be used as an excellent substitute for existing artificially synthesized antioxidants, and has important value in the development and application of new food additives. |
