Abstract:The antioxidant effect of adding peptides of different origins (pea, corn, milk whey and wheat germ and
bone proteins) on sausages during 7 days of storage at 4 ℃ was evaluated in this study. The pH, a *, TBARS and sensory
characteristics of sausages were measured. The results showed that lipid oxidation was significantly lower in sausages with
added peptides than control samples (no added peptides). Corn peptides had stronger antioxidant effect on sausages than
peptides of other origins. Milk whey peptides could not only inhibit the occurrence of oxidation, but also improve the texture
of sausages. Wheat germ peptides had a certain effect on the redness value of sausages.
