ABSTRACT
The effects of rutin, quercetin, and caffeic acid on protein oxidation in Cantonese sausage during 60 days of storage at room temperature (25 ± 1 °C) were investigated. The results showed that the three phenolic compounds played different roles in inhibiting the oxidation of sarcoplasmic and myofibrillar protein. All of them inhibited sarcoplasmic protein oxidation by retarding carbonylation, the conversion of SH to S-S groups, and the formation of dimeric tyrosine and Schiff bases, of which rutin is the most effective. For myofibrillar protein, all of them suppressed the conversion of SH to S-S groups, only caffeic acid inhibited the accumulation of Schiff bases instead of carbonyls while both quercetin and caffeic acid inhibited the formation of dimeric tyrosine. In addition, quercetin had an inverse dosage effect on the oxidation regulation of MP, 0.16 g/kg quercetin had better inhibit effect on protein oxidation than 0.32 g/kg quercetin.
