Effect of natural antioxidant on antioxidant properties of chili chicken oil
In order to screen natural antioxidants suitable for chili chicken oil and extend its shelf life,the effects of six natural antioxidants(rosemary extract,vitamin E,tea polyphenols,vitamin C,quercetin and lipoic acid)on the acid value,peroxide value,DPPH radical scavenging capacity,and total reducing capacity of chili chicken oil were investigated and compared.The results showed that six natural antioxidants had certain antioxidant capacity in chili chicken oil;in inhibiting acid value,quercetin was the most effective and vitamin C was the worst;in inhibiting peroxide value,quercetin was the best and vitamin E was the worst;in terms of DPPH radical scavenging capacity,rosemary extract was the most effective and lipoic acid was the worst;in terms of total reducing capacity,quercetin was the most effective and vitamin E was the worst.Quercetin,rosemary extract and tea polyphenols were in the top three in terms of acid value,peroxide value,DPPH radical scavenging capacity and total reducing capacity.Considering the antioxidant effect,antioxidant stability and cost,rosemary extract and tea polyphenols can be preferred as antioxidants for chili chicken oil to improve its storage performance.
