| Abstract: |
| With peroxide value as index，and blank sample and sample added with TBHQ as comparisons，the antioxidative effects of tea polyphenols，rosmarinic acid，dihydromyricetin and vitamin E on yellow cheek carp viscera oil were studied by Schaal oven-storage method. The results showed that the antioxidative effect of TBHQ was the strongest，followed by dihydromyricetin，tea polyphenols，rosmarinic acid and vitamin E when the dosages of antioxidants were all 0.02%；the optimal dosages of tea polyphenols，rosmarinic acid and dihydromyricetin were 0.04%，0.06% and 0.04%，respectively；vitamin C had a synergistic effect on tea polyphenols and dihydromyricetin；the optimal combination of natural antioxidants was 0.02% dihydromyricetin+0.02% tea polyphenols with 0.02% VC as synergist，and the antioxidative effect of the natural compound antioxidants on yellow cheek carp viscera oil was stronger than that of single natural antioxidant，closed to that of TBHQ. |
