Abstract

为提高牡丹籽油乳液的氧化稳定性，将叔丁基对苯二酚（TBHQ）与天然抗氧化剂（生育酚、抗坏血酸）进行复配，测定不同抗氧化剂对牡丹籽油乳液的抗氧化作用，并分析了不同复配抗氧化剂的相互作用机制。结果表明：在贮藏30 d时，添加和未添加抗氧化剂牡丹籽油乳液的粒径相较于0 d 均略有增加，200 mg/kg TBHQ与800 mg/kg抗坏血酸复配时乳液的Zeta电位绝对值最大，且抗氧化作用最强；TBHQ与抗坏血酸表现出较好的协同抗氧化作用，与生育酚表现出拮抗作用；TBHQ与生育酚之间拮抗作用的原因主要是TBHQ减少了生育酚在牡丹籽油乳液中油水界面的含量，而TBHQ与抗坏血酸之间协同作用主要是由于抗坏血酸增加了TBHQ在牡丹籽油乳液中油水界面的含量。综上，TBHQ与抗坏血酸复配能提高牡丹籽油乳液的氧化稳定性。In order to improve the oxidative stability of peony seed oil emulsion, tert-butylhydroquinone (TBHQ) was complexed with natural antioxidants (tocopherol and ascorbic acid), and the antioxidant effects of different antioxidants on the peony seed oil emulsion were determined and the mechanism of interaction between the different complexed antioxidants was analyzed. The results showed that the particle size of peony seed oil emulsion with and without antioxidants increased slightly at the 30 d of storage compared with that at the 0 d of storage. The absolute value of the Zeta potential of the emulsion added with 200 mg/kg TBHQ and 800 mg/kg ascorbic acid was the largest and the antioxidant effect was the strongest. TBHQ showed better synergistic antioxidant effect with ascorbic acid, and antagonistic effect with tocopherol. The antagonistic effect between TBHQ and tocopherol was mainly due to the fact that TBHQ reduced the content of tocopherol in the oil-water interface in peony seed oil emulsion, while the synergistic effect between TBHQ and ascorbic acid was mainly due to the fact that ascorbic acid increased the content of TBHQ in the oil-water interface in peony seed oil emulsion. In conclusion, the combination of TBHQ and ascorbic acid can effectively improve the oxidation stability of peony seed oil emulsion.
