为了探究微波预处理对油茶籽毛油抗氧化性的影响,了解油茶籽毛油中抗氧物质的变化规律。以油茶籽仁为原料,研究微波预处理后油清除自由基能力及油中抗氧物质的含量及其抗氧能力变化。结果表明,微波预处理对油茶籽毛油抗氧化能力有显著影响。在700 W 20 min处油茶籽毛油DPPH含量有最大值,为(337.08 ± 6.07)μg TE /g。微波预处理后总酚含量呈现上升趋势,含量最高为700 W 20 min处,为(193.04 ± 9.38)μg GAE/g。其ABTS阳离子自由基清除能力小于FRAP还原能力。美拉德产物含量经微波预处理后变化显著,5 -羟甲基糠醛(5 - HMF)在560 W 20 min处有最大值,为(26.76 ± 1.46)μg /g,丙酮醛(MGO)和3 -脱...

In order to explore the effect of microwave pretreatment on antioxidantion in virgin oil of Camellia oleifera seed, and understand the change of antioxidants in virgin oil of Camellia oleifera seed. Camellia oleifera seed kernels were used as raw materials to study the free radical scavenging ability of oil, changes of antioxidant content and antioxidant capacity in oil after microwave pretreatment in the present study. The results showed that microwave pretreatment had a significant effect on the antioxidant capacity of Camellia oleifera seed ...
