VE复合抗氧化剂在猪油中的抗氧化性能研究

Research of VE Composite Antioxidant Properties in lard

以VE,VE分别与茶多酚、迷迭香、硫辛酸、槲皮素的复合物为抗氧化剂,添加到猪油中,比对其抗氧化性能。结果表明:VE、茶多酚、迷迭香、硫辛酸、槲皮素都具有一定的抗氧化效果,相同添加量的情况下单品的抗氧化能力大小顺序为:槲皮素>茶多酚>迷迭香>硫辛酸>VE;VE与四种天然的抗氧化剂1∶1进行复合以后与单一的抗氧化剂相比都具有一定的增效作用。

Use VE and VE respectively with the tea polyphenols,rosemary,lipoic acid and quercetin as composite antioxidant,added to the lard oil,compare the oxidation resistance.Results show that： VE,tea polyphenol,rosemary,lipoic acid and quercetin have certain of antioxidant effect,under the same additives the antioxidation ability order is： quercetintea polyphenolrosemarythioctic acidVE;VE with four single natural antioxidants 1∶1 composite compared with single antioxidants have synergy.
