摘要:

制备茶多酚在亚油酸-水-乙醇体系的反相微乳液,使其成功地添加到亚油酸中,并研究该微乳液体系的相形为、电导率、粒径分布、流变及抗氧化能力等特性。结果表明:当油相亚油酸质量分数大于24% 时,可形成油包水型微乳液。该微乳液体系粒径均一,表现为剪切变稀的流变特征,且具有温度触变性。过氧化值测试结果表明:相比空白微乳液,水相添加0.01 g/mL茶多酚对亚油酸氧化的抑制率为68.32%,添加0.1 g/mL茶多酚对亚油酸氧化的抑制率为92.42%。

Abstract:

Water in oil (W/O) microemulison (ME) of linoleic acid/ethanol/H2O to envelop tea polyphenols was prepared.
The ternary phase diagram, electrical conductivity, particle size, rheological behavior and oxidation resistance ability of the
microemulison were investigated. The results showed that the W/O microemulsion was formed when linoleic content was
above 24%. This ME, characterized as pseudoplastic and temperature thixotropy, had an uniform particle size. It was found
by determining peroxide value that compared with the blank, the inhibition rates of linoleic acid oxidation for microemulsion
with adding 0.01 and 0.1mg/mL tea polyphenols were 68.32% and 92.42%, respectively.
Key words: linoleic acid; tea polyphenols; inverse microemulsion; antioxidant
