Abstract
[ Objective ] The research aimed to discuss a new method for the rapid and repeatable oxidation of soybean oil and an evaluation index system for its oxidation degree. [ Method ] In home-made oxidation device and under oxidation conditions, the acid value (AV), peroxide value ( POV),iodine value ( Ⅳ ), thiobarbituric acid reactive substances (TBARS) and fat acid of the unrefined soybean oil were determined at 0,7,14,16 and 18 d repecfively. [Result] under 80 ℃ in the home-made device,the POV and TBARS of the soybean oil changed significantly,therefore,they could act as an indicator of rapid oxidation,the oxidation rate slowed down after 18 days;the AV,Ⅳ and TBARS of the soybean oil and the oxidation duration showed a quadratic variation,while its POV and oxidation duration showed a exponential variation. Compare with 0 d ,AV,POV and TBARS significantly increased respectively by 1.7, 29.0 and 19.0 times ( P ＜ 0. 05 ), but Ⅳ significantly decreased by 0. 91 times ( P ＜ 0.05 ); UFA significantly decreased from 84.0％ to 82.2％ (P ＜ 0. 05). There were no significant difference of POV,TBARS, SFA and UFA betewen 16 d and 18 d of oxidation (P＞0.05). [Conclusion] The research determined the variation of the oxidation index in the home-made device at different time and provided references for the test model of the hepatopancreas damage of fishes.关键词
