摘要
在常温及加热110℃灭酶条件下,研究了大蒜未水解、不同水解时间、常温水解、50℃水解等情形对猪油、菜籽油的抗氧化效果。采用Schaal烘箱法,按GB/T5538检测过氧化值(POV),用相对防效值评价抗氧化效果。试验结果表明:1)未水解大蒜中存在抗油脂氧化的成分,大蒜水解后的效果明显好于未水解的,常温水解时间从0.5 h～5 h抗氧化效果有提高但不明显,水解温度高抗氧化效果反而下降;2)对菜籽油的抗氧化效果明显优于猪油;3)大蒜水解后直接常温使用的抗油脂氧化效果好于110℃灭酶使用;4)抗油脂氧化效果:大蒜素>大蒜素分解物质>大蒜未水解所含成分。
At room temperature and at 110 ℃ （enzyme destroyed）, antioxidant effect of both lard oil and colza oil was respectively studied in presence of garlic in different states： un-hydrolyzed, hydrolyzed within different time length, hydrolyzed at 50 ℃, and hydrolyzed at room temperature. According to standard GB/T5538, the antioxidant effect was reflected from the relative controlling efficacy of the peroxide value （POV） via the Schaal drying oven method. The following results were obtained： 1） the un-hydrolyzed garlic could enhance the antioxidant effect and the hydrolyzed garlic was even better, but the time length of hydrolysis between 0.5 h and 5 h at room temperature made no obvious difference, and the elevated temperature was disadvantageous to the hydrolysis of garlic; 2） antioxidant effect of the colza oil was more evident than the lard oil; 3） room temperature is preferred to 110 ℃ for the use of the hydrolyzed garlic; 4） antioxidant effect owing to the garlicin, the ingredients of decomposed garlicin, and the un-hydrolyzed garlic, decreased successively.
