摘要
为考察微波预处理对高油酸花生油的品质及抗氧化活性的影响,以鲁花19为原料,通过优化微波提取工艺得到高油酸花生油,并对其出油率及酸价(AV)、过氧化值(POV)、氧化稳定指数(OSI)、脂肪酸组成、及VE含量进行分析.结果表明:微波预处理工艺可显著提高高油酸花生油的出油率;微波时间为6～7 min时,高油酸花生油的酸价和抗氧化能力最高,过氧化值最低;微波时间对其脂肪酸组成及VE含量没有显著性影响,但是可以显著增加高油酸花生油的菜油甾醇、豆甾醇、β-谷甾醇三种甾醇含量.
Abstract
In order to investigate the effect of microwave pretreatment on the quality and an-tioxid-ant activity of high oleic acid peanut oil,with LuHua 19 as raw material,high oleic acid peanut oil was obtained by optimizing microwave extraction process.The oil yield of high oleic acid pea-nut and the acid value(AV),color,valueperoxide value(POV),oxidation stability in-dex(OSI),fa-tty acid composition,and alpha-VE content of high oleic acid peanut oil were an-alyzed.The results showed that microwave pretreatment could beneficial to improve the oil yield of high oleic acid peanut oil.When the microwave time was 6-7 min,the acid value and antioxi-dant capacity of hi-gh oleic acid peanut oil were the highest and the peroxide value was the low-est.Microwave time had no significant effect on its fatty acid composition and VE content,but it could significantly increase the contents of three sterols:campesterol,stigmasterol and beta-sitosterol.
