抗坏血酸棕榈酸酯对植物油的抗氧化作用Antioxidative effect of L-ascorbyl palmitate on vegetable oil
旨在为酶法和化学法抗坏血酸棕榈酸酯(L-AP)在植物油中的应用提供参考,并为家庭储存植物油的方法提供建议,以酸值和过氧化值为指标,模拟家庭储存条件,分别考察低温(20 ℃)避光、常温(25 ℃)曝光、高温(60 ℃)避光,满瓶或半瓶等条件下两种L-AP对菜籽油的抗氧化效果,并与叔丁基对苯二酚(TBHQ)、维生素E(VE)和脂溶性茶多酚等抗氧化剂进行比较,采用Rancimat法测定添加不同抗氧化剂的菜籽油、大豆油、棕榈油和亚麻籽油的氧化诱导时间。结果表明:酶法L-AP和化学法L-AP对植物油的抗氧化作用相似,且抗氧化能力与脂溶性茶多酚相当,强于VE。植物油在低温(20 ℃)避光、满瓶条件下储存,...
