采用4种方法脱除花生油中黄曲霉毒素B1(aflatoxin B1,AFB1),对比研究4种方法的脱除效果以及对花生油酸价、过氧化值、VE含量、植物甾醇含量的影响。探究碱法脱除花生油中黄曲霉毒素的作用机理、安全性、油中游离碱残留及花生油风味的影响。花生(三级)经压榨后油中AFB1含量为21.50 μg/kg,经碱液处理(碱液pH 13.44、碱液占花生质量10%、30 min)后花生油AFB1残留量降至2.00 μg/kg,脱除率90.7%;膨润土一次吸附(膨润土用量质量分数2.0%、吸附时间30 min)花生油AFB1残留量为0.13 μg/kg,脱除率99.4%;膨润土复吸(首次吸附用量质量分数1.0%、复吸用量质量分数0.5%、每次吸附时间30 min)花生油AFB1残留...

Four methods were compared for their removal efficiencies for aflatoxin B1 (AFB1) from peanut oil as well as their effects on the acid value (AV), peroxide value (POV), vitamin E (VE) content and phytosterol content of peanut oil. The mechanism of AFB1 removal by alkali treatment was explored, and the safety, free alkali residue and flavor of peanut oil after being treated with alkali were further evaluated. The content of AFB1 in crude peanut oil was 21.50 μg/kg, and decreased to 2.00 μg/kg (removal efficiency of 90.7%) after 30 min alkali t...
