摘要
针对常规油脂脱色存在油脂色泽过浅的问题,以活性白土作对比,将二氧化硅用于葵花籽油的脱色,通过测定不同添加量二氧化硅脱色葵花籽油的色泽、杂质含量、氧化诱导期及风险物质含量,考察二氧化硅的吸附脱色效果。结果表明:二氧化硅(0.1%~0.5%)添加量脱色葵花籽油的磷含量、苯并(a)芘和黄曲霉毒素B1含量与0.5%活性白土脱色葵花籽油的相当,但与0.5%活性白土相比,0.1%二氧化硅脱色可以在保持葵花籽油色泽的同时,达到葵花籽油中的皂未检出和氧化诱导期显著延长的效果,说明二氧化硅在食用油中具有较好的吸附脱色效果。
For the problem of light color of oil in conventional bleaching,silica was used for bleaching of sunflower seed oil in comparison with activated white clay,and the color,impurity content,oxidation induction period and risk substance content in sunflower seed oil bleached by different additions of silica were measured to examine the adsorption bleaching effect of silica.The results showed that the contents of phosphorus,benzo(a)pyrene and aflatoxin B1 of silica(dosage 0.1%-0.5%)bleached sunflower seed oil were comparable to those of 0.5%activated white clay bleached sunflower seed oil,but compared with 0.5%activated white clay,the bleaching of 0.1%silica could maintain the color of sunflower seed oil,the soap was undetectable,and the oxidation induction period was significantly prolonged,indicating that silica had a better adsorption bleaching effect in edible oil.
