中文摘要:
      以苯并芘超标的浓香菜籽毛油为原料,通过单因素实验和正交实验研究低温脱胶过程中,脱胶静置时间、脱胶温度、加水量和磷酸添加量对浓香菜籽油中苯并芘去除效果的影响。结果表明,在脱胶静置时间60 min、脱胶温度20?℃、加水量3%、磷酸添加量0.1%的工艺条件下,浓香菜籽油中苯并芘去除率为83%,苯并芘含量为2.04 μg/kg,水分含量为0.15%,所得浓香菜籽油风味浓郁醇厚,280?℃加热试验合格。
英文摘要:
      The crude fragrant rapeseed oil with excessive benzopyrene was selected as raw material. The effects of degumming standing time, degumming temperature, water dosage and phosphoric acid dosage on the removal of benzopyrene in fragrant rapeseed oil were analyzed in the low temperature degumming process by single factor experiment and orthogonal experiment. The results showed that the optimal conditions of the degumming process were obtained as follows: degumming standing time 60 min, degumming temperature 20?℃, water dosage 3%, phosphoric acid dosage 0.1%. Under the optimal conditions, the removal rate, content of benzopyrene and water content in fragrant rapeseed oil were 83%, 2.04 μg/kg and 0.15% respectively. After degumming, the rapeseed oil had a strong flavor and the 280?℃ heating test was qualified.
