摘要
以脱胶率为指标,分别研究了温度、时间、水添加量和磷酸添加量4个因素对胡麻籽油脱胶效果的影响。基于单因素和Box-Behnken中心组合试验设计原理,优化胡麻籽油脱胶条件。结果表明,胡麻籽油常规水化法脱胶最佳工艺条件:温度为63.7℃,时间为33.8min,水添加量为3.30%,磷酸添加量为0.45%;模型预测胡麻籽油脱胶率为79.65%,实测值为79.10%。脱胶后的胡麻籽油色泽,水分及挥发物、过氧化值、酸价均符合亚麻籽油原油标准。
In order to improve the quality of flax oil,the conventional hydration method was used to optimize the degumming process conditions and analyze the main physicochemical indexes.Taking the degumming rate as an indicator,the effects of temperature,time,water addition and phosphoric acid addition on the degumming effect of flax seed oil were studied respectively.Optimizing the degumming conditions of flax seed oil based on single factor and Box-Behnken center combination experimental design principle.The results showed that the best process conditions for degumming by conventional hydration method of flax seed oil:the temperature of 63.7℃,the time of 33.8 min,the amount of water added of 3.30%,and the amount of phosphoric acid added of 0.45%.The model predicts the degumming rate of flax seed oil is 79.65%,and the measured value is 79.10%.After degumming,the color, moisture,volatile matter,peroxide value,and acid value of flax seed oil meet the crude oil standard of flax seed oil.
