摘要
研究了花生油的水化脱胶工艺,考察离心转速、加水量、电解质、恒温时间、恒温温度等因素对花生油水化脱胶效果的影响。采用比色法检测脱胶花生油磷脂含量,通过对磷脂含量的分析讨论,最终确定花生油水化脱胶的最优工艺条件为:预热温度75℃,按每100g油加入1mL浓度为8%的柠檬酸溶液,搅拌时间5min,恒温温度80℃,恒温时间20min,4200r/min的转速离心20min。用柠檬酸水化复合脱胶工艺对花生油进行脱胶处理,可得到符合脱胶要求的脱胶油。
The progress of hydrated degumming of peanut oil was studied.Effects of different experimental conditions on the degumming,rotational speed,amount of water,electrolyte,holding time,temperature were studied.The optimum technological conditions for degumming process of the peanut oil were determined by the analysis of the content of phospholipid of degummed crude oil.The optimum technological conditions was：preheating at 75℃,1mL citric acid solution with the concentration of 8% added into 100g oil,reaction time of 5min and constant temperature of 80℃ for 20min,4200r/min rotational speed offcenter for 20min.The produced peanut oil from the optimized hydrated degumming process with the addition of citric acid meets the requirements of the degumming oil.
