鸡蛋黄中提取卵磷脂的最佳工艺条件

The optimum condition for abstraction of phosphatidy- lcholine from egg yolk

采用3因素正交试验从鸡蛋黄中提取卵磷脂,结果表明,提取卵磷脂的最佳工艺为:用分析纯丙酮,丙酮用量与蛋黄之比(mL/g)为3 : 1,静置15 min,得到滤渣丙酮粉,再用浓度99.7 % 的乙醇溶解丙酮粉,温度40 ℃,用量为每克丙酮粉用9.5 mL乙醇。

ion of the phosphatidylcholine used in food industry from egg yolk with acetone ethanol. It turns out that the result is best with 99.7 % of ethanol, 9.5 mL/g of ethanol` number and temperature of 40℃.
