摘  要:
应用超临界CO2萃取技术,研究了蛋黄粉中蛋黄油的脱除工艺。结果表明,用乙醇作溶剂萃取蛋黄残粉中的卵磷脂并进行纯化,得到了精制卵磷脂,经测定,磷脂酰胆碱含量为91.80 g/100g,蛋白质含量为8.69 g/100g,丙酮不溶物含量为90.40 g/100g。

摘  要:
The discarding process of egg yolk oil from egg yolk powder was studied by using superitical fluid CO2 extraction.Extracting the lecithin with alcohol from residue egg yolk powder and refining,the refined lecithin was gotten.Through de-terming,it contented:1.phosphtidylcholine 91.8 g/100g;2.protein 8.69 g/100g;3.in acetone material insoluble 90.4 g/100g.
