| 摘 要： | 采用超临界CO2萃取，对去除蛋白黄粉中胆固醇和甘油三酯进行了研究，市购鲜鸡蛋去壳、分别收集湿蛋白和蛋黄，在45℃下分别真空干燥，得蛋白粉和蛋黄粉，取蛋黄粉装入高压釜中，进行超临界CO2循环萃取，通过正交试验得最佳工艺条件是：A萃取压力为31.5MPa，B萃取温度40℃，C被萃取蛋黄粉重300g，D萃取时间3h，所得蛋黄粉中胆固醇和甘油三酯等中性脂的残留量质量分数仅为0.019%，与不含此类旨质的蛋白粉混合，制成几乎不含胆固醇和甘油三酯的高级绿色保健营养食品－－鸡蛋粉。

| Abstract: | Supercritical CO2 Fluid Extraction in gett ing rid of Cholesterol and Triacylglycerols(TG) from yolk powder is studied . Wet egg white and yolk collected from fr esh egg were dried in vacuum at the temperature of 45 ℃.Yolk powder was put into high pressure jar and t hen extracted by cycle in supercritical CO2 fluid. After the orthogonal test, the best technology conditions were found as follows: 1) the extraction pres sure was 31.5 Mpa; 2)the extraction temperature was 40 ℃; 3) the extraction weight was 300 g;4) the extraction time was 3 h.The remnants of Cholesterol and TG etc in yolk po wder was only 0.019%. A low-fat health food may thus be developed. |
