Abstract

Abstract: Removal of cholesterol from egg yolk powder was investigated with supercritical carbon dioxide extractionat 40℃/20-30MPa for 1 ～4h.The results showed that supercritical carbon dioxide could remove cholesterol from eggyolk pox,,der with the best selectivity at 30MPa .phospholipids and protein were concentrated under this condition.Andextraction time did not change the pressure selectivity for cholesterol during the extraction procedure,but cholesterolremoval ratio was greatly increased with extraction time.

Key words: , Supercritical carbon dioxide Cholesterlo Egg yolk；
