Abstract: There is disclosed a process for producing a lipoprotein-containing substance having a reduced lipid content. The lipid content is reduced by treating a lipoprotein-containing substance with at least one enzyme selected from the group consisting of proteolytic enzymes and lipolytic enzymes and then bringing the substance into contact with a sub- or supercritical fluid to extract a lipid from the substance. The lipid extracted from the substance is separated from the fluid which may be used again in the extraction step. Also disclosed is a food whose raw material is a lipoprotein-containing substance having a reduced lipid content obtained by the above process.

Abstract: A liquid egg having a reduced cholesterol content and a flavor and taste which is comparable to conventional liquid egg is disclosed. The liquid egg is produced by contacting liquid egg with a supercritical fluid to extract cholesterol from the liquid egg.

Abstract: A process for producing liquid egg having a reduced cholesterol content having flavor and taste comparable to conventional liquid egg having a normal cholesterol content is disclosed. The liquid egg having a reduced cholesterol content is produced by contacting liquid egg with a supercritical fluid to extract cholesterol from the liquid egg. Food whose raw material is the liquid egg having a reduced cholesterol content produced by the above process is also disclosed, as well as a new use for a wetted wall column system for producing the liquid egg noted above.
