The invention enables processing eggs, especially low-cholesterol egg products based principally on egg whites, at high temperatures to provide liquid, pasteurized egg products which exhibit improved stability during refrigerated storage. Liquid egg composition is heated to a temperature (e.g. 60.degree. to 75.degree. C.) and for a time effective to reduce the population of viable organisms with some coagulation of the conalbumin, but without significantly coagulating the ovalbumin. A dispersion of coagulated conalbumin in a liquid matrix is homogenized (average particle size is preferably less than 2 microns) to form a smooth-textured, liquid egg composition. The resulting liquid egg compositions have unique textural and visual characteristics.
In a process for preparing a packaged, pasteurized liquid egg product by heating a liquid egg composition consisting essentially of egg white having a population of viable organisms and containing conalbumin and ovalbumin, to a pasteurization temperature and holding the composition at that temperature for a time period effective to reduce the population of viable microorganisms, cooling the pasteurized egg composition, and packaging the egg composition in a sealed container, the improvement comprising:
A packaged low-cholesterol, opaque, smooth-textured liquid egg composition comprising at least 95% egg white containing conalbumin and ovalbumin, comprising at least 50% of the conalbumin coagulated and particulated as a dispersion of finely-divided particles of an average particle size of less than 2 microns in a liquid matrix wherein said ovalbumin is not significantly coagulated.
