PASTEURIZATION DESIGN CRITERIA FOR PRODUCTION OF EXTENDED SHELF-LIFE REFRIGERATED LIQUID WHOLE EGG

Abstract
Pasteurization schedules of liquid whole egg are designed for inactivation of pathogens. Postprocess contamination and survival of heat-resistant spoilage bacteria make it necessary to keep the product frozen for extended shelf-life. Criteria required for production of a refrigerated pasteurized liquid whole egg are discussed. Pasteurization schedules which yield up to 5% soluble protein loss are suggested as the highest level of heat treatment. A combination of such heat treatment and aseptic packaging is suggested as a potential route for production of a long shelf-life pasteurized liquid whole egg.
