Effect of Heat Processing on Quality of Pasteurized Oysters

ABSTRACT Constant heating time at different temperatures and constant temperature with different heating times combinations were studied to determine optimum heat process for oyster pasteurization in plastic pouches. Heating 8 min at 75–76°C gave optimum product physical and sensory quality. Crude amylase and peroxidase extracts from oysters were inactivated by optimum treatment, but lipase retained about 15% of activity.
