Retort Control in the Food Industry using the C360 AG/RCP-007_2 The Cook Period This period is essential in order to cook the product thoroughly, thereby destroying any organisms that could later spoil it. These organisms, called spores, are able to withstand several hours of atmospheric boiling water temperature, but are destroyed in a short time at a temperature of 116 to 121°C (240 to 250°F).
Retort Control in the Food Industry using the C360 AG/RCP-007_2 The Retort Process – Product in glass jars is processed in a water-filled retort that is heated with steam. The topmost jars must be covered by 100 to 150mm (4 to 6in.) of water throughout the Water Cooking cycle and the water must be agitated to provide uniform cooking.
