During the sterilization process which follows, the cans are subjected to steam or boiling water, with the temperature and duration varying according to the type of food. Cans of fruit, for example, take only 5-10 minutes in boiling water, while meat and fish are cooked at higher temperatures for longer periods. After sterilization, the cans are cooled quickly to 32о C. to prevent the contents from becoming too soft. The final stage before despatch to the wholesale or retail grocer is labelling, and packing the tins into boxes. Nowadays, however, labeling is often printed on in advance by the can-maker and no paper labels are then required.
