Abstract
A food product, such as fruit or vegetables either whole or in pieces, or in the form of a pulp, or meat in pieces, is preserved by feeding hot liquid or steam into a contained body of the product to sterilize the product. Some liquid is retained in the product which is sealed in a container under aseptic conditions. The sterilization preferably takes place in the container in which the sterile product is ultimately sealed.
