aseptic packaging. Process in which a food product, such as ultra high temperature (UHT) milk) and its package is sterilized separately and then combined and sealed under sterilized atmosphere. In comparison, in a canning process both the item and packaging are sealed as one unit and then heated to sterilize them together.
A newer unit is the agitating retort, which mechanically moves the can and the food, providing quicker heat penetration. In the aseptic. packaging process, the problem with slow heat penetration in the in-container process are avoided by. sterilizing and cooling the food separate from the container.
