Food technologies

Food technologies can improve convenience, shelf life, and microbial safety, but each method has particular limitations. Safe outcomes depend on the food, process conditions, packaging, and subsequent storage and handling.

This section introduces microwave heating, food irradiation, and high-pressure processing. These methods do not replace good hygiene, appropriate refrigeration, or validated controls for specific foods.
