Sterilization refers to the complete annihilation of microorganisms and bacteria. It is used primarily on food processing equipment as well as on medical or microbiology equipment. Hot-air sterilization is used on objects made from glass, metal, or porcelain, and takes at least 30 minutes at a temperature of 180°C.
For the purpose of preserving it, food is sterilized at temperatures above 100°C. However, it often loses its nutritional value and flavor during this process.
