What You Need to Know
Radio frequency heating is a non-ionizing form of electromagnetic radiation that causes water molecules to rotate and collide, generating heat, and can be used for pasteurization, sterilization, and cooking of various foods.
Steps
- 1.
RF-pasteurized eggs (United States): Kills pathogens while preserving raw egg texture
- 2.
RF-blanched vegetables (Japan): Even enzyme inactivation without water leaching
- 3.
RF-thawed seafood (Norway): Rapid defrosting with minimal quality loss
