Acoustic Extra Freezing (AEF) builds industrial freezing equipment that uses acoustic waves to create nano-sized ice crystals. Smaller crystals protect the food’s cell structure, so frozen products keep their taste, texture, colour and nutritional value during long-term storage.
Its freezing chambers are aimed at fish and seafood processors, meat, fruit and vegetable processors, ready-meal makers and food service. AEF is based in Helsinki, Finland, and was founded in 2019.
