Abstract:Traditional low temperature freezing easily leads to drip loss，tissue rout and biological activity loss of product after thaw. The study and technology of lowerring super-cooling degree and inhibiting the growth of ice crystal with the assit of electric field，magnetic field and ultrasound was introduced. The principle，advantages， disadvantages and use of vacuum cooling technology was introduced. Microwave assisted frozen，high pressure freezing technology and cryoprotectant assited vitrification frozen was introduced. The study and development of new freezing technology was expected under the new business model.
