Food preservation technology is the use of radiation irradiation food methods to achieve inhibition of germination, insecticidal, sterilization, adjust the degree of maturity to maintain food freshness and health, extend the shelf life and storage period, so as to reduce the loss of food to save a technology.

Radiation food preservation advantages:

(1) the treatment process of raw materials generated by the heat is very small, the processed raw material temperature is almost not increased, can be more limited to preserve the quality characteristics of raw materials, even in the frozen state can be processed, is a "cold" sterilization method.

(2) kill microbial effect is significant, the dosage can be adjusted.

(3) radiation penetration is strong, uniform, instantaneous, compared with other methods, the irradiation process can be more accurately controlled.

(4) processed food without additives and other chemical components added.

(5) can be packaged or stacked raw materials for sterilization, the method is convenient and quick.

(6) Irradiation technology processing cost is low, energy consumption is low.
