With the development of technology and economy and the improvement of material civilization and the improvement of the regulations, the radiation processing is a global trend, and it has a bright future. By irradiation of food, for example, the development of food irradiation technology began in the 1940s, all over the world, many experts and scholars in the radiation process, radiation chemistry, radiation biology, microbiology, nutrition and toxicology etc. are carried out a large amount of experimental work related to irradiated food safety research reports of thousands of. Food irradiation is a kind of physical process, which belongs to cold working, low energy consumption, no need to add chemical drugs, there is no problem, it can keep the original color, smell and taste of food, which is very important for food and not suitable for high temperature sterilization. To institutions and the World Health Organization jointly funded and irradiated food safety joint expert committee "was established in 1963, the commission from 1963 to 1980 has held a number of meetings, according to years of research and experiments to accumulate, in 1980 formally to the rest of the world put forward by the food and Agriculture Organization of the United Nations, the International Atomic:" any food by the irradiation of 10KGy following exposure and are not due to radiation induced toxicity. Therefore, the food processed by irradiation is safe and safe, and it will not need to be tested in toxicology, and it is also safe in nutrition and microbiology. In 1997, the Commission's high dose research group announced that it was safe to exceed 10KGy high dose radiation. These conclusions have greatly promoted the development of the industry in the world, and have been accepted internationally!
 

In June 1997, the national standard of six major categories of food was formally promulgated.

First:

"Hygienic standard for cooked meat and poultry meat" GB14891.1-1997

Second:

"Irradiation of dried fruit, preserved fruit health standards" GB14891.3-1997

Third:

"Health standard for the health of the exposure to the spice" GB14891.4-1997

Fourth:

Fresh fruits and vegetables "radiation hygiene standards" GB14891.5-1997

Fifth:

"Hygienic standard for meat and poultry meat" GB14891.7-1997

Sixth:

"Hygienic standard for irradiated beans, cereals and their products" GB14891.8-1997
