Japan developed fresh packaging materials

In recent years, the development of a new generation of packaging materials that controls and inhibits the overcooking of fresh foods to prevent food rot has risen in Japan.

It has been found that different vegetables and fruits can be ripened with different amounts of ethylene gas. It is also found that vegetables and fruits produce some ethylene gas when they rot. This gas will further promote the rapid ripening of other vegetables and fruits. Causes rot. Therefore, if the absorption of this ethylene gas is controlled, the preservation effect of the stock can be achieved.

According to this principle, the Japan Food Circulation System Association has developed a corrugated paper with cristobalite powder; Showa Biochemical Co., Ltd. infiltrated calcium phosphate as a raw material into absorbent paper to make a wrapping paper; The company tried to mix a high-purity calcium phosphate or polyethylene film into a new packaging film or mix it into corrugated paper to make a new packaging material.

These new packaging materials have the function of absorbing ethylene gas, and calcium phosphate also has the function of absorbing carbon dioxide and inhibiting the decomposition of chlorophyll. It is said that its preservation effect is comparable to that of a refrigerator car.
