U.S. and Japan study potato packaging technology

The U.S. has developed ultra-high gas permeable membranes that allow sufficient oxygen to pass through, thus avoiding anaerobic conditions and achieving optimal atmosphere control and preservation. Specific operations are: (1) radiation treatment; (2) coating treatment; (3) strict selection ticking, timely harvest; (4) clean storage.

Japan's dehydration and fresh-keeping packaging technology uses highly absorbent polymers and activated carbon placed in bag-like mats to regulate moisture by absorbing the moisture released from potato respiration. At the same time, it can absorb gases such as ethylene produced by breathing and absorb rancid odors to prevent condensation. Another is the use of SC film, which also has the function of absorbing ethylene and water vapor, can prevent condensation, but also can adjust the concentration of oxygen and carbon dioxide in the package, also has a set of anti-corrosion effect. The SC film has good transparency and low price, and can prevent the potato from frothing and spoiling due to water evaporation and microbial action. The SC film has good flexibility, is not easy to break, can be used stably for a long time, and has good preservation effect.
