Freshness retainer "Shinsenban

When placed in the vegetable compartment of a refrigerator, "Shinsenban" uses the power of carbon dioxide (CO2) to create a low-oxygen state inside the compartment, slowing down the respiration process that causes vegetables to age. This action suppresses the depletion of water and nutrients, and keeps vegetables fresh by putting them to sleep.


Carbon dioxide gas permeates through plastic bags for storage and reaches the effective concentration necessary to maintain freshness approximately two hours after installation of "Shinsenban. It is said to be effective even for vegetables in bags.

Since vegetables continue to breathe and age after harvesting, it is particularly effective for leafy vegetables such as lettuce, spinach, and komatsuna, which have a high respiration rate. The freshness retention effect lasts for about 3 months (may vary depending on the type of vegetable, the environment of the vegetable room, and the season).
