FreshUs is oxygen absorber to protect packaged foods and other products against spoilage, mold growth, color change, loss of nutritive values, insect damage and loss of quality. By removing residual oxygen inside packaging to below 0.01% FreshUs effectively preserve packaged foods without use of food additives and preservatives. FreshUs not only extends shelf life but keeps product quality as was.

Compared to other packaging methods FreshUs shows better performance as shown in the chart below. FreshUs can replace or combine with these conventional Gas Flushing or Vacuum and back flushing methods to ensure product quality and extend shelf life.

Reactions in Packaging
* Mold has been shown to grow in 20 days at 25 deg C at 0.2% residual oxygen (From "Techniques for the preservation of food by employment of an oxygen absorber," Nakamura and Hoshino, 1983)

M-type FreshUs is used in an environment where enough moisture exists such as fresh or precooked pasta or noodles, and Cheese & dairy products packaging. Moisture inside packaging is used to activate FreshUs to work. Thus M-type FreshUs is more resistant than S-type on exposure to the air if humidity level is low enough. And M-type FreshUs is recommended to use in packaging in about 6 hours once open the master bag.
