FreshPax® Packets are oxygen absorbers designed to protect packaged foods and other products against spoilage, mold growth, color change, rancidity, loss of nutritive values, and loss of quality. FreshPax Packets irreversibly absorb oxygen inside sealed packaging to less than 0.01% and maintains this level.
A study conducted by the Department of Food Science at Cornell University concluded that FreshPax Packets are effective in extending the shelf life of oxygen-sensitive foods and other products. Even under extreme testing conditions, the use of FreshPax Packets in commercial cheese and bread resulted in a decrease in mold spoilage and a considerable shelf life extension.
The study also indicated that FreshPax packets can reduce the formation of n-hexanal and other volatile compounds in high-fat snack foods susceptible to oxidative rancidity*.
FreshPax Packets when used in combination with your current packaging methods, including gas flushing and vacuum packaging, decrease time to deoxygenate the environment. Gas flushing and vacuum packaging merely serve to dilute oxygen, which can lead to food spoilage, odors, and microbial growth. FreshPax Packets modify the package atmosphere by reducing oxygen levels below those possible with vacuum packaging and gas flushing.
|FreshPax Packets||Reduces and maintains oxygen content in packaging to below 0.01%||Limits growth of aerobic organisms and oxidative chemical reactions in packaging.|
|Vacuum and Back Flush||Reduces to only 0.1% residual oxygen||Temporarily controls microbial growth*|
|Gas Flushing||Reduces to approximately 0.5% to 5% oxygen||Provides minimal control of aerobic microbial growth*|
*Mold has been shown to grow in 20 days at 25°C at 0.2% residual oxygen (From “Techniques for the Preservation of Food by Employment of an Oxygen Absorber,” Nakamura and Hoshino, 1983)
