The chart below illustrates the efficacy of the three most widely used methods of food preservation.

 

Packaging Method Results Benefits
Oxygen Absorbers Reduces and maintains oxygen content in packaging to below 0.01%

Eliminates aerobics microbial growth and oxidative chemical reactions in packaging

Vacuum & Back Flush Achieves as little as 0.1% residual oxygen Controls aerobic microbial growth temporarily*
Gas Flushing Achieves approximately 0.5% to 5% residual oxygen Provides some control of aerobic microbial growth*

 

*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)
