Abstract
A CO-containing modified atmosphere packaging (MAP) gas is generated from a processing gas including CO2 and an optional inert gas by applying an electric field under conditions sufficient to generate non-thermal plasma. The fresh appearance of meat or seafood is maintained for a longer time by storing them in a container with the MAP gas.
Claims28
A method of color preservation of meat or seafood, comprising the steps of:
- storing meat or seafood in a sealed container containing a modified atmosphere packaging gas comprising CO2 and CO;
- and
- before or simultaneous with said step of storing, the CO2 and CO of the modified atmosphere packaging gas are produced by applying an electric field to a processing gas comprising CO2 under conditions sufficient to generate non-thermal plasma comprising CO2 and CO, wherein the processing gas has an oxygen concentration of less than 10% vol/vol O2 and a CO2 concentration of at least 5% vol/vol.
