Application of modified atmosphere packaging 2
Modified atmosphere packaging of fresh meat and poultry
The modified atmosphere packaging of raw pork, sheep, and beef meat must maintain the original red color of the fresh meat and can be preserved and preserved. The atmosphere of the modified atmosphere packaging is composed of O2 and CO, and the gas composition is different according to the type of meat.In the modified atmosphere packaging of meat, the use of high concentration of 0 can keep the fresh meat brighter and more vivid, and the meat quality is lavender under an oxygen-deficient environment. For example, with fresh gas such as CO2, the meat color is lavender, and the preservation period Up to about 30 days.
Fresh meat packaging materials also require the use of composite plastic rice packaging materials with high gas barrier properties.
In order to avoid loss of water due to packaging problems or raw poultry, if high concentrations of carbon dioxide are used, the gas / product ratio should be increased accordingly. When packaging does not become a problem (using superior packaging), 100% concentration of carbon dioxide is recommended. When retail packaging is used, nitrogen is also used as an internal inert gas.
