What is the knowledge of using food vacuum packaging bags? Pay attention to the impact of storage environment temperature on the vacuum packaging effect. The permeability coefficient of various gases in the air to packaging materials is closely related to temperature. In general, as the temperature increases, the permeability coefficient of packaging materials also correspondingly increases, and the gas permeability to the film also increases.
Therefore, vacuum packaged food should be stored at low temperatures. If stored at higher temperatures, it will undergo short-term metamorphosis due to increased air permeability. Generally, vacuum packaged food should be stored and circulated below ten degrees Celsius. The operational quality of the vacuum packaging process. When vacuum packaging is heat sealed.
Attention should be paid to the inner surface of the packaging material not sticking any residue such as oil or protein under the sealing area to ensure the quality of the sealing. For the heating and sterilization treatment of vacuum packaging, the sterilization temperature and time should be strictly controlled to avoid the internal pressure increase of the packaging caused by high temperature, which can cause the packaging material to break and the sealing part to peel off.
Or the sterilization effect cannot be achieved due to poor temperature. In addition, during vacuum packaging, it is necessary to fully extract air, and special attention should be paid to the vacuum packaging of fresh meat and amorphous food. Air pockets should not be left to prevent the proliferation of residual microorganisms during the shelf life caused by residual air, which can cause food erosion and transformation.
