How to use food vacuum packaging bags correctly? Precautions for using vacuum packaging bags

Food vacuum packaging bag refers to a packaging method in which products are added to an airtight packaging bag, and the air inside the bag is extracted to achieve a predetermined vacuum degree in the sealed bag. The principle is relatively simple, which uses the principle of deoxygenation to effectively prevent food from spoiling, maintain its color, aroma, taste, and nutritional value. Of course, in order to fully utilize the function of vacuum packaging bags, the first step is to master the correct usage method. So, how to use vacuum packaging bags correctly? What are the precautions for using vacuum packaging bags?

1. The influence of environmental temperature on the storage effect of food vacuum packaging.

The moisture in the air is permeable to packaging materials, and the permeability coefficient is closely related to temperature. Generally, the higher the temperature, the greater the permeability coefficient, and the more severe the penetration of packaging materials. So for food packaged in vacuum bags, it needs to be stored at low temperatures. If stored at high temperatures, it will seriously affect the permeability of the packaging bag and cause the food to spoil. Generally, vacuum packaged food should be stored at temperatures below 10 ℃.

2. Quality issues in the vacuum packaging process of food

Firstly, when vacuum packaging is heat sealed, it is important to ensure that the sealing area does not have any residue such as oil, protein, food, etc., to ensure that the seal can be fully heat sealed. When heating vacuum packaged packaging bags, the temperature and time should be strictly controlled to avoid excessive pressure inside the bag due to high temperature, which can cause the bag seal to separate or break. Secondly, vacuum packaging bags should be evacuated, especially for fresh meat and amorphous food vacuum packaging, to prevent residual gas from causing food inside the vacuum packaging bag to spoil and deteriorate.

3. Foods that are not suitable for vacuum packaging

Products that are not suitable for vacuum packaging bags, such as fragile foods, can easily be punctured or penetrated if these foods have edges and corners. So, do not use vacuum packaging for this type of food, use other packaging.
