Choosing the right bag for packaging
For a successful packaging operation with a vacuum machine, it is necessary to have bags on hand. But not just any bags. Most commercially available machines come with a set of these packages. However, there may be times when you run out and need to purchase more. In this case, you should consider the size of the food to be preserved, as well as its nature. You will insert the food into the bag and then adjust the edges. Next comes the sealing phase.
The sealing
Once the food is placed in the bag and its edges are straightened, you proceed to remove the air inside. This helps to prevent, in most cases, the multiplication of bacteria responsible for the rapid degradation of the product. It is preferable that this operation is done in a very short time. You will then proceed to seal the opening. This should also be kept clean.
Labeling the packaging
To avoid being caught off guard by the product’s expiration date, it is important to label it once the sealing is done. This step involves writing certain key information on the packaging. This includes the vacuum sealing date of the food and the estimated expiration date. The name of the food as well as its storage conditions should also be included. This will help you manage your supplies effectively over time, thereby saving in the long run.
Once all these precautions are taken, proceed with the packaging. The recommended temperature for this operation is between 0 and 4 ° Celsius. For packaging, you can use cold water or a cold chamber.
