What is vacuum sealing and how does it work?
Vacuum sealing is a method of packaging that removes air from the packaging before sealing it, creating a vacuum. This process helps to significantly reduce the amount of oxygen in the package, which slows down the deterioration of food due to oxidation and the growth of bacteria and mold. The sealing is accomplished using a vacuum sealer machine, which typically involves placing the food items in a specially designed bag and then using the machine to remove air and seal the bag tightly.
The absence of air in the sealed bag also prevents freezer burn when storing food in the freezer. By creating an airtight environment, vacuum sealing preserves the freshness, flavor, and nutritional quality of food for a much longer time than traditional storage methods. This technique is widely used for both commercial food packaging and home food preservation.
Can I vacuum seal all types of food?
In general, vacuum sealing is suitable for a wide variety of foods, including meats, cheese, fruits, vegetables, and dried goods. However, certain foods should be vacuum sealed with caution.
