What is vacuum sealing and how does it work?
Vacuum sealing is a method of food preservation that removes air from a package before sealing it shut. This process helps to maintain the freshness of fruits and vegetables by significantly lowering the oxygen levels inside the packaging, which slows down the growth of bacteria and molds that can lead to spoilage. The vacuum sealing process uses a machine that seals the bag tightly around the food, creating an airtight environment.
The removal of air also helps to diminish oxidation, which can cause changes in flavor, color, and texture in fruits and vegetables. By creating a vacuum-sealed environment, nutrients are preserved for a longer duration, and you can store your produce for extended periods without compromising quality.
What fruits and vegetables are best suited for vacuum sealing?
Most fruits and vegetables can be vacuum sealed, but some are better suited for this method than others.
