One of the simplest methods for preserving food, whether it is raw materials for future cooking or cooked meals to enjoy later, is vacuum sealing. Vacuum packaging machines keep food at its best flavour and texture by reducing exposure to air and avoiding freezer burn. Dry items that can be kept fresh for a long time include cereals, nuts, cured meats, cheese, smoked salmon, coffee, and potato chips are all vacuum sealed. These machines have a stainless-steel body.
