Berkel Vacuum Sealer
What is vacuum sealing?
Food spoilage is caused by chemical reactions in food when exposed to air, temperature, humidity, the action of enzymes, the growth of micro-organisms or contamination by insects. Vacuum packing involves reducing the absolute air pressure inside the package, oxygen is removed and volatile substances are eliminated. Oxygen in the air causes food spoilage, mainly through the oxidation process, causing loss of nutritional value, flavour and all qualities. Air also contributes to the growth of most micro-organisms and causes frostbite on frozen food. Vacuum packaging extends the shelf life of many fresh foods by prevent oxidation and prevent microbial growth (bacteria and fungi).
GOODBYE BACTERIA AND FUNGI!
Fungi, yeasts and bacteria are present everywhere, but can only cause problems under certain conditions. For example, fungi do not grow in low-oxygen environments or in the absence of moisture. Bacteria, on the other hand, can multiply with or without air, depending on their nature.
These microorganisms cause noticeable changes at colour, texture and flavour which depend on time, storage temperature and, above all, the presence of air. The absence of air, which is achieved by vacuum packaging, significantly slows this spoilage. Some products such as flour and cereals may contain larvae, but vacuum packaging prevents these larvae from becoming insects and contaminating the food.
Vacuum packaging changes the way you buy and store food. Keeping food vacuum (i.e. without air) extends the life of food, whether it is stored in the pantry, fridge or freezer. Air can make food stale and rancid, make it ferment, dry out or cause freezer burn.
Vacuum packaging keeps food fresh and tasty for longer. Now you can package fresh food bought at the market or food from the garden in customised portions, even in large quantities.
Foods such as coffee, rice, flour and dried fruit last much longer if vacuum-packed. Check out the comparative table and find out how the shelf life of the most common foods changes.
*Indicative values that depend on the integrity of the packaging and on the quality characteristics of the original food. They also refer to the packaging obtained with the combination of machine - bags/rolls, containers and "original" accessories.
