Vacuum Food Sealers

Vacuum Food Sealers

Vacuum food sealers have revolutionized the food storage industry.  These machines are used in both the manufacturing process and in the home to preserve foods for greater periods of time.  By prolonging the freshness of food items, vacuum food sealers have made a variety of foods available to all areas of the country.  Fresh seafood is now available in the midwest areas because fishermen are able to vacuum seal their catch immediately after pulling it out of the sea.  They also make it possible for individuals to buy food in bulk, thus saving money, and repackaging into smaller amounts using the vacuum sealers at home.  Vacuum sealing foods prevents the growth of microorganism, prolonging the decomposition of foods.

Benefits of Vacuuming sealing Food

Vacuum sealing foods extends the freshness of the food.  By removing the atmospheric oxygen, vacuum sealing prevents the growth of aerobic micro-organisms which cause food spoilage.  Vacuum sealing also prevents valuable moisture in some foods from evaporating.  In other foods, it prevents moisture from getting in and spoiling the dry goods.

Oxygen exposure is responsible for the majority of food spoilage.  When oxygen is present, the food begins to break down on the molecular level.  Most microorganisms that spoil food require oxygen to function and grow.  By removing the oxygen from the package, these microorganisms are prevented from growing and causing food spoilage.

Freezer burn is also caused by presence of air, where water present in the food sublimates (turns from a solid to a gas), then later condences as ice crystals on the food, destroying the texture. A vacuum can greatly reduce this phenomenon, increasing the life of foods in freezers. Some products also benefit from a gas-purge cycle in order to reduce the PPM levels of oxygen to a very minimal number. Vacuum packaging foods is a terrific way to effectively suspend decay that would occur in an ambient environment by managing destructive gasses within the sealed container.

Applications for Vacuum Food Sealers

Vacuum sealers are used in the manufacturing process to ensure freshness of the food.  Vacuum sealing is commonly used in the production of dry goods.  This sealing process makes the long-term storage of these foods possible.  It is believed that vacuum sealers were first commercially used in packaging coffee.  Vacuum sealers in manufacturing use a variety of packaging containers including flexible thermoform pouches, glass and metal containers, plastics, cans, bottles, and canisters.  Vacuuming sealing has made it possible for food manufacturing companies to ship their products over greater distances and still ensure freshness.

Vacuum food sealers are also available for home use.  There are many styles and models available.  These also use a variety of containment systems.  Some models have attachments making it possible to vacuum seal bags, bottles, mason jars, and other containers.  By being available for home use, families are able to save money spent on food.  Food is bought in bulk, typically the cheaper way to buy food, and broken down into smaller sizes in the home.  The smaller portions are then vacuumed sealed, prolonging the shelf-life.  Vacuum sealers are used in sealing dry-goods for long term storage.  They can also be used for short-term storage of fresh produce, meats, and liquids.

Small local food producing businesses are able to expand their customer base because vacuum food storage is available.  What was once a local market only, due to freshness concerns, is now a global one.  Also, foods that are indigenous to a particular region, such as tropical fruit, are now available to other areas.  Vacuum food sealers are a great asset to the growing global food market, for both the manufacturer and the consumer.
