Benefits of Preserving Food with a Vacuum Sealer
Vacuum sealing was originally used by food packing companies in the 1940's as a way to save money. The technique prevented spoilage and prolong the shelf life of food products, especially ones transported over long distances. It not only hindered the growth of bacteria and mold, but it also kept food fresh and prevented freezer burn. Vacuum sealing is still used for the exact same purpose today. It's a convenient and economical way for households to preserve, protect, and store their food.

How Vacuum Sealers Preserve Food
Vacuum sealers preserve food primarily by inhibiting the growth of mold, fungus, and spoilage bacteria such as mesophiles, psychrotrophs, thermophiles, and psychrophiles. When these bacteria reproduce and multiply, they break down organic enzymes, such as chlorophyll in plants and iron containing pigments in protein, and leave behind ammonia, amines, sulfides, and organic acid buildups that cause discoloration, rancid odors, and slimy residues. They not only ruin the taste, appearance, and texture of your food, but also cause serious illness if eaten. Fortunately, these types of bacteria are obligate bacteria, which means they require oxygen to metabolize food and reproduce. Vacuums sealing food deprives them of oxygen, which halts their growth cycle and renders them inert. Oxygen deprivation has the same effect on mold and fungal spores. Without oxygen, they can't grow and consume your food.
