In addition to extracting oxygen and inhibiting the growth of microorganisms, vacuum packaging bags also prevent food oxidation, because the oil in food contains fatty acids, which can chemically react with oxygen to spoil the food. Oxygen can also make the vitamin A in the food. When vitamin B is reduced, the pigments in food can also react chemically with oxygen to darken the color of food.
