The Mechanism of Vacuum Packaging Machine
The main role of vacuum packaging is to remove oxygen, in order to help prevent food deterioration, the principle is relatively simple, due to food mold rot deterioration caused by the activities of microorganisms, and most micro-organisms (such as mold and yeast) is the need for oxygen
Vacuum deaerator In addition to inhibiting the growth and reproduction of microorganisms, another important function is to prevent the oxidation of food, because the fat food contains a large number of unsaturated fatty acids, the role of oxygen and oxidation, so that food taste, deterioration, in addition,
(Note: Vacuum packaging can not inhibit the growth of anaerobic bacteria and enzyme reactions caused by deterioration and discoloration of food, and therefore need to be combined with other auxiliary methods, such as refrigeration, quick freezing, dehydration, high temperature sterilization, irradiation sterilization, microwave sterilization, salt
Experiments show that when the oxygen concentration in the bag is less than or equal to 1%, the growth and reproduction speed of the microorganism decreases sharply. When the oxygen concentration is less than or equal to 0.5%, most microorganisms will be inhibited and stop breeding.
, And vacuum packaging is the use of this principle, the bags and food cells within the oxygen removed, so that the loss of microbial survival of the environment.
