1) automatic packaging machine for fruits and vegetables, vacuum packaging reduces the oxygen content of the bag, fruits and vegetables can produce carbon dioxide through anaerobic respiration, while maintaining a certain degree of humidity, this low-oxygen, high carbon dioxide, high humidity environment, can effectively reduce the transpiration of the fruit, reduce the respiration of the fruit to reduce the production of ethylene and nutrient depletion, to achieve the purpose of preservation of freshness;.
(2) for meat food, vacuum packaging machine to remove the oxygen in the bag, can inhibit the growth and development of mold and other bacteria, inhibit the decomposition and oxidation of fats and oils, control food deterioration, to achieve the purpose of preservation of freshness and quality. There are relevant reports that vacuum packaging of fresh meat, due to the continuous respiration of meat tissues, as well as the frequent activities of some microorganisms, the oxygen in the vacuum bag will be converted into carbon dioxide, and the accumulated carbon dioxide can effectively inhibit the reproduction and generation of bacillus, thus having a certain effect on the preservation of meat;.
(3) as far as other foods are concerned, the vacuum packaging machine can reduce the evaporation of water after packaging, and control the phenomenon of condensation and coagulation caused by the loss of water in food;.
(4) vacuum packaging in addition to the above functions, but also has the resistance to mechanical pressure, reduce oscillation, facilitate long-distance transportation and other advantages, so it can more effectively maintain the original color, aroma, taste, shape and nutritional value of food.
