Why Vacuum Packaging Machines Dominate the Food Industry？

With the development of packaging technology, automated equipment has also been widely used in the packaging industry, such as automatic packaging machines. In the food industry, many enterprises have introduced vacuum packaging machines. Why are vacuum packaging machines so popular?

For fruits and vegetables, vacuum packaging reduces the oxygen content inside the bag, allowing them to undergo anaerobic respiration to produce carbon dioxide while maintaining a certain level of humidity. This low-oxygen, high-carbon dioxide, and high-humidity environment can effectively reduce the transpiration of fruits and vegetables, lower their respiration, decrease the generation of ethylene, and reduce nutrient consumption, thereby achieving the purpose of preservation.

For meat products, vacuum packaging machines can remove oxygen from the packaging bags, which can inhibit the growth and development of mold and other bacteria, as well as the decomposition and oxidation of oils, control food spoilage, and achieve the purpose of preservation and quality maintenance. There are relevant reports that for vacuum-packed fresh meat, due to the continuous respiration of the meat tissue and the frequent activities of some microorganisms, the oxygen in the vacuum bag is converted into carbon dioxide. The accumulated carbon dioxide can effectively inhibit the reproduction and generation of Bacillus, thereby playing a certain role in meat preservation.

3. As for other foods, vacuum packaging machines can reduce water evaporation after packaging and control the coagulation and solidification caused by water loss in food.

In addition to the above-mentioned functions, vacuum packaging also has the advantages of resisting mechanical pressure, reducing vibration, and facilitating long-distance transportation. Therefore, it can more effectively preserve the original color, aroma, taste, shape and nutritional value of food.
