MAP Technology Food Packaging Gas Packaging

Precautions for using modified atmosphere packaging (1) Processing of fresh meat before packaging. If the pork is cooled at 0℃-4℃ for 24h after slaughtering, the acid excretion process will occur after the ATP stops moving. The chiled meat treated in this way has far better nutrition and taste than quick-frozen meat and hot fresh meat. In addition, in order to ensure the preservation effect of modified atmosphere packaging, it is also necessary to control the hygienic indicators of fresh meat before packaging to prevent microbial contamination.  (2) Selection of packaging materials. Fresh Meat MAP Trays should use packaging materials with good barrier properties to prevent gas leakage in the packaging and at the same time prevent the infiltration of oxygen in the atmosphere. Composite packaging films such as PET, PP, PA, and PVDC are usually used as the base material. To measure the gas barrier properties of plastic films, it is generally expressed by the air permeabi…
