Food grade gases are additives, which play a significant role in the preservation and food packaging processes. These gases are majorly used to grind, freeze, and package a variety of products, which include dairy & bakery items, fish & seafood, beverages, poultry products, vegetables & fruits, and prepared meals. In addition, for maintaining the quality of food, the use of food grade gases has increased in the food industry. The major gas used in food processing applications is modified atmosphere packaging (MAP), which is used to preserve minimally processed food products such as meat, fish, vegetables, and fruits. In addition, MAP prevents the spoilage of food by inhibiting microbial growth, oxidation as well as preventing discoloration and moisture loss.
