Food gas, often referred to as modified atmosphere packaging (MAP) or food-grade gas, consists of high-purity gases used to extend the shelf life of food, maintain freshness, and protect products during transport. Unlike industrial gases, food-grade versions must meet strict regulatory standards for purity to ensure they don't introduce contaminants into the food supply.
History: The pioneers of food gas developed the foundation for modern preservation through four key milestones:1767 (Joseph Priestley): Invented artificial carbonation by infusing water with $CO_2$.1821 (Jacques Étienne Bérard): Proved that lowering oxygen levels delays fruit ripening.1927 (Kidd & West): Conducted the first rigorous scientific studies on controlled atmosphere storage for produce.1930s (Killefer et al.): Demonstrated that high $CO_2$ concentrations could effectively double the shelf life of fresh meat.
