The provision of meals on a large scale to workplaces, institutions, and events: factory canteens, hospital catering, school meals, airline food, and staff restaurants. Industrial caterers produce hundreds or thousands of meals daily under tight cost and time constraints, relying on central production kitchens, cook-chill and cook-freeze systems, and strict HACCP controls. Menus must satisfy diverse dietary needs while remaining nutritious, appealing, and affordable. The sector is a major purchaser of commodity ingredients and convenience foods, and its standards influence what millions of people eat at work and school every day. Efficiency, safety, and consistency define successful operations.
