Food Processing & Preservation

Food preservation includes preventing the development of microorganisms and slowing the oxidation of fats that cause rancidity, resulting in a longer shelf life and a lower risk of food poisoning. Food protection is a major concern in the packaging industry because processed foods are easily contaminated, and a rise in contamination can rapidly spread illness. Food preservation must be combined with food production. Some preservation processes, such as the addition of food additives for preservation, cause diseases in humans. Many methods and techniques are now used in food processing and packaging to enhance food quality and shelf life, as well as to build a shield against oxygen, light, UV, and other contaminants. To enhance the Rheology, characteristics, and shelf life of foods, different ingredients and food designs are used to alternate the food products.
