Monopotassium phosphate in the food industry is used as food additives to stabilize and control food’s acidity and moisture. Its buffer properties allow pH value to be stabilized, the ionic strength of food to be improved, and the adhesion of water to the food holding ability to be increased. It is also widely used in the manufacture of flavoring agents, fermentation additives, baked goods, yeast food, and nutritional fortifiers.
Monopotassium phosphate effectively maintains and improves the shelf life of processed foods. It is an additive commonly found in dairy products, frozen meals, fruit juices, canned fish, cereal, soup, and vegetables. Generally speaking any processed food including fast food might contain a phosphate additive such as monopotassium phosphate.
