Uses
- Food Industry
Used as additive in the coffee creamers substitute and as nutrient in various powdered materials (stabilizer (emulsifier) in non-dairy creamers, bodybuilding drinks). Its function is to prevent protein coagulation, and also to prevent its precipitation. It is a humectant. Also included in foods where low Sodium is specified, like low Sodium cheeses. It helps control the pH in food processing applications.
As a food additive, Dipotassium phosphate is on the FDA's Generally recognized as safe, or GRAS, list of substances. It is used in non-dairy creamers to prevent coagulation
- Pharmaceutical Industry:
Used as nutrient in microorganism cultures to produce antibiotics, and as a buffering agent in certain pharmaceuticals.
- General:
Put into antifreeze solutions as a buffer and sequestrate, used as a dispersion medium in liquid detergents and as an additive in cheese processes. It's an ingredient in non-toxic antifreeze.
Used as a high efficient, compound fertilizer preparation for special purposes and as additive in the paper industry.
