Potassium Metaphosphate Food Additive Grade

Molecular Formula：(KPO₃)n

CAS NO.: 7990-53-6

EINECS NO.: 232-212-6

Potassium Metaphosphate is a food-grade additive that is used as a sequestrant, buffering agent, and emulsifier. It is commonly found in processed foods such as canned fruits and vegetables, dairy products, and meat products.

As a sequestrant, potassium metaphosphate helps to prevent the formation of unwanted compounds in food, such as metal ions that can cause oxidation or spoilage. It also helps to stabilize the pH of foods, acting as a buffering agent to maintain a consistent acidity level.

Potassium metaphosphate is also used as an emulsifier, helping to mix ingredients that would otherwise separate, such as oil and water. This makes it useful in products like salad dressings and mayonnaise.

Overall, potassium metaphosphate is considered safe for consumption in small amounts and is regulated by the Food and Drug Administration (FDA) as a food additive.

Potassium carbonate is a food additive that is used as a leavening agent in baked goods. It is a white, odorless powder that is soluble in water. Potassium carbonate is also used to adjust the pH of certain foods, such as cocoa powder and coffee.

In baking, potassium carbonate reacts with acids in the dough to produce carbon dioxide gas, which causes the dough to rise. It is commonly used in traditional Chinese steamed buns and some European breads, such as German pretzels.

Potassium carbonate is generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA) when used in accordance with good manufacturing practices. However, it may cause skin and eye irritation, so proper handling and protective equipment should be used when handling the powder.

Overall, potassium carbonate is a useful food ingredient that helps to improve the texture and flavor of baked goods and other foods.
