Sodium dihydrogen orthophosphate, also known as monosodium phosphate or sodium phosphate monobasic, is a chemical compound with the molecular formula NaH2PO4. It is composed of sodium cations (Na+) and dihydrogen phosphate anions (H2PO4-).  Curiosity piques as you ponder its capabilities, so let us embark on this exploration together, discovering what it can truly do.

Functions

Sodium Dihydrogen OrthophosphateEmulsifier: Sodium dihydrogen orthophosphate helps stabilize emulsions by promoting the mixing of water and oil-based ingredients. It is used in salad dressings, sauces, and processed meat products.

Nutrient Enhancer: Sodium dihydrogen orthophosphate serves as a nutrient enhancer by providing a source of phosphorus, which is an essential mineral for the human body. It is added to sports drinks, nutritional supplements, and fortified food products.

Texture Modifier: In certain food applications, it can improve the texture and mouthfeel of products. It is used in processed cheeses, processed meats, and bakery items.

Leavening Agent: Sodium dihydrogen orthophosphate is utilized as a leavening agent in baked goods. When combined with a baking soda (sodium bicarbonate), it helps dough or batter rise during baking.

Sequestrant: It acts as a sequestrant, preventing undesirable interactions between metal ions and food components, thereby enhancing product quality and stability. It is used in canned seafood, processed meats, and dairy products.

Anticaking Agent: Sodium dihydrogen orthophosphate is added to powdered food products to prevent clumping or caking. It enhances the flowability and consistency of products like powdered beverages, spices, and powdered cheeses.

Acidulant: It can be used as an acidulant to impart a tangy or acidic taste to certain food products. It is employed in carbonated beverages, fruit-flavored drinks, and gelatin desserts.

Stabilizer: It acts as a stabilizer (E339), helping to maintain the desired texture and prevent separation in food products. It is used in salad dressings, creamy desserts, and dairy-based products.
