Monosodium Phosphate (MSP) is a high-purity acidic sodium orthophosphate additive, available in two forms: anhydrous and monohydrate. It features good water solubility, stable chemical properties, and wide compatibility with food and feed ingredients.

Its primary function is pH adjustment and acidification. As an acidic phosphate, MSP lowers and controls the pH value in food and beverage systems, creates the required acidic environment for processing, improves microbial stability, and supports gelling, emulsification and protein functionality in formulations. It also acts as a sequestrant to bind metal ions, reducing oxidation, discoloration and turbidity. In dairy and processed cheese, it works with other phosphates as an emulsifying salt to optimize melting performance and texture. It can also serve as a phosphorus nutrient fortifier for food and animal feed.

Anhydrous MSP and monohydrate MSP deliver identical functional performance. The core difference is crystal water content. Anhydrous MSP contains no crystal water, which is suitable for low-moisture formulations that are sensitive to extra water. Monohydrate MSP carries one molecule of crystal water, offering cost-effective performance for most regular food and feed production without strict low-moisture requirements.

MSP is widely applied in beverages, dairy products, processed cheese, canned foods, baked goods, meat products and animal feed.

Character

Monosodium Phosphate is supplied in anhydrous and monohydrate crystalline forms. Both variants are white, odorless, free-flowing solids with stable chemical properties under normal storage conditions. Both dissolve quickly in water to form acidic aqueous solutions.

Anhydrous MSP has no crystal water and low inherent moisture. It is selected for formulations with strict limits on total water content, avoiding unwanted moisture interference in low-moisture powder systems. Monohydrate MSP contains crystal water, providing stable performance and better economy for general food and feed processing.

Both anhydrous and monohydrate grades meet corresponding global safety specifications for food grade and feed grade. They have low heavy metal and impurity content, compatible with most raw materials and will not change the original flavor of finished products.

Main Functions

1.pH Adjuster & Acidulant (Core Function) Lower and regulate the pH of food and beverage systems, establish stable acidic conditions, inhibit microbial growth, extend shelf life, and assist gelling and protein texture control.

2.Sequestrant Chelate calcium, magnesium and other metal ions, reduce oxidation, discoloration and cloudiness in beverages and canned products.

3.Emulsifying Salt Used together with other phosphates in processed cheese to promote protein dispersion and improve melting texture.

4.Phosphorus Nutrient Fortifier Supplement phosphorus nutrition in food and animal feed formulations.

Applications

1.Beverages (Core Application) Adjust acidity and stabilize the pH of fruit drinks, functional drinks and carbonated beverages, control flavor and prevent turbidity and precipitation.

2.Dairy & Processed Cheese Work as emulsifying salt and pH regulator to optimize melting property and texture of processed cheese and dairy drinks.

3.Canned Food & Meat Products Control acidity, chelate metal ions, protect color and extend shelf life of canned goods and processed meat.

4.Baked Goods Adjust dough pH, optimize leavening reaction and improve finished product texture.

5.Animal Feed Act as phosphorus nutritional additive for livestock and poultry, promoting bone development and growth.
