Product Description

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.

ECHEMI Editorial Reference

Sodium dihydrogenphosphate monohydrate is a hydrate that is the monohydrate form of sodium dihydrogenphosphate. It contains a sodium dihydrogenphosphate.
Sodium Phosphate Monobasic Monohydrate is a reagent with very high buffering capacity widely used in molecular biology, biochemistry and chromatography. it can be used as a buffer to adjust pH. In medicine, it is sometimes used as a stimulant laxative before certain operations and medical procedures. Sodium Phosphate Monobasic Monohydrate is often used in foods and in water treatment. It is used as sequestrant, emulsifier, mordant in dyeing, reagent and buffer in foods and analytical chemistry. It is applied as a fireproofing agent and for weighting silk in tanning. It is employed in manufacturing of enamels, ceramics, detergents, boiler compounds, in soldering and brazing instead of borax.Monobasic sodium phosphate is used in baking powders, acid cleansers, electroplating, as a dry acidulant, and in treating boiler water.
Anhydrous salt: white crystalline powder; slightly hygroscopic; forms sodium acid pyrophosphate, Na2H2P2O7 on heating above 225°C and sodium metaphosphate (NaPO3)n at about 350 to 400°C; very soluble in water, aqueous solution acidic.Monohydrate: white orthorhombic crystals or granules; density 2.04 g/cm3 ; loses its water of crystallization at 100°C; very soluble in water, pH of 1% solution 4.5; insoluble in alcohol.Dihydrate: large transparent crystals; orthorhombic bisphenoidal structure; density 1.915 g/cm 3 ; decomposes at 60°C; very soluble in water; insoluble in alcohol.
The USP 32 states that monobasic sodium phosphate contains one or two molecules of water of hydration or is anhydrous.The hydrated forms of monobasic sodium phosphate occur as odorless, colorless or white, slightly deliquescent crystals. The anhydrous form occurs as a white crystalline powder or granules.
Useful in conjuction with sodium phosphate, dibasic (Cat. No. 567550) in the preparation of biological buffers(absorbance: ≤0.01 at 260 nm and 280 nm).

Our Quality

As a professional ingredient supplier, we do not operate manufacturing facilities. Instead, we build robust quality‑assurance workflows across our whole supply chain to safeguard consistent product performance for every shipment

Strict Supplier Due‑Diligence

Before entering any partnership, we carry out on-site factory visits and assess industry reputation, followed by multi-stage qualification reviews. We validate production qualifications, export track records, quality management systems and complete certification packages. New suppliers must pass sample evaluation, and only fully vetted top-tier factories are admitted to our approved supplier pool

Batch‑by‑batch Document Verification

For every order, we cross‑check factory‑issued test documents against agreed specifications including FCC, USP, EP, AJI, CP or your customized requirements. We will not forward documents to customers until key indicators are fully aligned with specifications. This step avoids inconsistent or mismatched documentation common in raw‑material trade.

Independent Third‑party Testing Coordination

Upon client request, we can arrange independent laboratory inspections from recognized third‑party institutions. We manage sample delivery, test protocol communication and report follow‑up to support your market compliance needs.

Quality Closure & Continuous Improvement

We keep traceable records for all delivered batches. If any quality concern arises, we act as your single point‑of‑contact to trace root causes with source factories, drive corrective actions and deliver practical resolution plans. Client feedback is systematically collected to optimize our supplier management and document‑review procedures.
