About This Product
Sodium dihydrogen phosphate, also called monosodium phosphate or MSP, has the formula NaH2PO4, CAS number 7558-80-7 and the European additive number E339(i). It is supplied anhydrous or hydrated as a white crystalline powder, very soluble in water, giving an acidic solution around pH 4.5.
It is the acidic member of the sodium phosphate series and is normally used in combination with the alkaline disodium salt. Blending the two in different proportions produces a buffer that can hold a product at any chosen pH across a broad band and keep it there, which is the basis of its use in dairy, beverages and processed foods where pH drift would affect stability, texture or taste. On its own it acts as a mild acidulant and as a sequestrant for calcium and magnesium. In meat and poultry processing, phosphates raise pH slightly away from the isoelectric point of the muscle proteins, which opens the protein structure so it binds and retains more water during cooking, improving yield and juiciness. It also serves as a leavening acid component and as an emulsifying salt in cheese products.
It is used in meat and poultry brines, processed cheese, dairy and evaporated milk, beverages, bakery and as a general acidity regulator.
Bio Green Foods supplies food-grade MSP to specification on assay, pH, loss on drying, water-insoluble matter, fluoride, arsenic and heavy metals.
