Frequently Asked Questions (FAQs)-Disodium Phosphate (DSP) 

What is Disodium Phosphate Food Grade (DSP)?

Disodium Phosphate Food Grade (DSP) is a sodium salt of phosphoric acid with formula Na₂HPO₄ and CAS 7558-79-4, used as an emulsifier and buffer in foods. It’s a white, water-soluble powder that stabilizes pH and enhances texture in dairy and baked products.

How is DSP used in cheese production?

Add DSP at 2-4% during blending to emulsify fats and proteins, promoting meltability and preventing oil separation. It reacts with casein for a creamy mouthfeel in slices and sauces.

Is DSP safe for food fortification?

Yes, DSP is FDA GRAS and approved by Codex Alimentarius up to 70 mg/kg phosphorus equivalent, with excellent bioavailability and no adverse effects at regulated levels.

What is the shelf life of Disodium Phosphate(DSP) ?

Stored in dry, airtight conditions at ambient temperature, DSP maintains stability for 2-3 years, with no significant moisture absorption or potency loss.

Can DSP be combined with other phosphates?

DSP works synergistically with monocalcium phosphate in leavening systems but should be evaluated with acidic ingredients to avoid over-alkalinity; it’s stable in multi-salt blends.

Does DSP influence the taste of products?

With its neutral flavor and mild alkalinity, DSP has negligible impact on taste when used within guidelines, preserving the natural profile of fruits, meats, and grains.

What packaging options are provided for Disodium Phosphate(DSP) ?

Choices include 25kg multi-wall bags, 25kg fiber drums, and 500kg supersacks, all lined for humidity protection and compliant with food transport regulations.
