Sodium Acid Pyrophosphate (SAPP) Supplier in Malaysia
- Also known as
- SAPP
- Disodium Pyrophosphate
- Disodium Dihydrogen Pyrophosphate
- Disodium Diphosphate
Sodium acid pyrophosphate supplier for bakery, food-processing and industrial buyers in Malaysia. Traded as SAPP, disodium pyrophosphate and disodium dihydrogen pyrophosphate, this white powder or granule has formula Na2H2P2O7 and CAS 7758-16-9. It dissolves to an acidic solution, and food-grade material is the additive E450(i).
This is the acid pyrophosphate, not the neutral-to-alkaline tetrasodium salt. That acidity is what makes it a chemical leavening acid, and the grade axis is reaction rate: slow, medium and fast-acting types release different proportions of carbon dioxide at mixing and in the oven. Technical grade is also available for industrial sequestrant duties.
Bakery formulators use sodium acid pyrophosphate in baking powder, self-raising flour, cake and doughnut mixes and refrigerated dough. Potato processors use its iron-chelating action to limit after-cooking darkening, and canners use it as a struvite inhibitor in seafood. Cleaning and metal-treatment formulations take the technical grade as a sequestrant.
Send the grade, reaction rate, application, target specification, quantity and delivery location with your enquiry. Availability, packing, documentation and delivery timing are confirmed with the quotation. Supply is subject to applicable requirements.

Sodium Acid Pyrophosphate grades and forms
We supply several forms to suit different formulating and dosing setups. If you need a size that is not listed, ask us.
| Grade | Form | Assay | Typical use | Packing |
|---|---|---|---|---|
| Food grade SAPP, slow-acting rate | white powder | — | Leavening acid for doughnut, cake and refrigerated dough systems that need most of the gas released in the oven rather than during mixing. | Confirm the required pack format with the quotation. |
| Food grade SAPP, medium-acting rate | white powder | — | General-purpose leavening acid for baking powder, self-raising flour and mixed bakery lines where dough and bake-stage release are balanced. | Confirm the required pack format with the quotation. |
| Food grade SAPP, fast-acting rate | white powder or granules | — | Faster gas release during mixing and holding, used where batter aeration is needed early in the process. | Confirm the required pack format with the quotation. |
| Food grade SAPP for potato and seafood processing | white powder | — | Iron chelation to limit after-cooking darkening in potato products, and struvite crystal control in canned seafood. | Confirm the required pack format with the quotation. |
| Technical grade SAPP | white powder or granules | — | Sequestrant and process additive in industrial cleaning and metal-treatment formulations where a food-additive specification is not required. | Confirm the required pack format with the quotation. |

Sodium Acid Pyrophosphate applications
Safety and handling
Store sealed in a cool, dry place and protect from moisture, which cakes the powder and can shift reaction performance. Control dust during handling and keep it away from strong alkalis. Use gloves and eye protection and rinse with water on contact. Follow the safety information issued for the quoted grade.
Common questions about sodium acid pyrophosphate
Is SAPP the same as sodium acid pyrophosphate?
Yes. SAPP is the trade abbreviation for sodium acid pyrophosphate, also correctly called disodium pyrophosphate or disodium dihydrogen pyrophosphate (Na2H2P2O7, CAS 7758-16-9). Food-grade material is the additive E450(i).
What is the difference between sodium acid pyrophosphate and tetrasodium pyrophosphate?
They are two different salts of pyrophosphoric acid. Sodium acid pyrophosphate is the acid salt (Na2H2P2O7) and dissolves to an acidic solution, which is why it works as a leavening acid. Tetrasodium pyrophosphate (Na4P2O7) is neutral to alkaline and is used as an emulsifying salt and detergent builder. Order each by name, because swapping them changes the pH and the leavening behaviour.
Which SAPP reaction rate should I order?
Reaction rate is the grade axis a baker chooses on. Slower-acting types hold most of the gas release for the oven, which suits doughnuts, cakes and refrigerated dough; faster types release earlier during mixing and holding. Send the process and the rate your formulation is built around so the correct commercial type can be matched.
What is sodium acid pyrophosphate used for outside baking?
It chelates iron, so potato processors use it to limit after-cooking darkening in chips and other potato products. It is also used as a struvite inhibitor in canned seafood, in processed meat and seafood systems, and as a sequestrant in industrial cleaning and metal-treatment formulations.
How does SAPP compare with other leavening acids?
Formulators cross-shop SAPP against monocalcium phosphate and sodium aluminium phosphate. Those are separate products with their own release profiles, so the comparison is about timing of gas release, residual flavour and cost rather than a straight swap. Describe the bake profile you need and the requirement can be discussed against the SAPP rates.
What details are needed for a sodium acid pyrophosphate price enquiry?
Provide the grade, the reaction rate, the application, target specification, quantity and delivery location. Mention preferred packing and any documents your process requires so the quotation covers the full requirement.
