Direct product answer
Food grade monoammonium phosphate (MAP), chemically ammonium dihydrogen phosphate, is a water-soluble acidic phosphate used in suitable foods as a buffer, dough conditioner and leavening ingredient.
For procurement, “food grade” must be supported by a current source-specific specification, suitable manufacturing and quality documents, and a batch COA. Final use depends on the complete formulation, intended function and destination-market rules.
Buyer-intent guide
Use these qualification points when comparing a China supplier, manufacturer source, distributor offer, bulk quotation or sample.
Qualify INS 342(i), assay, pH, fluoride, arsenic, lead, chloride, sulfate and solution clarity.
Provide the leavening system, flour type, process and target reaction profile for a relevant evaluation.
State quantity, packing, destination, target standard and document or sample requirements.
MAP has an acidic solution while DAP has an alkaline solution; compare formula performance, not names alone.
Application screening
These are application-screening areas, not universal approvals or dosage recommendations. Confirm legal use and performance in the finished food.
Can contribute acid phosphate behavior in validated bakery or premix formulations.
May be evaluated for process consistency and dough handling where permitted.
Its acidic aqueous pH can support pH control in compatible food systems.
Particle form, moisture protection and blend uniformity should be confirmed during trials.
Supplied technical data
The attachment supplies a specification and a representative sample result. The result is reproduced for screening only and does not replace a current batch COA.
| Test item | Specification | Supplied example result |
|---|---|---|
| Assay as NH4H2PO4 | 96.0–102.0% | 98.8% |
| Fluoride | ≤ 10 ppm | 5 ppm |
| Arsenic | ≤ 3 ppm | < 3 ppm |
| Heavy metals (as Pb) | ≤ 10 ppm | < 10 ppm |
| Lead (Pb) | ≤ 4 ppm | < 4 ppm |
| Chloride | 0.035% | 0.030% |
| Sulfate | 0.038% | 0.029% |
| pH (10 g/L) | 4.3–5.0 | 4.6 |
| Clarity and color | Colorless; turbidity no greater than almost clear | Conforms |
Data note: The source table does not show inequality signs for chloride 0.035% or sulfate 0.038%. They are therefore reproduced without adding a comparator. “Heavy Mental” and “Sulfater” were normalized to “Heavy metals” and “Sulfate.” Confirm acceptance criteria and methods before contracting.
Technical selection
Confirm whether the process needs acidic MAP or the more alkaline DAP.
Resolve the missing chloride and sulfate comparators in the source sheet.
Align elemental limits, methods and reporting units with the destination market.
Request a current batch COA; do not approve supply only from the supplied example result.
Qualification support
Request the current signed specification or TDS, SDS, test methods, representative COA and batch COA.
Verify applicable food-safety, quality, Kosher, Halal and site documents for the exact grade and source.
Review the FAO/JECFA ammonium dihydrogen phosphate specification, then apply destination-market rules to the exact finished food.
Storage and handling
Buyer questions
Monoammonium Phosphate is used in suitable food processes for phosphate, buffer and leavening ingredient functions. Legal use, dosage and performance must be confirmed for the exact food and destination market.
Monoammonium Phosphate is identified here by CAS 7722-76-1 and INS 342(i). Confirm the identity and supplied form on the current specification.
Request the current signed specification, agreed test methods, representative COA and a current batch COA. Resolve every missing unit, comparator or particle-size requirement before approval.
Confirm bag type, net weight and pallet requirement. Confirm food-contact liner, palletization, marks and container loading in the quotation.
Provide the food application, target standard and critical limits, quantity, packing, destination, certificates, Incoterm and requested delivery date.
