Product overview

What is food grade Monoammonium Phosphate?

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.

Procurement checklist

How to source food grade Monoammonium Phosphate in bulk

Compare the offered grade, test methods and commercial terms before requesting a sample or placing an order.

Identity and quality criteria

Qualify INS 342(i), assay, pH, fluoride, arsenic, lead, chloride, sulfate and solution clarity.

Monoammonium phosphate for bakery

Provide the leavening system, flour type, process and target reaction profile for a relevant evaluation.

Quantity and order requirements

State quantity, packing, destination, target standard and document or sample requirements.

Monoammonium vs diammonium phosphate

MAP has an acidic solution while DAP has an alkaline solution; compare formula performance, not names alone.

Application screening

Food grade Monoammonium Phosphate applications

Application selection depends on destination-market permission and finished-food trials.

Leavening systems

Can contribute acid phosphate behavior in validated bakery or premix formulations.

Dough conditioning

May be evaluated for process consistency and dough handling where permitted.

Buffering

Its acidic aqueous pH can support pH control in compatible food systems.

Dry premixes

Particle form, moisture protection and blend uniformity should be confirmed during trials.

Commercial specifications

Food grade Monoammonium Phosphate reference specification

The commercial reference includes specification values and representative sample results. Example results are not the COA for a current shipment.

Acceptance criteria: Chloride 0.035% and sulfate 0.038% are reference values without defined acceptance comparators. They are not established maximum limits. Agree the required limits, analytical methods and reporting basis in the signed specification before ordering.

Technical selection

Questions to resolve before approving Monoammonium Phosphate

pH target

Confirm whether the process needs acidic MAP or the more alkaline DAP.

Analytical definitions

Define whether the chloride and sulfate values are maximum limits or another reporting criterion.

Contaminant criteria

Align elemental limits, methods and reporting units with the destination market.

Representative result

Request a current batch COA; do not approve supply only from the representative example result.

Qualification support

Product documents and quality requirements

Product documents

Request the current signed specification or TDS, SDS, test methods, representative COA and batch COA.

Food-grade selection requirements

Verify applicable food-safety, quality, Kosher, Halal and site documents for the exact grade and source.

Official identity reference

Review the FAO/JECFA ammonium dihydrogen phosphate specification, then apply destination-market rules to the exact finished food.

Storage and handling

Protect Monoammonium Phosphate in storage

EnvironmentStore in a cool, dry and well-ventilated area in accordance with the current SDS.
MoistureKeep containers tightly closed and protect packaging from water, humidity, contamination and damage.
ControlsUse food-ingredient hygiene, lot traceability and stock rotation appropriate to the supplied shelf life.
