Monoammonium Phosphate
Monoammonium Phosphate is a crystalline salt of formula NH₄H₂PO₄ that functions as a yeast nutrient, mineral acid source, and minor leavening acid in food applications.
The compound, often shortened to MAP, supplies bioavailable nitrogen and phosphorus to fermenting yeast and contributes a mild acidic note to chemical leavening systems.
We source bulk Monoammonium Phosphate from top China manufacturers for our partners, working with several of them. The manufacturers are in Sichuan, Hubei and Jiangsu. For this ingredient the minimum order is 500 kg and a 20-foot container takes 24 MT, and a smaller requirement can ship in a combined container with other ingredients.
Please send the grade you need, the volume and your destination port, and we will come back with a solution and a price.

Common Markets Grades
Monoammonium Phosphate sells in food, fermentation and technical grades.
Food grade conforms to FCC and JECFA monographs with assay above 98 percent. Particle size ranges from fine powder for dry blending to granular for direct addition to mash tanks.
Fermentation grade is the dominant volume grade for brewing, winemaking, and bioethanol. It is produced with controlled heavy metal limits and low arsenic content to meet beverage industry expectations.
Technical grade serves the agricultural fertilizer, fire retardant, and metal treatment industries where food purity is not required.
Applications
- Yeast nutrient in beer brewing, wine fermentation, sake, and cider production
- Nitrogen and phosphorus supplement in industrial bioethanol fermentation
- Component of yeast extract and yeast cream production media
- Minor leavening acid in self rising flour and pancake mixes
- Buffering agent in dairy beverages and processed cheese
- Mineral fortification in nutritional and sports drink powders
- pH adjustment in soft drink syrups
- Plant tissue culture media and hydroponic nutrient solutions
- Fire retardant treatment for wood, paper, and natural textiles
- Component of high analysis NPK fertilizer blends

How We Help Source Monoammonium Phosphate
Direct Factory Sourcing
We run the whole process: selecting the manufacturer from the top Chinese food ingredient producers, negotiating the price, verifying quality, and coordinating the logistics. You deal with us instead of with several factories at once.
Original Packaging and Documents from the Manufacturer
The manufacturer sends your Monoammonium Phosphate out of its own factory in the original packing, through to your destination port. The COA, COO, MSDS, TDS and any certifications reach you from the manufacturer as well.
Free Samples and Lead Time
We send 100 to 500 g free for your own laboratory to test and you cover only the courier, usually within 2 to 3 working days. ETD is usually within 7 to 15 days once the order is confirmed, and we check that date against the factory's own manufacturing schedule before we give it to you.
Combined Shipment
We can load Monoammonium Phosphate together with other ingredients such as Sodium Acid Pyrophosphate, Monocalcium Phosphate and Diammonium Phosphate into one 20' FCL. If your quantity is small, we can also ship LCL.
Regulatory Status
Monoammonium Phosphate is approved as a food additive in major regulatory regions.
The European Union lists ammonium phosphates collectively under E342, with E342(i) referring to the monoammonium salt. Regulation 1333/2008 permits it as an acidity regulator, raising agent, and emulsifying salt, and governs its use.
The U.S. Food and Drug Administration recognises the salt as GRAS under 21 CFR 184.1141a as a dough strengthener, leavening agent, and yeast nutrient.
JECFA has evaluated ammonium phosphates and placed them in the acceptable group without numerical restriction when used in accordance with good manufacturing practice. Specifications appear in the FCC and the EU additive monograph collection.
Manufacturing Process
Industrial Monoammonium Phosphate is made by reacting phosphoric acid with anhydrous or aqueous ammonia at a molar ratio of one to one.
The reaction H₃PO₄ + NH₃ → NH₄H₂PO₄ is strongly exothermic and runs in stirred reactors with controlled cooling. The hot slurry is fed to a granulator or to a vacuum crystalliser depending on the target product form.
Food grade material is recrystallised once or twice from purified phosphoric acid to remove fluoride and trace metals. The final crystals are dried, screened, and packed under low humidity.
