Mono Ammonium Phosphate (MAP) Food Grade from Wong Khama is a white crystalline compound with the chemical formula NH4H2PO4 and CAS number 7722-76-1. It is supplied in 25 kg double-bag packaging, with an inner layer and an outer woven polypropylene bag, designed for bulk transport and storage stability. The product meets food-grade purity standards, making it suitable for use as a fermentation agent, nutrient supplement, and buffering agent in food and beverage production.
This MAP grade is composed of ammonium dihydrogen phosphate, offering a balanced ratio of nitrogen and phosphorus that supports controlled fermentation and microbial growth. Typical food-grade MAP contains over 99% purity, with trace heavy metals like lead and arsenic held below 10 ppm, a standard threshold for food additives. The compound is fully soluble in water, ensuring rapid dissolution in production processes, and is non-hygroscopic under normal storage conditions, which prevents caking in bulk handling.
Primary applications include yeast production for bakery and brewing industries, where it acts as a nutrient source to enhance fermentation efficiency. Aquafeed manufacturers also utilise MAP as a phosphorus supplement to improve growth rates in fish and crustaceans. Importers should confirm the exact purity and heavy metal content with the supplier, as these directly impact compliance with food safety regulations in the destination market. Bulk shipments are typically palletised for containerised transport, with incoterms and payment terms negotiated per order.

Before placing an order for Mono Ammonium Phosphate (MAP) Food Grade from Wong Khama, verify the product’s purity and heavy metal content against your market’s regulatory standards, such as the EU’s Regulation (EC) No 2074/2005 or the FDA’s food additive specifications. Request a recent Certificate of Analysis (COA) and confirm whether the supplier can provide additional documentation, such as a Material Safety Data Sheet (MSDS) or allergen statements, which are critical for food-grade materials.
Logistics for MAP shipments from China typically involve containerised transport, with Incoterms such as FOB or CIF offered by default. Confirm whether Wong Khama can accommodate FCL (Full Container Load) or LCL (Less than Container Load) options, as well as the preferred port of loading, which is often Guangzhou or Shanghai. Lead times may vary between 15 to 30 days depending on production schedules and shipping routes, so clarify these early in negotiations.
Quality checks for MAP should include testing for purity, solubility, and heavy metal content upon receipt. For food-grade applications, third-party laboratory testing is advisable to ensure compliance with local regulations. Inspection at the loading port can help identify issues like caking or moisture absorption, which may occur if packaging integrity is compromised. Ensure the supplier provides a bill of lading and packing list that match the contracted specifications to avoid discrepancies during customs clearance.
