Food ingredient · Acidic calcium phosphate · INS 341(i)
Monocalcium phosphate, also called calcium dihydrogen phosphate, is an acidic food-grade phosphate used in leavening systems, dough conditioning, mineral fortification and selected processed-food formulations.
Include the required form, standard, quantity, destination and food application for a relevant proposal.
Product overview
Food grade monocalcium phosphate (MCP) is an acidic calcium salt of phosphoric acid. Its standardized food-additive name is calcium dihydrogen phosphate, its Codex designation is INS 341(i), and it may be supplied as anhydrous Ca(H2PO4)2 or monohydrate Ca(H2PO4)2·H2O.
In bakery systems MCP reacts with alkaline leavening ingredients to release carbon dioxide. Its acid character and mineral content also make hydration form, particle profile, neutralizing behavior and destination-market compliance important purchasing variables.
Specify the hydration form
The forms differ in crystal-water content, formula weight and analytical behavior. State the required form on the purchase specification rather than ordering only by the abbreviation “MCP.”
Calcium dihydrogen phosphate without water of crystallization. Its formula is Ca(H2PO4)2 and the supplied CAS number is 7758-23-8.
Calcium dihydrogen phosphate containing one water of crystallization. Its formula is Ca(H2PO4)2·H2O and the JECFA identity reference lists CAS 10031-30-8.
Food processing functions
Actual use levels and permitted food categories depend on the formulation and destination market. Complete technical trials and regulatory review before commercial use.
An acidic component used with bicarbonates in baking powder, self-rising flour and suitable bakery formulations.
Used in qualifying flour and bakery systems as a dough conditioner and formulation aid.
Provides calcium and phosphorus in suitable fortified foods, premixes and nutrition formulations.
May serve as a mineral nutrient in selected yeast-based food processes and fermentation systems.
Used as a bulking, firming, curing or acidity-related ingredient where the formulation and local rules permit.
Suitable for selected dry mixes and compound ingredient systems after reaction-rate and compatibility testing.

Specification note: The source sheet appeared to contain OCR errors. “P₄O₆” was normalized to the conventional phosphate parameter P₂O₅, “sn.0003” was interpreted as ≤ 0.0003, and decimal commas were normalized. Confirm these interpretations against the signed specification before publication or contracting.

Storage & handling
Buyer questions
MCP is used in suitable food formulations as an acidic leavening ingredient, dough conditioner, calcium and phosphorus source, yeast nutrient, bulking agent and processing aid. Regulatory permission and dosage depend on the food category and destination market.
Anhydrous MCP is Ca(H2PO4)2. Monohydrate MCP is Ca(H2PO4)2·H2O and includes one water of crystallization. This changes formula weight, heating loss and handling behavior.
No. Monocalcium phosphate (MCP), dicalcium phosphate (DCP) and tricalcium phosphate (TCP) are different calcium phosphate salts. Their calcium-to-phosphorus ratios, acidity, solubility and food functions differ.
The reference packing is 25 kg per bag, with a stated minimum order quantity of 500 kg. Reference loading is 23 metric tons per 20-foot container. Confirm palletizing and destination-specific loading before ordering.
HACCP, Kosher, Halal and ISO are listed in the supplied product information. Ask the sales team for current documents and confirm that each certificate covers the exact product, manufacturing site and validity period required by your project.
Provide the hydration form, required specification or standard, particle-size or reaction-rate requirement, quantity, packaging, destination country or port, intended food application and delivery date.
