Food ingredient · Calcium phosphate · E341(ii)
Bespring supplies food grade anhydrous dicalcium phosphate (DCP), also called calcium hydrogen phosphate, for qualified dough-conditioning, yeast-food and mineral ingredient applications. This page covers the anhydrous source only; dihydrate DCP has a separate identity and product page.
Include the required form, standard, quantity, destination and food application for a relevant proposal.
Product overview
Food grade dicalcium phosphate anhydrous is calcium hydrogen phosphate, CaHPO4, CAS 7757-93-9 and INS/E341(ii). JECFA also uses the synonyms dibasic calcium phosphate and dicalcium phosphate.
It is sparingly soluble in water and contains no water of crystallization. Particle size, assay basis, loss on drying, impurity limits and destination-market requirements are therefore more useful purchasing variables than the abbreviation “DCP” by itself.
Specify the hydration form
This URL covers anhydrous CaHPO4. Dihydrate CaHPO4·2H2O has a different formula, formula weight, CAS reference and water-loss profile.
Calcium hydrogen phosphate without water of crystallization. Its formula is CaHPO4 and the commonly referenced CAS number is 7757-93-9.
Calcium hydrogen phosphate containing two waters of crystallization. Its formula is CaHPO4·2H2O and its CAS number is 7789-77-7.
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.
JECFA lists dough conditioner as a functional use. Validate flour system, particle size, processing sequence and legal use conditions.
JECFA also lists yeast food. Confirm the complete nutrient system and permitted application rather than assuming a universal effect.
Evaluate calcium and phosphorus contribution on the agreed analytical basis, then confirm finished-food claims and local authorization.
Assess particle-size distribution, bulk density, flow, segregation and compatibility in the complete powder blend.
Technical information
The values below reproduce the supplied purchasing specification in a consistent format. They are not a batch COA or a universal regulatory standard. Confirm the form, test methods and contractual limits before ordering.
| Test item | Unit | Reference specification |
|---|---|---|
| Calcium hydrogen phosphate (CaHPO4) content, anhydrous basis | % | 98.0–102.0 |
| P2O5 content | % | 50.0–52.5 |
| Arsenic (As) | % | ≤ 0.0003 |
| Fluoride (F) | % | ≤ 0.005 |
| Heavy metals (as Pb) | % | ≤ 0.0015 |
| Insoluble in hydrochloric acid | % | ≤ 0.05 |
| Loss on ignition | % | ≤ 8.5 (supplied anhydrous specification) |
| Lead (Pb) | % | ≤ 0.0005 |
| Cadmium (Cd) | % | ≤ 0.0001 |
| Mercury (Hg) | % | ≤ 0.0001 |
Specification note: The source sheet appeared to contain OCR errors; “P₄O₆” was normalized to the conventional DCP parameter P₂O₅. Loss on ignition in this commercial table is not interchangeable with JECFA loss on drying. Final acceptance must use the approved source specification, defined method and batch COA.
The FAO/WHO JECFA calcium hydrogen phosphate monograph identifies CAS 7757-93-9, INS 341(ii), CaHPO4, 98–102% assay after drying, sparing water solubility, and dough-conditioner/yeast-food functions. The U.S. FDA dibasic calcium phosphate record independently lists CAS 7757-93-9 and recognized technical effects. These references support identity context; they do not certify a Bespring batch or authorize every food application.
Anhydrous DCP qualification
Use the exact hydration form and analytical method as the comparison baseline.
Specify anhydrous CaHPO4, CAS 7757-93-9 and INS/E341(ii); do not accept an unqualified “DCP” description.
Confirm drying conditions and whether assay, P2O5, calcium and moisture-related values are reported as-is or after drying.
Match powder or granular form, particle-size distribution, bulk density and flow to feeding, blending and segregation risks.
Align fluoride, arsenic, lead, cadmium, mercury and other destination-specific limits with named test methods.
Verify the intended category, use level, technical function and labeling under manufacturing and destination-market rules.
Request the current signed specification, SDS, representative and batch COA, plus certificates valid for the exact source and period.
This page addresses food additive and food ingredient qualification. Animal-diet sourcing belongs on the feed grade DCP page; nutrient guarantees, contaminants, species rules and documents must be assessed separately.

Buyer questions
DCP is used in suitable food formulations as a leavening component, dough conditioner, buffer, calcium and phosphorus source, stabilizer and functional ingredient. Regulatory permission and dosage depend on the product and market.
No. This page covers food grade anhydrous CaHPO4, CAS 7757-93-9. Dihydrate CaHPO4·2H2O, CAS 7789-77-7, has a dedicated product page and should be quoted separately.
No. Dicalcium phosphate (DCP), monocalcium phosphate (MCP) 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 22 metric tons per 20-foot container. Confirm palletizing and destination-specific loading before ordering.
Request the current signed specification, SDS, representative and batch COA, plus applicable food-safety, quality, origin, allergen, Kosher, Halal or other certificates. Confirm that every document covers the exact product, manufacturing site and required period; availability is source-specific.
Provide the hydration form, required specification or standard, particle-size requirement, quantity, packaging, destination country or port, intended food application and delivery date.
