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. Evaluate this grade in the intended flour system and process; this listing does not establish a specific dough-strengthening effect.
JECFA also lists yeast food. Confirm the complete nutrient system and permitted application rather than assuming a universal effect.
For calcium and phosphorus applications, request measured nutrient content and its reporting basis. Check dispersion, sedimentation and sensory behavior in the food system; composition alone does not establish a finished-food nutrition claim.
For dry blends, specify the physical form and particle-size distribution needed for your equipment. Confirm bulk density, flow and blend uniformity by grade-specific data and trials rather than assuming every DCP powder behaves alike.
Technical information
The values below are commercial purchasing references, not a batch COA or a universal regulatory standard. Confirm the hydration form, reporting basis, 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 |
Reporting basis and methods: Assay is stated on an anhydrous basis. Specify the P₂O₅ sample basis and analytical method. The ignition reference value is 8.5%, with an acceptance comparator that requires agreement; the table presents ≤8.5% as a purchasing reference. Establish the signed limit, ignition temperature and duration before acceptance. Loss on ignition is distinct from loss on drying, and P₂O₅ content is not an elemental phosphorus result.
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.
Lead requires a tighter limit for JECFA qualification: the commercial lead value of 0.0005% equals 5 mg/kg, whereas the linked JECFA monograph specifies no more than 4 mg/kg. The listed arsenic and fluoride values convert to 3 mg/kg and 50 mg/kg respectively, matching those numerical JECFA limits. This does not establish full compliance: obtain a specification meeting every applicable requirement and batch evidence using the required methods.
JECFA specifies anhydrous loss on drying of no more than 2% at 200°C for 3 hours; the commercial ignition result does not demonstrate that requirement. “Heavy metals (as Pb)” is a separate aggregate parameter, not the individual lead test or proof that all metal limits are met.
For U.S. food-use context, see 21 CFR 182.1217 and the nutrient-supplement provisions in 21 CFR 182.8217. These provisions concern use under good manufacturing practice; assess your food category, formulation and labeling separately.
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 sample preparation and whether assay, P2O5, calcium and phosphorus results are reported as-is, after drying or on an anhydrous basis. Request actual calcium/phosphorus results when needed; do not substitute theoretical conversions for testing.
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.
Packaging and logistics references
Commercial references are 25 kg bags, a 500 kg minimum order and 22 metric tons per 20-foot container. Confirm current availability, bag construction, palletizing and destination payload restrictions in the quotation. These photographs are logistics references, not evidence of current inventory. Request the source-specific shelf life and storage specification; no shelf-life guarantee is stated here.
Storage & handling
Calcium phosphate decision path
Use related pages to keep product identity separate from formulation and mineral-selection questions. Anhydrous DCP is not presented here as a direct substitute for MCP, SAPP, SALP or dihydrate DCP in a leavening system; select a suitable acid grade and validate the complete recipe and process.
Buyer questions
JECFA identifies calcium hydrogen phosphate as a dough conditioner and yeast food. Anhydrous DCP may also be evaluated as a calcium/phosphorus ingredient where permitted. Suitability depends on the selected grade, food system, processing and market requirements; this page does not guarantee a leavening effect.
Anhydrous DCP is CaHPO₄, CAS 7757-93-9, with a molar mass of 136.06 g/mol. DCP dihydrate is CaHPO₄·2H₂O, CAS 7789-77-7, with a molar mass of 172.09 g/mol. Quote the forms separately and compare their analytical bases and application data before selecting a grade.
No. The commercial lead limit is 5 mg/kg, while the cited JECFA limit is 4 mg/kg. The listed loss on ignition also does not demonstrate JECFA loss on drying. Request a signed specification addressing all applicable requirements and a batch COA with defined test methods.
No equal-weight substitution is proposed. MCP, DCP and TCP have different identities; hydration form and grade also matter. For a baking system, qualify the leavening acid, neutralization balance and reaction behavior under your mixing, holding and heating conditions.
JECFA describes calcium hydrogen phosphate as sparingly soluble in water. For a food formulation, evaluate dispersion, particle size and sedimentation under the actual pH, mixing and processing conditions rather than treating it as a readily soluble calcium ingredient.
No. This page is for food grade anhydrous DCP. Feed grade qualification uses its own nutrient guarantees, impurity limits, species requirements and documentation; a feed COA is not evidence of food-grade suitability.
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 current order terms, palletizing and destination-specific loading before ordering.
Request the current signed specification, SDS and representative COA, followed by the shipment batch COA. Ask for the required food-safety, origin, allergen or religious-certification documents and confirm their availability and exact product, site and validity scope.
Provide anhydrous or dihydrate identity, food standard, assay basis, critical impurity limits, particle-size requirement, intended food application, quantity, packaging, destination country or port, delivery terms and timing.
