Tricalcium Phosphate FAQ

1: What is Tricalcium Phosphate (TCP)?

Tricalcium Phosphate, short for TCP, chemical formula Ca₃(PO₄)₂, CAS 7758-87-4, also named Tribasic Calcium Phosphate. It is white odorless fine powder with stable chemical property, widely divided into food grade, feed grade, pharma & cosmetic grade as multi-functional phosphate raw material.

2: What is E number of food grade TCP?

Food grade Tricalcium Phosphate is E341(iii), fully compliant with FCC, EU food additive standards, can be legally used as food fortifier and anti-caking agent globally.

3: What’s the difference between food grade, feed grade and pharma grade TCP?

Food Grade: Strict control of heavy metal, arsenic, fluoride; used for milk powder, seasoning, bakery powder as calcium supplement & anti-caking agent.

Feed Grade: Balanced calcium phosphorus ratio, lower purification standard than food grade, for livestock, poultry and aquaculture feed mineral additive.

Pharma & Cosmetic Grade: Ultra-low impurity, super fine particle size, applied as tablet diluent, toothpaste mild abrasive.

4: What are the main functions of food grade TCP?

Calcium & phosphorus nutrition fortifier

Anti-caking agent to prevent powder agglomeration

pH buffer and texture stabilizer

Improves powder flowability for long-term storage

5: Can TCP be mixed with other food additives?

Yes. TCP has mild neutral property, compatible with most common food raw materials such as whey powder, maltodextrin, salt, baking agents without chemical reaction.

6: What package sizes do you supply for export?

Standard export package: 25kg kraft paper bag with plastic inner liner;

Bulk shipment: 1000kg ton jumbo bag;
