Dicalcium phosphate (DCP) is a calcium and phosphorus source used extensively in dietary supplements, baked goods, and pharmaceutical tablets. Available in both anhydrous and dihydrate forms, it functions as a dough conditioner, leavening agent, mineral source, and yeast nutrient. Manufacturers producing kosher-certified products need verified documentation that their DCP supply meets rabbinical standards.
Leading producers like Innophos hold active kosher certifications from the Orthodox Union, with their dicalcium phosphate anhydrous and dihydrate grades both certified as pareve. These certifications are valid for Passover and year-round use, covering the broadest range of kosher food applications.
Kosher Certification Details for DCP
The Orthodox Union has certified multiple grades of dicalcium phosphate from Innophos, Inc., based in Cranbury, New Jersey. According to their certification letter, Dicalcium Phosphate Anhydrous carries the OU symbol and is classified as pareve, meaning it contains no meat or dairy components. The certification requires the OU symbol to appear on qualifying product and is approved for Passover use.
Dicalcium phosphate dihydrate FCC from Innophos holds the same kosher status. The Kashruth Division certification (reference 11690-02) covers this grade through December 31, 2026. Manufacturers should verify the expiration date on each lot’s kosher certificate to maintain compliance.
Food and Supplement Applications
In dietary supplements, dicalcium phosphate serves as both a calcium source and a tablet excipient. It provides the structural integrity needed for direct compression tableting while delivering bioavailable calcium and phosphorus. Many multivitamin and mineral supplement formulations rely on DCP as a primary ingredient.
In baking, DCP functions as a leavening agent and dough conditioner. It reacts with baking soda to produce carbon dioxide, creating proper rise in biscuits, pancakes, and self-rising flour blends. As a yeast nutrient, it supports fermentation in bread doughs and other yeast-leavened products.
Quality Standards and Compliance
Food-grade dicalcium phosphate must meet FCC specifications for purity, heavy metals, and arsenic content. Innophos products carry BRCGS certification alongside their kosher status, confirming adherence to global food safety standards. Additional compliance documentation available from distributors includes GMP statements, FSMA compliance letters, and PFAS statements.
The USP/FCC grade designation is important for pharmaceutical and supplement applications where stricter purity requirements apply.
Selecting the Right DCP Grade
Dicalcium phosphate anhydrous and dihydrate have different moisture contents and functional properties. The anhydrous form contains no water of crystallization and offers higher calcium concentration per gram. The dihydrate form (CaHPO4 2H2O) is more commonly used in food applications due to its consistent particle size and flow characteristics.
For kosher applications, both forms carry identical pareve certification. The choice between them depends on your formulation requirements, including desired calcium delivery, compression properties, and moisture sensitivity of the finished product.
