What is the Calcium hydrogenphosphate dihydrate?

Calcium hydrogenphosphate dihydrate is white crystalline solid, while it's Molecular Formula is CaHPO4 . 2(H2O). white crystalline solid Dicalcium phosphate dihydrate is only slightly soluble at ordinary temperatures of mixing and holding doughs and batters. As a result, it does not release acidity for reaction with soda until late in the baking stage, when the temperature reaches 135 to 140°F. Since DCP·2H20 does not begin to react below 135°F, and the interior structure of a baked product begins to firm at about 160°F, a product that bakes rapidly may not provide sufficient time for complete release of all the C02. DCP·2H2 0, therefore, cannot be used in biscuits, pancakes or any baked product that is completely baked in less than 20 min.Dicalcium phosphate dihydrate is seldom used by itself in leavening systems but is usually combined with fasterreacting acidic phosphates. Its major applications are in cake mixes, frozen bread doughs, and other products requiring a half hour or more to complete baking. It has a low neutralizing value, and therefore more DCP·2H20 is required to neutralize a given amount of soda than for other phosphate-leavening acids.

What is the CAS number for Calcium hydrogenphosphate dihydrate?

The CAS number of Calcium hydrogenphosphate dihydrate is 7789-77-7.

Calcium hydrogenphosphate dihydrate(Cas 7789-77-7) Usage

Description

Dicalcium phosphate dihydrate (DCPD) is a versatile compound with diverse applications across medical, nutritional, dental, food, industrial, and agricultural sectors. Its role as a source of calcium and phosphorus, leavening agent in baking, and additive in dental products underscores its significance in various industries. The utilization of DCPD contributes to the enhancement of product quality, nutritional fortification, and agricultural productivity.

Uses

Calcium Supplement: Dicalcium phosphate dihydrate is utilized in medical settings to address conditions associated with low calcium levels, such as osteoporosis, osteomalacia, hypoparathyroidism, and latent tetany. It serves as a source of supplemental calcium to support bone health and muscle function.

Leavening Agent: Dicalcium phosphate dihydrate serves as a leavening salt in baking applications. When exposed to water and heat, it decomposes into an acid, contributing to the rising of baked goods such as bread, cakes, and pastries.
