Food grade 99% Calcium phosphate monobasic CAS 10031-30-8

1. Product Overview

Calcium phosphate monobasic monohydrate (monocalcium phosphate monohydrate; MCP; Ca(H₂PO₄)₂·H₂O, CAS 10031-30-8) is the hydrated form of the most acidic calcium phosphate salt — a white crystalline powder and the standard commercial form of monocalcium phosphate used across food, agriculture and nutrition. In the bakery industry it is the classic fast-acting leavening acid (food additive E341(i)): combined with sodium or potassium bicarbonate it releases carbon dioxide, making cakes, pancakes, muffins and biscuits rise quickly and evenly. In agriculture it is the water-soluble phosphate core of superphosphate fertilizers (single and triple superphosphate), delivering plant-available phosphorus to crops. The same bioavailable calcium and phosphorus profile makes it a standard mineral supplement in animal feed. One product, three industries — food leavening, fertilizer and feed nutrition — all built on its acidity and water-soluble phosphorus.

Core value propositions:

● Fast-Acting Leavening Acid (Core Application): the standard monohydrate form (MCP-M) used in baking — reliable CO₂ release for consistent rise;

● Water-Soluble Phosphate for Fertilizers: plant-available phosphorus in single and triple superphosphate;

● Calcium + Phosphorus Nutrition: bioavailable mineral source for animal feed and food fortification;

● Food-Grade Purity: E341(i) compliant grades for baking and food processing.

2. Product Information (Quick Facts)

3. Chemistry & Structure

Calcium phosphate monobasic monohydrate, Ca(H₂PO₄)₂·H₂O (MW 252.07), is the monohydrate of the most acidic calcium phosphate salt: each formula unit carries two dihydrogen phosphate (H₂PO₄⁻) groups and one molecule of water of crystallization. It forms white/colorless crystalline solids with a triclinic structure. Food-grade material is produced by reacting calcium hydroxide with phosphoric acid (Ca(OH)₂ + 2 H₃PO₄ → Ca(H₂PO₄)₂ + 2 H₂O) and crystallizing as the monohydrate; fertilizer-grade material is made by acidulating phosphate rock — with phosphoric acid it forms triple superphosphate, and with sulfuric acid it forms single superphosphate together with gypsum. The two dihydrogen phosphate groups make the compound strongly acidic in water, which is the basis of its leavening action: with bicarbonate it releases carbon dioxide, and in soil it dissolves to give plant-available phosphate. On heating to ≈ 109 °C the water of crystallization is driven off with decomposition, and under improper storage it slowly converts to dicalcium phosphate, losing acidity. It is a white powder with a density of ≈ 2.22 g/cm³, is slightly soluble in water (≈ 2 g/100 mL), soluble in dilute acids, and is non-flammable.

4. Key Features & Benefits

● Standard baking form: the monohydrate (MCP-M) is the form most commonly supplied for leavening applications.

● Fast-acting leavening acid: quick, controlled CO₂ release in baked goods.

● Water-soluble phosphorus: readily plant-available phosphate for fertilizer value.

● Dual mineral nutrition: supplies both calcium and phosphorus.

● Multi-grade versatility: food (E341(i)), feed and fertilizer grades from one product line.

● Stable, non-flammable solid: safe storage and transport.

● Consistent quality: controlled assay (Ca and P₂O₅ content), pH and particle size with COA.

5. Main Applications

5.1 Food & Bakery — Leavening Acid (Core Application)

MCP monohydrate is the classic fast-acting leavening acid of the baking industry:

● Baking powders and self-rising flour: reacts with sodium/potassium bicarbonate to release CO₂ and leaven dough.

● Pancake, cake, muffin and biscuit mixes: fast-acting, consistent rise — releases most CO₂ within minutes of mixing.

● Double-acting baking powder: combined with slow-acting sodium acid pyrophosphate (SAPP).

● Food additive E341(i): acidity regulator and calcium source in processed foods.

5.2 Fertilizers & Agriculture

● Triple superphosphate (TSP): Ca(H₂PO₄)₂ produced from phosphate rock and phosphoric acid.

● Single superphosphate (SSP): produced with sulfuric acid, alongside gypsum.

● Plant nutrition: water-soluble phosphate for direct crop root uptake.

5.3 Animal Feed & Nutrition

● Feed-grade monocalcium phosphate: calcium and phosphorus mineral supplement for poultry, swine and cattle.

● Bioavailable phosphorus source in compound and mineral feeds.

5.4 Food Processing & Fortification

● Acidity regulator in processed foods and beverages.

● Calcium fortification in nutrition products.

8. FAQ

Q1: What is calcium phosphate monobasic monohydrate used for?

Calcium phosphate monobasic monohydrate (monocalcium phosphate, MCP) is a multi-industry phosphate. In food it is the classic fast-acting leavening acid (E341(i)) used in baking powders, pancake mixes and processed foods; in agriculture it is the water-soluble phosphate component of single and triple superphosphate fertilizers; and in animal nutrition it is a feed-grade source of calcium and phosphorus.

Q2: Why is it a good leavening agent?

Because it is acidic, it reacts quickly with sodium or potassium bicarbonate to release carbon dioxide, which expands the batter or dough and makes baked goods rise. The monohydrate form (MCP-M) is fast acting — it releases most of its CO₂ within minutes of mixing — which makes it the standard leavening acid for pancake, cake and muffin mixes, and for double-acting baking powders when combined with a slow-acting acid such as sodium acid pyrophosphate (SAPP).

Q3: Is calcium phosphate monobasic monohydrate safe to handle?

Yes, in normal industrial use. It is a food additive (E341(i)) approved for food use, non-flammable and chemically stable (NFPA health 1). The fine powder can irritate the eyes and respiratory tract, so use dust control, eye protection and gloves when handling. Avoid contact with alkaline materials, and store in a dry, sealed container — moisture and improper storage can gradually convert it to dicalcium phosphate and reduce its leavening performance. Follow the SDS for full handling guidance.
