What is Calcium Sulphate?
Calcium Sulphate, commonly found in nature as gypsum, is a calcium salt valued in food applications for its firming, coagulating, and dough-conditioning properties. Food Grade Calcium Sulphate is a white, odourless crystalline powder typically supplied as the dihydrate, refined and processed to meet food safety standards distinct from industrial or construction-grade gypsum.
Polychem Industries supplies Food Grade Calcium Sulphate to tofu manufacturers, bakery ingredient companies, and brewing industry customers across India and internationally. Its role as a coagulating agent and dough conditioner, combined with its function as a calcium fortification ingredient, makes it a valuable functional additive across several food categories.
Available Grades
| Grade | Form | Purity | Standard | Applications |
|---|---|---|---|---|
| Food Grade | White crystalline powder | 98%+ (Food Grade) | FSSAI / FCC / E516 | Tofu coagulant, baking, brewing, dough conditioning |
Applications & Uses
Tofu Coagulant
One of the most significant food applications. Calcium Sulphate is used as a coagulant in tofu production, causing soy milk proteins to curdle and form the characteristic tofu structure, while also fortifying the final product with calcium.
Baking & Dough Conditioning
Used as a dough conditioner and yeast nutrient in bread and bakery production, providing calcium that supports yeast fermentation activity and contributes to improved dough strength and texture.
Brewing Industry
Used in beer brewing as a water treatment additive (commonly referred to as "brewer's gypsum") to adjust water mineral content, particularly calcium and sulphate levels, which influences mash pH, yeast performance, and final beer flavour profile.
Food Firming Agent
Used as a firming agent in canned and processed fruits and vegetables, helping maintain texture and prevent excessive softening during processing and storage.
Calcium Fortification
Used as a calcium source in certain fortified food products, contributing to the nutritional calcium content of foods such as tofu, certain baked goods, and fortified beverages.
Food Processing Aid
Used as a processing aid in various food manufacturing operations requiring its specific firming, coagulating, or mineral-supplementing functionality.
