Chemical Construction

Calcium sulfate is a food additive used as an anticaking agent, dough conditioner and strengthener, flour treatment agent, pH regulator, thickenner and yeast food.


Calcium sulfate could be discovered naturally in limestones. Commercially accessible calcium sulfate is obtained from gypsum.1,2

Calcium sulfate serves a number of capabilities in baked items:1,2

  • Anticaking agent: prevents powder caking, lumping or agglomeration.
  • Coloring adjunct: aids within the preservation of shade in coatings.
  • Dough strengthener: modifies starch and gluten to offer a extra secure dough.
  • Firming agent: prevents the collapse throughout processing.
  • Flour bleaching remedy
  • Leavening assist: supplies meals for yeast enhancing leavening.
  • Nutrient complement: supplies calcium for dietary worth.
  • Stabilizer and thickener: supplies physique and improved consistency.
  • Texturizer: improves baked good texture.
  • pH regulator: works as a pH buffer and processing assist

Calcium sulfate can be utilized as a calcium complement within the fortification of bread and flours. It’s thought-about protected for day by day consumption as much as 8.5 g of anhydrous calcium sulfate per day, this worth corresponds to 2500 mg of calcium per day.3

Industrial manufacturing

Calcium sulfate is commercially produced by two course of, relying on the kind:2

USG Terra Alba

  • Grinding: excessive purity gypsum (with 20% water of crystallization) is floor to desired particle dimension.
  • Air separation: gypsum is heated, at temperatures above 50oC (122oF,) a part of the crystallization water is launched. At 180 oC (356oF) over 75% of the water is launched and full evaporation is achieved when temperature exceeds 400 oC (752 oF).

Snow White Filler

  • Calcing: gypsum is heated to temperatures from 300 – 450 oC (572 – 842 oF) within the presence of steam in a calcinating reactor.
  • Grinding: anhydrous calcium sulphate is floor to desired particle dimension.

Calcium sulfate is used primarily within the manufacturing of bread, and within the fortification of bread flour, cookies, brownies and breads. When utilizing calcium sulfate some consideration should be taken into consideration:2,4

  • As a flour bleaching agent: it’s combined with benzoyl peroxide at a ratio of not more than 6:1 by weight.
  • As a dietary complement: for calcium enrichment 0.64% of calcium sulfate and 0.6% of an emulsifier by flour weight could be added for optimum enrichment.
  • As a sodium sulfate substitute: it may exchange as much as 32% of sodium within the producer of brown bread with out affecting palatability and total product high quality.
  • As a pH regulator: it may be used at a utilization degree of 0.1 – 0.6%.

Typical calcium sulfate utilization ranges in widespread meals merchandise:2


Calcium sulfate is taken into account GRAS by the FDA for its direct addition to meals merchandise, in ranges that don’t exceed good manufacturing practices.2

Within the EU, calcium sulfate ( E 516) is taken into account protected and it’s regulated by the EU Fee No 231/2012.5
