DESCRIPTION
Calcium Sulfate occurs as a
fine, white to slightly yellow-white powder. It is anhydrous or contains two
molecules of water of hydration.
Function Nutrient; yeast food; dough conditioner; firming
agent; sequestrant.
REQUIREMENTS
Identification: Dissolve about 200 mg of sample by warming it with a mixture of 4
mL of 2.7 N hydrochloric acid and 16
mL of water. A white precipitate forms when 5
mL of ammonium oxalate TS is added to 10
mL of the solution. Upon the addition of barium
chloride TS to the remaining 10 mL, a white
precipitate forms that is insoluble in hydrochloric and nitric acids.
Assay: Not less than
98.0% of CaSO4 i.e. Calcium Sulphate, calculated on the dried basis.
Fluoride: Not more
than 0.003%.
Lead: Not more than 2
mg/kg.
Loss on Drying Anhydrous: Not more than 1.5%; Dihydrate:
Between
19.0% and 23.0%.
Selenium: Not more
than 0.003%.
TESTS
Assay Dissolve 250 mg
of sample, accurately weighed, in 100 mL of
water and 4 mL of 2.7 N hydrochloric
acid, boil to effect solution, and cool. While stirring, preferably with a
magnetic stirrer, add about 30 mL of 0.05 M
disodium EDTA from a 50-mL burette, then add 25 mL
of 1 N sodium hydroxide and 300 mg of hydroxy naphthol blue indicator, and continue the
titration to a blue endpoint. Each milliliter of 0.05 M disodium EDTA is equivalent to 6.807 mg of
CaSO4.
