DESCRIPTION
Calcium Alginate occurs as a white to yellow, fibrous or granular powder. It is the calcium salt of alginic acid. It is insoluble in water, but it is soluble in alkaline solutions or in solutions of substances that combine with the calcium. It is insoluble in organic solvents.
Function: Stabilizer; thickener; emulsifier.
REQUIREMENTS
Identification: Place about 5 mg of sample into a test tube, add 5 mL of water, 1 mL of a freshly prepared 1:100 solution of naphtholresorcinol:ethanol, and 5 mL of hydrochloric acid. Heat the mixture to boiling, boil gently for about 3 min, and then cool to about 15C. Transfer the contents of the test tube into a 30-mL separator with the aid of 5 mL of water, and extract with 15 mL of isopropyl ether. Perform a blank determination and make any necessary correction. The isopropyl ether extract from the sample exhibits a deeper purple hue than that from the blank.
Assay: A sample yields not less than 18% and not more than 21% of carbon dioxide (CO2), corresponding to between 89.6% and 104.5% of Calcium Alginate (equiv wt 219.00), calculated on the dried basis.
Arsenic: Not more than 3 mg/kg.
Lead: Not more than 5 mg/kg.
Loss on Drying: Not more than 15.0%.
