Calcium sorbate in food

Melting range of sorbic acid derived from the sample
(Vol. 4) 132 - 135o
Acidify a solution of the sample with dilute hydrochloric acid TS. Collect the precipitated sorbic acid on a filter paper, wash free of chloride with water and dry under vacuum over sulfuric acid.
Test for unsaturation: to 2 ml of a 1 in 10 solution of the sample, add a few drops of bromine TS. The colour of the bromine disappears.
Calcium sorbate can be found in candied peel, cheese, cider, concentrated fruit juice, dessert sauces, dried apricots, fillings and toppings, fermented milks, frozen pizzas, fruit salads, gelatin capsules, margarine, processed cheese spreads and slices, soft drinks, soup concentrates, sweets and yoghurt.
