E 440(Ii) Amidated Pectin – Eu Specification

COMMISSION REGULATION (EU) No 231/2012 of 9 March 2012



Amidated pectin consists mainly of the partial methyl esters and amides of polygalacturonic acid and their ammonium, sodium,

potassium and calcium salts. It is obtained by extraction in an aqueous medium of appropriate strains of edible plant material,

usually citrus fruits or apples and treatment with ammonia under alkaline conditions. No organic precipitant shall be used other than

methanol, ethanol and propan-2-ol
