E440 - Pectin

Food additives

Pectin is a natural acid polysaccharide present in nearly all fruits, especially apples, quinces and oranges.
It is commercially produced from apple pulp and orange peels.
Sodium, potassium, and ammonium pectates are the respective salts of pectin.
Amidated pectin is prepared by treating pectin with ammonia, after which amides are formed at the acid side chains.
