Polysaccharides 676<br />

NAME: Kappa-carrageenan<br />

CATEGORY: Polysaccharides<br />

FOOD USE: All food products/ Edible films and coatings<br />

SYNONYMS: CAS 9004-07-1/ EINECS 232-524-2/ E407/ E407a/ Carrageenin/ Carrageen/ Carragheenan/ Chondrus/<br />

Irish Moss/ Processed Euchema Carrageenan (PES)/ Philippine Natural Carrageenan (PNG)/<br />

Alternatively Refined Carrageenan (ARC)<br />

FORMULA: (C6 H8 S0.5 O6)n. A polymer formed from a disaccharide repeating unit composed of a 4-O-sulfatobeta-D-galactopyranosyl<br />

unit and a 3,6 anhydro-alpha-D-galactopyranosyl unit<br />

MOLECULAR MASS: Variable, but typically 700,000 to 5 million<br />

ALTERNATIVE FORMS: Blends including kappa-carrageenans; polymers in which most but not all the units are of the kappacarrageenan<br />

type; sodium salts; potassium salts; calcium salts; ammonium salts, etc.<br />

PROPERTIES AND APPEARANCE: White to yellow powders or flakes<br />

WATER CONTENT MAXIMUM IN %: 0–22<br />

ASH MAXIMUM IN %: 19–42<br />

SOLUBILITY % AT VARIOUS The sodium salt of kappa-carrageenans is soluble in cold water, but potassium and calcium salts must<br />

TEMPERATURE/pH COMBINATIONS: be heated to >60°C. Kappa-carrageenan will dissolve in hot concentrated sugar solutions but is<br />

insoluble in concentrated salt solutions and 35% ethanol. It is insoluble in vegetable oils and propylene<br />

glycol.<br />

Optimum solubility occurs at pH 9 and declines as the pH is reduced (
