Polysaccharides 700<br />

NAME: Gum ghatti<br />

CATEGORY: Polysaccharides<br />

FOOD USE: Confectionery/ Beverages/ Baked goods/ Emulsified foods<br />

SYNONYMS: Indian gum<br />

MOLECULAR MASS: Variable<br />

ALTERNATIVE FORMS: Gum ghatti is slightly acidic, so different salt forms are possible<br />

PROPERTIES AND APPEARANCE: White/off-white powder or amber to dark brown lumps<br />

SOLUBILITY % AT VARIOUS Gum ghatti is a complex mixture of which 10% are insoluble in water. The remainder are soluble in<br />

TEMPERATURE/pH COMBINATIONS: water, sucrose solutions, sodium chloride solution and ethanol solutions, but solubility in vegetable oils<br />

and propylene glycol is limited. Maximum viscosity is observed at pH 8<br />

FUNCTION IN FOODS: Emulsifier; flavouring agent; adjuvant; formulation aid; humectant; surface-finishing agent; stabiliser;<br />

thickener; firming agent; processing aid; texturiser; crystallisation inhibitor; for confections, flavour<br />

syrups, dietary fibre; foam stabiliser<br />

ALTERNATIVES: Gum arabic; karaya gum; gum tragacanth; maltodextrins; pyrodextrins; polydextroses; methyl<br />

celluloses; milk proteins (application-dependent)<br />

TECHNOLOGY OF USE IN FOODS: Solution of gum ghatti can be prepared by dispersing in aqueous solution at room temperature.<br />

Emulsions should be prepared with a high shear mixer.<br />

Gum ghatti is a complex branched arabinogalactan with a (1 Æ 6) beta-D-galactopyranosyl main<br />

chain with (1 Æ 4) beta-D-glucuronic acid, (1 Æ 2) mannose and some L-arabinose attached.<br />

In comparison with gum arabic it is more viscous, darker in colour and contains more insoluble<br />

material<br />
