Locust bean gum is a polysacharide (a long chain made of sugars) made of
the sugars galactose and mannose.
Some other familiar polysacharides are starch and cellulose, which
are made of long chains of the sugar glucose.
In locust bean gum, the ratio
of mannose to galactose is higher than in
guar gum, giving it slightly different
properties, and allowing the two gums to interact synergistically
so that together they make a thicker gel than either one alone.
Locust bean gum is extracted from the endosperm of the seeds of
the carob tree Ceretonia siliqua, which grows in Mediterranean
