Cherry gum

Description

A transparent, water soluble mucilage obtained as exudations from all species of cherry trees as well as other Prunus species trees (pear, peach, plum, apricot, almond). Cherry gum contains Arabinose, Galactose, Mannose, Xylose, and glucuronic acid. Fruit gums were used occasionally as binders for watercolor paints for at least a thousand years (Mayer 1969). It has also been added to egg or casein emulsions to increase glossiness (Doerner 1934).
