 686. Gum arabic (WHO Food Additives Series 26)
EXPLANATION Gum arabic, also known as gum acacia, is the dried gummy exudate from tropical and subtropical Acacia senegal trees.
Gum arabic consists of several high-molecular-weight polysaccharides and their salts, which on hydrolysis yield arabinose, galactose, rhamnose and glucoronic acid (Anderson et al., 1983).
An additive meeting this criterion must be used within the bounds of good manufacturing practice, i.e., it should be technologically efficacious and should be used at the lowest level necessary to achieve this effect, it should not conceal inferior food quality or adulteration, and it should not create a nutritional imbalance.
