Polysaccharide gums processed foods

Antibodies that are specific for polysaccharide gums are used for detection and identification of gum additives in processed foods, beverages and confectionaries, Fig. (47). The tests are performed with a control of gum and its complementary antibody with food products and the antibody. The products tested were ice cream, soup, candy and salad dressing. All but the last yielded positive tests with the specific antibodies that were used.

Products of commercial importance extend well beyond enzymes and include the production of large molecules, such as polysaccharides. Xanlhan is an example. This is a gum widely used in food processing. See also Xanthan Gum.
