Abstract
Abstract Certain substituted succinic acid compounds, particularly carboxymethyloxysuccinic acid and lactoxysuccinic acid and salts thereof are incorporated as an additive in edible materials, particularly food products. The compounds act as acidulating agents and buffering agents in food products; and the acid forms also impart a pleasant tart taste thereto. In addition, these acids and salts are essentially non-nutritive and non-caloric.
