Abstract
Abstract Chewing gums having longer lasting sweetness and flavor are prepared from compositions comprising a chewable gum base, flavor, sweetener in an amount sufficient to impart normally accepted sweetness to the gum, and L-aspartyl-L-phenylalanine methyl ester in an amount effective to produce longer lasting sweetness and flavor. The chewing gums may be either sugar-containing or sugarless.
