Abstract: A composition of matter and method for administering a bioactive substance to the post-rumen portion of the digestive system of a ruminant substantially without introducing the substance to the rumen portion of the digestive system is provided. The composition of matter comprises particles which have a specific gravity between about 0.3 and 2.0, preferably between about 1.0 and 2.0. The particles comprises a core comprising bioactive substance; a hydrophobic coating essentially completely encapsulating said core in a quantity sufficient to essentially preclude introduction of bioactive substance into the rumen; and a surfactant applied to the surface of the hydraphobic coating in a quantity sufficient to ensure that said particles do not float on the rumen. The method comprises orally administering this composition of matter to a ruminant.

Abstract: A sugar-free, low-calorie chewing gum utilizing polydextrose as the sole soluble bulking agent. A non-sweet chewing gum with a snack-type flavor or a low-calorie sweetened gum with aspartame or saccharin.

Abstract: This invention relates to a sweetened chewing gum composition which contains L-aspartyl-L-phenylalanine ethyl ester (APM) in amounts up to 1.5% by weight of the total product. The improvement comprises a gum which has a pH of between 5.0 and 7.0 so that the degradation of APM to diketopiperazine is minimized and the storage stability of the gum is greatly increased.

Abstract: This invention relates to a product and process in which L-aspartyl-L-phenylalanine methyl ester is fixed in gum Arabic and/or the reaction product of a compound containing a polyvalent metallic ion, with an ungelatinized starch acid-ester of a substituted dicarboxylic acid whereby the decomposition rate of the L-aspartyl-L-phenylalanine methyl ester when employed in a chewing gum system is greatly reduced.

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.

Abstract: This invention relates to a chewing gum composition which comprises gum base, sweetener, flavor and xylitol. The xylitol is contained in the gum in amounts less than 50% by weight of the total gum composition, the xylitol being effective to extend the storage stability of the gum.
