Abstract
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.
