Abstract: The invention relates to chewing gums containing dipeptide sweetener, both in a sugar-free and in a sugar-containing form, and other chewable products. Improved flavor, in terms of both quality and persistence, in particular in the case of products which also contain flavorings based on aldehydes, is achieved when the dipeptide sweetener is a sweetening salt of an aspartic-acid-derived dipeptide sweetener and a derivative of a sweetening acid. The particle size of the sweetening salt is preferably smaller than 200 &mgr;m, and the sweetening salt is preferably present in a quantity from 100 to 6000 ppm. The invention also relates to processes for production of such chewing gums.

Abstract: Aspartame powder for application in instant powder mixtures and instant desserts and consisting entirely or practically entirely of aspartame with a narrow particle size distribution with a d.sub.50 value in the range of from 40 to 80 .mu.m, with max. 10 wt %<20 .mu.m and max. 10 wt %>150 .mu.m; and process for the preparation, from dry or wet aspartame granules, of aspartame powder consisting entirely or practically entirely of aspartame, for application in instant powder mixtures and instant desserts, wherein granular aspartame having a moisture content of max. about 40 wt % is crushed, in dry or drying conditions at a temperature of 0-60.degree. C., or while supplying drying air having a temperature of 100-180.degree. C., in a first step in an impact mill while air is being supplied for discharging the crushed product from the mill, with drying if necessary to achieve a moisture content of less than 4 wt %, to a product in which at least 70 wt % of the particles is smaller than 150 .mu.
