This invention provides a process for preparing an agglomerate of N-[N-(3,3-dimethylbutyl)-L-&agr;-aspartyl]-L-phenylalanine 1-methyl ester and a carrier comprising the steps of: (a) providing a premix solution comprising N-[N-(3,3-dimethylbutyl)-L-&agr;-aspartyl]-L-phenylalanine 1-methyl ester and a binding agent; (b) fluidizing a carrier; and (c) applying the premix solution of step (a) onto said fluidized carrier to form an agglomerate of said N-[N-(3,3-dimethylbutyl)-L-&agr;-aspartyl]-L-phenylalanine 1-methyl ester and said carrier. This invention is also directed to the novel agglomerates prepared by the process of this invention.
