Particles of N-[N-(3,3-dimethylbutyl)-L- -aspartyl]-L-phenylalanine 1-methyl ester

1. Field of the Invention N-[N-(3,3-dimethylbutyl)-L- -aspartyl]-L-phenylalanine 1-methyl ester is converted from a light powder to relatively dustless, free-flowing particles with and without the use of binders using extrusion and spheronization processes. These particles are suitable for use in a variety of applications. Food products sweetened with extruded or spheronized N-[N-(3,3-dimethylbutyl)-L- -aspartyl]-L-phenylalanine 1-methyl ester and methods of sweetening food products with such N-[N-(3,3-dimethylbutyl)-L- -aspartyl]-L-phenylalanine 1-methyl ester are also disclosed.
