Abstract: A process is disclosed for making a chewing gum with a fast release, stabilized chewing gum. According to the method, a quantity of aspartame (APM) is mixed with an agglomerating agent, such as a modified cellulose, and a limited quantity of a solvent for the agglomerating agent, such as water. The quantity of solvent is limited so as to produce a mixture which is only moist or damp. This damp mixture is characterized as being dust-free, non-flowing and crumbly. The damp mixture is then dried and the dried mixture is comminuted, e.g. by grinding, to produce particles of APM ingredient with essentially a maximum particle size of about 0.017 inches. These particles of APM ingredient are then added to a chewing gum formulation.
