Abstract
A process is disclosed wherein an ingredient is treated so that it will exhibit a controlled release when incorporated in chewing gum. According to the method, a quantity of a powdered ingredient 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 treated, e.g. by grinding and/or screening, to produce the desired particle size range in the agglomerated ingredient particles. These agglomerated particles comprise collections or clusters of ingredient particles which have been bound together by the agglomerating agent.
