Patent ID: 7767243

Claim:
A method of preparing a liquid flavoring composition comprising: a) combining menthol and at least one physiological cooling agent selected from the group consisting of N-substituted p-menthane carboxamides, acyclic carboxamides, menthyl succinate and combinations thereof; b) heating at least one of the menthol and the at least one physiological cooling agent and forming a liquid composition of the menthol and the at least one physiological cooling agent, wherein the combining and heating steps are performed in any order; and c) cooling the composition of the menthol and the at least one physiological cooling agent to less than about 30° C. while maintaining the composition in a liquid state to create the liquid flavoring composition, d) wherein the liquid flavoring composition comprises about 25% to about 75% by weight menthol and about 25% to about 75% by weight of the at least one physiological cooling agent; and said liquid flavoring composition is stable at a temperature lower than the individual melting temperatures of said menthol and cooling agent.
