In another embodiment a combination of physiological cooling agents is made in a modified release structure. The modified release/cooling agents combination is preferably obtained by physically modifying the properties of the combination of cooling agents by coating and drying. When incorporated into gum and confections, these particles are adapted to enhance the shelf stability of the flavor and/or produce a modified release. In another embodiment, coated chewing gum has a coating that comprises combinations of physiological cooling agents. The preferred inventive chewing gum provides a high flavor impact in which the harsh notes normally associated with such a high flavor impact have been reduced or eliminated. ## Claims ### Claim 1 A method of producing chewing gum with combinations of physiological cooling agents comprising the steps of: a) mixing at least two physiological cooling agents together with a release modification material; b) treating the cooling agents to provide a modified release; and c) adding a quantity of the modified release cooling agents to a chewing gum composition to provide a cooling agent level in the gum of from about 0.001% to about 2%. ### Claim 2 (depends on 1) The method of claim 1 wherein the physiological cooling agents are selected from the group consisting of N-substituted p-menthane carboxamides, p-menthane carboxylic acids, and other p-menthane carboxamides, acyclic carboxamides, menthol esters, acids, and menthol salts, menthol derivatives, other physiological cooling agents and combinations thereof. ### Claim 3 (depends on 1) The method of claim 1 wherein the cooling agents are treated by an encapsulation process. ### Claim 4 (depends on 3) The method of claim 3 wherein the cooling agents are encapsulated by a spray drying process. ### Claim 5 (depends on 3) The method of claim 3 wherein the cooling agents are encapsulated by a fluid bed coating process. ### Claim 6 (depends on 1) The method of claim 1 wherein the cooling agents are treated by being entrapped in an extrusion process. ### Claim 7 (depends on 1) A chewing gum made according to the method of claim 1. ### Claim 8 A chewing gum comprising a gum base, a sweet bulking agent, a flavor and from about 0.001% to about 2% of a modified release physiological cooling composition, said modified release physiological cooling composition comprising a mixture of at least two physiological cooling agents a release modification material, wherein said mixture has been treated to provide a modified release profile of the physiological cooling agents. ### Claim 9 (depends on 8) The chewing gum of claim 8 wherein the physiological cooling agents are selected from the group consisting of N-substituted p-menthane carboxamides, p-menthane carboxylic acids, and other p-menthane carboxamides, acyclic carboxamides, menthol esters, acids, and menthol salts, menthol derivatives, other physiological cooling agents and combinations thereof. ### Claim 10 (depends on 9) The chewing gum of claim 9, wherein one of the physiological cooling agents is N-[[5-methyl-2-(1-methylethyl)-cyclohexyl]carbonyl]glycine. ### Claim 11 (depends on 9) The chewing gum of claim 9, wherein one of the physiological cooling agents is N-(4-methoxyphenyl)-p-menthane-3-carboxamide. ### Claim 12 (depends on 9) The chewing gum of claim 9, wherein one of the physiological cooling agents is N-(t-butyl)-p-menthane-3-carboxamide. ### Claim 13 (depends on 9) The chewing gum of claim 9, wherein one of the physiological cooling agents is ethylene glycol ester of p-menthane-3-carboxylic acid. ### Claim 14 (depends on 9) The chewing gum of claim 9, wherein one of the physiological cooling agents is N-(p-benzene acetonitrile)-p-menthane-carboxamide. ### Claim 15 (depends on 9) The chewing gum of claim 9, wherein one of the physiological cooling agents is N-(2-(Pyridin-2-yl)ethyl)-3-p-menthane-carboxamide. ### Claim 16 (depends on 9) The chewing gum of claim 9 wherein the cooling agents are treated by an encapsulation process. ### Claim 17 (depends on 16) The chewing gum of claim 16 wherein the encapsulation process is a fluid bed coating process. ### Claim 18 (depends on 9) The chewing gum of claim 9, wherein the cooling agents are treated by a spray drying process. ### Claim 19 (depends on 9) The chewing gum of claim 9, wherein the cooling agents are treated by a spray chilling process. ### Claim 20 (depends on 9) The chewing gum of claim 9, wherein the cooling agents are treated by being entrapped in an extrusion process.
