CROSS REFERENCE TO RELATED APPLICATIONS [0001] The present application is a continuation of application Ser. No. 10/253,066, filed Sep. 23, 2002 (pending), which is a continuation of application Ser. No. 09/527,169, filed on Mar. 16, 2000, now U.S. Pat. No. 6,455,080, which is 1) a continuation of Application Serial No. PCT/US97/24166, filed Dec. 29, 1997, designating the United States, and 2) a continuation-in-part of application Serial No. PCT/US97/16731, filed Sep. 18, 1997, also designating the United States, all of which are hereby incorporated by reference. BACKGROUND OF THE INVENTION [0002] The present invention relates to chewing gum compositions and methods of producing chewing gum. More particularly, the invention relates to producing chewing gum containing a physiological cooling agent, specifically acyclic carboxamide. Preferably the physiological cooling agent has been treated to control its release and enhance shelf life stability. [0003] In recent years, efforts have been devoted to controlling release characteristics of various ingredients in chewing gum. Efforts have been directed at perfecting the use of high-intensity sweeteners within the chewing gum formulation, to thereby increase the shelf-life stability of the ingredients, i.e., the protection against degradation of the high-potency sweetener over time. [0004] Patent Cooperation Treaty Publication No. WO 89/03170 discloses a method of controlling the release of acesulfame K. In this process, the sweetener is encapsulated fully or partially to modify the release rate in chewing gum. [0005] Other patent publications disclose how a sweetener like aspartame can be physically modified to control its release rate in chewing gum. [0006] For example, U.S. Pat. No. 4,597,970 to Sharma et al. teaches a process for producing an agglomerated sweetener wherein the sweetener is dispersed in a hydrophobic matrix consisting essentially of lecithin, a glyceride and a fatty acid or wax having a melting point between 25 and 100.degree. C. The disclosed method uses a spray congealing step to form the sweetener-containing matrix into droplets, followed by a fluid-bed second coating on the agglomerated particles. [0007] U.S. Pat. Nos. 4,515,769 and 4,386,106, both to Merrit et al., teach a two step process for preparing a delayed release flavorant for chewing gum. In this process, the flavorant is prepared in an emulsion with a hydrophilic matrix. The emulsion is dried and ground and the particles are then coated with a water-impermeable substance. [0008] U.S. Pat. No. 4,230,687 to Sair et al. teaches a process for encasing an active ingredient to achieve gradual release of the ingredient in a product such as chewing gum. The described method involves adding the ingredient to an encapsulating material in the form of a viscous paste. High shear mixing is used to achieve a homogeneous dispersion of the ingredient within the matrix, which is subsequently dried and ground. [0009] U.S. Pat. No. 4,139,639 to Bahoshy et al. teaches a process of "fixing" aspartame by co-drying (by spray drying or fluid bed coating) a solution containing aspartame and an encapsulating agent, such as gum arabic, to thereby surround and protect the aspartame in the gum during storage. [0010] U.S. Pat. No. 4,384,004 to Cea et al. teaches a method of encap-sulating aspartame with various solutions of encapsulating agents using various encapsulation techniques, such as spray drying, in order to increase the shelf stability of the aspartame. [0011] U.S. Pat. No. 4,634,593 to Stroz et al. teaches a method for producing controlled release sweeteners for confections, such as chewing gum. The method taught therein involves the use of an insoluble fat material which is mix mulled with the sweetener. [0012] Several known compounds have what can be characterized as a "cooling" activity, and are referred to in the art as "physiological cooling agents." Physiological cooling agents are perceived as cold or cool when contacted with the human body and, in particular, with the mucous membranes of the mouth, nose and throat. [0013] Efforts have been directed at perfecting the use of physiological cooling agents within chewing gum formulations to enhance flavor composition and control their release to enhance the flavor of chewing gum. [0014] U.S. Pat. No. 5,326,574 discloses a process for codrying the physiological cooling agent 3-1-menthoxypropane-1,2-diol with a food acceptable, water-soluble carrier and mixing the resulting product into chewing gum. [0015] Peppermint oil is currently used to create a "cooling" in oral products such as toothpaste, mouthwash, chewing gum, candy and other food products. Peppermint oil generally comprises about 45% menthol, about 20% menthone, about 5% menthyl acetate, about 5% eucalyptol and many other constituents. Peppermint oil is even used in non-peppermint products, such as spearmint or wintergreen flavored products, in order to create this desired cooling effect. However, peppermint notes are then found in the resulting non-peppermint flavored products. [0016] Menthol is also known for its physiological cooling effect on the skin and mucous membranes of the mouth. Being a major constituent of peppermint oil, menthol has been used extensively in foods, beverages, dentrifices, mouthwashes, toiletries, lotions and the like. The disadvantages of using menthol, however, are its strong minty odor and the harsh notes it imparts to compositions in which it is found. [0017] A need, therefore, exists for a cooling flavor composition that will contribute a long-lasting cooling sensation to products in which it is found without the unwanted harshness or flavor characteristics that come from adding menthol. [0018] It would be desirable to provide a high flavor impact chewing gum that does not manifest the harsh notes normally associated with some chewing gum. It would also be desirable to provide a clean, high-quality flavored chewing gum with an extended cooling effect. SUMMARY OF THE INVENTION [0019] This invention incorporates a physiological cooling agent, specifically acyclic carboxamide, or combination of physiological cooling agents with acyclic carboxamide, into a chewing gum. One preferred embodiment contains a flavor, and a combination of physiological cooling agents which have been treated so as to modify their release from the chewing gum. The result is a synergy between the physiological cooling agents and the flavor, which provides a high flavor impact at a lower concentration of flavor. Thus, with the aspects of the present invention, chewing gum can be made with a long lasting cooling sensation without unwanted harshness or flavor characteristics. The gum may have a high flavor impact, as well as a clean, high quality flavor with extended cooling effect. [0020] In a second aspect, the present invention also includes a method for producing chewing gum with an acyclic carboxamide physiological cooling agent or combinations of physiological cooling agents with an acyclic carboxamide, treated to have a modified-release. The controlled release of the physiological cooling agent is obtained by modifying the cooling agent by encapsulation, partial encapsulation or partial coating, entrapment or absorption with water-soluble materials or water-insoluble materials. The procedures for modifying the physiological cooling agent include spray drying, spray chilling, fluid-bed coating, coacervation, extrusion, and other agglomerating and standard encapsulating techniques. The cooling agent may also be absorbed onto an inert or water-insoluble material. The cooling agent may be modified in a multiple step process comprising any of the processes noted. [0021] The combination of cooling agents, when modified according to the present invention, give a chewing gum a controlled-release cooling agent. A higher quantity of cooling agents can be used without resulting in a high initial cooling agent impact, but instead having a delayed cooling release in chewing gum, giving a highly consumer-acceptable chewing gum product. Some cooling agents have a very slow release, but may be modified to give a fast release for more initial impact.
