The following invention relates to edible compositions having a unique, long lasting, cooling perception which provides the user with an enhanced perception of breath-freshening without bitterness. The following invention is useful in chewing gum compositions and confectionary compositions which provide a long-lasting, breath freshening perception without bitterness.
Cooling agents are describes as chemical compounds providing cold or cool sensations when contacted with the human body, especially with the mucus membranes of the mouth, nose and throat. Cooling compounds are widely used in edible products, beverages, dentifrices, tobacco products, mouthwashes and toiletries.
One class of cooling compounds which are very effective compounds containing an N-substituted p-menthane carboxamide moiety. Examples of these compounds are described in, for example, British Patents GB 1,351,761-2 and U.S. Pat. No. 4,150,052.
Properties of those compounds are based on l-menthol, which is one of the most well-known physiological coolants, and which has been widely used in several applications. L-menthol has an excellent cooling strength and is relatively inexpensive.
It is well recognized that one of the purpose of chewing gum and confectionery products is to enhance ones breath and provide a clean, cool, fresh feeling in the mouth. Unfortunately, most products are not able to maintain such perception for long periods of time, which is a time up to about thirty minutes.
The compound of the present invention may be used alone or in combination with additional compounds or composition which increase cooling and flavor impact and extend these taste effects over a prolonged period of time.

When the carrier is an emulsion, the flavoring composition can also contain emulsifiers such as mono- and diglycerides or fatty acids and the like. With these carriers or vehicles, the desired physical form of the compositions can be prepared.
The quantity of Structure I utilized should be sufficient to impart the desired flavor characteristic to the product, but on the other hand, the use of an excessive amount of Structure I is not only wasteful and uneconomical, but in some instances, too large a quantity may unbalance the flavor or other organoleptic properties of the product consumed. The quantity used will vary depending upon the ultimate foodstuff; the amount and type of flavor initially present in the foodstuff; the further process or treatment steps to which the foodstuff will be subjected; regional and other preference factors; the type of storage, if any, to which the product will be subjected; and the preconsumption treatment such as baking, frying and so on, given to the product by the ultimate consumer. Accordingly, the terminology effective amount and sufficient amount is understood in the context of the present invention to be quantitatively adequate to alter the flavor of the foodstuff.
It will be understood that the embodiments described herein are merely exemplary, and that one skilled in the art may make variations and modifications without departing from the spirit and scope of the invention. All such variations and modifications are intended to be included within the scope of the invention as described hereinabove. Further, all embodiments disclosed are not necessarily in the alternative, as various embodiments of the invention may be combined to provide the desired result.
The 4-aminophenylacetamide used in this example was obtained according to patent literature WO 02/08247 A2 or WO 03/051909 A2. Procedure was as follows: Methanol (200 mL) was charged to 4-aminophenylacetic acid (Aldrich) (25 g, 0.165 mol). Sulfuric acid (18 mL concentrated, 0.648 mol) was added maintaining the temperature <20° C. The mixture was then refluxed for one hour and concentrated by distillation at atmospheric pressure until the volume of 140 mL. The mixture was then cooled to 50° C. and tert-buthyl methyl ether (300 mL) was added maintaining the temperature above 45° C. The mixture was gradually cooled to 0-5° C. and held at this temperature for 1 hour. The resultant crystalline product was isolated by filtration and washed with cold methanol: tert-butyl methyl ether (20 mL: 55 mL) and cold tert-butyl methyl ether and then dried under vacuum to give methyl 4-aminophenylacetate hydrogensulfate (35.3 g, 80% yield).
Obtained compound was added to 20% w/w aqueous NaCl (65 mL). Aqueous ammonia (90 mL), containing dissolved sodium chloride (15 g) was added maintaining the temperature 15-25° C. The mixture was then stirred for 16 hours at 22° C. The mixture was cooled to 0-5° C. and held at this temperature for one hour. The resultant crystalline product was isolated by filtration, washed with water (2×30 mL) and dried under vacuum at 45° C. giving 13.6 g of product, 68% yield.
The p-Menthane-3-carboxylic acid (obtained according to publication: Desmond Cunningham, Eva T. Gallagher, David H. Grayson, Patrick J. McArdle, Christina B. Storey, Deborah J. Wilcock; J. Chem. Soc., Perkin Trans. 1, 2002, 2692-2698), (2.5 g, 13.5 mmol) was heated under reflux with thionyl chloride (Alfa Aesar) (7 mL) for three hours. Then the excess of thionyl chloride was distilled off in vacuo. Residue was dissolved in CH2Cl2 (30 mL). This solution was added drop wise to the mixture of 4-aminophenylacetamide (2.2 g, 13.5 mmol) and triethylamine (1.8 g, 17.8 mmol) at 0° C. After ten minutes the solution was allowed to warm to room temperature. After 1 hour GC showed that reaction is completed. CH2Cl2 (50 mL) was added to the reaction and this mixture was washed by 0.1 N HCl aq, water, 0.1 N NaOH aq, by brine and dried over MgSO4. The mixture was then filtrated and evaporated give white solid which was crystallized from hot ethyl acetate providing 3 g (65%) product as white solid.

At the level of 10 ppm in water this material contributes moderate throat and mouth cooling that lingers with some bitter notes in background. Cooling lasts with breath in for 30 minutes.
At the level of 1 ppm in water Structure I is clean with slight cooling up front that builds with time to moderate level. Cooling lasted for 30 minutes.
The following gum base formulation was prepared:
The cherry flavor is commercially available from IFF. The gum base, Hades-T is commercially available from Cafosa Gum, Barcelona Spain.
Structure I by itself and in separate mixtures with monomenthyl glutarate, 2-isopropyl-N,2,3-trimethylbutyramid, N-ethyl-p-menthanecarboxamide and menthyl acetoacetate at levels detailed in the Tables below was blended with the gum base in a Sigma mixer. The resultant chewing gum blend was then manufactured into strips 1 inch in width and 0.1 inches in thickness. These strips were cut into lengths of 3 inches each. A control gum, without any coolers, was also manufactures into strips and this control gum exhibited a flavor without imparting any cooling effect.
The resulting gum blends had a substantially identical to the taste profile of the control gum; however the gum blends had cooling effects as described below.
Samples were profiled by a highly trained descriptive analysis panel. The ballot consisted of the following terms: Total impact, total mint, cooling-mouth closed, cooling-breath in, nasal cooling—breath in, throat irritation, bitterness, tongue irritation, numbing. Each attribute was rated at discrete time points including 5 secs, 30 secs, 90 secs, 3 mins, 5 mins, 7 mins, 10 mins, 15 mins, 20 mins, and 30 mins.
