Description

RELATED APPLICATION

[0001] This application claims priority to Indian Application No. 543/CAL/02, filed Sep. 17, 2002, entitled “Gum Based Chewing Product,” which is incorporated herein by reference in its entirety.

FIELD OF INVENTION

[0002] The present invention relates to a gum based product and a process for manufacturing the same. More particularly the invention relates to a gum based product with a synthetic or natural betel nut source, especially a chewing/bubble gum containing an alkaloid-like composition, such as nicotine or other such alkaloids like caffeine, theine etc. from natural or synthetic origin for its source, with or without taste enhancers and a process for preparing the same.

BACKGROUND

[0003] Tobacco flavored chewing gum or chewing gum containing tobacco, which simulates chewing tobacco are known in the art and have been described in U.S. Pat. Nos. 3,877,468; 5,488,976; 4,317,837; 4,802,498; 4,093,752; 3,845,217; 865,026 and 904,521.

[0004] This tobacco-flavored chewing gum is usually recommended for smokers as a substitute for smoking tobacco. U.S. Pat. Nos. 3,877,468 and 5,488,962 disclosed chewing gum having variable amounts of nicotine. U.S. Pat. Nos. 4,317,837 and 4,802,498 describe chewing gum wherein tobacco rather than nicotine is added to chewing gum. U.S. Pat. No. 4,093,752 employs tobacco flavorings such as 2,4,6-triisobutyl 1-1,3,5-trioxane and U.S. Pat. No. 3,845,217 employs buffered nicotine in chewing gum. Further mixtures of tobacco and wax are used in U.S. Pat. Nos. 865,026 and 904,521. The tobacco flavorings may be employed along with non-sweet taste or flavorings such as salt, pepper, sour, bitter, meaty, with or without sweetness as desired.

[0005] In the tropical Asian countries, chewing betel nut and tobacco in the form of areca quid is quite popular. This type of Areca quid mainly consists of Areca nut (betel nut), lime paste (in India known as chuna), a resinous extract from the matrix of Acacia tree (in India known as Kattha or catechu). All these are spread over betel leaf and the whole quid is consumed along with the betel leaf, which is known as ‘pan’ in India.

[0006] The consumption of betel nut and tobacco together in the form of Areca quid has many disadvantages like:

[0007] i. it generates a bright thick red colored fluid which mixes with the saliva and has to be expectorated and causes pollution of the environment;

[0008] ii. this type of Areca tobacco mixture mostly contains alkaline lime, which in long use could result in oral cancer; and

[0009] iii. long use of such Areca/tobacco mixtures cause contraction of oral tissue which results in incapability of opening the mouth fully.

[0010] To overcome these Indian Patent No. 187110 granted to the applicant herein describes use of quimam and betel nut in chewing gum.

SUMMARY OF INVENTION

[0011] The present invention is an improvement over Indian Patent No. 187110. It delivers nicotine source, prepared in a particular method, at a level of 1 mg to 12.6 mg per chewing gum and has a better mixing capacity with the gum base. Moreover as the per chewing gum dose of nicotine is limited and can be chewed for a longer time a sustained effect is achieved though the overall consumption of nicotine is less. Moreover the product smoothness is much higher as well as saliva generation in the present chewing gum is much lesser. Further the incorporation of taste enhancers selected from catechu and or lime along with the betel nut and nicotine source provides a better overall taste and chewing property along with improved product smoothness and feel attributes. It provides further a longer lingering effect causing reduction in intake of nicotine per day.

EXAMPLE 7

[0202] Composition of Chewing Gum:

[0203] The composition of chewing gum is as follows:

[0204] Gum base 34.0% by weight

[0205] Dough forming medium (liquid glucose) 18.2% by weight

[0206] Nicotine source 3.2% by weight

[0207] Filler (powdered sugar) 32.9% by weight

[0208] Betel nut powder (45 &mgr;m to 710 &mgr;m) 4.4% by weight

[0209] Taste enhancer no. 1 (catechu) 1.0% by weight

[0210] Taste enhancer no. 2 (lime) 0.5% by weight

[0211] Sweetening agent (Mannitol or any other material providing required sweetness) 5.55% by weight

[0212] Peppermint 0.5% by weight and/or other flavoring and mixing the composition thoroughly.

[0213] Preparation of Chewing Gum:

[0214] To prepare the chewing of this composition the following process is followed:

[0215] i) mixing chewing gum base, dough forming medium, taste enhancer no. 1 i.e. catechu and taste enhancer no. 2 i.e. lime, a portion of filler, betel nut powder and sweetening agent;

[0216] ii) heating the above mixture at 55° C. to soften the gum base to form a dough;

[0217] iii) adding the nicotine source prepared by the method as described above to the dough and reheating the dough for uniform mixing of the nicotine source in the dough;

[0218] iv) adding peppermint and any other flavoring agent and mixing thoroughly;

[0219] v) gradually adding the remaining portion of filler to obtain the chewing gum mass;

[0220] vi) spreading the said chewing gum mass in the form of a sheet of uniform thickness and cut into rectangular or any other shaped pieces. The cut pieces are wrapped in wax paper/aluminum foil for airtight packing. The nicotine source used will deliver 1.0 mg to 12.6 mg of nicotine per dose i.e. per piece of chewing gum.

[0221] To make an evaluation of the product according to the present invention chewing gum prepared by the process of examples 1, 2, 3, 4, 5, 6 and 7 a control sample A was prepared by the method as follows:

[0222] 20.8 gm of chewing gum base, 20.8 gm of liquid glucose, 24.55 gm of powdered sugar and 4.4 gm of betel nut powder are mixed together, and the mixture is heated at 65° C. to soften the gum base to form dough;

[0223] 4.4 gm of quimam is added to the dough and reheating the dough for uniform mixing of the quimam and dough;

[0224] 0.5 gm of peppermint is added and mixed thoroughly; and

[0225] a further amount of 24.55 gm of powdered sugar is added gradually to the mixture to obtain the chewing gum mass.

[0226] The chewing gum mass in the form of a sheet of uniform thickness is cut into rectangular or any other shaped pieces. The cut pieces are wrapped in wax paper/aluminum foil for airtight packing.

[0227] The evaluation was made taking the factors of product smoothness, saliva generation per dose, lingering effect, nicotine intake/day, chewing property, overall taste. A panel of 10 nicotine consumers with intake of nicotine between 70 to 105 mg of nicotine per day divided into 10 to 12 doses through various nicotine containing products other than smoking were used for the purpose of evaluation.

[0228] The chewing gum of the present invention as in examples 1, 2, 3, 4, 5, 6 and 7 are compared with the control example A for the following attributes: 5 EXAMPLE EXAMPLE EXAMPLE EXAMPLE EXAMPLE EXAMPLE EXAMPLE EXAMPLE ATRRIBUTES 1 2 3 4 5 6 7 A 1 PRODUCT 90   78   87   84   92   75   92   60   SMOOTHNESS 2 SALIVA 8.0 cc 9.0 cc 10.0 cc 10.0 cc 7.5 cc 6.8 cc 7.0 cc 15.0 cc GENERATION 3 LINGERING 120 95 110 110 125 125 135 90 EFFECT MINUTES MINUTES MINUTES MINUTES MINUTES MINUTES MINUTES MINUTES 4 NICOTINE 52.5 mg 61.9 mg 57.3 mg 58.7 mg 49.9 mg 49.9 mg 46.2 mg 70.0 mg INTAKE/DAY 5 CHEWING 8.3 7.95 8.1 8.15 8.8 8.2 8.5 7.9 PROPERTY 6 OVERALL 8.2 8.4 8.6 8.75 9.0 7.9 9.2 8.15 TASTE

[0229] Product Smoothness

[0230] 1—Product Smoothness is an attribute that is related to the degree at which the nicotine is absorbed into the system giving the user the feel. On a scale of 100, example 1 delivers a smoothness of 90, example 2 a smoothness of 78, example 3, 4, 5, 6, and 7 delivers a smoothness of 87, 84, 92, 75, and 92 respectively which is much higher than that delivered by control example A, which delivers a smoothness of 60. Thus the gum based product with nicotine source without taste enhancer is better in respect of this attribute to that with quimam while that with both taste enhancers gives the best result.

[0231] Saliva Generation

[0232] 2—Saliva Generation is the saliva formed during intake of the chewing gum. Example 1 leads to saliva generation of 8.0 cc, examples 2 to 7 saliva generate 9 cc, 10 cc, 10 cc 7.5 cc, 6.8 cc and 7.0 cc, which are much lower than that by control example A which is 15.0 cc. Hence there is less saliva generation in the product with nicotine source without taste enhancer while those with both taste enhancers lead to least saliva generation.

[0233] Lingering Effect

[0234] 3—The lingering effect is the time interval when the user feels the urge to take another dose of nicotine product. The effect of the chewing gum lingers for 120 minutes in example 1, 95 minutes for example 2, 110 minutes for example 3 and 4, 125 minutes for examples 5 and 6, 135 minutes for example 7, which are much higher than the control example A where effect lingers for only 90 minutes.

[0235] The lingering effect being higher for the examples 1, 2, 3, 4, 5, 6, and 7 the intake of chewing gum and in the effect nicotine intake per day are less than the control example A. The values of nicotine intake/day being 52.5 mg in example 1, 61.9 mg in example 2, 57.3 mg in example 3, 58.7 mg in example 4, 49.9 mg in examples 5 and 6, 46.2 mg in example 7, while it is 70 mg in example A.

[0236] Chewing Property & Overall Taste

[0237] Chewing property and overall taste were determined in a scale of 10. Example 1 to 7 revealed values 8.3, 7.95, 8.1, 8.15, 8.8, 8.2 and 8.5 respectively as against 7.9 for example A with respect to Chewing property whereas for Overall Taste the values were 8.2, 8.4, 8.6, 8.75, 9.0, 7.9 and 9.2 for examples 1 to 7 as against 8.15 for example A.

[0238] Thus considering all aspects of the experiments done, it is found that betel nut containing chewing gum with nicotine source of the present invention is superior to the control sample. The chewing gum with nicotine source along with both taste enhancers namely catechu and lime, gives a better result than the gum without taste enhancers with respect of the attributes tested.

[0239] The gum-based product of the present invention may be used for other applications by incorporating appropriate actives such as caffeine and other alkaloids together with suitable additives.
