Abstract

Abstract The invention provides a novel chewable pressed tablet containing xylitol and prepared by dry-blending xylitol in an amount of from 10 to 80% by weight and a polyol in an amount of from 10 to 80% by weight and directly compressing the dry-blended admixture.

Description

1~8~0Z4 YD12 The present invention relates to a novel chewable pressed tablet containing xylitol and one or more polyhydric alcohols.
Xylitol is a natural sugar-alcohol known for its use as a sugar substitute r particularly for children, because it is non-cariogenic. Thus, xylitol has been employed as a sugar-substitute in milk chocolate, chewing gum, ice cream, gum-type candies, puddings, jams, jellies, marmalade and the like.
It has also been suggested to use xylitol in pressed tablets. Unfortunately, however, it has been found that xylitol possesses very poor tablettlng characterist:Lcs and there~ore compressed tablets containing the same have never been satisfactorily produced.
The use of sorbitol as a sugar substitute in com- - -pressed tablets is well known. However, the use of sorbitol suffers from the drawback that it forms a very hard tablet which may be too brittle or otherwise undesirable.
It has now been found that chewable pressed tablets containing xylitol as a sugar substitute may be formed in an efficient and economic manner by employing a polyol, such as sorbitol, in combination with the xylitol. Surprisingly, the -pressed tablet formed is softer than and has-improved texture over con~entional pressed tablets containing sorbitol alone as a sugar-substitute. While being harder than a tablet con-taining xylitol alone, the xylitol tablet being too soft and friable to have any practical use.
The present invention provides a dry-blended admixture directly compressed to a chewable tablet, said tablet co]m-prising xylitol in an amount of from about 10 to about 80%

~,' ' ; 1 1~800Z4 by weight of the tablet and a polyol in an amount o~ fromabout 10 to about 80~ by weight.
The present invention further provides a process for preparing a chewable compressed tablet wh:ich comprises dry- -blending xylitol in an amount of from 10 to 80~ by weight and a polyol in an amount of from 10 to 80% by weight and directly compressing the dry-blended mixture into a chewable tablet.
The chewable pressed tablet or pressed mint-type candy of the invention contains xylitol in an amount within the range of from about 10 to about 80%, and preferably from about 20 to about 60~ by weight of the tablet, and a polyol in an amount within the range of ~rom about 10 to about 80%
and preferably ~rom about 20 to about 60% by weight of the tablet. In addition, the tablet may include flavoring, color-; .
ing agents, medicaments, preservatives and the like as will - -be apparent to those skilled in the art.
The polyo~s suitable for use herein include, but are not limited to, sorbitol, mannitol, maltitol and hydrogenated starch hydrolysates, and combinations thereof, with sorbitol , being preferred.
In addition to the xylitol and polyol, the con~ection o~ the invention may include synthetic sweeteners such as sodium saccharin, calcium saccharin, dihydrochalcones, gly-cyrrhizin, glycyrrhizic acid ammonium salt, L-aspartyl-L-phenylalanine (methyl ester), as well as Stevia rebaudiana (Stevioside), Richardella dulcifica (Miracle Berry), Dio-scoreophyllum cumminsii (Serendipity Berry), cyclamates and the like. `

The confection in accordance with the invention may also comprise flavoring agents in an amo~mt of from about 0.01 to about 10~ by weight and preferably ~rom about 0.2 to about 0.25% by weight, e.g., oil of wintergreen, oil of spearmint, oil of peppermint, clove oil, bay oil, anise oil, eucalyptus oil, thyme oil, cedar leaf oil, cinnamon oil, oil of nutmeg, oil of sage, oil of bitter almonds and cassia oil and mixed ~ruit, natural and artificial fruit flavors such as ascorbic acid, citric acid, lactic acid, adipic acid, malic acid and tartaric acid, spice oils, etc. The con~ection may also contain a tableting lubricant, ~uch as calcium stearate or magnesium st0arate.

Xylitol 30-60%
Sorbitol 30-60%
Flavoring 0.01-2%
Lubricant 0.1-3%

Each of the three above compositions was prepared by dry-blending the various ingredients thereof and thereafter directly compressing the dry-blended admixture into a tablet using a conventional tablet press. The tablet in each case was of the same weight and size (thickness). The results obtained are as follows.
The Control A tablet containing only xylitol was extremely friable, very soft and not capable o~ withstanding ; the slightest abuse, such as encountered during conventional packaging procedures.
The Control B tablet containing sorbitol alone was not sweet enough and was extremely hard and unsuitable as a chew-able tablet.
