DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
This invention relates to chewing gum. More particularly, it relates to chewing gum which contains erythritol and a moisture binder.
In recent years, efforts have been devoted to replace sugar and sugar syrups normally found in chewing gum with other carbohydrates and noncarbohydrates. Non-sugar or sugar-free chewing gum, which is growing in popularity, uses sugar alcohols or polyols to replace sugar and sugar syrups. The most popular polyols are sorbitol, mannitol and xylitol. New polyols are being developed using new technology to replace these polyols. New polyols have various unique properties which can improve the taste, texture and shelf life properties of chewing gum for consumers. The non-sugar polyols have the advantage of not contributing to dental caries of consumers, as well as being able to be consumed by diabetics.
Many polyols cause gastric distress when consumed in too great of quantities Therefore it would be desirable to use a non-cariogenic sweetener that did not cause gastric distress. Erythritol does not contribute to dental caries, does not significantly contribute to calories and does not cause gastric distress like some other polyols. Thus, this ingredient's use in chewing gum could be a definite improvement.
U.S. Pat. No. 5,120,550 discloses a chewing gum made with a sweetening agent containing erythritol and a liquid sugar alcohol.
EPO Patent Publication No. 0 009 325 and Japanese Patent Publication No. 81-18180 disclose a method of reducing dental caries with a sugarless chewing gum made with erythritol.
Low calorie sweetening compositions containing meso-erythritol are disclosed in U.S. Pat. Nos. 5,080,916 and No. 4,902,525, EPO Patent Publication No. 0 325 790, and Japanese Patent Publications No. 89-225458 and No. 90-104259.
Japanese Patent Publication No. 89-51045 discloses chewing gum made with a melted mixture of meso-erythritol and sugars or sugar alcohols.
EPO Patent Publication No. 0 497 439 discloses a sweetener employing the use of spray dried erythritol.
EPO Patent Publication No. 0 511 761 discloses a sweetening composition made up of erythritol, sorbitol and a glucose oligomer.
PCT Publication No. W093/00828 discloses a stabilized dipeptide sweetening composition which is useful in chewing gum and may contain erythritol.
Other patents and publications which discuss erythritol include Japanese Patent Publications No. 92-287658 and No. 92-287659, both published Oct. 13, 1992, (sweetening compositions containing meso-erythritol); and European Patent Publication No. 0 530 995, published Mar. 10, 1993 (lozenge containing sweetener which is all or partly erythritol or maltitol).
It has been found, however, that using erythritol in chewing gum often causes the gum to be excessively soft, and therefore difficult to form, cut and package. This is especially true as the level of erythritol increases, and especially when the gum contains more than about 2% moisture. Even though erythritol has a low hygroscopicity, and therefore does not cause gum to gain moisture from the atmosphere, the original soft nature of the gum at the time of manufacture also makes the gum undesirable later when it is chewed. It would therefore be a benefit to be able to make chewing gum with erythritol that has increased stiffness to improve processability, especially a gum composition with a high level of erythritol and more than 2% moisture.
SUMMARY OF THE INVENTION
According to the present invention, there is provided a chewing gum composition which contains erythritol and a moisture binding agent. The moisture binding agent acts to tie up moisture present in the gum composition so that the softness imparted by the use of erythritol does not cause the gum to be too soft to wrap. In a first aspect, the invention is a chewing gum composition with increased stiffness to improve processability comprising gum base in an amount from about 5% to about 95% of the gum composition; erythritol in an amount from about 5% to about 95% of the gum composition; a moisture binding ag
