DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates generally to chewing gum. More specifically the present invention relates to improved formulations for chewing gum and gum bases.
It is of course known to construct chewing gum from a water insoluble gum base and a water soluble portion along with flavor(s). Gum base is designed to be retained in the mouth throughout the chewing period The water soluble portion and flavors are designed to dissipate during chewing.
Insoluble gum base generally comprises elastomers, resins, fats and oils, softeners, and inorganic fillers. The elastomers can include either synthetic elastomers or natural elastomers. Natural elastomers include natural rubber. Synthetic elastomers include polyisobutylene, isobutylene-isoprene copolymers, styrene-butadiene copolymers, polyvinyl acetate, polyisoprene, polyethylene, vinyl acetate - vinyl laurate copolymers, and combinations thereof.
It is also known to use in gum base elastomer plasticizers. Such elastomer plasticizers can include natural rosin esters as well as other elastomer plasticizers. Additionally, chewing gum base can include filler/texturizers and softener/emulsifiers. Softeners optimize the chewability and mouth feel of the chewing gum. Softener/emulsifiers that are typically used include tallow, hydrogenated tallow, hydrogenated and partially hydrogenated vegetable oils, cocoa butter, glycerol monostearate, glycerol triacetate, lecithin, and combinations thereof.
In addition to a water insoluble gum base portion, a typical chewing gum composition includes a water soluble portion and one or more flavoring agents. The water soluble portion can include bulk sweeteners, high intensity sweeteners, flavoring agents, softeners, emulsifiers, colors, acidulants, fillers, antioxidants, and other components that provide desirable attributes.
SUMMARY OF THE INVENTION
The present invention provides improved chewing gum formulations and bases, as well as methods of producing chewing gum and bases. Pursuant to the present invention chewing gum and gum bases that include edible polyesters are provided. In this regard, traditionally used elastomers and elastomer plasticizers can be replaced with edible polyesters.
To this end the present invention provides, in an embodiment, a gum base including at least one edible polyester that is produced through a reaction of at least one alcohol chosen from the group consisting of glycerol, propylene glycol, and 1,3 butylene diol, and at least one acid chosen from the group consisting of citric acid, fumaric acid, adipic acid, malic acid, succinic acid, suberic acid, sebacic acid, dodecanedioic acid, glucaric acid, glutamic acid, glutaric acid, azelaic acid and tartaric acid.
In an embodiment, the base is wax-free.
In an embodiment, the base is non-tacky.
In an embodiment, the base is a bubble gum-type base.
In an embodiment, the edible polyester comprises approximately 1% to about 80% by weight of the base.
In another embodiment, the present invention provides a gum base including at least approximately 1% by weight of an edible polyester that is a product of a condensation reaction of at least one alcohol chosen from the group consisting of trihydroxyl alcohol and dihydroxyl alcohol, and at least one acid chosen from the group consisting of dicarboxylic acid and tricarboxylic acid.
In a further embodiment, the present invention provides a chewing gum formulation comprising an insoluble gum base, a water soluble portion, a flavor, and at least 0.1% by weight of an edible polyester. The edible polyester is produced by the reaction of at least one alcohol chosen from the group consisting of glycerol, propylene glycol, and 1,3 butylene diol and at least one acid chosen from the group consisting of citric acid, fumaric acid, adipic acid, malic acid, succinic acid, suberic acid, sebacic acid, dodecanedioic acid, glucaric acid, glutamic acid, glutaric acid, azelaic acid and tartaric acid.
In an embodiment, the formulation includes a bulk sweetener.
In an embodiment, the formulation includes a
