  • Patent number: 6740332
    Abstract: Improved edible films for mucoadhesion are provided. The films include at least three types film forming agents other than pullulan, such as maltodextrins, hydrocolloids and fillers. Preferably, the maltodextrin has a dextrose equivalent of less than 20. Medicaments and other additive agents can also be incorporated into the edible films. In this regard, the edible films can be utilized to deliver or release the medicaments into an oral cavity, thereby providing effective oral treatment with respect to, for example, oral cleansing and breath freshening.

  • Publication number: 20020131990
    Abstract: Improved and inexpensive pullulan free edible film formulations and methods for making the same are provided. The edible pullulan free film compositions comprise effective amounts of at least one film forming agent; at least one bulk filler agent; at least one plasticizing agent; and optionally at least one thickening agent. Medicaments and other additive agents can also be incorporated into the edible films. The present invention further provides methods of delivering a medicament, treating halitosis, treating xerostomia, and treating plaque or gingivitis using the pullulan free edible film compositions.

  • Patent number: 5538741
    Abstract: A sugarless non-tack chewing gum having excellent cohesive properties and flavor is prepared using a non-tack gum base which is typically less cohesive or even crumbly. The lack of cohesiveness in the gum base is overcome by adding, to the chewing gum, a syrup blend including glycerin with evaporated hydrogenated starch hydrolysates and water. The syrup blend is preferably prepared by coevaporating a mixture of glycerin with a conventional aqueous hydrogenated starch hydrolysate solution, in order to remove much of the water. The syrup blend acts as a binder for the gum base and chewing gum ingredients without causing the gum to adhere to teeth and dentures.

  • Patent number: 4938971
    Abstract: Fruit juices are concentrated to low moisture levels (below about 25 percent, and preferably as low as about 2 percent moisture content) without excessive increases in viscosity or loss of flavor by adding an edible plasticizer such as glycerin, propylene glycol or a mixture thereof, to a fruit juice or fruit juice concentrate, and evaporating most of the moisture from the concentrate-plasticizer mixture. The resulting fruit juice solids-plasticizer mixture can be used as an additive for chewing gum, foods, or concentrated fruit juice compositions for reconstitution in water to form beverages.
