摘要:
A method for producing a chewing gum with a controlled release active agent, as well as the chewing gum so produced, is obtained by physically modifying the release properties of the active agent, such as a nutraceutical or nutritional supplement, by coating and drying. The active agent is coated by encapsulation, partially coated by agglomeration, entrapped by absorption, or treated by multiple steps of encapsulation, agglomeration, and absorption. The coated active agent is preferably then co-dried and particle sized to produce a release-modified active agent for use in chewing gum. The active agent may also be used in a coating on a chewing gum product, as part of a rolling compound applied to the chewing gum product, or as a part of the liquid in a liquid-center chewing gum product.

A method for producing a chewing gum with a controlled release of caffeine, as well as the chewing gum so produced, is obtained by physically modifying caffeine's properties by coating and drying. Caffeine is coated by encapsulation, partially coated by agglomeration, entrapped by absorption, or treated by multiple steps of encapsulation, agglomeration, and absorption. The coated caffeine is then co-dried and particle sized to produce a release-modified caffeine. When incorporated into the chewing gum, these particles are adapted to produce a fast release or a delayed release when the gum is chewed.
摘要:
A method for producing a chewing gum with an improved release of active agent, as well as the chewing gum so produced, is obtained by adding an active agent to a chewing gum coating. The active agent is added to the coating in a coating solution or premixed with a flavor or solvent. The coating solution may contain sweetener or other transdermal enhancing agents to obtain increased transmucosal absorption. An active agent may also be used in the gum core.
摘要:
A method for producing a chewing gum with a controlled release of a bitterness inhibitor, as well as the chewing gum so produced, is obtained by physically modifying the release properties of the bitterness inhibitor by coating and drying. The bitterness inhibitor is coated by encapsulation, partially coated by agglomeration, entrapped by absorption, or treated by multiple steps of encapsulation, agglomeration, and absorption. The coated bitterness inhibitor is preferably then co-dried and particle sized to produce a release-modified bitterness inhibitor for use in chewing gum. When incorporated into the chewing gum, these particles are adapted to produce a fast release or a delayed release when the gum is chewed. The preferred bitterness inhibitor is sodium gluconate.
摘要:
A chewing gum including sorbitol and method of making the same is provided. The chewing gum is created from a formulation that includes a composition that comprises a syrup solution of aqueous sorbitol, a plasticizing agent selected from glycerin, propylene glycol and mixtures thereof, and an anticrystallization agent comprising alditols other than sorbitol having a degree of polymerization (DP) of 1 or 2.
摘要:
A dual composition hard coated chewing gum is provided, which exhibits improved long-term shelf stability under storage conditions involving constant exposure to the moisture contained in the atmosphere. The dual composition hard coated chewing gum is ideally suited for pellet chewing gum having pellet shapes which cannot be easily protected from atmospheric moisture by packaging. The dual composition hard coated chewing gum has a gum center which includes a gum base, a bulk portion and one or more flavoring agents. The dual composition hard coated chewing gum also has an outer coating which includes layers which contain from about 50 to about 100% of at least two different polyols preferably lactitol, maltitol, hydrogenated isomaltulose or erythritol. A method of preparing the dual composition hard coated chewing gum is also provided. Lactitol, maltitol or hydrogenated isomaltulose is preferably applied first, and the covered with an erythritol coating.

The dual composition hard coated chewing gum also has an outer coating which includes layers which contain from about 50 to about 100% xylitol; and layers which contain from about 50 to about 100% of a non-xylitol polyol (preferably lactitol, maltitol or sorbitol, with lactitol and maltitol being particularly preferred). A method of preparing the dual composition hard coated chewing gum is also provided. The non-xylitol polyol is preferably applied first, and covered with a xylitol coating.
摘要:
An aqueous syrup for use in chewing gum, particularly pellet gum, comprises, on a dry basis, greater than about 98% polyols, of which i) about 50% to about 90% is sorbitol, ii) about 3% to about 30% is maltitol, iii) about 2% to about 20% are polyols, other than sorbitol and maltitol, with a degree of polymerization (DP) of 1 or 2, and iv) less than about 20% (and perhaps less than about 12%) are polyols with a DP of 3 or greater. The syrup is made with less than about 1.0% plasticizing agent, such as glycerin or propylene glycol. The syrup contains less than 5% water. The syrup can be made by evaporating a mixture of a sorbitol solution, a maltitol syrup and one or more polyols selected from the group consisting of mannitol, xylitol, lactitol, erythritol, hydrogenated isomaltulose, and combinations thereof. Methods of using the syrup to make chewing gum, and chewing gum products containing the syrup are also provided.
摘要:
An apparatus (10) for the controlled heating of fluid comprises a general elongated electrically heating core (16) with an exterior surface (36) formed of a material having a high thermal conductivity and frustoconically shaped to slidingly receive an assembly (14) so that the assembly envelops the surface along at least a portion of the length of the core. The assembly (14) forms a sealed passageway (46) for generally unidirectional sheet-like flow upward along the core (16). A control system (20) selectively operates the heating core (16) so that the fluid, under varying flow rates, is warmed to a desired temperature without overheating, before the fluid flows from the passageway (46).
