  • Publication number: 20150004281
    Abstract: Low density chewing gums having a density of less than 0.60 g/cc comprise at least 50% polymer and less than 40% bulking agent and filler combined. The low density chewing gum may be produced by mixing the ingredients with supercritical fluid carbon dioxide and cooling the mixture. The mixture may optionally be cut into pieces and coated.

  • Publication number: 20090202673
    Abstract: A chewing gum composition contains a gum base; 0% to about 60%, preferably about 10% to about 50%, bulking and sweetening agents; and about 5% to about 80% fat-containing confection, such as chocolate. The gum base comprises about 2% to about 40% elastomer, about 10% to about 50% elastomer plasticizer, about 2% to about 35% gum base softener, and about 1% to about 10% emulsifier. The gum base usually contains less than 10% filler, and less than 45% gum base matrix disrupting materials. In another embodiment, the chewing gum product is made from gum base and flavoring agents, possibly without the addition of any bulk sweetening agents. A chewing gum product can be formed from the composition. The product may be a compressed gum product. In another embodiment, the product can be coated or filled with a fat-containing confection, such as chocolate, in which case the product may be made of a composition without the fat-containing confection in it and with 0% to about 60% bulking and sweetening agent.

  • Patent number: 6949264
    Abstract: 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.

  • Publication number: 20050163886
    Abstract: Methods for manufacturing coated confectionary or chewing gum products are provided. The method of manufacturing a confectionary product comprises the steps of providing a confectionary center, heating at least one polyol to the polyol's melting point to produce a molten polyol, spraying the molten polyol through at least one atomizing spray nozzle, and applying a plurality of layers to the confectionary center to form a final coating. The plurality of layers includes at least one layer of the molten polyol.

  • Patent number: 6627234
    Abstract: 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.
