  • 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: 20020037340
    Abstract: A method for producing a chewing gum with an improved release of a lipophilic active agent, as well as the chewing gum so produced, is obtained by using a hydrophilic gum base. The preferred and novel gum base includes hydrophilic polymers, hydrophilic softeners/emulsifiers and fillers, but is essentially free of hydrophobic elastomers and hydrophobic softeners, as well as waxes and elastomer solvents. The lipophilic active agent is preferably added to a coating on a chewing gum pellet made using a hydrophilic gum base, such as by being mixed into a coating solution. The coating solution may contain a high-intensity sweetener. An active agent may also be used in the gum core.
