Filed:

Mar 31, 2000

Appl. No.:

09/540383

Inventors:

Joo H. Song - Chicago IL
Donald J. Townsend - Moores Hill IN
James R. Maxwell - Chicago IL

Assignee:

Wm. Wrigley Jr. Company - Chicago IL

International Classification:

A23G 330

US Classification:

426 3, 426650

Abstract:

The present invention provides methods and compositions for improving the flavor duration in chewing gum. In a preferred form, the present invention provides matrix compositions comprising a hydroxypropylcellulose cross-linked with a multi-functional carboxylate to yield a matrix having a lower water solubility than the original cellulosic material. This matrix may be ground up, have a flavor incorporated therein and used in gum compositions in which it facilitates a prolonged release of the flavoring.

Assignee:

Wm. Wrigley Jr. Company - Chicago IL

International Classification:

A23G 330

US Classification:

426 3, 426 5, 426 6

Abstract:

A method is provided for the total manufacture of chewing gum on a continuous basis without requiring the separate manufacture of chewing gum base. The method uses a continuous high efficiency mixer which is configured for the total manufacture of a wide variety of chewing gum products and includes at least one large feed port that is not adjacent a conveyor element. By integrating the manufacture of chewing gum into a single operation, the method of the invention can save time and labor, and improve product consistency.

International Classification:

A23G 330

US Classification:

426 5, 424 48, 424440

Abstract:

A method for producing a coated chewing gum with a controlled release of an active agent, as well as the chewing gum so produced, is obtained by physically modifying an active agents properties by coating and drying. An 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 then co-dried and particle sized to produce a release-modified active agent. When incorporated into a chewing gum coating, these particles release into the mouth but mask bitter and other off-tastes in the mouth, and are readily ingested.

US Classification:

426 5, 424 48, 424440

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.

International Classification:

A23G 330

US Classification:

426 3, 426 6

Abstract:

The present invention includes a method for producing a chewing gum with a modified release sweetener selected from the group of N-substituted derivatives of aspartame, particularly neotame, as well as the chewing gum so produced. The modified release neotame or other N-substituted derivative of aspartame sweetener is obtained by physically modifying the sweetener properties by coating and drying. Neotame or another N-substituted derivative of aspartame sweetener is coated by encapsulation, partially coated by agglomeration, entrapped by absorption or extrusion, or treated by multiple steps of encapsulation, agglomeration, absorption, or extrusion. The coated sweetener is then co-dried and particle sized to produce a release-modified high-intensity sweetener. When incorporated into the chewing gum, these particles are adapted to enhance the shelf stability of the sweetener and/or produce a modified release when the gum is chewed.

US Classification:

426 3, 424 48, 424440, 426 5

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.
