Coated chewing gum comprising an active substance having local activity

Abstract

A coated chewing gum comprising a core of chewing gum and a coating comprising a coating material and one or more active substance(s) in solid form. The use of an active substance in solid form in the coating of a coated chewing gum provides a fast onset of the effect, a better stability of the active substance, and an increased effect thereof in al chewing phases.

Description

TECHNICAL FIELD [0001] The present invention relates to a coated chewing gum comprising a core of chewing gum and a coating comprising a coating material as well as one or more active substance(s) in solid form. Furthermore, the invention relates to a method for the preparation of a coated chewing gum and the use of one or more active substance(s) in solid form in the coating of a coated chewing gum. TECHNICAL BACKGROUND [0002] Coated chewing gum is prepared by coating a core of chewing gum with a number of layers of coating. The coating most often takes place in rotating coating kettles in which cores of chewing gum are rotated and coating suspension is applied in small portions that disperse evenly over the surfaces of the cores. Subsequently, the coated cores are dried by means of air. [0003] These coating operations may be applied in up to approx. 90 increments until the preferred coating thickness is obtained, and the product has the preferred measures and the preferred weight....

AI Technical Summary

Benefits of technology

"The invention is about a coated chewing gum with a solid active substance added to the coating. The process involves preparing a core of chewing gum, preparing a coating suspension, applying the coating suspension to the core, adding one or more active substances in solid form, and optionally adding liquid active substances and a surface layer. The active substance is added without drying the coating, and the thickness of the coating can be adjusted by repeating the process. The active substance is exposed quickly to the consumer during chewing, and the solid form is more resistant to decomposition. The use of solid active substances also provides better stability and an increased effect in all chewing phases."

Problems solved by technology

This causes the chewing gum to gradually lose its flavour, ethereal oils, if any, are oxidised, and the chewing gum loses moisture and gets harder.

Furthermore, the use of active substances in liquid form in the coating layers has the disadvantage that some of the active substances are lost to the surroundings during the coating process.
