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

[0020] The coating process may be repeated as many times as needed in order to obtain the desired thickness of the coating. In the coating process, the active substance(s) in solid form may be added between one or more of the ordinary coating processes. The last layer of the coating process may also include the active substance(s) in solid form. It is also within the present invention to use different active substances in solid form in the same coating layer or use one active substance in one layer, and a second active substance in another layer. Such combinations of active substances may be flavour and high potent sweeteners or a medicament together with an substance decreasing an undesirable taste of the medicament.

[0021] As the active substance(s) is / are located in the outer part of the coating, the active substance(s) is / are exposed to the consumer within a short period of chewing. Accordingly, in a further embodiment, the invention relates to the use of one or more active substance(s) in solid form in the coating of a coated chewing gum in order to obtain a fast onset of the effect.

[0022] A further advantage of the admixture of the active substance(s) in solid form is that the solid form is more resistant to decomposition. Accordingly, the invention also relates to the use of one or more active substance(s) in solid form in the coating of a coated chewing gum in order to obtain a better stability of the active substance(s).

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.
