[0046] Table 1 below shows the test results of gel capsules containing fragrance material according to the present invention, and the comparative results of otherwise identical gel capsules without a second protective coating on the surface of the gel capsules.

The storage conditions were the same in each case, 90% relative humidity and at 25°C. Fragrance intensity was judged by rupturing or breaking open the gel capsule, releasing the fragrance material from the then remaining delivery system gel capsule.

Abstract

Gelatin capsules encapsulating an aroma material including at least one aroma compound may be applied to product packaging, such as food packaging, container (100) etc., with a secondary protective coating, e.g., at the interface of a container and its closure device. The gelatin capsules can be ruptured or broken when the container is opened, thereby releasing the aroma compound and causing a favorable aroma for the consumer. The secondary protective coating can reduce or prevent degradation of the gelatin capsules during product packaging, transport, and storage, thereby enhancing their performance.
