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.
