Packaging materials and packages that transfer fragrances to foods and
other products via the vapor phase are disclosed. The present invention
provides a source of desired fragrance, a suitable environment for vapor
transfer, and an appropriate food substrate to which flavor and fragrance
is added. Examples of the source of fragrance can be a packaging film
containing fragrance, a sachet of absorbed flavor material, a tape or
label applied to the inside of a package, and a flavor diffusing granule
or an active system for delivering flavor vapor to the environment.
Materials that are preferably treated using the present invention include
snacks, confections, baked goods, fresh plant materials, cereals and
beverages, as well as non-food products. The time required for flavor
transfer is dependent primarily on the volatility and concentration of
the fragrances, absorptive capacity of the food, and the intensity of the
flavor desired.
