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, 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.
A method of transferring a fragrance to a product comprising the steps of:
A packaging material comprising at least one polymer layer and at least one fragrance in an amount sufficient to diffuse within the interior of a package made from the packaging material under normal conditions of temperature and pressure.
A product package comprising a package, and a product contained within the package, and further comprising a material impregnated with a fragrance in contact with said product.
Apparatus for adding a fragrance to a product comprising a source of gas flow containing a fragrance wherein the fragrance is transferred to a product within the chamber by contacting the product with the gas flow.
