Compositions or spices in the form of leaves, powders or particles are flavored with an emulsion containing an active volatile flavoring substance by directly spraying the exposed surface with the emulsion comprising the flavoring substance mixed with a solid film-building vehicle and an emulsifying agent.A flavoring process of this kind is particularly suitable for flavoring tea or products for preparing infusions or decoctions or spices, or for perfuming solid materials used for packaging.
