Abstract
Abstract An aqueous mixture containing water soluble or dispersible solids is freeze dried to form porous solids particles. The particles are impregnated with liquid aromatic materials such as essential oils, flavoring oils, or perfumes. The impregnated particles are coated with a film-forming material to seal the liquid within the interstices of the solid particles. Flavor containing particles can be incorporated within dry beverage or gelatin mixes and perfume containing particles can be added to detergents.
