Preparation of an emulsion based on aromatic vegetable material involves placing the vegetable material in a heated chamber in the absence of solvents, irradiating with microwaves while applying reduced pressure, cooling the vapor containing the essential oils to give a 2-phase solution and stirring to form an emulsion. Preparation of an emulsion based on aromatic vegetable material comprises: (a) placing the vegetable material in a heated chamber in the absence of solvents; (b) irradiating with microwaves while applying reduced pressure, such that the cellular structures are broken up and the aromatic oils are distilled off by water vapor from the vegetable material; (c) cooling the vapor containing the essential oils to give a 2-phase solution; and (d) stirring to form an emulsion. An Independent claim is also included for the emulsion obtained by above method. |
