Abstract
Abstract A process for the production of an aromatic spice extract, which comprises (A) GRINDING A SPICE AND COLLECTING AN AROMATIC FRACTION A, consisting of the gases given off during grinding, (B) TREATING THE SPICE WITH AN APOLAR ORGANIC SOLVENT SO AS TO OBTAIN AN AROMATIC FRACTION B contained in this apolar solvent, and (C) TREATING THE SPICE WITH AT LEAST ONE POLAR SOLVENT SO AS TO OBTAIN AN AROMATIC FRACTION C contained in this polar solvent, THE COMBINATION OF THE AROMATIC FRACTIONS A, B and C constituting the aromatic spice extract.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
116 words
A process for the production of an aromatic spice extract, which comprises: (a) grinding a spice at low temperature, increasing the temperature of the ground spice to liberate an aromatic fraction A consisting of grinding gases, entraining the grinding gases by a stream of inert gas and collecting the aromatic fraction A by condensation, (b) treating the ground spice with an apolar organic solvent so as to obtain an aromatic fraction B contained in this apolar solvent, (c) treating the ground spice with at least one polar solvent so as to obtain an aromatic fraction C contained in this polar solvent, and (d) combining aromatic fractions A, B and C to produce the aromatic spice extract.
Claim 2
Dependent Claim
116 words
A process for the production of an aromatic spice extract, which comprises: (a) grinding a spice at low temperature, increasing the temperature of the ground spice to liberate an aromatic fraction A consisting of grinding gases, entraining the grinding gases by a stream of inert gas and collecting the aromatic fraction A by condensation, (b) treating the ground spice with an apolar organic solvent so as to obtain an aromatic fraction B contained in this apolar solvent, (c) treating the ground spice with at least one polar solvent so as to obtain an aromatic fraction C contained in this polar solvent, and (d) combining aromatic fractions A, B and C to produce the aromatic spice extract.
