PCT No. PCT/EP93/02350 Sec. 371 Date Mar. 7, 1995 Sec. 102(e) Date Mar. 7, 1995 PCT Filed Aug. 31, 1993 PCT Pub. No. WO94/06018 PCT Pub. Date Mar. 17, 1994A process and appropriate device are disclosed for determining the androstenone content of adipose tissues in clearly shorter times. The disclosed process has the following steps: (a) liquefying an adipose tissue sample by heating up to a predetermined temperature in the 45 DEG to 60 DEG C. range; (b) mixing a defined amount of the liquid fat with a water-soluble solvent for androstenone at the temperature of the liquid; (c) cooling the fat/solvent mixture down to a predetermined temperature, at which a substantial proportion of the fat dissolved in the solvent is separated from the solution whereas the major part of the androstenone dissolved in the solvent phase remains dissolved in the solvent; (d) sampling of a defined amount of the androstenone-containing solvent phase and diluting it in a predetermined ratio with an aqueous buffer solution admissible for the used detection process; (e) determining the androstenone content of the solvent/buffer solution phase by means of known per se competitive immunological detection reactions.
