Abstract

METHOD FOR DETECTING BOAR ODOR The present invention relates to the use of a probe, in particular chosen from rhodamine or one of its derivatives, for the detection of at least one molecule responsible for boar odor, such as indole or skatole, said probe being chosen, for example, from the group consisting of rhodamine 6G, eosin Y, rhodamine B, and rhodamine 101.

Claims

Demands

1. Use of a probe for the detection of at least one molecule responsible for boar odor, said probe being selected from sensitizers having a ground state reduction potential, Eredi / 2(S / S-), strictly less than the reduction potential of the molecule responsible for boar odor, and having either a singlet excited state reduction potential, ES1 red, strictly greater than the reduction potential of the molecule responsible for boar odor, or a triplet excited state reduction potential, ET1red, strictly greater than the reduction potential of the molecule responsible for boar odor.

2. Use according to claim 1, wherein the singlet excited state reduction potential, Eslred, or the triplet excited state reduction potential, ET'red, of the sensitizer is from 0.7 V to 2 V, preferably from 0.7 V to 1.7 V, and even more preferably from 0.7 V to 1.2 V.

3. Use according to claim 1 or 2, wherein the probe is selected from rhodamines, xanthenes and tetrazines.

4. Use according to claim 3, wherein the probe is selected from the group consisting of rhodamine 6G, eosin Y, rhodamine B and rhodamine 101.

5. Use according to claim 3 or 4, wherein the probe is rhodamine 6G or eosin Y.

6. Use according to any one of claims 1 to 5, wherein the molecule responsible for the boar odor corresponds to the following formula (II): R1 H in which R1 is H or methyl.

7. Use according to any one of claims 1 to 6, wherein the molecule responsible for the boar odor is skatole.

8. A method for detecting at least one molecule responsible for boar odor in a pig sample, said method comprising the following steps: a) bringing a pig sample into contact with a probe as defined in any one of claims 1 to 5, and b) measuring the fluorescence intensity of the probe after step a), c) comparing the value obtained in step b) with the fluorescence intensity of the probe alone, and d) deducing whether the pig sample contains at least one molecule responsible for boar odor.

9. A method for detecting at least one molecule responsible for boar odor according to claim 8, wherein the pig sample is a sample of meat, carcass or fatty tissue.

10. A method according to claim 8 or 9, wherein the probe is selected from the group consisting of rhodamine 6G, eosin Y, rhodamine B and rhodamine 101.

11. A method according to any one of claims 8 to 10, wherein the fluorescence intensity is measured by fluorescence spectrometry.

12. A method for sorting whole male pig carcasses, comprising implementing a method according to any one of claims 8 to 11.

13. Device for detecting at least one molecule responsible for boar odor comprising at least one probe as defined in any one of claims 1 to 5, preferably selected from the group consisting of rhodamine 6G, eosin Y, rhodamine B and rhodamine 101.
