METHOD FOR DETECTING BOAR ODOR

Abstract

METHOD FOR DETECTING BOAR ODOR The present invention relates to the use of a probe chosen in particular 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

Claims

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

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 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, in which the molecule responsible for boar taint 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 boar taint is skatole.

8. Method for detecting at least one molecule responsible for boar taint in a pork sample, said method comprising the following steps: a) bringing a pork 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 therefrom whether the pork sample contains at least one molecule responsible for boar taint.

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

10. The method of 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 of sorting whole male pig carcasses, comprising carrying out a method according to any one of claims 8 to 11.

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