Abstract
Official abstract text for this publication.
An odorant mixture is disclosed. The odorant mixture comprises N odorant components wherein N equals at least 20. Each odorant component is characterized by a multidimensional vector of attributes. A z score of an average of characteristic distances between vectors corresponding to odorant components in the mixture and vectors corresponding to odorant components in a group of M odorant components but not in the mixture is less than 2.
First claim
Opening claim text (preview).
What is claimed is: 1. An odorant mixture, comprising N odorant components wherein N equals at least 20, each odorant component being characterized by a multidimensional vector of attributes, such that the mixture is characterized by N respective multidimensional vectors, wherein a z score of an average of characteristic distances between vectors corresponding to odorant components in the mixture and vectors corresponding to odorant components in a group of M odorant components but not in the mixture is less than 2, and wherein said M equals at least 100. 2. The odorant mixture according to claim 1 , wherein at least a portion of said N odorant components is selected from said group of M odorant components. 3. The odorant mixture according to claim 1 , wherein M is at least equal to N. 4. The odorant mixture according to claim 1 , wherein said N odorant components have similar odor intensity. 5. The odorant mixture according to claim 1 , wherein each characteristic distance is defined as a minimum distance between a vector corresponding to odorant components in the mixture and a vector corresponding to an odorant component in said group of M odorant components but not in the mixture. 6. The odorant mixture according to claim 1 , wherein each of said multidimensional vectors has at least 50 dimensions. 7. The odorant mixture according to claim 1 , wherein N equals at least 30. 8. The odorant mixture according to claim 1 , wherein said group of M odorant components is selected from the odorant components listed in Table A.1 or Table A.2 of Annex 1. 9. The odorant mixture according to claim 1 , wherein said group of M odorant components is the group listed in Table A.1 of Annex 1. 10. The odorant mixture according to claim 1 , wherein said group of M odorant components is the group listed in Table A.2 of Annex 1. 11. The odorant mixture according to claim 1 , wherein each of said N odorant component is in a gaseous state. 12. The odorant mixture according to claim 1 , wherein said z-score is with respect to a synthetic database which comprises a plurality of entries, each corresponding to a database odorant mixture defined as being producible from a plurality of odorant components selected from said group of M odorant components. 13. A method of at least partially masking a target odor in an environment, comprising spreading an odorant mixture according to claim 1 in the environment, thereby providing a combined mixture having said odorant mixture and odorant components of the target odor. 14. The method according to claim 13 , wherein a z score of an average of characteristic distances between vectors corresponding to odorant components in said combined mixture and vectors corresponding to odorant components in said group of M odorant components but not in said combined mixture is less than 1.
