A method of evaluating inhibitory effect on damp-dry malodor, containing the steps of: bringing microorganisms which produce damp-dry malodor-causing substances and a test substance into contact with each other in the presence of a sebaceous dirt component; detecting expression of at least one kind of gene selected from a fatty acid desaturase gene and a &#x3b2; oxidation-related enzyme gene derived from the microorganisms; and thereby evaluating a damp-dry malodor inhibitory function of the test substance based on a change in expression amount of the at least one kind of gene.

Method of evaluating inhibitory effect on damp-dry malodor

A method of screening a damp-dry malodor inhibitor, containing the steps of: bringing microorganisms having a 4-methyl-3-hexenoic acid production capacity into contact with a test substance in the presence of a sebaceous dirt component, detecting the production of a damp-dry malodor-causing substance by the microorganisms, and thereby selecting a test substance having a damp-dry malodor inhibitory function; and a method of evaluating a damp-dry malodor inhibitor, containing the steps of: bringing microorganisms having a 4-methyl-3-hexenoic acid production capacity into contact with a test substance in the presence of a sebaceous dirt component, detecting the production of a damp-dry malodor-causing substance by the microorganisms, and thereby evaluating the damp-dry malodor inhibitory function of the test substance.
