Abstract: Method of deodorising a mercaptoacid of formula HS-A-COOH in which A is: -(CH2)n-; in which most of the malodorous decomposition compounds of the mercaptoacid are extracted using a supercritical fluid consisting of a compound of which the critical temperature is between 0 and 135@C and the critical pressure is between 10 and 10 pascals, the extraction being carried out in the presence of at least one polar solvent of the mercaptoacid. Deodorised product obtained.

Abstract: Method for deodorising a mercaptoacid of formula HS-A-COOH, in which formula A represents: -(CH2)n-; according to which most of the malodorous decomposition compounds of the mercaptoacid are extracted using carbon dioxide (CO2) in the gaseous, liquid or solid state. Deodorised product obtained.
