摘要:
Methods for extracting an extract of volatile odorous compounds from an organic raw material containing odorous compounds is disclosed. The method includes contacting an organic raw material with dimethyl carbonate, as a solvent, in at least one bath at a temperature of 10° C. to 70° C. A liquid organic phase is obtained that includes the dimethyl carbonate charged with volatile odorous compounds and is collected. If the liquid organic phase comprises an immiscible aqueous phase, decanting occurs to separate the dimethyl carbonate charged with odorous compounds therefrom thereby eliminating the aqueous phase. Next, partially eliminating by evaporation forms a pre-concentrated extract of volatile odorous compounds, which is recovered and if water is present, decanting occurs to eliminate the water. Additionally, concentrating the pre-concentrated extract of volatile odorous compounds by evaporation is performed to obtain the extract of volatile odorous compounds.
