| titleOfInvention | Extraction procedure of an odorant extract with an alternative solvent to conventional solvents |
| abstract | Process for extracting an extract of volatile odorant compounds, each having a molecular weight of less than 350 g/mol, from an organic raw material containing volatile odorant compounds, comprising the steps according to which: a) brings into contact in at least one bath, at a temperature between 10 and 70 °C, said organic raw material with dimethyl carbonate used as a solvent in said bath to load said dimethyl carbonate solvent with volatile odorant compounds each having a molecular weight of less than 350 g/mol of said organic material and obtaining a liquid organic phase; b) the liquid organic phase of said bath is collected, comprising dimethyl carbonate loaded with volatile odorant compounds each having a molecular weight of less than 350 g/mol; c) in the event that the collected liquid organic phase comprises an aqueous phase immiscible with the dimethyl carbonate resulting from the organic matter, the liquid organic phase is decanted to separate the dimethyl carbonate loaded with volatile odorant compounds from said immiscible aqueous phase and the aqueous phase is removed; d) dimethyl carbonate is partially removed by evaporation and a preconcentrated extract of volatile odorant compounds is recovered; (e) if, after partial removal of dimethyl carbonate by evaporation, the preconcentrated extract of volatile odorant compounds comprises water, the preconcentrated extract is decanted to remove the water; f) an alcohol is added to the dimethyl carbonate to form an azeotrope with the dimethyl carbonate by azeotropic dragging; and g) the preconcentrated extract of volatile odorant compounds is concentrated by evaporation of the azeotropic mixture to obtain the extract of volatile odorant compounds. |
