-"Since decades mimosa (Acacia dealbata) absolute oil has been used in the flavor and perfume industry. Today, it finds an application in over 80 perfumes, and its worldwide industrial production is estimated five tons per year. Here we report on the chemical composition of French mimosa absolute oilStraight-chain analogues from C6 to C26 with different functional groups (hydrocarbons, esters, aldehydes, diethyl acetals, alcohols, and ketones) were identified in the volatile fraction. Most of them are long-chain molecules: (Z)-heptadec-8-eneheptadecanenonadecane, and palmitic acid are the most abundant, and constituents such as 2-phenethyl alcohol, methyl anisate, and ethyl palmitate are present in smaller amountsThe heavier constituents were mainly triterpenoids such as lupenone and lupeolwhich were identified as two of the main components. (Z)-Heptadec-8-enelupenone, and lupeol were quantified by GC−MS in SIM mode using external standards and represents 6%, 20%, and 7.8% (w/w) of the absolute oilMoreoverodorant compounds were extracted by SPME and analyzed by GC-sniffing leading to the perception of 57 odorant zones, of which 37 compounds were identified by their odorant descriptionmass spectrumretention index, and injection of the reference compound." \\+"Since decades mimosa (Acacia dealbata) absolute oil has been used in the flavor and perfume industry.

 +As the distillate lacks the typical mimosa note, it was not suitable for GC-sniffing analyses. However, the absolute could not be directly used because of the presence of nonvolatile (and odorless) compoundsThus, HS-SPME with a CAR/PDMS 75 μm fiber (extraction of highly volatile compoundswas chosen as sampling method. Fifty-seven odorant zones were detected by the two sniffers during HS-SPME-GC-sniffing. Thirty-seven compounds could be identified with certainty (LRIMSodor comparison, and injection of the reference compound)... Eighteen odorant zones were described as fruity and could be attributed to esters such as ethyl propanoate, butanoate, pentanoate, and hexanoate. Phenylacetaldehyde, 2-phenethyl alcohol, benzyl acetate, and (Z)-jasmone were the main “floral” compounds responsible for four of the thirteen floral zonesFresh and green notes were perceived, often due to aldehydes (hexanal, heptanal, nonanal, and (E,Z)-nona-2,6-dienal). Three out of five mushroom notes were identified as (Z)-pent-2-en-1-ol(E)-oct-2-en-1-ol, and oct-1-en-3-olVanillinmethyl and ethyl anisates were identified, contributing to sugar and anise-like odors. Four zones with similar notes could not be identified. The predominance of fruityfloralfreshgreen, mushroom, sugar and anise-like odorant notes is in agreement with the descriptors used for mimosa absolute oil." \\
