Goji berry

Perfume artisans obtain goji berry absolute through solvent extraction of dried fruit. First, growers harvest fully ripe berries from Lycium barbarum shrubs in high‑altitude valleys. The fruit is freeze‑dried to preserve volatile compounds, then ground into a fine powder. Ethanol or hexane solvents percolate the powder, dissolving aromatic esters, aldehydes, and trace terpenes. The mixture rests for several hours, after which the solvent is filtered and evaporated under reduced pressure, leaving a thick, amber‑colored absolute. Some houses employ supercritical CO₂ extraction to reduce solvent residues and capture a broader spectrum of volatiles. The resulting material contains 2‑3 % aromatic constituents by weight, which perfumers dilute before blending. Throughout the process, temperature control and gentle agitation preserve the fruit’s delicate freshness, while modern recovery systems recycle solvents for sustainability.
