Ginger CO2 extract, produced via supercritical carbon dioxide extraction at ~31°C from Zingiber officinale rhizomes, retains substantially higher concentrations of 6-gingerol and related pungent phenylalkanol compounds than conventional steam-distilled oil, because the low-temperature process minimises heat-driven conversion of gingerols to shogaols — a transformation that occurs readily above 60°C during steam distillation.^[1] The result is an aroma dramatically closer to freshly cut ginger root: richer, more complex, more resinous, and heavier than the lighter, zingiberene-dominant character of steam-distilled oil. Transdermal and pharmacological studies confirm that 6-gingerol retained in CO2 extracts is the primary bioactive underpinning anti-nausea, anti-inflammatory, and antioxidant applications, making the CO2 form preferred where higher gingerol bioavailability is therapeutically relevant.^[2]
