Description
Sabrinna Wulandari and co-authors tested a greener way to recover value from red ginseng marc, the residue left after hot water extraction. Their 2026 study used dimethyl ether as a solvent, tuning temperature, pressure, and extraction time with response surface methodology. Conventional methods demand harsh conditions and extra solvent removal, raising costs, while the marc still holds useful lipids and bioactives.
At the best setting, 333 K, 7 MPa, and 80 minutes, yield reached 3.37%, with total ginsenoside content of 4.22 mg per gram of dry marc and strong antioxidant activity. The dimethyl ether oil beat ethanol and hexane extracts on antioxidant activity and fatty acid content, and it could be drawn directly from wet marc without prior drying. The authors highlight dimethyl ether as an energy-efficient solvent for food and cosmetic uses of ginseng oil.
