Canola oil is an excellent vehicle for eliminating pesticide residues in aqueous ginseng extract

We previously reported that two-phase partition chromatography between ginseng water extract and soybean oil efficiently eliminated pesticide residues. However, an undesirable odor and an unpalatable taste unique to soybean oil were two major disadvantages of the method. This study was carried out to find an alternative vegetable oil that is cost effective, labor effective and efficient without leaving an undesirable taste and smell.
