In order to investigate industrialized results of extracting flaxseed by two-liquid-phase technology, the feasibiltity of multistage adverse current extraction technology in oils and cyanogenic glycosides extracted simultaneously from flaxseed by two-liquid-phase system of ethanol-hexane-water was discussed using model experiment. The optimum extracting conditions are ethanol 85% (m/m), material : ethanol = 1:2 (m/V), material : hexane = 1:5 (m/V), time 30 min, temperature 55℃, NaOH concentration 0.05% (m/V) in ethanol. Serial simulation of four stages adverse current extraction decreased concentration of oils and cyanogenic glycosides in flaxseed flakes to less than 1% and 0.7 mg/kg, respectively. Flow diagram for multistage adverse current extraction is fit for process of flaxseed oils and cyanogenic glycosides extracted by two-liquid-phase system.
