In order to study the effective extraction of ginger oleoresin,ginger protease and curcumin simultaneous extraction,ethanol solvent combined with rotary evaporation was studied.The ratio of ginger and ethanol liquid ratio was 1∶ 3 g∶ mL),extraction buffer pH 6.5,ice bath time 7h;for the ginger oleoresin and curcumin rotary evaporation,the optimum temperature was 60℃,the rotating speed was 16 r/min.Under the above optimized conditions,gingerol in ginger,curcumin extraction rate was 0.314 3% and 0.388 9%;ginger protease ratio was 1.376%,specific enzymatic activity reached to 4 465 U/mg.This process can simultaneously extract gingerol,curcumin and ginger protease three effective components,reduce the consumption of raw materials,the production cost,and therefore more suitable for industrial production.
