| description | The invention provides a method for enzyme-assisted extraction of turmeric essential oil. The method comprises the following steps: mechanically crushing turmeric, and sieving to obtain turmeric powder; weighing turmeric powder, adding an enzyme, adding a buffer solution, uniformly mixing, and carrying out enzymolysis in a constant-temperature shaking table to obtain an enzymatic hydrolysate; filling the enzymatic hydrolysate into a round-bottom flask, adding water and glass beads, shaking and mixing, connecting a volatile oil detector and a reflux condensing tube, putting into an electric jacket, slowly heating until boiling, cooling tap water, keeping slight boiling for 1 hour, and stopping heating; opening a piston at the lower end of the measuring tube to slowly discharge water, then opening the piston to enable an oil layer to descend until the upper end of the oil layer is just flush with the scale 0, collecting essential oil, and reading the volume of the turmeric essential oil; and calculating the oil |
