NOVELTY - Enzymatic extraction of gutta percha comprises (i) cutting Eucommia ulmoides bark using a guillotine to 25 cm2 pieces, soaking the cut pieces in water, blasting to obtain intermediate I; (ii) washing the Eucommia ulmoides bark intermediate I with protease aqueous solution to obtain Eucommia ulmoides bark intermediate II; (iii) washing the intermediate II with pectinase aqueous solution to obtain Eucommia ulmoides bark intermediate III; and (iv) washing the intermediate III with cellulase aqueous solution to obtain white filamentous gutta percha.    USE - The method is useful for Enzymatic extraction of gutta percha (claimed).    ADVANTAGE - The method is hygienic, safe, environmentally-friendly and economical, has high efficiency. The gutta percha has high purity of more than 92%, and is suitable for industrial production.    DETAILED DESCRIPTION - Enzymatic extraction of gutta percha comprises (i) cutting Eucommia ulmoides bark using a guillotine to 25 cm2 pieces, soaking the cut pieces in water at room temperature, remove after 12 hours, blasting the Eucommia ulmoides bark in a blasting machine at less than 50 degrees C, under 1.4-1.8 MPa for 0.5 seconds to obtain intermediate I; (ii) washing the Eucommia ulmoides bark intermediate I with protease aqueous solution repeatedly, stirring for 7-9 hours, and washing with clean water for 1.5-2.5 hours to obtain Eucommia ulmoides bark intermediate II, where the washing process includes using 90-110 pts. Eucommia ulmoides bark intermediate I, 10-15 pts. hot water and 140-160 pts. protease, and controlling the hot water temperature to 40-50 degrees C; (iii) repeatedly washing the Eucommia ulmoides bark intermediate II with pectinase aqueous solution and stirring for 7-9 hours, then washing with clean water and stirring for 1.5-2.5 hours to obtain Eucommia ulmoides bark intermediate III, where the washing process includes using 90-110 pts. Eucommia ulmoides bark intermediate II, 140-160 pts. hot water and 10-15 pts. pectinase, and controlling the hot water temperature to 40-50 degrees C; and (iv) repeatedly washing the Eucommia ulmoides bark intermediate III with cellulase aqueous solution and stirring for 7-9 hours, then washing with clean water and stirring for 1.5-2.5 hours to obtain white filamentous gutta percha, where the washing process includes using 90-110 pts. Eucommia ulmoides bark intermediate III, 140-160 pts. hot water and 10-15 pts. cellulase, and controlling the hot water temperature to 40-50 degrees C. The step (ii), (iii) and (iv) was carried out in an enzymatic reactor, which is provided a sink and a separation tube; the separation tube is cylindrical, and is horizontally disposed on the upper edge of the tank via central support shaft; the tank stores the enzyme aqueous solution, and a portion of the separation tube is immersed in the enzyme aqueous solution, and other portion of the tube is placed inside the Eucommia ulmoides bark intermediate; the side wall of the separator tube is provided with a separate hole having diameter of 0.8-1.2 mm, and the inner wall of the separator tube is also provided with a longitudinal rectangular stirring blade. The longitudinal stirring blades and the central support shaft having a tilt angle of 10-15 degrees , and the stirring blades width direction is towards the central support shaft. The enzyme has a non-adhesive material, which is discharged from the separator in the separator tube bore tank, and then discharged in the waste water tank.
