Embodiment 1

[0032] A method for enzymatically extracting eucommia gum, comprising the steps of:

[0033] 1), first use the hay cutter to cut the eucommia bark as raw material into an area no larger than 25cm 2 Then put it into clear water at room temperature and soak it for 12.5 hours, then remove it, put it into a blasting machine, and blast it to obtain Eucommia bark intermediate I for later use;

[0034] In this step, the blasting temperature is controlled below 50°C, the blasting pressure is controlled at 1.4 MPa, and the blasting time is controlled at 0.4S;

[0035] 2), put the Eucommia bark intermediate I obtained in step 1) into the aqueous solution of protease and repeatedly stirred and washed for 7 hours, then repeatedly stirred and washed with water for 1.5 hours to obtain the Eucommia bark intermediate II:

[0036] When washing in this step, the various components are configured according to the following parts by weight: 90 parts of Eucommia bark intermediate I, 140 parts of ...

Embodiment 2

[0043] A method for enzymatically extracting eucommia gum, comprising the steps of:

[0044] 1), first use the hay cutter to cut the eucommia bark as raw material into an area no larger than 25cm 2 Then put it into clear water at room temperature and soak for 13 hours, then remove it, put it into a blasting machine, and blast it to obtain Eucommia bark intermediate I for later use;

[0045] In this step, the blasting temperature is controlled below 50°C, the blasting pressure is controlled at 1.5 MPa, and the blasting time is controlled at 0.3S;

[0046] 2), put the Eucommia bark intermediate I obtained in step 1) into the aqueous solution of protease and repeatedly stir and wash for 8 hours, then repeatedly stir and wash with clear water for 2 hours to obtain the Eucommia bark intermediate II:

[0047] When washing in this step, various components are configured according to the following parts by weight: 100 parts of Eucommia bark intermediate I, 150 parts of hot water and ...

Embodiment 3

[0054] A method for enzymatically extracting eucommia gum, comprising the steps of:

[0055] 1), first use the hay cutter to cut the eucommia bark as raw material into an area no larger than 25cm 2 Then put it into clear water at room temperature and soak it for 14 hours, then take it out, put it into the blasting machine and blast it to get Eucommia bark intermediate Ⅰ for later use;

[0056] In this step, the blasting temperature is controlled below 50°C, the blasting pressure is controlled at 1.8 MPa, and the blasting time is controlled at 0.5S;

[0057] 2) Put the eucommia bark intermediate I obtained in step 1) into the aqueous solution of protease and repeatedly stir and wash for 9 hours, then repeatedly stir and wash with water for 2.5 hours to obtain the eucommia bark intermediate II:

[0058] When washing in this step, the various components are configured according to the following parts by weight: 110 parts of Eucommia bark intermediate I, 160 parts of hot water an...

Abstract

The invention discloses a method for extracting gutta-percha through enzymolysis. The method comprises the following steps: eucommia barks using as raw materials are burst and crushed, protease is used for decomposing protein components in the eucommia barks, pectinase is used for decomposing cell walls and intercellular layers in the eucommia barks, cellulase is used for improving the decomposition of cellulose and hemicellulose so as to decompose non-gutta-percha substances in the eucommia barks into components which can be completely separated from gutta-percha, and target substances are separated from waste components by adopting a method of rotating a separation tube in an enzymolysis device in a water tank, wherein rectangular stirring blades are arranged on the inner wall of the separation tube, and form inclination angles of 10 to 15 degrees with a support shaft, so that the separation completeness of the target substances and the waste components is ensured. The method is clean, safe, environment-friendly, low in cost, high in efficiency and suitable for industrial production, and the purity of the extracted gutta-percha is high, and can reach over 92 percent.

Description

technical field [0001] The invention relates to a method for extracting natural gum, in particular to a method for enzymatically extracting Eucommia gum. Background technique [0002] Eucommia ulmoides is a precious tree species unique to my country. Eucommia ulmoides gum contained in eucommia ulmoides, as a natural rubber, has the advantages of high insulation and corrosion resistance. It is a high-quality material for manufacturing submarine cables. Medicine container and excellent raw material for dental fillings. Eucommia gum can also be used to make medical splints, automobile tires, shape memory materials, temperature detection materials, modified plastics and other rubber products, so it has broad application prospects. [0003] There are two types of existing methods for extracting Eucommia gum from Eucommia ulmoides, one of which is: the raw material bark of Eucommia ulmoides is fully fermented and then boiled with a strong alkali aqueous solution, and then separate...
