Eucommia ulmoides key fruit hull treating method beneficial to extraction of gutta-percha

Abstract

The invention discloses a eucommia ulmoides key fruit hull treating method beneficial to extraction of gutta-percha. The eucommia ulmoides key fruit hull treating method comprises the steps: (1), preparing an irpex lacteus seed solution; (2), inoculating and culturing a eucommia ulmoides key fruit hull; and (3), treating after fermenting. The dry weight of the treated eucommia ulmoides key fruit hull is reduced by 35-42 percent due to effective degradation of the irpex lacteus, the gutta-percha in the fruit hull can reach 50-60 percent, the efficiency and rate of extracting the gutta-percha by using organic solvents such as petroleum ether are greatly increased, and the glue quality is remarkably improved. The treatment effect of the eucommia ulmoides key fruit hull treating method is superior to an existing enzymic method and a distiller's yeast and yeast fermentation method; the eucommia ulmoides key fruit hull treating method has no damage to environment; the environment benefit of the eucommia ulmoides key fruit hull treating method is superior to that of an alkali treatment method; the eucommia ulmoides key fruit hull treating method is stronger in actual application value.

Description

technical field

[0001] The invention relates to a method for processing eucommia samara shells, in particular to a method for enhancing the extraction of eucommia gum by treating the eucommia samurai shells with the eucommia alba. Background technique

[0002] Eucommia gum is a new functional material. Eucommia gum and natural rubber produced in Hevea trilobata are isomers. Eucommia gum is trans-polyisoprene, and natural rubber is cis-polyisoprene. After vulcanization, Eucommia gum can be in rubber state or in different plastic states. There are many Eucommia gum products on the market, and its market application prospect is very broad.

[0003] Eucommia gum mainly exists in the bark, leaves and fruits of Eucommia ulmoides, among which Eucommia samara has a gum content as high as 15%-30% and can be harvested every year, so it has become an ideal raw material for extracting Eucommia gum. In order to obtain eucommia gum with high purity, it is generally extracted with non-pol...
