Embodiment 1
[0033](1) Pre-treatment: After removing impurities from Eucommia ulmoides, the dried eucommia samara is removed with a sheller; the seed kernels are properly mechanically crushed and placed in a dry and cool place for extraction and separation of Eucommia ulmoides fruit seed oil.
[0034] (2) Separation of eucommia seed oil and eucommia gum:
[0035] A. Eucommia gum separation
[0036] a, seed shell steam explosion treatment: the seed shell that step (1) obtains is placed in the water of 30 ℃ and soaks 1h, then the material after soaking is put into steam explosion device and carries out steam explosion, and the pressure of steam explosion is 0.5MPa, control The steam explosion temperature of the steam explosion device is 180°C, the maintenance pressure is 1min, and the material temperature after steam explosion is room temperature;
[0037] b, enzymolysis: the filter residue in step a is added distilled water according to the ratio of material to liquid ratio 1:10, adjusts ...
