Problems solved by technology

[0003] CN104292352A The existing disadvantage needs to be extracted by alkali, which may seriously pollute the environment
Existing methods cannot completely open the cell wall of plant tissue, and the content of eucommia gum in the extracted crude gum is low, and the utilization value is poor
In addition, the existing technology is often a single extraction of eucommia gum or a single acquisition of eucommia powder, and the lye extracted by alkali can significantly degrade the medicinal components, resulting in a greatly reduced health care effect of the powder, which cannot Realize the comprehensive development and utilization of Eucommia leaves or Eucommia bark

Embodiment 1

[0047] (1) Use non-ground Eucommia leaves as raw materials to remove sediment and sundries;

[0048] (2) Na 2 HPO 41. Citric acid is made into a buffer solution I with a pH of about 3.0, and the mass concentration of the buffer solution I is about 1.3%;

[0049] Take SUKAPro AC enzyme accounting for 4% of the weight of raw material Eucommia leaves and dissolve it in buffer solution I to obtain mixed solution enzyme solution I (the enzyme activity of SUKAPro AC enzyme is 90u / mL;); the weight ratio of raw material Eucommia leaves to enzyme solution I For: 1:3;

[0050] Add Eucommia ulmoides leaves and enzyme solution I into the enzymolysis reaction rotary tank and perform enzymolysis at 50°C for 10 hours to obtain enzymolysis solution I;

[0051] Separating the enzymolysis solution I, the solid residue I containing glue is still kept in the enzymolysis reaction rotary tank for standby; the discharged enzymolysis solution I enters the process of preparing Eucommia fine powder;...

Embodiment 2

[0081] (1) take Eucommia bark as raw material, remove the rough bark on the surface of the bark, and keep the inner layer of clean bast containing glue;

[0082] (2) Na 2 HPO 4 1. Citric acid is made into a buffer solution I with a pH of about 3.0, and the mass concentration of the buffer solution I is about 1.3%;

[0083] Take 3.5% SUKAPro AC enzyme (the enzyme activity of SUKAPro AC enzyme is 500u / mL;) that accounts for 3.5% of the weight of the bark of raw material Eucommia and dissolve it in buffer solution I to obtain mixed solution enzyme liquid I; the mixture of raw material Eucommia bark and enzyme liquid I The weight ratio is: 1:3;

[0084] The bark of Eucommia ulmoides and enzyme liquid I were added to the enzymatic hydrolysis reaction rotary tank and enzymolyzed at 50°C for 10 hours to obtain enzymatic hydrolysis liquid I;

[0085] Separating the enzymolysis solution I, the solid residue I containing glue is still kept in the enzymolysis reaction rotary tank for ...

Embodiment 3

[0106] Take the precipitate obtained after the alcohol precipitation in step (8) in Example 1, dry to about 5% of its moisture content, take out 5 different batches of samples (the preparation method is exactly the same, only the batches are different), Denoted as A, B, C, D, E, through microbial detection, detect their inhibitory action to escherichia coli, Staphylococcus, Salmonella, the result is as follows: (inhibition rate %)

[0107]

[0108] For the detection method, please refer to the "Porous Plate-MTT Colorimetric Method for Measuring the Inhibitory Activity of Plant Antibacterial Components on Bacteria" invented by Tang Jing, Tan Manliang and others in "China Science and Technology Papers Online";

[0109] As can be seen from the data in the above table, when the alcohol precipitation obtained in the present invention is used for feed, it has a strong inhibitory effect on Staphylococcus, and has a certain inhibitory effect on Salmonella. Therefore, after it is app...

Abstract

The invention belongs to the technical field of folium eucommiae processing, and particularly relates to a comprehensive utilization method for folium eucommiae and cortex eucommiae. The method is a green biochemical method for carrying out enzymolysis on the folium eucommiae and cortex eucommiae by biological enzyme. The obtained enzymatic hydrolysate is used for preparing cortex eucommiae fine powder, fertilizer and feed, and obtained solid residues are subjected to further enzymolysis to prepare cortex eucommiae coarse glue. According to the comprehensive utilization method, the cortex eucommiae coarse glue, the cortex eucommiae fine powder and the obtained feed and fertilizer can be realized in the same technical route, and folium eucommiae and cortex eucommiae raw materials are subjected to full recycling and appreciation comprehensive utilization.

Description

technical field [0001] The invention belongs to the technical field of eucommia processing, and in particular relates to a method for comprehensively utilizing eucommia leaves or eucommia bark. Background technique [0002] CN104292352A discloses a co-production extraction and separation method of eucommia fine powder, eucommia polysaccharide and eucommia gum, including a pretreatment step, an extraction step, a membrane filtration step and a finished product preparation step, and the finished product preparation step includes preparation of eucommia fine powder, eucommia Preparation of water-extracted polysaccharides, eucommia base-extracted polysaccharides, and eucommia gum; the inventive eucommia fine powder, eucommia polysaccharides, and eucommia gum co-production extraction and separation methods effectively realize the comprehensive development and utilization of eucommia biomass resources and reduce the cost of eucommia in the development process. The cost of eucommia...
