The method extracting Fructus Cannabis oligopeptide.
Background technology
Fructus Cannabis is the kernel of moraceae plants Fructus Cannabis (Cannabis sativa L.), has and moisturizes laxation, diuretic
Effect treating stranguria, that invigorate blood circulation, is the laxative drug that the most also medicine is also eaten.Modern study shows, Fructus Cannabis has preferably
Blood pressure lowering, paroxysmal pain, antiinflammatory, antithrombotic effect, be eaten for a long time, paralysis scorching to chronic forms,
Ulcer and gynaecopathia have good auxiliary curative effect.Fructus Cannabis grouts are to utilize Fructus Cannabis to extract Fructus Cannabis
Residue after oil, wherein protein content is up to 56%, containing the various necessary aminoacid of needed by human body, special
Not rich in arginine, lysine and glutamic acid, it is the most excellent a kind of vegetable protein new resources, Fructus Cannabis
Grouts remain Fructus Cannabis major part effect.
Containing the most oxidized aldehydes matter in Fructus Cannabis, the Fructus Cannabis cake after Fructus Cannabis processing can be remained in
In the dregs of rice, pink colour oxidation product can be produced after oxidation in atmosphere, have impact on Fructus Cannabis grouts institute converted products
Color and luster.It addition, possibly together with a part of monosaccharide in addition to containing protein in Fructus Cannabis grouts so that Urtica cannabina L.
The separating technology of core albumen is complex.
Prior art extracts egg albumen powder, and complicated process of preparation only with extraction from Fructus Cannabis,
Product purity is relatively low.And the method preparing Fructus Cannabis oligopeptide for raw material with Fructus Cannabis grouts have not been reported.
Summary of the invention
It is an object of the invention to develop a kind of Fructus Cannabis grouts to deoil through squeezing as raw material, preparation height
The method of quality Fructus Cannabis oligopeptide, it is provided that the utilization rate of Fructus Cannabis.
For reaching above-mentioned purpose, the invention provides and a kind of from Fructus Cannabis grouts, extract Fructus Cannabis oligopeptide
Method, concretely comprises the following steps:
S1, the collection fat content Fructus Cannabis grouts less than 1%, by Fructus Cannabis grouts: the mass ratio of water=1:20
In described Fructus Cannabis grouts, add water, adjust pH to 9.0 by the NaOH solution of 2.5mol/L, add described
The sodium metabisulfite of Fructus Cannabis grouts quality 1% amount, carries out solid-liquid for the first time after 70 DEG C of heated and stirred 30min
Separate, collect liquid phase；In described liquid phase, add the HCl solution of 2.5mol/L, regulate pH to 3.8～4.3
After, stand 2h and carry out second time solid-liquid separation, collect precipitation, be Fructus Cannabis separation albumen；
In Fructus Cannabis grouts lysate, add the sodium metabisulfite of 1%, can effectively prevent Fructus Cannabis cake
The oxidation of aldehydes matter in the dregs of rice.
S2, add water in the Fructus Cannabis separation albumen that step S1 prepares, described Fructus Cannabis separation albumen and water
Mass ratio is 1:15～25；It is heated to 40～55 DEG C, regulates pH to 7.0～9.0 by the NaOH solution of 2.5mol/L,
Add 1.0～5.0% compound protease of amount of described Fructus Cannabis separation albumen quality；After stirring enzymolysis 3～6h,
It is warming up to 80～95 DEG C of enzyme denaturing 10～25min, centrifugal collection clear liquid, it is Fructus Cannabis oligopeptide solution；
The quality proportioning of described compound protease is: pepsin: trypsin: flavor protease
=3～5:2～4:2～4；
S3, the Fructus Cannabis oligopeptide solution that step S2 prepares is carried out electrodialysis, is sloughed inorganic ions after, warp
Membrance concentration equipment concentrates, and obtains Fructus Cannabis oligopeptide concentrated solution；In described Fructus Cannabis oligopeptide concentrated solution solvable
Property solid content is 20～40wt%；By described Fructus Cannabis oligopeptide concentrated solution lyophilization, obtain Fructus Cannabis
Oligopeptide.
Under optimal way, solid-liquid separation described in step S1 uses automatic discharge horizontal screw centrifuge 4000rpm to be centrifuged.
Under optimal way, described in step S3, electrodialytic operating condition is: voltage 75V, enters Fructus Cannabis oligomeric
Peptide solution flow velocity 1.55 ton hour, concentrated stream speed 1.60 ton hour, cooling of electrode water flow velocity 1 ton hour.

Liquid separates and removes crude fibre, starch and fat, and solid-liquid separation removes monosaccharide for the second time；In solid-liquid separation process
In, use automatic clinker-removing horizontal screw centrifuge, improve in Fructus Cannabis grouts and imitate with Protein Separation containing part monosaccharide
Rate, makes monosaccharide mass content in albumen less than 5%, improve and separate purity of protein.
The present invention is when carrying out twice solid-liquid separation, and bits are a lot, and the inventive method requires that slag must be done, water
Divide 10% less than gross mass.
2, the inventive method adds laying particular stress on of Fructus Cannabis grouts mass fraction 1% in Fructus Cannabis grouts lysate
Sodium sulfite, can effectively prevent the oxidation of aldehydes matter in Fructus Cannabis grouts, it is ensured that last gained is low
The color of poly-Gly-His-Lys.
3, the inventive method adjusts pH value to 4.0, makes the albumen in Fructus Cannabis grouts be precipitated completely；Meanwhile,
Regulate with the HCl solution of 2.5mol/L, convenient control pH intensity of variation, the Urtica cannabina L. that the inventive method prepares
Core oligopeptide yield is high.
4, the inventive method Fructus Cannabis oligopeptide clear liquid uses membrance concentration, lyophilization, it is to avoid evaporation and concentration,
The too high generation causing Maillard reaction of spray drying temperature, improves the quality of Fructus Cannabis oligopeptide goods.
5, the inventive method utilizes Fructus Cannabis to extract remaining Fructus Cannabis grouts after Fructus Cannabis oil, by compound
The techniques such as protease hydrolyzed obtain Fructus Cannabis oligopeptide, improve the added value of fructus cannabis, improve simultaneously
The utilization rate of Fructus Cannabis.
The present invention uses through the Fructus Cannabis grouts that deoil of squeezing as raw material, in conjunction with isoelectric point, IP principle, precipitation
Albumen, then obtain Fructus Cannabis oligopeptide through compound protease enzymolysis and cryodesiccated method.Whole process profit
Use pure physical technology, substantially add without chemical composition, with low cost, environmentally safe.
