Abstract
The invention discloses a kind of method that persimmon tannin is extracted from persimmon, comprise the steps:Feedstock treating, ultra high pressure treatment, ultrasonication, digest, be drying to obtain finished product.On the other hand the present invention improves product yield by using two kinds of combinations of extracting mode, on the one hand shortening extraction time.
Description
Technical field
The present invention relates to a kind of extracting method of persimmon tannin, and in particular to a kind of method that persimmon tannin is extracted from persimmon.
Background technology
Persimmon is Ebenaceae berries temperate zone deciduous fruit tree, originates in China, in existing more than the 1000 years plantation history of China.
Current China cultivated area is maximum, and persimmon fruit yield is most.The tender succulence of persimmon, sweetness are tasty and refreshing, nutritious.Have sweet persimmon and
Two kinds of puckery persimmon, puckery persimmon is not directly eaten, it is necessary to by treatment of taking away the puckery taste.Sweet persimmon can be eaten raw, it is also possible to cook dried persimmon, persimmon vinegar, persimmon
Wine etc., persimmon leaf can cook persimmon tea.Persimmon contains substantial amounts of tannin.Tannin is called tannic acid, is a kind of polymer of polyphenol, is a kind of
It is polymerized polyphenol polymer by catechol etc., the phenolic hydroxyl group containing many ortho positions, thus have many functions.Seguin is in 1796
Year define a buzzword Tannin (tannin) represent the chemistry that rawhide can be made in plant flooding extract to be converted into leather into
Point.Gradually recognized by research later, tanning effect can be produced in plant extract is a series of polyphenol compounds, its
The molecular weight of active ingredient is between 500-3000.Tannin is faint yellow last without crystalline flour to light brown also known as tannic acid, belongs to polynary benzene
The complex compound of phenol.Vegatable tannin is renamed as plant polyphenol (plant polyphonies) again, that is, being present in persimmon fruit makes it
It is referred to as persimmon tannin (kaki tannin) in the aldehydes matter of astringent taste.Persimmon tannin have sun-proof moisturizing, anti-wrinkle cosmetic, antisepsis and sterilization,
Prevention of cardiovascular disease, adsorbing metal ions and with the various functions such as protein interaction.
At present, persimmon tannin is mainly derived from natural extraction or chemical synthesis.The traditional common method for extracting persimmon tannin is main
There is acid to carry, alkali carries and water extraction etc., wherein in the majority with hot water extraction, acid, alkali carries take the structure that can all destroy persimmon tannin, while also can
Content on sulfate radical produces influence；And the recovery rate of hot water extraction is typically relatively low, it is difficult to meet Production requirement.Typically by water
Or after alcohol extracting, need to particularly be used and steam by the serial flow such as sufficient absorption, drip washing, wash-out after extract solution is concentrated under reduced pressure
Distilled water repeatedly drip washing to eluate phend-sulphuric acid inspection do not measure sugar, operating process is cumbersome, otherwise dried in the later stage
Because persimmon tannin concentrate contains, sugared part ratio is too high in journey, and drying machine " viscous wall " is serious, it is impossible to reach dry materials pulverized solid
Change.Chinese patent CN102229628B, discloses a kind of method that persimmon tannin is produced from persimmon, by persimmon by cleaning screen
Select, squeeze the juice, add yeast Concentrated fermentation, ultrasonic-leaching, concentrate, be dried to obtain tannin acid product, although nothing in production process
High temperature is needed, without the series flow such as absorption, drip washing, wash-out, by adding the sugar in yeast fermentation decomposing materials, is not destroyed easily
Hydrolysis or the effective ingredient of oxidation characteristic, but the content and yield of product are obtained than relatively low.
The content of the invention
In order to overcome the deficiencies in the prior art, it is to avoid the prolonged high-temperature heating in the extraction process of persimmon tannin, cause
Tannin is oxidized, and influences the yield of final products, the invention provides a kind of method that persimmon tannin is extracted from persimmon.
The present invention is achieved through the following technical solutions：
A kind of method that persimmon tannin is extracted from persimmon, comprises the steps：
1) Feedstock treating：It is divided into ripe persimmon cleaning by seven or eight, crushes；
2) ultra high pressure treatment：The 5-10 times of pure water of weight portion, pressure 350MPa, action temperature are added in persimmon after broken
40-50 DEG C of degree, ultra high pressure treatment 2-5min；
3) ultrasonication：By step 2) obtain solution, ultrasonication 5-10min, 40-50 DEG C of operative temperature, power
It is 300W；
4) digest：Step 3) solution that obtains, it is placed in sealed fermenter, pectase, apple starch that addition has been activated
Enzyme, the complex enzyme of pectin lyase are digested, and enzymolysis time is 20-30 minutes, and hydrolysis temperature is 43-45 DEG C, pectase, apple
Fruit amylase, the weight ratio of pectin lyase are 5:3:2, complex enzyme addition is 40-80mg/kg；
5) by step 4) concentrate after the filtering of the enzymolysis liquid that obtains, spray drying obtains persimmon tannin.
Compared with prior art, the invention has the advantages that：
1st, the present invention uses ultra high pressure treatment persimmon raw material, is kept for a period of time in predetermined pressure, makes inside and outside raw cell
Pressure reaches balance (active ingredient reaches dissolution equilibrium) rapid release afterwards, intraor extracellular osmotic pressure difference is increased suddenly, carefully
The active ingredient of intracellular passes through cell membrane (structure of cell membrane changes under super-pressure), is transferred to extracellular extract solution
In, reach the purpose for extracting target component.Ultra high pressure extraction avoid the active ingredient caused by long-time high temperature change,
Loss and the reduction of physiologically active, simultaneously as super-pressure is carried out under closed environment, do not have the volatilization of solvent, no
Environment can be polluted.It is a kind of method for safely and effectively extracting active material.
2nd, the present invention then uses ultrasonic wave extraction again after using ultra high pressure treatment raw material, what ultrasonic wave extraction was utilized
It is strong mechanical shearing effect, promotes the dissolution of persimmon tannin, the present invention passes through to use two kinds of combinations of extracting mode, on the one hand
Extraction time is shortened, product yield is on the other hand improve, using the method for the present invention, persimmon tannin content more than 95% is carried
Take rate more than 75%.
3rd, the present invention carries out compound ferment treatment to persimmon extracting liquid, can fully decompose the sugar in persimmon, makes macromolecular
Material fragments into small molecule composition.
4th, present invention, avoiding the series flow such as column chromatography, absorption, drip washing, wash-out, glucide is decomposed by complex enzyme,
Direct spraying is dried after extract solution is concentrated under reduced pressure, and operation is simple.
