Description
Technical field
The present invention relates to gelatin technical field, more particularly to a kind of production method of gelatin.
Background technology
In general, gelatin can be divided into animal glue and leather glue two big class.Wherein, animal glue refer to the skin of animal, bone,
Tendon, angle core and squama etc. process made glue containing organizing of collagen protein after purified and primary hydrolysis, and it can derive from
Traditional pig, cattle, fish are it is also possible to from other class mammal such as sheep, horse, camel.And, the leather in different animals source
Corner material, and the different parts of same animal origin, its obtained gelatin quality all differs, thus can be divided into gelatin again
Industrial gelatine, edible Gelatinum oxhide, pharmagel and photographic gelatin four class.
Mainly the consisting of that 18 kinds of compositions are identical of gelatin and amino acid polypeptide molecule mixture that molecular weight distribution is very wide, point
Son amount is typically tens of thousands of to ten tens of thousands of.In addition to moisture except less than 15% and mineral, in gelatin the content of protein reach 85% with
On, it is a kind of preferable protein sources.Gelatin is class protein obtained from collagen protein partial hydrolysiss, because and collagen protein
There is homology.Collagen protein has bar-shaped triple helix structure, during gelatin is prepared in its partial hydrolysis, collagen this
Plant triple-helix structure to be partially separated and rupture.The aminoacid composition of gelatin is similar to collagen, but the difference because of pretreatment, group
Composition is become to be likely to difference.
Gelatin finished product is colourless or flaxen transparent sheet or microgranule.Because gelatin had both had acidity, there is alkalescence again,
It is a kind of amphiprotic substance, so the micelle of gelatin is powered, under electric field action, it will move to a certain Ghandler motion in the two poles of the earth.
Substantial amounts of hydroxyl is had on gelatin molecule structure, in addition also has many carboxyls and amino, this makes gelatin have extremely strong hydrophilic.
Although gelatin do not dissolve in organic solvent, be also insoluble in cold water, its can in cold water imbibition to itself 5-10 times, and
It is soluble in warm water, cooling can form thermoreversible gels again, and between 24-28 °C, its dissolubility is differed molten point with solidification temperature
Very little, is easily affected and is gone bad by moisture content, temperature, humidity.These speciality having in structure just because of gelatin, gelatin
Also there are many excellent physical propertys, such as jelly power, affinity, high dispersion, low viscosity characteristics, dispersion stabilization, hold
Aqueouss, coating property, toughness and reversibility etc..
Making high-quality gelatin and the process of collagen protein is exactly to destroy stable collagen fiber by suitable processing method
Intermolecular and intramolecular covalent cross-linking and non-covalent bond, discharge tropocollagen molecule, then make to stablize collagen spiral shell by heating
The hydrogen bond of rotation ruptures thus discharging gelatin.So, two in gelatin preparation process committed step is exactly at the early stage of raw material
Manage and endure glue to extract.At present, the traditional method producing gelatin mainly has acid system, alkaline process, enzyme process and four kinds of soda acid binary method, mostly
It is all with the skin of animal, bone and tendon as raw material, by classification, wash leaching, defat, neutralization, hydrolysis, filtration, concentration, gel, baking
More than ten procedures such as dry, pulverizing are made.Production method the most frequently used in the factory at present is alkaline process and acid system.With acid system production
Gelatin is type A gelatin, and the gelatin being produced with alkaline process is type B gelatin.The Gel Strength of Gelatin that acid system produces is high, viscosity is low；Alkaline process produces
Gel Strength of Gelatin is low, viscosity is high.Not only high jelly power but also full-bodied high-quality both can not be reached.
It is obvious that above-mentioned prior art exists, pollution is big, production cost is high, product viscosity is low, viscosity degradation rate high, jelly
The defects such as power deficiency.It is badly in need of the new technique of drawbacks described above to be overcome in commercial production.
Content of the invention
In view of the foregoing, it is an object of the invention to provide a kind of production method of gelatin, to solve above-mentioned existing skill
The various problems that art exists, improve the production efficiency of gelatin further, save production cost, improve the quality of product, make product
Quality reach standard.
For reaching above-mentioned purpose, the technical solution adopted for the present invention to solve the technical problems is：
A kind of production method of gelatin, including pre-treating technology, endures glue, filtration, ion exchange, membrane filtration, straight panel drying, goes out
Bacterium, gum deposit, drying, pulverizing, inspection and finished product are it is characterised in that the processing step of described pre-treating technology is：
(1) using dermatome, skin material is cut into strip, reaches washing tank with delivery pump；
(2) alkali process, add water in skin material, then plus liquid caustic soda, control solution mass concentration be 0.8-1.0%；
(3) hydrogen peroxide pretreatment, in (2), alkali liquor adds hydrogen peroxide and raw material skin is processed, and soaks 5-8 under room temperature
My god；
(4) severe edema due to hypofunction of the spleen separates, and reclaims liquid caustic soda；
(5) in washing tank, skin material is washed to solution ph to reach between 6.5-7.5；
(6) pickling：It is 1.5-2.5 that salt adding acid makes the pH value of solution, and soak time is 12-36 hour；
(7) neutralize：First wash with water and move back acid 2 to 3 times, add after liquid caustic soda stirs 2 hours and soak 3-4 hour again；
(8) finally washing pH value when carrying glue is 4.5-6.0.
Its further feature is as follows：
In step (3), the consumption of hydrogen peroxide is the 5%-9% of skin material quality, and the mass concentration of hydrogen peroxide is 5-20%.
In step (3), the consumption of hydrogen peroxide is the 7% of skin material quality, and the mass concentration of hydrogen peroxide is 15%.
Soak time in step (6) is 20-22h.
Soak time in step (6) is 21h.
It is 7 that skin material is washed to solution ph in washing tank by step (6).
In obtained finished product, the jelly force intensity of previous three passes glue all reaches 220g, the equal 5mPa.s of Bo Shi viscosity.
The pH value that step (8) finally washes when carrying glue is 5.3.
Due to the utilization of technique scheme, the present invention compared with prior art has following beneficial effect：
（1）First skin material is cut into strip, then carries out alkali process, it is possible to increase skin material specific surface area and the contact area with liquid caustic soda, carry
The loose degree with expansion of high collagen fiber.
（2）Quick lime is replaced to soak using liquid caustic soda, liquid caustic soda is recyclable, and has saved in follow-up water-washing step
Water consumption.
（3）Replace sodium sulfide that raw material skin is lost hair or feathers and expansion with hydrogen peroxide, not only can effectively solving sulfur
Change pollution environment, the problem introducing new impurity and affecting gelatin quality that sodium exists, and a certain degree of changing can also be played
Kind gelatin color and luster, the effect of bacteriostasis antibiosis.
（4）The temperature control of alkali process at room temperature, with respect to more harsh to temperature requirement in prior art,
Present invention saves mass energy.
（5）Cut the whole pre-treating technology after skin all to complete in same washing in skin tank, farthest decrease wave
Take and stain, saved production cost and plant investment cost.
