Description
Technical field
The present invention relates to technical field of preparation of gelatin, more particularly to a kind of production method for digesting manufacture gelatin.
Background technology
Current domestic skin gelatin manufacturing enterprise continues to use traditional soda technique glue, and technological process includes：Caustic dip → move back alkali
Washing → neutralization → washing → heating carries glue → refinement treatment → concentration → evaporation → sterilizing → plastic squeeze, drying, this technique side
The method production cycle needs 7-10 days, and time-consuming, and occupation of capital rate is big；Caustic dip process needs to build substantial amounts of caustic dip pond, takes up an area face
Product is big, and investment is big, and the process often produces one ton of gelatin in addition：Water consumption 400-600 tons, wastewater discharge is big, caustic dip processing
5-7 ton liquid caustic soda is needed, liquid caustic soda price is 2000-2500 yuan/ton at present, and cost of supplementary product is high；Process conditions are harsh, easily by environment
Temperature is influenceed, unstable product quality, and 30%-40% gelatin is needed in high temperature when carrying glue（80-100℃）Under the conditions of produce, energy
Consumption is high, the shortcomings such as good glue rate is low.
The content of the invention
The goal of the invention of the present invention is：For above-mentioned problem, there is provided a kind of producer for digesting manufacture gelatin
Method, gone by using pickling acidolysis unless collagen impurity, makes the expansion of the raw materials such as animal cladding soft, by the acidolysis of some cycles
Enzymolysis carries glue under cryogenic afterwards, and high viscosity, the high gelatin for freezing power can be produced by way of acidolysis and enzymolysis are combined
Product, to solve the deficiency present in prior art.
The technical solution adopted by the present invention is as follows：A kind of production method for digesting manufacture gelatin, including pickling processing, it is special
Sign is, by raw material after pickling is handled, carries out enzymolysis and carries glue, wherein, it is desirable to the acid used in pickling is inorganic acid, used in enzymolysis
Enzyme be acid protease, the raw material after pickling is broken into the particle of certain particle size before enzymolysis.
In the present invention, the inorganic acid is dilute sulfuric acid, and the concentration of dilute sulfuric acid is 1-6wt%.The concentration of acid and the species of acid
Selection whole pickling processing procedure is had a great influence, when acid excessive concentration when, then be also easy to produce carburizing reagent, cause raw material by
Damage, gelatin Quality Down；When the concentration of acid is too low, then again acid hemolysis process can be made slow, pickling poor processing effect, after being unfavorable for
The enzymolysis glue process of phase.The applicant obtains by long-term experimental study：The pickling treatment effect of strong acid is better than middle strong acid
（Phosphoric acid etc.）With the pickling treatment effect of weak acid, and in strong acid, preferably dilute sulfuric acid is that pickling processing is sour, dilute sulfuric acid it is dense
When degree is in the range of 1-6%, the concentration of dilute sulfuric acid is higher, and acid hydrolysis is stronger, and processing speed is stronger, and pickling treatment effect is just
It is better, and exceed the scope, then it cannot get the effect, therefore, in the present invention, the concentration of dilute sulfuric acid is 1-6wt%.
In the present invention, the broken granularity of raw material is 20-100 mesh.Because traditional production technology never focuses on raw material
Broken granularity, also do not carefully studied raw material granularity has what to influence on gelatin process processed, thus causes by tradition gelatin
The gelatin that technique obtains it is of low quality, yield is relatively low, and the wasting of resources is than more serious.And the present invention to the granularity of raw material by entering
After row is carefully studied, following achievement in research is obtained：For the granularity of raw material in 20-100 mesh, glue speed is fast under raw material, what it was obtained
Gelatin quality is higher, and the yield of gelatin is improved, and within the range, the broken granularity of raw material is thinner, in enzymolysis glue mistake
Cheng Zhong, lower glue speed is faster, and yield is higher, and the quality of the gelatin of acquisition is higher, if the granularity that raw material crushes is less than the scope（I.e.
The broken granularity of raw material is too thin）, then emulsion can be produced during glue is digested, during thus causing to carry glue in the later stage
Be not easy gelatin being separated by filtration, larger difficulty caused to later stage refinement treatment process, and the gelatin obtained after refinement treatment its
Impurity content is higher, and gelatin quality is relatively low；If the broken granularity of raw material is higher than the scope（That is the broken granularity of raw material is too thick）, then
It can cause under raw material during digesting glue that glue speed is slow, yield is relatively low.Therefore, the broken granularity of raw material should be in above-mentioned model
In enclosing.
Further, in pickling processing, temperature during pickling is 15-25 DEG C.The selection of pickling temperature is critically important, it is too high or
It is too low to influence whole pickling processing procedure, specifically, if pickling temperature is too low（Less than above range）, inorganic acid can not
Acid hydrolysis has been given play to completely, has caused pickling effect poor, is unfavorable for follow-up enzymolysis and is put forward glue process；If pickling temperature is too high（It is super
Cross above range）, acidolysis is too strong during causing pickling, and collagen is lost in larger, and collagen quality sustains damage, and influences follow-up bright
Glue yield.Test, which is studied, by many experiments show that pickling temperature is at 15-25 DEG C, pickling best results, can be in acidolysis speed
A better balance value is obtained between rate and yield.
Further, in enzymolysis carries glue, the addition of acid protease is material quality（25-60）/100000.It is acid
The addition of protease is important, adding too much or it is too low gelatin can be impacted, specifically, if addition
During acid protease deficiency（Less than the scope）, during enzymolysis carries glue, lower glue speed is slow, and the gelatin finally given contains
Measure relatively low, yield decline；If during the acid protease excess of addition（Beyond the scope）, after enzymolysis carries glue, obtained gelatin
Quality be affected, cause gelatin quality reduction.Therefore, the addition of acid protease needs within the above range, Cai Nengbao
Demonstrate,prove the quality and yield of gelatin product.
In the present invention, the production method of enzymolysis manufacture gelatin comprises the following steps：
Step 1, pickling processing, carry out pickling processing by raw material and dilute sulfuric acid, are soaked at a certain temperature according to a certain percentage
Raw material after acid；
Step 2, back sour water are washed, and raw material is washed after venting acid solution, then neutralize washing raw material, adjust the pH value of raw material, in venting
After liquid, obtain neutralizing the raw material after washing；
Step 3, raw material are crushed, and the raw material after obtained neutralization washing is sent into pulverizer is crushed, and obtains having certain grain
The particle of degree；
Step 4, enzymolysis glue, the particle that step 3 is obtained are placed in reactor, acid protease and water are then added, one
Determine to carry out enzyme digestion reaction at temperature, the pH value of mixture in regulation reactor, after the completion of question response, adjusting the pH value of mixture makes
