Abstract
The invention discloses a production process for gelatin. The production process comprises the following steps: (1) presoaking a skin material by using limewater containing 1 to 3% of calcium oxide for 2 to 4 days; (2) cutting the skin material into small blocks, soaking the small blocks into limewater with a concentration of 2 to 4%, regularly replacing the limewater, during limewater replacement, discharging the used limewater, then washing the skin material with clear water for once, and adding new limewater; and (3) transferring the skin material into a neutralization pool, carrying out continuous stirring, replacing water once every 20 to 40 minutes, after the water is replaced for 8 to 12 times, carrying out water replacement once every 1 to 2 hours, wherein the ratio of a raw material to the water every time is 1: 6, and completing liming in 24 hours.
Description
Technical field
The present invention relates to gelatin technical field, more particularly to a kind of production technology of gelatin.
Background technology
Gelatin be animal skin, bone, white connective tissue in the collagen that contains, process after purified and primary hydrolysis
And a kind of obtained product.Gelatin for yellowish to yellow, the powder or thin slice of translucent micro-strip gloss, without off-odor, wave by nothing
The property sent out.General gelatin is aqueous below 16%, more stable in dry environment gelatin, and in wet condition the easy moisture absorption is by bacterium point
Solve and go bad., in calcination, softening swells until charing, releases the stink of a kind of special burning feather or ammonia for gelatin.Cold
Gelatin indissoluble solution in water, but can absorb water and soften, and easily dissolve in the hot water.It is general that gelatin is insoluble in gasoline, ethanol, chloroform etc.
Logical organic solvent.But the organic acids such as acetic acid, salicylic acid and phthalic acid are dissolved in, urea, thiocarbamide and KBr, iodine is also dissolved in
In changing the aqueous solution such as potassium.
Gelatin is a kind of macromolecular compound, and its molecular weight is about 17500-450000.Gelatin can be divided into photograph by purposes
Gelatin, edible gelatin and industrial gelatine.It is widely used in food, medicine, chemical industry, weaving, printing and dyeing, papermaking, match, five metals,
Furniture and photosensitive material etc. are among conglomerate.
The content of the invention
In view of the foregoing, the invention provides a kind of production technology of gelatin.
To reach above-mentioned purpose, the technical solution adopted for the present invention to solve the technical problems is：
A kind of production technology of gelatin, comprises the following steps：
（1）With limewash pre-soaking cladding 2-4 days containing 1-3% calcium oxide；
（2）Cladding is cut into small pieces, in immersing the limewash of 2-4%, and limewash is regularly replaced, should first by old lime when changing water
Water bleeds off, and be washed once cladding with clear water, adds new limewash；
（3）Cladding is proceeded in neutralization pond, and is stirred continuously down, water is changed once per 20-40 minutes, it is common 8-12 time, later per 1-2
Hour changes water once, and the ratio of raw material and water should be every time 1: 6,24 hours and complete to move back ash；
（4）The calcium salt that collagen and calcium oxide are combined in cladding is removed with sour, then unnecessary sour and generation salt is removed with clear water；
（5）First discharge water to glue pot, be heated to enduring glue minimum temperature, then pour the cladding washed into glue pot, Ran Houzai
Adding water makes cladding just submergence, is to slowly warm up to endure glue temperature, when glue reaches certain weight proportion, i.e., releases glue, weight from bottom
New injection water is endured glue next time, accordingly improves temperature, more previous raising 5-10 degree；
（6）Glue is heated in concentration pan and makes moisture evaporation, and concentration glue is released, and adds preservative；
（7）The gelatin solution for adding preservative is injected in frozen glue disk, freezing in ice salt bath is placed in blocking.
Its further feature is as follows：
Step（1）The middle limewash pre-soaking cladding used containing 2% calcium oxide 3 days.
Step（2）In, the volume of fritter in immersing 3% limewash, and regularly replaces limewash in 10-20cm3.
Step（3）In, cladding is proceeded in neutralization pond, and be stirred continuously down, changed water once per 30 minutes, totally 10 times, with
Changed water once per 1.5 hours afterwards.
Step（4）In, acid is sulfuric acid or hydrochloric acid.
Step（5）In, more previous raising 7-8 degree.
Due to the utilization of above-mentioned technical proposal, the present invention has compared with prior art following beneficial effect：
Obtained gelatin is yellowish to yellow, the powder or thin slice of translucent micro-strip gloss, without off-odor, non-volatility.
