Abstract
The invention provides a method for pretreating gelatin by liming. The grease content of a gelatin finished product can be reduced by treating pickled and rinsed ossein with dilute ammonia water. The ammonia water is used to replace sodium hydroxide, a saponified matter formed after a reaction and emulsified particles formed by the saponified matter and fat have high solubility and can be separated from the ossein easily, and the residual fat content of the ossein is low. The method can reduce the grease content of the gelatin finished product, improve the liming efficiency of the gelatin and shorten the liming circle of the gelatin.
Description
Technical field
The present invention relates to the gelatin technology of preparing, be specifically related to the liming pretreatment process that alkaline process prepares gelatin.
Background technology
Gelatin (gelatin) is a kind of water soluble protein mixture, generally by the collagen in animal bone, ligament, the tendon etc. through acid or alkali partial hydrolysis or in water, boil and produce, crisp or meal shape that colourless or little Huang is transparent, swelling forms gel (moisture for conducting oneself with dignity 5～10 times) in 35～40 ℃ of water.Be widely used in food and make tamanori, photographic film, spectral filter etc.
At present gelatin generally adopts the alkaline process preparation, generally comprises pickling, washing, liming, puies forward step such as glue.
Mineral substance in the aggregate mainly is that some are water-fast, and is dissolved in calcium, magnesium phosphoric acid salt and the carbonate of acid, accounts for 60～65% of total amount, wherein calcium phosphate Ca

The alkaline purification process of soaking raw material with milk of lime becomes " liming ".Liming is the very important ring of alkaline process glue, and raw material is under the effect of alkali, and the tissue of the raw material that can not only loosen, and can dissolve and remove the organism that those influence the gelatin quality is as soluble proteins, pigment etc.The initial rubber protofibril water-swelling of handling through liming, loosen, open, internal bond strength weakens, and cuts off easily, helps the stripping of collagen protein.
In traditional preparation method, usually the ossein after the pickling washing is carried out the liming pre-treatment with caustic soda to ossein before liming, promptly in the qualified pickling ossein of washing, add about 0.5% the lipid acid of rare caustic soda soln, thereby reach the purpose that reduces fat content in the gelatin to remove fat residual in the ossein and to go out by steatolysis.
Yet because the fat and the lipid acid that contain in the pickling ossein mostly are unsaturated fatty acids greatly, the solubleness saponified and and adipogenic emulsified particle saponified by this that forms with caustic soda reaction back is low, is difficult to separate the residual fat quantity height of ossein with ossein; The residual fat quantity height of ossein can very easily generate the lower fatty acid calcium of solubleness with lime reaction in following road liming process, stop up the ossein pore, influences the infiltration of calcium hydroxide to ossein inside, and then influences the effect of liming.Because caustic soda is a highly basic, in the process of degreasing ossein is shunk significantly in addition, the capillary porosity duct in the ossein diminishes, and influences that calcium hydroxide influences the effect of liming to the infiltration of ossein inside in next step liming process.Under identical conditions, make the cycle stretch-out of liming.
Summary of the invention
The object of the present invention is to provide the pretreated method of a kind of gelatin by liming.
Gelatin by liming pretreatment process of the present invention is that the ossein after the pickling washing is handled with weak ammonia, to be used for reducing the fat content of gelatin finished product.
Specifically comprise the steps:
1) in the pickling ossein after washing, adds 3～5% dilute ammonia solution, agitate, make ossein and solution uniform mixing, reacted 24～48 hours, in the process of reacting, agitated once with pressurized air in per 2～4 hours with pressurized air;
2) after reaction finishes, put raffinate, wash 2～4 times, reacted ossein is called G1;
3) 3～5% dilute ammonia solution and 0.5～1% hydrogen peroxide solution were mixed by 1: 1 be made into mixed solution;
4) mixed solution is added react 24～48 hours among the G1, in the process of reaction, agitated once with pressurized air in per 2～4 hours;
5) after reaction finishes, put raffinate, wash 2～4 times, reacted ossein is called G2.
Above-mentioned steps 1) the pickling ossein is 3.6～4.0 to get final product through being washed to the pH value.Can be by repeating above-mentioned steps 4) and 5) 1～3 time, with the reinforcement degreasing effect.
The present invention's aqueous ammonia to replace caustic soda, the solubleness saponified and and adipogenic emulsified particle saponified by this that the reaction back forms is higher, and easily separated with ossein, the residual fat quantity of ossein is few.The inventive method can reduce the fat content of gelatin finished product, improves the liming efficient of gelatin, shortens the liming cycle.
Embodiment
Following examples further specify content of the present invention, but should not be construed as limitation of the present invention.Without departing from the spirit and substance of the case in the present invention, modification or replacement to the inventive method, step or condition are done all belong to scope of the present invention.
