Abstract
Binary method glue preparing technology from pig hairs and side skins relates to the technology with the tankage glue, is a kind of in conjunction with soda acid two methods, utilizes tanning leftover pig burr skin, extracts the technology of high-quality gelatin.This technology is with pig burr skin chopping, degreasing, carries out the alkali pre-treatment earlier after cleaning, and flush away free alkali and caustic solubility impurity carry out sour pre-treatment again, and the flush away acid solution is carried glue under slightly acidic condition then.The iso-electric point of its product is about 7; It is all very high to freeze power, viscosity and transparency, and impurity is few, and is of light color, and production cost is low, and technology is simple, grasps easily.
Description
The present invention relates to the technology with the tankage glue, is a kind of comprehensive soda acid two methods, utilizes tanning leftover pig burr skin to extract the technology of high-quality gelatin.
The method of making gelatin with tanning leftover pig burr leather normally adopts alkali process, and two kinds of technologies can not be applied with uniting two into one.When adopting alkali process, it gives treating processes and is: raw material is shredded,, floods a couple of days with alkali lye through the waterpower degreasing, treat that cladding fully expands in alkali lye after, washing with the mineral acid neutralization, cleans near carrying glue after the neutrality for several times at last again.The viscosity of its product is higher, freezes power about 200 grams, and iso-electric point is 4.7-5.1, is called alkaline process gelatin or Type B gelatin again.
When adopting acid technological process to produce gelatin, it gives treating processes and is: raw material adopts the acid solution dipping after degreasing is cleaned, cladding is fully expanded in acid solution, with the clear water washing for several times, remove solubility in acid impurity again, under little sour condition, carry glue then, its product to freeze power higher, iso-electric point is 7.5-9.Acid process gelatin claims A type gelatin again.
The gelatin of being made respectively by above-mentioned two kinds of technologies only possesses the advantage that technology possessed separately.With the gelatin that alkali process is produced, its characteristic is that the viscosity of product is higher, and the gelatin of producing with acid technological process, its characteristics then be product to freeze power higher.Therefore, two kinds of technologies are owing to lacking the advantage that is possessed each other mutually, so the product of producing does not all reach the requirement of satisfactory to both parties neat U.S..If comprehensive above-mentioned two kinds of technologies are made gelatin, thereby embody the advantage of two kinds of technologies on one's body by a kind of gelatin product, so, this novel process will become a kind of bold trial in the gelatin production.
Purpose of the present invention aims to provide a kind of gelatin manufacturing process of combined acid alkali treatment method, makes product have the advantage of A type gelatin and Type B gelatin concurrently.
The present invention finishes according to following process: with the chopping of pig flaw-piece, waterpower degreasing, clear water washing, with sodium sulphite-milk of lime mixing solutions dipping, make collegen filament obtain the expansion of appropriateness, wash to washing down free alkali and caustic solubility impurity with clear water, flood with hydrochloric acid soln or with inorganic acid solution again, cause cladding in acid solution, fully to expand, carry glue after cleaning with clear water then.
Most preferred embodiment of the present invention:
The chopping of pig burr skin, waterpower degreasing 1-3 time, washing are removed impurity, dirt and salt in the peeling for 3-8 time, carry out alkali with sodium sulphite-milk of lime mixing solutions then and give processing (sodium sulphite 0.2-1%, calcium oxide 0.5-2%), alkali gave treatment time 1-3 days.Give when handling and use hydrochloric acid with carrying out acid behind clear water flush away free alkali and the caustic solubility impurity, also available other mineral acid, as sulfuric acid, sulfurous acid, its concentration is 0.03-2%, 1-6 days acid treatment time.Treat that cladding fully expands the back with clear water washing 5-15 time in acid solution, under pH value 5-6.5 condition, carry glue,, can obtain high-quality gelatin after the oven dry through extracting, evaporating.
The present invention's advantage shows:
1, the isoelectric point of product is 6.5-7.5, can by proper proportion and A type or Type B gelatin mixing application, coacervation can not take place.
2, product to freeze power, viscosity and transparency higher, trace impurity low (one jelly power is the 260-350 gram).
3, it is short that cladding gives the processing cycle, the plant factor height.
4, production cost is low, technology is simple, grasp easily.
5, the waste residue that produces in the production process is few.
Claims (3)
1, a kind of binary method glue preparing technology from pig hairs and side skins comprises cladding chopping, waterpower degreasing, operations such as washing, its characteristics are that with sodium sulphite-milk of lime mixing solutions cladding being carried out alkali earlier gives processing, sodium sulphite concentration 0.2-1%, it is 1-3 days that calcium oxide concentration 0.5-2%, alkali give the treatment time; Clean after free alkali and the caustic solubility impurity, carry out acid again and give processing, concentration of hydrochloric acid 0.03-2%, goes up pot then and carries glue at 1-7 days acid treatment time.
2, according to the described adhesive-preparing technology of claim 1, it is 5-6.5 that its characteristics are to carry the glue pH value; The iso-electric point of product is 6.5-7.5.
3, according to the described adhesive-preparing technology of claim 1, when its characteristics are the row acid treatment, both can adopt hydrochloric acid, also can adopt other mineral acid, as sulfuric acid, sulfurous acid.
