    (54) FORMING MASS FOR RECEPTION
    ARTIFICIAL.COLUBIC SHELL AND METHOD OF ITS MANUFACTURE
    The invention relates to molding masses that are used to prepare artificial bass casings, as well as to a method for producing these masses. A known molding composition for producing an artificial sausage casing, containing collagen protein {Ij. This molding composition, containing collagen from the head of the sperm whale's head, is made by grinding animal feed and swelling it in lactic acid. An artificial sausage casing is made from this molding material with a comparatively low content of collage, which tanning and simultaneous coagulation in a bath containing coagulation means and as a tanning substance aldehydes in an amount of approximately Known weight is quite expensive due to that collagen protein is used as the main raw material. The aim of the invention is to reduce the mass and preserve the properties of collagen. This goal is achieved by the fact that the molding mass additionally contains a condensation product of at least one compound containing free amino groups with at least one aldehyde in the following ratio of components, wt. %: Collagen protein 10-90 Condensation product of at least one free amino group-containing compound with at least one aldehyde 10-90 The condensation product further contains a polyhydroxy compound in the amount of 1-65% by weight. The mass additionally contains cellulose fibers in the amount of 1-25 wt.%, Dyes in the amount of 1-4 wt.% To its weight, softeners in the amount of 1-25 wt.% To its weight, aldehyde acceptors in the amount of 1-10 weight. % The molar ratio of the compound containing free amino groups to the aldehyde is 1: 0.1-1: 3. The mass contains 30-70 wt.% Collagen protein and 30-70 wt.% Condensation product. Such a mass can be made by a method, the difference of which is that the compound containing free amino groups is condensed with the aldehyde and with the polyhydroxy compound at 25-90 C for 4 4.00 minutes until the condensation product is gelatinized for 9-50 minutes in the presence of a catalyst, after which the obtained condensation product is injected with collagen protein and refined for 1-2 hours. Moreover, a compound containing formaldehyde as an aldehyde, glio, sal, glutaric aldehyde, furfural glyceroldehyde, crete onaldehyde, starch dialdegnd in separation or in mixtures. Glycerin, sorbitol, polyoxymethylene and hydrolysis cellulose are used as polyhydroxy compounds individually or in mixtures. Ammonia, caustic soda, caustic potassium, hexamine, hydroxyl-1-1N, hydrazine, sodium bicarbonate, ammonium carbonate, and also mixtures of these compounds are used as a catalyst. In addition, mineral acids, acid salts, and organic acids are used as catalysts. Example 1. 50 g of urea in 60 g of 38% formaldehyde (molar ratio 1: 0.75} is dissolved in 30 ml of water and 5 ml of 25% ammonia and heated for 3 hours in a boiling water bath The solution becomes more viscous and turbid in this case. This precondensate is pH 8.45. for half an hour. With further stirring, 1 ml of 18% hydrochloric acid is added. The mass obtained contains 21% of the dry substance and a pH of 3.45. After drying the film material is passed through the shower condensate with wood smoke with an admixture of 0.13% formaldehyde. After further drying the sausage shell is pressed and wound on the drum. The diameter of the sausage shell is 47 mg / 1 wall thickness 3.9-102 mm. After 9 days after ripening, the sausage casing has a pH of 5.15, moisture absorption upon softening is 180% and the resistance is forced through a wet casing of 0.85 atm. After 10 days, the sausage casing is passed through a watering unit, where 9% of the sausage casing glycerin is supplied to give softness and elasticity. The casings are suitable for the production of raw and cooked sausages, hot, water at 75 ° C, shrinking up to 50% with a linear shrinkage of 700 g / mm. Example 2. 70 g of urea in 130 g of 38% formaldehyde (molar ratio 1: 1.5) is dissolved in 200 ml of water with 5 ml of 25% ammonia and stirred for 130 minutes at. Then the temperature is raised to 80 ° C and stirring is continued until the viscosity at 20 ° C and the opening of 2 mm reaches 100 s. The total reaction time is about 250 minutes. The gel time during the addition of 10% 3.6% hydrochloric acid is 44 minutes. During the reaction, the pH of the condensation product decreases from 9.5 to 6.0. The pH is adjusted again to maintain polymerization using caustic soda solution. 9. According to example 1, the condensation product is mixed with the fibrous mass of the dermis. The mixture is adjusted to pH 3.45. The dry matter content is 21%. Example 3. 100 g of casein, 1500, g of glycerin (82%), 100 g of ammonia (25%) and 100 g of water are stirred at room temperature b. After the addition of 30 ml of 38% formaldehyde is stirred for 1 h. The viscosity at a hole of 2 mm and a temperature reaches 500 s, pH 10. The gel time at 20 s after the addition of 10% 3.6% hydrochloric acid is 1000 s. The condensation product is soluble in water. Of this condensation product, 35 g is added to 500 g of a fiber mass containing 11% dry matter and having a pH of 3.0. After half an hour of stirring in the mixer, while cooling, 5 ml of 3.6% acid is added and stirred for another half hour. The pH of the mass rises to 4. The dry matter content in the mass is 17%. The pulp has properties typical of pulp fibrous mass, which can be molded into tubular sausage casings by the dry method. Example 4. 100 g of casein, 1500 g of glycerol (82%), 100 g of water and 100 g of ammonia (25%) are stirred for b h at room temperature. Then, 50 ml of 25% glutaraldehyde is mixed in and stirred for another hour at room temperature. The viscosity at a hole of 2 mm and a temperature reaches 500 s, pH 10, the gelatinization time after the addition of 10% 3.6% hydrochloric acid at 20–1000 min. As in Example 3, the condensation product is admixed to the fiber mass of the dermis and the film is again obtained from this mass. A mixture of 500 g of the mass of fiber of the dermis, containing 11% of dry matter.
    and 50 g of condensation product is a mass that can be processed into sausage casings in conventional installations.
    Example 5. 100 g of casein, 1200 g of glycerol (82%), 100 g of water, and 100 g of ammonia (25%) are blended for 6 hours at room temperature.
