Problems solved by technology

Using the above-mentioned existing production process, the method of directly boiling large pieces of deerskin leads to a very low glue yield; the traditional gauze filter method is used to remove impurities, although the operation is simple, but the removal efficiency of impurities is low. The amount is small, so the colloid purity is not high and the production efficiency is low; in the process of drying the colloid, the conventional method of drying at room temperature is used, and the processing time is very long, and the colloid is prone to physical, chemical and biological changes. It is inconvenient to take the colloid due to the limitation of the shape; in summary, it is necessary to improve the original production process to make it more efficient and more suitable for industrial production, and the colloid produced has better purity and better quality

specific Embodiment 1

[0025] (1) Hair removal and crushing: Soak the deerskin in boiling water for 15 minutes, scrape off the hair and grease on the surface, and then cut the deerskin into 20cm 2 After the block is placed in alkaline water with a pH value of 8, soak for 48 hours. After soaking, soak the deerskin for 4 hours until neutral; take 100 kg of deerskin that has been cleaned above, and add 2 times the weight of deerskin to the deerskin. After purifying water, use a pulverizer to pulverize to a paste without obvious lumps to obtain a buckskin suspension;

[0026] (2) Heating and concentrating: after heating the above-mentioned buckskin suspension at 120° C. and 0.1 MPa for 2 hours, use 6 layers of 60-mesh gauze to perform coarse filtration to obtain a deerskin glue concentrate;

[0027] (3) Cooling and degreasing: After cooling the above-mentioned buckskin glue concentrate to 4°C, scrape off the white oily lipid formed on its surface;

[0031] (1) Depilation and crushing: soak the deerskin in boiling water for 20 minutes, scrape off the hair and grease on the surface, and then cut the deerskin into 18cm 2 After the block is placed in alkaline water with a pH value of 9, soak for 36 hours. After soaking, soak the deerskin for 6 hours until neutral; take 100 kg of deerskin that has been cleaned above, and add 2.5 times the weight of deerskin to the deerskin. After purifying water, use a pulverizer to pulverize to a paste without obvious lumps to obtain a buckskin suspension;

[0032] (2) Heating and concentrating: heat-treat the above-mentioned buckskin suspension at 125° C. and 0.11 MPa for 2.5 hours, then use three layers of 80-mesh gauze to perform coarse filtration to obtain a deerskin glue concentrate;

[0033] (3) Cooling and degreasing: After cooling the above-mentioned buckskin glue concentrate to 6°C, scrape off the white oily lipid formed on its surface;

Abstract

The present invention discloses an industrial production method of deer-hide gelatin. Deer hide is crushed into paste to enable the deer hide to have relatively high gelatin yield rate in a subsequentheating and concentrating process; an increased cooling and degreasing step can improve pureness of the deer-hide gelatin; a filtration method uses a combination method of a gauze-mesh filtration anda plate-and-frame pressure filtration, can remove impurities more effectively, and is more suitable for the large-scale filtration; after a mold injection, a drying method uses liquid nitrogen vacuumfreeze-drying to ensure active ingredients in the deer-hide gelatin not to be damaged, can prevent microbial contamination, can also enable dry substances to present sponge-porous shaped structure while keeping constant volume and to be extremely easy to dissolve in water to restore original shape, can maximally prevent physicochemical and biological denaturation of the deer-hide gelatin in the drying processes, and morphology of the deer-hide gelatin is very convenient for consumption. The production method is simple and convenient for operations, high in the gelatin yield rate and suitablefor industrial production. The prepared deer-hide gelatin is high in pureness, long in shelf life and very convenient to take.

Description

technical field [0001] The invention relates to a preparation method of deerskin glue, in particular to an industrial production method of deerskin glue, which belongs to the technical field of health food processing. Background technique [0002] Deer are cultivated on a large scale in Heilongjiang, Jilin, Liaoning and other places, which can be used for ornamental purposes and obtain economic value. In my country, deer antler, antler, venison, deer blood, etc. are widely used. Ancient books and modern literature show that deer skin has great practical value, but in reality, deer skin is not only excellent leather raw materials and making specific handicrafts , are mostly discarded, and its edible value has not been fully exploited, resulting in a waste of resources. [0003] The edible and medical effects of deerskin were first recorded in "Compendium of Materia Medica", which records "all leaks and sores, burnt ashes and pig fat are absorbed, five or six times a day, and ...
