Fish gelatin protein extraction device and extraction method thereof

Abstract

The fish gelatin protein extraction device comprises a refrigeration box, the top of the refrigeration box is fixedly connected with a pulverizer, the inner wall of the refrigeration box is fixedly connected with a reaction box, and the front face of the reaction box penetrates through the outer wall of the refrigeration box and communicates with the front face of the refrigeration box; a filtering pipe is fixedly connected to the part close to the bottom of the reaction box, and a filtering device is movably connected to the bottom of the filtering pipe. The interior of the refrigeration box can be continuously refrigerated through the arranged compressor by virtue of the pipeline, so that when impurities of crushed fish skin in the reaction box are removed, the crushed fish skin can be maintained at a proper temperature, and reactions such as degreasing, nucleic acid removal and immunogenicity removal are not influenced; and moreover, multi-stage filtration is matched with ultrafiltration, so that one-step sterilization, interception, molecular weight grading and purification can be realized, the production time is effectively shortened, and the product quality is improved.

Description

technical field [0001] The invention belongs to the technical field of fish gelatin preparation, and in particular relates to a fish gelatin extraction device and an extraction method thereof. Background technique [0002] At present, with the continuous deepening of research on marine organisms, the use of marine organisms to produce collagen-based biomedical materials that meet medical standards has become a research hotspot. How to ensure that the extracted collagen has a complete structure, good biocompatibility, and no immunogenicity This is the difficulty of this type of extraction process. The existing extraction processes mostly use centrifugation, salting out, dialysis and other means to achieve protein purification and final molding, which takes a long time. The obtained collagen contains a large number of molecules with incomplete structures and peptide chains, which affects The final quality of the product is also limited, and its application in the medical field...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a fish gelatin extraction device and its extraction method, to solve the above-mentioned background technology proposed in the existing a kind of fish gelatin extraction device in the process of use, because the existing extraction process mostly by means of centrifugation, salting out , dialysis and other means to achieve protein purification and final shaping, which makes it difficult to remove fat, nucleic acid, and immunogenicity; the steps are cumbersome, the extraction cycle is long; the structure is easily destroyed
