Preparation method of egg yolk supernatant powder and protein extraction device thereof

Abstract

The invention discloses a preparation method of egg yolk supernatant liquid powder and a protein extraction device thereof, specifically comprising the following steps: fresh egg washing, protein extraction, clear liquid filtration, concentration, low-temperature sterilization, low-temperature drying, detection, packaging, gold Inspection, packing and storage. The beneficial effect of the present invention is that, compared with the immunoglobulin extracted from mammalian serum, the product extracted from eggs has the advantages of convenient material extraction, relatively simple extraction method, and high yield; the product has good stability, and can produce The antibody is acid-resistant and has stable performance. It can be used for oral prevention of human intestinal infectious diseases. This product has a specific killing effect on pathogenic bacteria that cause acute and chronic pharyngitis and tonsillitis, and inhibits the growth of rotavirus cultured in tissue cells. It can prevent animals from developing rotavirus gastroenteritis, indicating that egg yolk extract can be used as a source of antiviral antibodies to prevent and treat rotavirus diarrhea in infants and young children.

Description

technical field [0001] The invention relates to the technical field of immunoglobulin extraction, in particular to a method for preparing egg yolk supernatant powder and a protein extraction device thereof. Background technique [0002] The traditional immunoglobulin extraction technology is extracted from serum. Since the main source of serum is obtained from animals, the production of immunoglobulin is severely limited by raw materials, and serum is expensive. Through the research of researchers, it is found that immunoglobulin Protein can be extracted from egg yolk supernatant powder. Immunoglobulin is a powder made from fresh eggs through multiple processes. It is the most ideal substitute for serum, and egg yolk supernatant powder has good emulsifying properties. It is an ideal raw material for food, high-grade feed and other products. When preparing immunoglobulin, it needs to go through the protein extraction process. During the temporary storage tank, it is necessar...

Problems solved by technology

[0003] The traditional operation method is to manually rotate the shaking head tube, so that the suction end of the shaking head tube drops with the drop of the liquid level, and stops discharging when it falls to the interface; One end is inserted into the sediment; the traditional shaking head tube is located in the clarification tank, which will hinder the stirring. The long-term force shaking head tube itself will loosen, and the motor load will increase; in order to avoid shaking the head tube when discharging Interference with the stirring shaft, the suction end of the shaking head tube is located on the side of the clarification tank for discharge, but when the suction end of the shaking head tube is about to fall to the interface, the supernatant at the end far away from the suction end of the shaking head tube will flow to the shaking head at a faster flow rate. The suction end of the tube is close, which will cause a large convection between the supernatant and the sediment, which will easily cause unnecessary mixing and directly reduce the quality of the product. In order to ensure the working efficiency, the suction end of the traditional shaking head tube will not be equipped with a filter. network, causing too many impurities to enter the next process, directly affecting product quality
