American scientists discover a new method for extracting antibacterial protein

According to foreign media reports, researchers in the United States have found a new method to extract antibacterial protein from eggs without using any organic solvent, such as alcohol or acetone   Ovotransferrin is a kind of monosaccharide protein with strong antibacterial activity, so it can be used to improve food safety Moreover, the peptide derived from the decomposed ovotransferrin also has the ability to control microorganisms Therefore, ovotransferrin and its derived peptide can be used as antimicrobial agents in food In order to extract protein without using organic solvent, the egg white was diluted with distilled water and then homogenized In this way, other components in the egg white can be removed by centrifugation After that, we used ammonium sulfate and citric acid to extract ovotransferrin Scientists concentrated the extracted transferrin for easy use Next, the scientists determined the purity of the extract, verified the properties of the protein and calculated the recovery   The purity of ovotransferrin extracted by citric acid and ammonium sulfate was over 85%, and the recovery was over 83% Scientists say the method is simple and cost-effective The isolated ovotransferrin can be used for a variety of purposes, such as anti-bacterial, anti-cancer treatment and as an iron supplement for human consumption (global)
