摘要: A method of co-extracting multiple proteins from chicken egg white is provided. Precipitate proteins step-by-step with polyethylene glycol, then separate the proteins via Q Sepharose Fast Flow anion-exchange chromatography. The method of co-extracting multiple proteins from chicken egg white is capable of obtaining five proteins simultaneously in one extraction process, and the protein products have high purity and high recovery ratio. And the method can be carried out only requiring common-used chromatographic filler, greatly reduces production cost, and provides favorable factors for large-scale industrial production of extracting protein from egg white.
