  • Patent number: 10918675
    Abstract: A water resistant enhanced wound healing film includes components by mass volume concentration of: 5-10 mg/L of ultra-fine eggshell powder, 50-500 mg/L of ultramicroshell membrane powder or shell membrane soluble protein, 5-30 mg/L of lysozyme, 5-10 mg/L of chitosan, 0.05-5 mg/L of glycerin, and 0.1-5 mg/L of polymer polysaccharide. Also, a preparation method of the water resistant enhanced wound healing film is disclosed. The whole raw materials of the present invention are non-toxic and have good biocompatibility; the raw materials include eggshell, shell membrane and soluble mixed protein thereof, and lysozyme in residual egg white. In the present invention, various components of the eggshell waste are sufficiently used. The wound healing film has good water resistance, mechanical properties, antibacterial activity and protein absorption capacity, and low degradation rate.

  • Patent number: 8574883
    Abstract: 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.
