USE OF A COPRODUCT FROM A PROCESS FOR EXTRACTING LYSOZYME FROM EGG WHITE FOR OBTAINING AT LEAST ONE EGG WHITE BASIC PROTEIN

摘要

The present invention relates to the use of a coproduct derived from a process for extracting lysozyme from egg white, for obtaining at least one basic protein of egg white. This coproduct is a solution obtained at the end of a step of extraction of the lysozyme previously crystallized at basic pH from an eluate containing the egg white protein fraction retained on a cation exchange chromatography support. The present invention also relates to a process for purifying at least one basic egg white protein, comprising an operation for extracting and purifying said basic protein from said co-product derived from a lysozyme extraction process. from egg white.
