Abstract:
Lysozyme was recovered from egg white by continuous precipitation with polyacrylic acid (molecular weight of 4 x 10(6)). Precipitator residence time and shear rate had significant effects on the size distribution of the precipitate, but no clear effects on the compositions. Precipitate mean size increased with higher shear, indicating growth phenomena predominating over breakage. Also, an enhancement of growth rate at small sizes was noted. The Camp number successfully characterized the interaction of shear rate and residence time on the particle size.

The obtained precipitate should be either a pure substance of known composition or easily converted to one by a simple process, such as ignition or drying. In addition, the precipitate should be insoluble and easily filterable. In general, filterability...
