Abstract
The invention provides novel cationic flocculant dispersion polymers that can be utilized in the methods disclosed herein. This invention also provides methods for detecting cationic flocculants wherein said flocculants may be made via a dispersion process, a latex process or a dry polymer process. The flocculants are used to flocculate solids from liquid components of an industrial food process. The detection method involves the use of monoclonal antibodies to determine the presence or concentration of the cationic flocculants in the liquids.
