AI Technical Summary
Technical Problem
Existing methods for producing lactoferrin are inefficient, complex, and lack cost-effectiveness, particularly in removing β-lactoglobulin and casein, which are desired to be minimized for allergenicity and purity considerations.
Method used
A method using an anion exchange resin with specific hydrophilic methacrylate-containing copolymers, selectively adsorbing β-lactoglobulin and casein while allowing lactoferrin to permeate, with a resin composition optimized for high selectivity and industrial applicability.
Benefits of technology
The method achieves high-purity lactoferrin production with enhanced selectivity and cost efficiency, suitable for industrial-scale processes.

Abstract
The present invention provides a method for producing a product containing high-purity lactoferrin that can be carried out using relatively simple steps, offers high selectivity and cost efficiency, and is highly adaptable to industrial production. [Solution] A method for producing a product containing lactoferrin in high purity, comprising the steps of: contacting a raw material containing lactoferrin and β-lactoglobulin with an anion exchange resin to selectively adsorb β-lactoglobulin onto the anion exchange resin; and recovering the permeate obtained by permeating through the anion exchange resin, wherein the constituent units of the anion exchange resin are derived from a specific dimethacrylate compound and a specific vinyl compound or a specific methacrylate compound.
