A process for producing lactoperoxidase, including: a step (1) for bringing one or more milk materials into contact with a cation exchanger having weakly acidic groups as ion exchange groups to thereby effect adsorption treatment; a step (2) for washing the cation exchanger after the adsorption treatment; a step (3) for bringing the cation exchanger after the washing into contact with a leaching solvent to thereby obtain a leaching solution having lactoperoxidase eluted into the leaching solvent; a step (4) for concentrating the leaching solution through an ultrafiltration membrane to thereby effect precipitation in the concentrated leaching solution; and a step (5) for obtaining a lactoperoxidase solution by removing the precipitation from the concentrated leaching solution.

Process for producing lactoperoxidase

A lactulose-containing powder composition is produced by preparing a raw material liquid so that a lactulose content within a powder produced following spray drying is 10 to 50% by weight, a protein content is 0.2 to 9.0 parts by weight per 1 part by weight of lactulose, and a chlorine content is no more than 0.08 parts by weight per 1 part by weight of protein, and subsequently subjecting this raw material liquid to spray drying.
