METHOD FOR PRODUCING DESALTED MILK

摘要

PROBLEM TO BE SOLVED: To attain an effective operation of a desalting method of a combination of an electric dialysis with ion exchange resin added with a softening treatment, capable of reducing the amount of waste liquid from whole process to reduce an installation and cost necessary for the waste liquid treatment and also reducing the effect of the waste liquid to an environment in the method for producing desalted milks by combining the softening treatment and the electric dialysis, without being limited by a ratio of mono-valent/divalent cations of the treated milks and the order of integrating a nano-filtration concentration. SOLUTION: This method for producing the desalted milks by desalting raw material milks with the electric dialysis after its softening treatment is provided by using a combined material of a component of a solution obtained by removing polyvalent cation from a regenerated waste liquid of the ion exchange resin for the softening treatment and components in a salt water as a concentrated salt water obtained by the electric dialysis, as a regenerating agent of the ion exchange resin for the softening.
