    摘要： The invention concerns a method for producing lactose from lactoserum or a permeate derived from lactoserum ultrafiltration, comprising steps which consist in: (a) substituting at least part of the polyvalent cations of the lactoserum or permeate with monovalent metallic cations, to obtain a lactoserum or permeate depleted in polyvalent cations, (b) substituting at least part of the polyvalent mineral anions and organic acid anions of the lactoserum or permeate, with monovalent anions not capable of forming complexes with the polyvalent cations, said step (b) being carried out prior to or simultaneously with step (a), and (c) crystallizing the lactoserum or permeate derived from steps (a) and (b), to obtain crystallized lactose and filtrates enriched with monovalent metallic cations.

    摘要： In demineralization of a beet sugar solution before boiling as the starting solution with a simulated moving bed chromatographic separator comprising a plurality of packed column units packed with a strongly acidic cation exchange resin in a salt form having an average grain size of 300 to 500 νm and a uniformity coefficient of at most 1.2 as chromatographic packing (separating packing), and each provided with a starting solution feed inlet, an eluent water feed inlet, a withdrawal outlet for a fraction of a component having a strong affinity for chromatographic packing ('strong-affinity component'), and a withdrawal outlet for a fraction of a component having a weak affinity for chromatographic packing ('weak-affinity component'); use is made of circulating pumps, the number of which is at least half of the number of the packed column units, and the beet sugar solution before boiling is demineralized under the following conditions: starting solution feed rate/eluent water feed rate volume ratio = 1/2.5 to 1/3.5, strong-affinity component fraction withdrawal rate/weak-affinity component fraction withdrawal rate volume ratio = 0.5/1 to 1.2/1, and circulating flow rate = 25 to 80 vol. %/hr. based on chromatographic packing in a slowest flow velocity zone in the circulation system, whereby a sucrose fraction having a high sucrose concentration is obtained using a small amount of eluent water with a large throughput.
