As for this invention, while holding down the decrease of the mineral of 2 value, it regards the offer of cheese and hoei which are produced by the cheese from the desalinization milk and the aforementioned desalinization milk which are produced by the production method and the aforementioned method of the desalinization milk which can decrease from the mineral of 1 value more and the production method and the aforementioned method of hoei. According to this invention, after the liquid doing the raw materials milky lotion in the chlorine type anion exchange resin, from the mineral of 1 value the desalinization milk which is decreased more is obtained by removing the mineral of 1 value which is included in the raw materials milky lotion with membrane method of chemical separation. In addition, heating the desalinization milk which is obtained, after making the card form, it can produce with cheese and hoei by the liquid separating from the liquid other than the card and the aforementioned card hard.本発明は、2価のミネラルの低減を抑えつつ、1価のミネラルをより一層低減することのできる脱塩乳の製造方法、前記方法により製造された脱塩乳、前記脱塩乳からのチーズとホエイの製造方法、前記方法により製造されたチーズとホエイの提供に関する。本発明によれば、原料乳液を塩素型陰イオン交換樹脂に通液してから、原料乳液に含まれる1価のミネラルを膜分離法で除去することにより、1価のミネラルがより一層低減された脱塩乳が得られる。また、得られた脱塩乳を加熱して、カードを生成させた後、カードと前記カード以外の液体とを固液分離することにより、チーズとホエイとを製造できる。
