Abstract: The present invention relates to a method for manufacturing a modified whey composition, the method having a liquid preparation step of preparing a raw material whey liquid using a whey composition containing whey protein, and a heating step of subjecting the raw material whey liquid to a heat treatment, wherein the liquid preparation step includes a treatment of adding an alkali to the whey composition, the pH of the raw material whey liquid is from 6.8 to 8.0 and the protein concentration in the liquid is not more than 1.3% by mass, the calcium content of the raw material whey liquid that is subjected to the heat treatment is from 400 to 700 mg/100 g of solids, and the heat treatment is performed under conditions of 80 to 150° C. for a period of 30 minutes to 1 second.

Abstract: A processed cheese is produced by producing a natural cheese (N) via an acidification step, a coagulation step and a dehydration step described below, and then using the obtained natural cheese (N) for at least 5% by mass of an ingredient cheese. The acidification step is a step of acidifying a milk to obtain an acidified milk having a pH of 5.8 to 6.4, in which an acid component is added to the milk to achieve the required pH for the acidified milk, the coagulation step is a step of obtaining a curd by adding a milk coagulating enzyme to the acidified milk to cause coagulation, without adding a lactic acid bacterium starter, and the dehydration step is a step of obtaining the natural cheese (N) by separating whey from the curd, and includes an enzyme inactivation step of inactivating the milk coagulating enzyme by cooking the curd to at least 55° C. at a rate of temperature increase of not more than 1° C. per minute.

Abstract: A method for producing a cheese-containing food, the method including a step (1) of heating a soft cheese-containing mixture that contains 70 to 100% by mass of a soft cheese using a Joule heater, and a step (2) of stirring the heated soft cheese-containing mixture under shearing in a high speed shear cooker, wherein the series of steps including the steps (1) and (2) is performed at least twice. With this method, a cheese-containing food having satisfactory quality in terms of smoothness in the mouth and flavor and the like can be produced by using a raw material having a high soft cheese content.

Abstract: The present invention relates to a process for producing a demineralized milk that enables excellent reduction in the amount of monovalent minerals while suppressing any reduction in the amount of divalent minerals, as well as a demineralized milk produced using the above process, a process for producing a cheese and whey from the demineralized milk, and a cheese and whey produced using the above process. In the present invention, a demineralized milk having a significantly reduced amount of monovalent minerals is obtained by passing a raw milk solution through an anion exchange resin in chloride form, and then removing the monovalent minerals contained within the raw milk solution using a membrane separation process. Further, a cheese and whey can be produced by heating the obtained demineralized milk to produce a curd, and then separating the curd from the liquid other than the curd by solid-liquid separation.
