Abstract

PURPOSE:To obtain water-soluble milkprotein having re-coagulate properties of aqueous solution by di- or tri-valent metal ion, by desalting of calcium in raw milk and drying. CONSTITUTION:Keeping pH of raw milk or processed milk >=6.0, calcium bonded with casein in milk is highly desalted by, for instance, electrodialysis. Next, resultant desalted milk is condensed by ultrafiltration, as desired, dried by freeze-drying or spray-drying, etc., or rennin is added to the resultant desalted milk, subjected to a rennet reaction and dried.

The present invention is soluble in water, has an extremely low content of metals such as Na, has almost no musty odor, and has an aqueous solution that coagulates with divalent or trivalent metal ions. An object of the present invention is to provide a method for producing a water-soluble milk protein having the following properties.

Another feature of the present invention is that while the pH of milk or processed milk is maintained at 6.0 or higher, calcium bound to casein in the milk is highly desalted or further concentrated.

In the present invention, milk or processed milk as a raw material is lowered to pH 6 with an alkali, such as NaOH or KOH.
.. While keeping the temperature above 0, the milk is desalinated to highly desalinate the calcium bound to casein in the milk. This desalting of calcium prevents curd formation due to coagulation even after casein is converted to para-casein by addition of starter and milk-clotting enzyme.

Therefore, by drying the raw milk after desalting calcium as described above, water-soluble milk protein powder can be obtained, and by drying the raw milk that has been subjected to the rennet reaction after desalting, it is possible to obtain water-soluble milk protein powder. A soluble rennet milk protein powder is obtained.

In order to carry out the desalting treatment in the present invention, it is preferable to use an electrodialysis method, which usually makes it possible to desalt 90% of the calcium in milk. In other words, by desalting calcium in this way, the calcium bound to casein in milk is highly desalinated. Since rennet reaction does not cause coagulation into a card, even if it is dried and powdered, it remains soluble in water.
