ABSTRACT:
The present invention relates to a process for manufacturing a composition highly containing .alpha.-lactalbmin. This process comprises adjusting, to pH of 2-4 or 5 or higher, cheese whey, acid casein whey or rennet casein whey; contacting the whey with an ion exchanger, to produce an exchanger-passed solution; and then, concentrating and/or desalting the exchanger-passed solution, if necessary after the exchanger-passed solution is adjusted to a pH of 4 or lower. According to the present process, it is possible to efficiently produce a high .alpha.-lactalumin content composition at low cost and in a simple and easy manner on an industrial scale. The resultant high .alpha.-lactalumin content composition can be used for food materials and medical materials.
