  • Process for manufacturing high .alpha.-lactalbumin content composition
    Patent number: 5434250
    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.

  • Process for manufacturing sialic acids-containing composition
    Patent number: 5270462
    Abstract: The present invention relates to a process for manufacturing a composition containing sialic acids. The process of the present invention comprises the steps of: (a) adjusting cheese whey or rennet whey to a pH of 2-5; (b) contacting the whey with a cation exchanger, to produce an exchanger-passed solution; (c) adjusting the pH of the exchanger-passed solution to a pH of 4 or lower; and then (d) concentrating and/or desalting the exchanger-passed solution. According to the present invention, it is possible to produce a composition having a high sialic acids content at a low cost and in a simple and easy manner on an industrial scale. The high sialic acids content composition thus produced can be utilized as food materials or medical materials and therefore is very useful, industrially.
