Abstract: The present invention relates to a method for producing a composition containing ?-casein glycomacropeptide including: (A) preparing an aqueous solution containing a milk ingredient having a pH of 4 to 9; (B) pretreating the aqueous solution to obtain an aqueous solution containing carbonate (hydrogen) ions and metal ions; (C) subjecting the pretreated aqueous solution to membrane treatment using a membrane having a molecular weight fraction of 9,000 Da or more and 300,000 Da or less. According to the method, it is possible to obtain a composition containing GMP, which is simple to operate and has a high yield regardless of whether the starting material is cheese whey or whey protein concentrate.

Abstract: Manufacture a powder with high milk-derived complex lipid content that contains milk-derived phospholipids and milk-derived ganglioside at high concentrations, which contains protein by 15 to 35 percent by dry weight and fat by 45 to 60 percent by dry weight, wherein the content of milk-derived complex lipids is 20 percent by dry weight or more, and which can be utilized as a material for functional food, mother's milk substitute or drug, by means of adjusting the pH value of a butter serum or butter serum powder reconstituted liquid to a range of 4.0 to 5.0, adding calcium chloride to promote coagulation of protein, removing the produced sediments, filtering the supernatant by means of ultrafiltration or microfiltration, and then drying the obtained concentrate.

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.

Abstract: Disclosed are tetraphenyl porphyrins which are beta-substituted by fluoro or chloro and/or bear electronegative substituents on the phenyl including one or two water solubilizing substituents. The new porphorins are particularly suitable as catalysts in a variety of oxidative reactions and methods.
