Abstract: A production method for an MP whey is provided, that enables preparation of both of a high GMP-content composition and a usable MP whey from an ordinary MP whey. The problems can be solved by a production method for a glycomacropeptide-containing composition, that includes a step of acquiring a solution containing glycomacropeptide, that includes a glycomacropeptide content of 10% by weight or higher in the protein total amount by condensing and/or applying diafiltration to a microparticulated whey solution.

Abstract: A denture brush that includes a frame having a plurality of wall pieces disposed at an outer circumferential part of a flat plate-shaped base, and first bristle tufts are arrayed on the wall pieces, and second bristle tufts 6 are arrayed in a center region of the base, and third bristle tufts are arrayed on an outer circumferential side of the second bristle tufts. When the denture brush is not housed in a holder, the wall pieces are positioned radially along the outer circumferential part of the base so as to be horizontal with respect to the base. When the denture brush is housed in the holder, the wall pieces are supported by a wall surface of a denture-brush-housing portion of the holder, and are positioned so as to stand upright with respect to the base.

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.
