    摘要： There is provided a method for producing hydroxypropyl methyl cellulose acetate succinate (HPMCAS), including an esterification step of reacting hydroxypropyl methyl cellulose with an acetylating agent and a succinoylating agent in the presence of an aliphatic carboxylic acid in a kneader reactor equipped with two or more stirring blades rotating around their own axes and orbitally revolving, to obtain a reaction product solution containing HPMCAS; a precipitation step of precipitating the HPMCAS by mixing the reaction product solution with water to obtain a suspension of the precipitated HPMCAS; and a washing and recovery step of washing the HPMCAS in the suspension and recovering the washed HPMCAS. Further, there is provided HPMCAS having yellowness at 20° C. of 15.0 or less, as determined in a 2% by mass solution of the HPMCAS in a mixed solvent of dichloromethane, methanol and water in a mass ratio of 44:44:10.

    摘要： A stirring implement includes a stirrer having a single stir rod defining a generally triangular shape at a distal end thereof, a rotating guide defining a slot, wherein the single stir rod of the stirrer is inserted through the slot of the rotating guide such that the single stir rod is positioned at an angle with respect to a planar surface of the rotating guide, and a lid releasably engageable to the rotating guide. The stirrer has a handle at a proximal end thereof and the handle rotates circumferentially beyond an outer perimeter of the lid. An apex defined by the single stir rod travels circumferentially along an inner wall of an outer perimeter of a container attached to the lid.

    摘要： A mixing beater for a stand mixer includes a collar configured to removably couple the mixing beater with the stand mixer. A frame is coupled with the collar and includes a pair of opposing first and second arms. The first and second arms are coupled at their respective distal ends by a frame tip. A central axis of the mixing beater extends through the frame tip, between the opposing first and second arms. A plurality of ribs extends between the first and second arms. Each rib has a rib central axis that extends orthogonal to the central axis of the mixing beater and each of the plurality of ribs is spaced from an adjacent rib to define a space between adjacent ribs.
