Abstract: A powder composition contains 50 to 95% by weight of a copolymer mixture A of a copolymer 1 and a copolymer 2, and 50 to 5% by weight of a water-soluble cellulose B. The copolymer 1 contains 5 to 60% by weight of polymerized units of methacrylic acid and 95 to 40% by weight of C1- to C4-alkylesters of (meth)acrylic acid. The copolymer 2 contains more than 95 and up to 100% by weight of polymerized units of C1- to C4-alkylesters of (meth)acrylic acid. The powder composition originates from the co-processing of the copolymer mixture A and the water-soluble cellulose B by a drying process of an aqueous dispersion, such as spray drying or freeze drying. Further processing leads to a compressed dosage form.

Abstract: A computer-implemented method for predicting a feedstuff and/or feedstuff raw material is described. The method comprises providing a near infrared (NIR) spectrum of a sample of an unknown feedstuff raw material and/or feedstuff. The absorption intensities of wavelengths or wavenumbers in the spectrum are transformed to give a query vector. A set of database vectors of a population of spectra of known feedstuff raw materials and/or feedstuffs is also provided, and an outlier database vector is removed based on different comparison methods. The similarity between the query vector and each of database vectors is analyzed to produce a similarity value, and the feedstuff raw material and/or feedstuff of the database vector with the highest similarity is assigned to the sample.
