Title: Improvements in product containing casein and process of producing same
Filed: 1934-12-08
Abstract: Compositions containing acid-precipitated casein are made by mixing the casein with sufficient water to bring the water content of the casein to 25--32 per cent, and with a substance capable of reacting with the casein, the materials being thoroughly incorporated together by kneading and extruding the moist mass while subjecting it to sufficient heat and pressure to plasticize and homogenize the materials.  The product may then be dried and ground, and may be used in paints, sizes, adhesives, medicinal preparations and food products.  Examples are given of compositions: of moist acid-precipitated casein and sodium bicarbonate, which may be dissolved in water and used as a glue or size, e.g. in admixture with lime and sodium fluoride; of the casein and other sodium or potassium salts, e.g. borax, sodium fluoride and potassium phosphate; of the casein and ferric hydroxide for medicinal purposes; of the casein, iron lactate and sodium bicarbonate; of the casein, copper sulphate and sodium bicarbonate; and of the casein and naphthionic acid, to which may be added lime, sodium carbonate and trisodium phosphate for the preparation of a glue.  To the compositions may also be added other materials, e.g. wood, flour, whiting, clays, pigments, dextrine, starch, hide glue, vegetable seed meals, glycerine, or waxes.ALSO:Compositions containing acid-precipitated casein are made by mixing the casein with sufficient water to bring the water content of the casein to 25--32 per cent, and with a substance capable of reacting with the casein, the materials being thoroughly incorporated together by kneading and extruding the moist mass while subjecting it to sufficient heat and pressure to plasticize and homogenize the materials.
