Abstract

A neutral solution of casein, legumin, gluten or fibrin or a combination of these, is prepared by obtaining these substances as a highly pure precipitate acid dissolving it in a suitable acid or acid solution. The casein, legumin, gluten or fibrin is subjected to an initial purification by treating it with hot water or steam and then dissolving it in an alkaline or ammoniacal solution, thereby purifying it of fat and albumen. Precipitation is effected with oxyglutaric acid and the precipitate washed, separating from casein the soluble lime salts, or in the case of legumin or fibrin being precipitated to separate the insoluble gluten. The pure precipitate is dissolved in glutamic acid and dilute ammonia to obtain the neutral solution.
