PCT No. PCT/EP94/03857 Sec. 371 Date May 17, 1996 Sec. 102(e) Date May 17, 1996 PCT Filed Nov. 22, 1994 PCT Pub. No. WO95/14394 PCT Pub. Date Jun. 1, 1995In a process for preparing proteins from a protein-containing substance, the substance is dispersed in an alkaline solvent with a pH of over 11.5 and at a temperature of under 30 DEG C. The proteins in the substance are thus dissolved. The resulting solution is then neutralized and the proteins in it are concentrated. To improve the profitability of the process in large-scale manufacture, the protein-containing substance is treated with a protease before dispersion in the alkaline solvent.
