ABSTRACT:
The extraction and processing of glycoproteins and/or mucopolysaccharides and accompanying substances, from natural substances, such as tissues of animal, cryptogamic, bacterial or other plant organisms, or materials produced by such organisms is disclosed. The substance is treated with water of buffers with a pH value of 7.5 to 9.5, in one or more stages, at between atmospheric temperature and 110.degree. C. The precipitated solids are separated out, while the unprocessed extract is clarified and stabilized, and possibly mixed with fatty substances, obtained, for example, from extracts of organs containing complex lipoids in a natural state of equilibrium. These new, very stable extracts are particularly suitable for aqueous, fatty or dry mixtures, for industrial, medical or cosmetic purposes. One important application involves the preparation of an extract of lactoserum, in liquid, paste or powder form, which is very stable, soluble, and will not precipitate in the presence of heat. Extracts can undergo a final re-sterilization process after packaging.
