Abstract
A heparin-enriched material capable of long-term storage and particularly adapted for use as a raw material in processes for the extraction of heparin is produced by storing the animal organ material for a period of 0.5 to 15 hours (preferably 4 to 6 hours) at a temperature of 10.degree. to 50.degree. C. (preferably 30.degree. to 50.degree. C.), then injecting steam to effect a heat treatment at a temperature between 75.degree. and 100.degree. C. The heat treatment precipitates heparin-containing aggregate which is filtered from the aqueous phase and dried to a dry substance content of 90 to 95%.
