ABSTRACT:
A process for improving the recovery of enzyme coagulants from animal organs comprising the steps of adding a polar solvent having a surface tension in the range of about 18 to 72 dyne.cm.sup.-1 to the finely divided organs and thereafter adding salt solution to the organ/polar solvent mixture to extract the enzyme coagulants. Subsequently, the extract is activated by lowering the pH to a value in the range of 3.2 to 4.8 and gel-like substances such as mucin, are removed. The process results in an improved enzyme yield and minimizes the loss of enzyme activity to improve the stability.
