  • Process for the recovery of enzyme coagulants
    Patent number: 4368270
    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.

  • Liquid cleaning composition containing stabilized enzymes
    Patent number: 4169817
    Abstract: A liquid cleaning composition containing stabilized enzymes. The composition is an aqueous solution containing from 10% to 50% by weight of solids and including detergent builders, surface active agents, an enzyme system derived from Bacillus subtilis and an enzyme stabilizing agent. The stabilizing agents comprise highly water soluble sodium or potassium salts and/or water soluble hydroxy alcohols and enable the solution to be stored for extended periods without deactivation of the enzymes.
