    Patent number: 5861291
    Abstract: The present invention relates to an advantageous and novel method of producing pancreatin which contains low amounts of residual organic solvent, and more particularly to a method which is more environmentally friendly than conventional methods of pancreatin production. More specifically, the present invention relates to a method which utilizes quantities of organic solvents which are about 10 times lower than that of conventional methods. A preferred method of pancreatin preparation, whereby a pancreatic past is autolysed, decontaminated, subjected to an ultrafiltration, dried and then defatted is herein disclosed. The present invention further relates to a pancreatin preparation which contains low amounts of residual solvent. This amount is about 15 to 30 times lower than pancreatin preparation obtained with these conventional methods.
