Some methods for preparation and characters during storage at room temperature of powdered pancreatic extract were studied, The obtained results could be summarized as follow:* The yield of pancreatic powder preparations represents:40.6, 28,6, 15.0 and 12.4t for salt dried powder,lyophilized powder, actone extraction powder and precipitated dried powder/l00 mg fresh glandsrespectively.* The salting method for pancreas powder preparationachieved the highest proteolytic activity giving 65.0p/mg fresh gland while the other methods bylyophilization, precipitation and acetone methodsrevealed 38.4, 35.4 and 33.6 p/mg respectively.* The proteolytic and lipolytic activity of the differentforms of powder showed low percentages of decreaseduring storing at room temperature for 3 months.* The bacteriological quality of the different preparedpowders showed low counts for the tested types ofbacteria representing total bacterial count, aerobicsporeformers, coliform and the proteolytic and saccharolytic anaerobic spore form ersoposite to those oflyophilized powder during storage. |
