The following heat penetration data has been generated for a product It is heated by convection. The product contained 10 spores per gram and the capacity of each container is 570 grams. The spores are characterized by values D = 2 minutes and Z = 18F. RT = 240F jh = jc= 1.00 IT = 160F fh = fc = 12 minutes CUT = 5 minutes What processing time must be given for the spore survival ratio to be reduce to one spore per 1000 containers?
