Abstract: The heat-stable fraction of covalently immobilized peroxidase on/in porous glass beads in an environment of dodecane was studied as a bioindicator for evaluation of thermal processes under conditions of pasterurization. The verified bioindicator had a z value of 10.1-degrees-C and a Dref (at 70-degrees-C) of 22 min. At processing temperatures of 70-degrees-C and 80-degrees-C, the lethalities (F)bio as read from the bioindicator agreed very well with the target Ft10.0 values calculated from the time temperature data according to the general method.
