Food Science and Technology Research, 2007 The formation of zinc protoporphyrin IX (ZnPP) and protoporphyrin IX (PP) in porcine heart mitochondria was investigated by fluorescent spectral analysis. The time-course study at 37°C and pH 5.5 with 100μM ZnCl2 showed a linear formation of ZnPP from oxymyoglobin after a lag-period (9h) at the formation rate of 0.46nmol/h. The formed amount of ZnPP is
