Application

Application Comment Organism
food industry Sus scrofa liver extracts with a high degree of FeCH activity are postulated as potential food ingredients for the meat industry, due to their ability to catalyse Zn-protoporphyrin (ZnPP) formation Sus scrofa

General Stability

General Stability Organism
influence of Sus scrofa liver drying as a stabilisation method on ferrochelatase activity for zinc protoporphyrin formation, overview. The drying process at moderate temperatures close to room conditions (10-20 C) is considered to be an effective method for FeCH preservation since it is possible to stabilise the liver, and the loss of FeCH activity is minimised, drying kinetics and mathematical model fitting Sus scrofa

General Information

General Information Comment Organism
physiological function pork liver contains an endogenous enzyme, ferrochelatase (FeCH), which catalyses the formation of zinc protoporphyrin (ZnPP), a natural pigment of great interest for the meat industry Sus scrofa
