Valorisation of pork by-products to obtain antioxidant and antihypertensive peptides
(Elsevier, 2023-05-12)
The porcine liver could be used for the extraction of zinc-protoporphyrin (ZnPP) as a natural red meat pigment. During the autolysis process, porcine liver homogenates was incubated at pH 4.8 and 45 °C ...
Influence of pork liver drying on ferrochelatase activity for zinc protoporphyrin formation
(Elsevier, 2022-10-27)
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. The aim of this ...
Zinc Protoporphyrin-Rich Pork Liver Homogenates as Coloring Ingredients in Nitrite-Free Liver Pâtés
(MDPI, 2024-02-09)
This study aimed to investigate the coloring ingredient potential of liver homogenates that form Zn protoporphyrin (ZnPP), a natural red pigment, after anaerobic incubation. Liver homogenates were used ...
Utilization of Porcine Livers through the Formation of Zn-Protoporphyrin Pigment Optimized by a Response Surface Methodology
(MDPI, 2023-05-06)
There is a growing demand for clean-label products. This study aimed to obtain a food-grade coloring ingredient for meat products based on the formation of Zn-protoporphyrin from porcine livers, thus ...
