Effects of post mortem pH and salting time on Zinc-protoporphyrin content in nitrite-free Serrano dry-cured hams
(Elsevier, 2020-03-09)
There is a growing demand for clean label products and thus the elimination of curing additives in various dry-cured meats is of interest while maintaining colour characteristics. This study was aimed ...
Zinc-protoporphyrin content in commercial Parma hams is affected by proteolysis index and marbling
(Elsevier, 2018-02-01)
The contents of zinc-protoporphyrin (ZnPP) and heme in twenty-four sliced Parma hams made without the addition of curing agents were determined. Expressed on a dry weight basis, ZnPP averaged 45 mg/kg ...
Effect of high hydrostatic pressure on the oxidation of washed muscle with added chicken hemoglobin
(Elsevier, 2019-04-19)
The role of chicken hemoglobin in lipid oxidation of washed chicken muscle exposed to high hydrostatic pressure (0, 200, 400 and 600 MPa) was examined. The observed decrease in redness was higher with ...
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 ...
Dynamics of Microbial Communities in Nitrite-Free and Nutritionally Improved Dry Fermented Sausages
(MDPI, 2023-04-21)
Dry fermented sausage innovation trends are linked to consumer preferences for clean label and sodium-reduced foods. This study aims to evaluate the effect of the formulation and production process ...
Influence of ultrasonic application on the enzymatic formation of zinc protoporphyrin
(Elsevier, 2023-02-03)
Ferrochelatase (FeCH), present in pork liver, catalyses the formation of zinc-protoporphyrin (ZnPP), a stable purple-red pigment found in Parma ham. Kinetics of ZnPP formation is especially slow. Thus, ...
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 ...
Consumer attitudes toward consumption of meat products containing offal and offal extracts
(MDPI, 2021-06-23)
The development of food products containing offal and offal extracts could be part of the solution to the upcoming demand for animal protein. This study aimed to determine Spanish consumers’ attitudes ...
Formation of Zn-protoporphyrin during the elaboration process of non-nitrified serrano dry-cured hams and its relationship with lipolysis
(Elsevier, 2021-12-03)
This study assessed the ZnPP content, heme content, salt content, and instrumental color in the biceps femoris and semimembranosus muscles during the elaboration of Serrano dry-cured ham manufactured ...
