Abstract: | The iron-free heme derivative protoporphyrin-IX, was added to a cooked emulsified beef product to mimic the typical cured-color obtained with nitrite. Although the pigment was stable and could be recovered from the emulsion it imparted a purple hue as noted by visual observation and Hunterlab color values (L,a,b). The possible implications of this pigment as a meat colorant are discussed. |
