Research Abstract

Acetone (75%) was found to be the most effective organic solvent for extracting red pigment from Parma ham. Visible spectra of acetone extract from Parma ham showed absorption maxima at 417,546 and 584 nm. The red pigment could not be completely extracted with water about 10% remaining in the ham. Several experiments on pigment stability indicated the red pigment to be much more stable than nitrosylheme pigment present in cured ham. Structural characterization by thin-layr chromatography, infra-red spectral analysis and electron spin resonance technique showed the red pigment to be a new myoglobin derivative, hitherto unknown in meat or meat products.
Staphylococci isolated from Parma ham generated red myoglobin derivative from metmyoglobin. Model fermented sausage prepared by inoculation with the isolates developed a more desirablered color without nitrite or nitrate treatment. The red pigment of Parma ham and the model sausage appeared to be the same myoglobin derivative. The reddening of Parma ham is probably caused by the action of bacteria.
