Myoglobin is one of the more heat-stable
of the sarcoplasmic protein, which is almost
completely denatured between 80 and 85°c
[20]. According to the authors [49] the
compound involved in increasing redness of
muscles should be globin hemochrome, in
which the iron is in the Fe2+ state. Its color is
typically dull red. Globin hemichrome, with
the iron in the Fe3+ state, is largely responsible
for the browngrey hue. The balance between
hemochromes and hemichromes is affected by
the state of meat before cooking and other
factors, including species, animal and maturity
and muscle type.
