What causes the pink color of cured meat?
When nitrosomyglobin is exposed to heat, nitrosohemochrome is formed. Nitrosohemochrome is the pink color, typical of cured meats. The stability of the nitrosohemochrome pigment is influenced by oxygen, light and the percent of total myoglobin pigment that is converted to nitrosohemochrome.
Why does vacuum sealed meat have a dark color?
Vacuum packaged fresh meat has a dark, purplish red color because the oxygen has been removed from the package and reducing enzymes have converted the meat pigment back to myoglobin. Once the meat is taken out of the vacuum package it will recover its bright red color, albeit for a shorter time period than its unvacuum packaged counterpart.
