Tom,
Isn't there also a chemical reaction to the metal used in the cans that
can cause this same result?

RE: Blueing meat in pasteurized crab
Hello Danang,
What you call bluing may be related to the quality of the crabs before
cooking. There are several possible causes. A dull grayish color
sometimes indicates enzymatic degradation. What species are you
processing? All of the common causes of discoloration are quality issues,
not food safety. There are guidelines for proper use of SAPP but no known
toxic levels that I’m aware of. However, there should be no need to
exceed 1g SAPP per pound of crabmeat.
