Harper's Biochemistry 24 Ed. identifies certain amino acids (high in animal
products) that putrefy creating hydrogen sulphide - the "bad egg" smell
associated with rotting flesh. Some of that hydrogen sulphide becomes
sulphuric acid. Eating a lot of beans could also have a similar effect for
the same reasons.

I've read that very few carnivores, in fact I think only the crocodile and
maybe vulture, will eat putrefying meat, which may explain the claims made
by Audette. Most carnivores want very fresh meat, or even eat it live, and
are not attracted by the smell of rotting meat. This certainly applies to
felids, though personally I would gamble on this alleged effect even if I
ate meat.

A phlebotomist friend of mine recently confirmed that blood drawn from
"omnivores" can often be distinguished from vegans by its smell of
putrefaction.
