As a means of achieving stability
To correct a problem
Different reactions will occur at different rates.
A steady state value may or may not be reached.
Faster at Higher Temperature
Slower at Higher Temperature
H2O2 + H3C-CH2
H3C-CH + 2H2O
Reaction of oxygen with anthocyanins leads to polymerization and stabilization of red color.
It’s what in there that counts!
