    The color change is instantaneous so light exposure is not a factor.  Interested in knowing more about the reduction reaction.  When you say ‘free’ Vitamin A is formed from the reaction with Vitamin K then what forms - the ester of Vitamin A?  Also what happens to the Vitamin K - is it oxidized?
