Although fat migration clearly contributes to bloom inhibition in
this case, the exact mechanismbehind this inhibition is still unknown.
Based on the soft texture of chocolate chips in cookies after baking,
we speculate that the phase behavior and change in crystallization/
polymorphism of the mixed fat system is responsible for bloominhibition. Perhaps the complex fat mixture in the chocolate chip after
baking does not undergo polymorphic transformations thought to be
responsible for bloom. Further work in the area is warranted
