While no previous study has investigated factors affecting
morphology of popped flakes, several studies have investigated
factors influencing other end quality measures for popcorn,
particularly expansion volume and unpopped kernels. These
studies reveal that microwave popping of popcorn is a complicated
system that is dependent on a variety of both intrinsic factors
including hybrid and extrinsic variables including microwave
wattage and oil added . This suggests that
formation of popcorn flake polymorphisms is influenced by many
of the same critical factors which have been established for
affecting popcorn expansion volume and unpopped kernels.
