Although some studies on processes related to food steaming
have been reported, few studies on the modeling of food steaming
have appeared. The purpose of our study was to develop transport
models for the steam reheating of starchy food and to establish the
heat and mass transfer mechanisms of steaming. Because the interaction
of energy, water and vapor transport have been postulated
to be the dominant factors with respect to temperature changes
during steaming, we chose to focus our study on non-porous starch
gel radish cake and on porous-matrix steamed buns to minimize
the effects of other physical or chemical reactions without loss of
generality.
