Study of mechanisms for vapor-induced puffing of starch-rich materials
Solids puff when unbalanced forces exerted by vapor and gas in pores exceed the yield strength of solid surrounding the pores. Pressures increase as temperature rise; and matrix yield strength and flow resistance decrease. Expansion triggered by losses of matrix strength due to melting and glass-rub...
