PURPOSE:To adjust degree of expansion, hardness and degree of swelling when water is absorbed in it, by controlling difference of pressure between pressure in heating of raw material and pressure in popping. CONSTITUTION:The relationship between change of pressure difference between pressure in heating of raw material and pressure in popping and change of degree of expansion, hardness, degree of swelling when water is absorbed in popped food is taken into account. When the difference is large, the expansion of the popped food is large, and hardness is low, it has weak resistance to the teeth, and it has large swelling when water is absorbed in the popped food. USE:An instant food such as various rice cakes, various pilaf, having adjusted resistance to the teeth, to which hot water is poured.
