The invention discloses a making method of raw frozen steamed buns. The making method comprises the following steps: a, uniformly mixing 500 parts by weight of flour and 5-8 parts by weight of
baking powder so as to obtain a mixture, and then putting the mixture into a dough batch; b, putting 5-8 parts by weight of
yeast, 6-10 parts by weight of an additive and 240-260 parts by weight of water into the dough batch, stirring the mixture, the
yeast, the additive and the water for 8-10 minutes at a
low speed, and then stirring the mixture, the
yeast, the additive and the water for 10-15 minutes at a high speed so as to obtain dough; c, taking out the dough from the dough batch, repeatedly rolling the dough by a high-speed noodle press so as to obtain a strip, then
cutting the strip into blocks, and putting the blocks in the environment of 30-40 DEG C for
fermentation for 20-30 minutes; and d, rapidly freezing the fermented blocks in environment under minus 60 DEG C for 15-20 minutes, and then putting the blocks under the condition of the temperature of sub-zero 20 to sub-zero 15 for
frozen storage, namely completing the making operation of the raw frozen steamed buns. Compared with the prior art, the making method of the raw frozen steamed buns, disclosed by the invention has the advantages that rapidly freezing the blocks in the environment under minus 60 DEG C can completely reserve the
nutrition in the blocks, the raw frozen steamed buns can be eaten after being steamed once, and the
flavor, the color and the mouth feel of the steamed raw frozen steamed buns can be compared favorably with those of the fresh steamed buns.
