The invention relates to the technical field of
food processing, and discloses a steamed bun making method which comprises the following steps: providing leavening dough, and fermenting under specific temperature and
humidity conditions to obtain leavening dough; mixing the leavening dough with
wheat flour and ingredients, and blending into dough; fermenting the dough under a specific temperature and
humidity condition until the dough is expanded to a specified multiple; the fermented dough is
cut into small dough, and the small dough is fermented after being formed; and
steaming the fermented dough, and cooling to obtain the finished steamed bun. The preparation method of the sour dough comprises the following steps: selecting
wheat flour and water in a weight ratio of (1: 3)-(1: 5), and mixing and stirring the
wheat flour and the water into paste; and adding active dry
yeast and white granulated
sugar, and uniformly stirring. By adding the ingredients, optimizing the making process and adjusting the proportion of the ingredients, the
hardness of the steamed buns is controlled to be 1000-1200 g, the elasticity reaches 0.8-0.95, air holes are uniformly distributed, the
specific volume is 1.8-2.2 m l / g, and the requirements of high-quality steamed buns for softness,
lightness and rich levels are met.
