The invention relates to a quickly frozen steamed bun raw product and a production method thereof, belonging to the technical field of food processing. Wheat flour, Yanshan yeast, aluminum-free baking powder, white granulated sugar, shortening, salt, transglutaminase, lipase, xylanase, glucose oxidase, trehalose, ascorbic acid, lecithin, sugar ester, glycerol, locust bean gum, artemisia gum, carboxymethylcellulose, guar gum, wheat gluten, wheat starch, or corn starch, or potato starch or rice starch are put in a mixing tank, are slowly agitated and are evenly mixed, water is added in the mixture and the obtained mixture is agitated into dough at medium-speed; the dough is pressed and formed, the obtained dough is quickly frozen after the bough is pre-fermented and cooled or the obtained dough is directly and quickly frozen, and the obtained dough is frozen for future use; and when in use, the dough is directly steamed only to obtain fresh bun products, and for dough not pre-fermented,pre-fermentation is required before steaming. The invention has the advantages that the traditional manual workshop production of the steamed bun is shifted to industrial production in an accelerating way, the product quality, the safety and the convenience are improved, the flavor loss caused by repetitive steaming is avoided and the energy is saved when compared with the steamed bun products quickly frozen after steaming.
