Abstract

The invention relates to a liquid steamed bun leavening agent and a preparation process thereof, belongs to the technical field of steamed bun preparation processes, and mainly solves the technical problems that the existing steamed bun leavening agent preparation process is greatly influenced by environmental factors and personal experience, the product quality is unstable and the like. According to the technical scheme, the liquid steamed bun leavening agent is prepared from the following raw materials in parts by weight: 15-25 parts of flour, 62-78 parts of purified water, 2 parts of cane sugar and 5-10 parts of zymophyte. The zymophyte is traditional old fertilizer. The preparation process of the liquid steamed bun leavening agent comprises the following steps: 1) sterilizing; (2) inoculating and fermenting; and (3) sub-packaging for later use. The method has the advantages that the product quality is stable, the taste is good, health factors and prebiotics are synthesized, the production efficiency is high, and the method is suitable for general popularization and use.

Description

technical field [0001] The invention belongs to the technical field of steamed bread production technology, and in particular relates to a liquid steamed bread starter and a production process thereof. Background technique [0002] Mantou is a traditional staple food in my country, especially in the north, with a history of more than 1,700 years. Among them, traditional fermented old noodles (also known as sour dough) have played an irreplaceable role as an indispensable raw material for making steamed bread. [0003] However, with the development of biotechnology, instant dry yeast has gradually replaced the status of old noodles due to its advantages of easy industrial production, stable quality, and rapid fermentation, and has become the preferred starter for daily steamed buns. However, today , People are no longer just satisfied with filling their stomachs, and pay more attention to the taste, flavor and nutritional characteristics of food. Because it is only fermented...
