Abstract

The invention discloses a method for preparing sourdough steamed bread by using saccharomyces cerevisiae and lactobacillus sanfranciscensis, and the method comprises the following steps: (1) respectively taking and mixing the bacterial sludge of the saccharomyces cerevisiae and the bacterial sludge of the lactobacillus sanfranciscensis with flour and water uniformly, and obtaining the sourdough after fermentation; and (2) uniformly mixing the sourdough with flour and sodium bicarbonate, and after conducting dough kneading, cutting, rolling, molding and recovering, conducting steaming to obtain the sourdough steamed bread finished product. The method for preparing the sourdough steamed bread selects the predominant lactobacillus strain lactobacillus sanfranciscensis and the predominant saccharomycetes strain saccharomyces cerevisiae in the traditional sourdough, adopts a lactobacillus-yeast mixed fermentation mode, effectively improves the mouthfeel, flavor and texture of the steamed bread, overcomes the defect of insufficient flavor of the sold products fermented by single yeast on the existing market, simultaneously improves the nutrient value of the steamed bread and prolongs the preservation time of the steamed bread.

Description

technical field [0001] The invention relates to the technical field of food fermentation, in particular to a method for preparing sourdough steamed bread by using Saccharomyces cerevisiae and Lactobacillus San Francisco. Background technique [0002] Mantou is a food made by mixing flour with yeast (old noodles), water, or edible alkali, kneading, proofing, and steaming. It tastes soft and delicious, and is rich in nutrition. It is a favorite in my country, especially in the north Traditional staple food. Among them, traditional fermented old noodles (also known as sour dough) have played an irreplaceable role as an indispensable raw material for making steamed buns. [0003] In the mid-1980s, instant active dry yeast was introduced into the Chinese market. With the invention of baker's yeast starter and the great convenience it brought, traditional pasta starter was gradually replaced. However, pure-bred baker's yeast is fermented with a single enzyme system, and the ferme...
