METHOD FOR PREPARING BREAD BY USING GRAIN SYRUP PRE-TREATMENT YEAST

摘要

PURPOSE: A method for preparing bread is provided to obtain high quality of bread by using Saccharomyces cerevisiae as one of common yeast to be treated into grain syrup state and adding the grain syrup yeast. CONSTITUTION: The method comprises treating the common yeast of Saccharomyces cerevisiae in a medium containing 2-5% MYP (consisting of 2-5% maltose, 0.5% yeast extract, 1% peptone, 0.3% KH2PO4) for 1.5-2.5 hours to preliminarily derive expression of a specified yeast gene concerning fermentation of the maltose; then adding the pre-treated yeast in the first kneading flour for baking the bread to ferment the kneading; alternatively forming a second kneading flour and adding it to the first kneading then secondly fermenting the kneading; and baking the kneading. The 2.5% MYP medium may be formed into the grain syrup state.
