摘要:
The method of producing bakers yeast involves producing yeast from a substrate composed of date syrup (Dips) diluted by molasses in sufficient quantity to lower the concentration of organic acids present in the date syrup that are toxic to yeast to safe levels, preferably a 1:1 mixture (w/w) of date syrup (Dips) and molasses. The substrate is inoculated with viable cells of Saccharomyces cerevisiae yeast and placed in a bioreactor or fermentation vessel. The yeast is produced by a fed-batch process to ensure continuous yeast production and prevent or minimize the production of alcohol by the yeast, additional increments of the substrate being added about hourly for the duration (about 12 hours) of the yeast propagation process. The process produces bakers yeast comparable in quality to yeast produced from a pure molasses substrate for such purposes as making bread, and in sufficient quantity to be practical for industrial production.
