Patent ID: 8323717

Claim:
A method of producing baker's yeast, comprising the steps of: preparing a substrate containing a 1:1 mixture (w/w) of date syrup and molasses, wherein the date syrup is extracted from Rezez dates and the molasses is produced from sugar cane; inoculating the substrate with Saccharomyces cerevisiae yeast; placing the inoculated substrate in a fermentation vessel; propagating the yeast under fermentation conditions, wherein propagation was a fed-batch process, at 30° C., 8 g/l inoculum size, 6.0 liter starting volume, and sugar concentration in the substrate was 200 g/l; periodically feeding additional substrate to the propagating yeast in quantities calculated to maintain yeast growth at a rate that avoids respirofermentative growth and formation of ethanol; and collecting viable yeast when propagation ceases.
