Title:
METHOD FOR PRODUCING YEAST CONTAINING RICH-TASTE-IMPARTING SUBSTANCE AND METHOD FOR PRODUCING YEAST EXTRACT CONTAINING RICH-TASTE-IMPARTING SUBSTANCE
Document Type and Number:
WIPO Patent Application WO/2020/115993
Kind Code:
A1
Abstract:
This method for producing yeast containing a rich-taste-imparting substance includes: a step for yeast proliferation, in which yeast is modified such that intracellular acetolactic acid synthase activity is reduced, and isoleucine- and valine-requiring yeast is cultured and proliferated on a medium containing isoleucine and valine; and a step for generating a rich-taste-imparting substance, in which when the isoleucine content in the medium is less than 0.2 mass%, valine is added to the medium to culture the yeast and to generate a rich-taste-imparting substance, wherein the rich-taste-imparting substance is γ-Glu-Abu and/or γ-Glu-Abu-Gly.
