Torula yeast can be grown on wood sugars obtained as a byproduct of paper production, as well as other sources of sugar. It is inactivated and then used as a flavoring or taste enhancer, thanks to its monosodium glutamate (MSG) content and umami taste. People who believe they are sensitive to MSG might try to avoid foods containing Torula, but there have not been any studies testing Torula for MSG-type reactions. On food labels, Torula yeast may be listed by name or hidden under the term "natural flavorings."
When Germany experienced food shortages in World War I, Torula yeast was used as a protein-rich food source.
