Pantothenic acid

Pantothenic acid is one of the B vitamins and a nutrient that plays an important role in yeast growth. It is involved in yeast metabolism and energy production, and the amount required can differ depending on the type of yeast. In sake brewing, for example, Kyokai No. 7 yeast may be identified by its pantothenic acid requirement, and this characteristic can be used in selecting and managing yeast strains. Because it also affects the quality and flavor of sake, it is an important factor for brewers.
