Article Synopsis
  • Hineka is an off-flavor in sake caused mainly by dimethyl trisulfide (DMTS) and involves a precursor production pathway related to yeast metabolism.
  • The Km67 yeast strain, which is not a Kyokai strain, shows lower DMTS production due to its unique mechanism that affects S-adenosyl-methionine (SAM) levels during fermentation.
  • Research indicates that increased SAM accumulation enhances DMTS production, but the Km67 strain has a low SAM accumulation trait, which helps explain its low DMTS production in sake.

Dimethyl trisulfide (DMTS) is one of the main components responsible for hineka, the aroma associated with deteriorated Japanese sake during storage. The molecule 1,2-dihydroxy-5-(methylsulfinyl)pentan-3-one (DMTS-P1) has been previously identified as a major precursor compound of DMTS. Furthermore, it had been suggested that the yeast methionine salvage pathway is involved in the production of DMTS-P1.
