Park, Jong-Beom published the artcileDevelopment of Korean Indigenous Low-Temperature-Tolerant Yeast for Enhancing the Flavor of Yakju, Product Details of C4H10OS, the main research area is Saccharomyces temperature flavor yakju Korea.
Yakju, a traditional fermented beverage in Korea, is prepared using various raw materials and methods, and, hence, exhibits various characteristics. Low-temperature-fermented yakju can inhibit the growth of undesirable bacteria and is known for its unique flavor and refreshing taste. To increase the production of volatile aromatic compounds in yakju, strains with strong resistance to low temperatures and excellent production of volatile aromatic compounds were screened from indigenous fruits (grape, persimmon, plum, aronia, wild grape) and nuruk in Korea. One Saccharomyces cerevisiae and three non-Saccharomyces strains were finally screened, and yakju was fermented at 15°C through mono/co-culture. The anal. of volatile aromatic compounds showed that S. cerevisiae W153 produced 1.5 times more isoamyl alc. than the control strain and reduced the production of 2,3-butanediol by a third. Similarly, a single culture of Pichia kudriavzevii N373 also produced 237.7 mg/L of Et acetate, whereas Hanseniaspora vineae G818 produced ∼11 times greater levels of 2-phenethyl acetate than the control. Alternatively, Wickerhamomyces anomalus A159 produced 95.88 mg/L of Et hexadecanoate. During principal component anal., we also observed that the co-culture sample exhibited characteristics of both volatile aroma compounds of the single cultured sample of each strain. Our results suggest that yakju with unique properties can be prepared using various non-Saccharomyces strains.
