| Summary: | In order to secure domestic microbial resources, a fruit-flavored yeast was selected, and a starter manufacturing technology was developed to evaluate its quality characteristics. Among 26 yeast strains analyzed using an electronic nose, <i>Saccharomyces cerevisiae</i> YM45 isolated from <i>Makgeolli</i> was identified as having high levels of methyl formate and propan-2-one, compounds that are associated with fruity and sweet aroma. A powdered starter was then produced with <i>S. cerevisiae</i> YM45, and its quality characteristics were analyzed. When cyclodextrin was used as an excipient, with water content at 4.7%, bacterial contamination was found to be 2.30 log CFU/g, which ensures quality and safety. The rehydration rate, assessed using a PBS buffer, showed a high survival rate of 8.7 log CFU/g, which is a suitable condition for preserving yeast activity. These findings suggest that domestically sourced microbial resources can serve as viable alternatives to imported strains, with potential applications in industrial fermentation. |
