Y297 Saccharomyces cerevisiae Y297 with adaptability at low temperature and manufacturing method of fermented alchoholic beverage using the same

摘要

The present invention relates to a new yeast Saccharomycescerevisiae Y297 deposited with the deposit number KACC93244P and a fermentation liquor produced using the same. Specifically, among 500 fermentation strains, growth is carried out at a low temperature of 15 ° C Y297 was selected as an excellent yeast, Saccharomyces cerevisiae. The strain was found to have excellent low-temperature tolerance and alcohol-producing ability, and the activity of glucosidase and esterase of Y297 yeast was compared with that of yeast It was confirmed that the quality of the fermented wine was 2 to 5 times better than that of the commercial yeast. As a result of confirming the quality characteristics of the fermented wine, the acidity was low, the alcohol content was high, the organic acid content was high and the free amino acid content was high. Y297 yeast can be used to produce high quality fermented beverage with excellent flavor, sweetness and aroma.
