The application discloses a strain of
Rhodotorula mucilaginosa and application of the strain in cider
fermentation, and belongs to the technical field of microbial
fermentation. The
Rhodotorula mucilaginosa CXY1113 is obtained by separation from natural
fermentation cider, the strain can tolerate low-pH acidic environment, can utilize
malic acid as a
carbon source, and reduce the content of
malic acid. Compared with single fermentation of
Saccharomyces cerevisiae, the application of the
Rhodotorula mucilaginosa CXY1113 in cider production can improve the brightness of
fruit wine, enhance the
antioxidant activity, reduce the content of
malic acid,
acetic acid and
succinic acid in the cider, improve the content of
flavor compounds such as
ethyl phenylacetate and
isoamyl alcohol, the obtained cider has rich and mellow
aroma, high quality, coordinated taste, and gives the cider more mellow floral and fruity
aroma. The application has important significance for improving the taste and
flavor of
fruit wine and improving the quality of
fruit wine.
