This invention belongs to the field of microbial
fermentation and food flavoring technology, and discloses a specific
aroma-producing
yeast strain XQU7 and its applications. This strain is *
Hansenula polymorpha*. Hanseniaspora uvarum The strain, with accession number CCTCC M 2026992, produces a
fermentation broth containing various volatile substances including esters, alcohols, acids, aldehydes, terpenes, and
sulfur-containing compounds. It significantly enhances the content of characteristic
aroma components such as octanoic acid,
hexanoic acid,
benzaldehyde,
decanoic acid,
benzyl alcohol, and D-
limonene, resulting in complex flavors including fatty, fruity, sweet, ester, and fermented aromas, demonstrating excellent
aroma-producing properties. This strain can be used to prepare
fermentation flavor enhancers and aroma products, suitable for flavoring
processing in food, beverages, seasonings, Fu
brick tea, feed, and
pet food, with a wide range of applications and significant industrialization value.
