Application


  • Gradually supply of isoamyl alcohol increases the isoamyl acetate production in solid-state fermentation.: This study demonstrates how controlled addition of Isoamyl alcohol enhances isoamyl acetate production in solid-state fermentation, suggesting applications in industrial biotechnology for flavor enhancement (Sainz-Mellado et al., 2023 link).

  • Key aroma compounds and metabolic profiling of Debaryomyces hansenii L1-1-fermented Flos Sophorae.: Investigation into the metabolic pathways in Debaryomyces hansenii fermentation, where Isoamyl alcohol serves as a crucial intermediate, contributing to the unique aroma profile of the fermented product (Zhang et al., 2021 link).
