Integrative Metabolomic and Transcriptomic Profiling Reveals the Chemical and Molecular Basis for Aroma Divergence in Isatis Fruits

open access: yesFood Frontiers, Volume 7, Issue 3, May 2026.
Integrative metabolomic and transcriptomic analyses revealed the chemical and molecular basis of aroma divergence in fruits of three Isatis species. Distinct volatile profiles and 44 key aroma‐active compounds defined species‐specific sensory characteristics, while co‐expression analysis identified NAC transcription factors and lipid‐derived pathway ...

Advances in Wine Yeast Autolysis: Biochemical and Molecular Mechanisms, and the Release of Organic Compounds in White and Sparkling Wines—An Updated Review

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 3, May 2026.
ABSTRACT Wine yeasts play a central role in alcoholic fermentation and significantly contribute to the sensory attributes of wines through cellular autolysis during lees aging (sur lie), especially in white wines. This process releases organic compounds that alter the wine's chemical and sensory profile.

Electrospun Fibers for Solid-Phase Microextraction

open access: yesAnalytical Chemistry, 2010
A method of producing solid-phase microextraction (SPME) fibers based on electrospinning polymers into nanofibrous mats is demonstrated. Using this method the polymer mat is attached to a stainless steel wire without the need of a binder. While applicable to any polymer that can be electrospun, a polymeric negative photoresist, SU-8 2100, is used for ...
