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

Food 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 ...

Integrative Insights Into Bioactive Peptides in Milk Fermented With Autochthonous and Commercial Cultures Using High‐Throughput Peptidomics and Machine Learning

Food Frontiers, Volume 7, Issue 3, May 2026.
This article highlights the crucial role of starter culture selection in shaping the peptide profile of fermented dairy drinks. Using high‐throughput peptidome profiling, the study demonstrates that different starter cultures yield distinct quantities and types of bioactive peptides, with excessive microbial combinations potentially reducing peptide ...

Volatilomic Differentiation of Protected‐Origin Italian Balsamic Vinegars by HS‐SPME‐GC×GC‐TOFMS

Journal of Separation Science, Volume 49, Issue 5, May 2026.
ABSTRACT Balsamic vinegars produced under Protected Designation of Origin (PDO) and Protected Geographical Indication (PGI) schemes differ substantially in raw materials, processing intensity, and aging regimes. Although these differences are expected to shape their volatile composition, a comprehensive chemical characterization capable of reliably ...
