Chemometric GC×GC–MS analysis revealed that Brazilian hop cultivars are chemically similar to imported hops of the same type, with differences in selected terpenes relevant to brewing quality.

A novel persistence-directed testing approach combined with nontarget GC-MS and LC-HRMS revealed a significant fraction of persistent chemicals in offshore oil platform produced waters.

Day 1 in České Budějovice featured an Orbitrap plenary by Alexander Makarov, sessions on exposome, proteomics and structural MS, sponsor talks, flash talks and an evening networking reception.

Aroma analysis of six CBD hemp cultivars revealed 52 odor-active compounds, many new to hemp. Key terpenes and potent sulfur odorants drive distinct scent profiles across varieties.

Molecular sensory analysis confirmed that wood smoke during cocoa drying causes smoky off-flavors. Major odorants were found in both nibs and husks, showing limited removal during processing.

Suspect screening using LC- and GC-HRMS identified 547 chemicals across environmental, food, and human samples. Pharmaceuticals, pesticides, and personal care products were the most frequent contaminants.

Essential oil from Aiouea dubia leaves was analyzed by GC–MS/FID and enantioselective GC. Major terpenes and chiral profiles suggest antibacterial and anti-inflammatory potential for cosmeceutical use.
