This week we bring you application notes by Agilent Technologies, KNAUER and Shimadzu, brochure by Thermo Fisher Scientific and poster by Waters Corporation!

Hexane remains a key food extraction solvent, but EFSA now calls for re-evaluation of its long-term safety. Robust GC-FID and GC-MS methods are critical for reliable residue detection and risk assessment.

This study uses GC×GC–qMS to characterize volatile organic compounds in commercial poi, revealing clear differences between fresh and aged products and distinct brand-specific profiles.

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.

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.

MOSH/MOAH testing is becoming a key topic in food safety and regulation. Discover how Thermo Fisher Scientific’s LC-GC-FID and GC×GC-MS workflows improve reliability, compliance, and source identification.

The study evaluates GC injection techniques to minimize artifact formation in odorant analysis, confirming on-column injection as most accurate and recommending its use in GC–olfactometry.
