Aroma and Metabolic Profiling of Hass Avocado via HS-SPME-GC-MS
July 15th 2025Researchers at the University of Caldas (Manizales, Caldas, Columbia) investigated the volatile organic compounds comprising the volatilome of Hass avocado peel, pulp, and seed grown in the northern Caldas (as well as avocados purchased from commercial sources), employing headspace solid-phase microextraction (HS-SPME) coupled with gas chromatography-mass spectrometry (GC–MS) for their extraction and identification.
Mass Spectrometry Fingerprinting and Neural Networks for Coffee Sensory Profiling
July 14th 2025Researchers from the University of Campinas (Campinas, Brazil) and the Waters Research Center (Budapest, Hungary) introduced a rapid, automated method using laser-assisted rapid evaporative ionization mass spectrometry (LA-REIMS) with high-resolution mass spectrometry to fingerprint coffee samples and predict sensory properties. LCGC International spoke to Leandro Wang Hantao of the University of Campinas regarding their work and the paper that resulted from it.
