A novel comprehensive two-dimensional gas chromatography coupled with mass spectrometry (GC×GC-MS) method has been developed to simultaneously quantify and identify a vast array of sugar compounds in human urine and serum. Utilizing a nonpolar-medium polar column setup, this advanced analytical approach overcomes previous limitations that restricted the simultaneous evaluation of complex sugar profiles to just a few compounds. The validated method successfully achieved absolute quantification for dozens of sugars—including discovering concentrations of several sugars in healthy adults for the very first time—demonstrating its significant potential for advancing future research in human nutrition, health biomarkers, and metabolic pathways.

Japanese researchers have developed an accelerated testing method to quickly and accurately determine if harmful chemicals leak from plastic packaging into food. Because real-time testing for long-shelf-life foods takes too much time, the team used liquid chromatography-tandem mass spectrometry (LC-MS/MS) to accelerate the process. By testing sample plastics in various food-simulating liquids, they proved the LC-MS/MS method is reliable.

Researchers utilized untargeted reverse-phase liquid chromatography-mass spectrometry (RPLC-MS) to analyze serum metabolite profiles under normal and sleep-restricted conditions. The RPLC-MS analysis successfully identified 90 circulating metabolites—including 14 of microbial origin—and demonstrated that sleep deprivation significantly disrupts the natural rhythmic cycles of these host and microbial compounds. These findings indicate that microbial metabolites detected via RPLC-MS could potentially serve as clinical biomarkers for the various health and metabolic risks associated with sleep loss.

Researchers evaluated the flavor quality of milk processed with alternating-current high electric field (AC-HEF) pasteurization compared to conventional ultrahigh temperature (UHT) treatment, which is known for producing undesirable "cooked" flavors. To analyze the differences, the team profiled volatile compounds using solid-phase microextraction gas chromatography-mass spectrometry (GC-MS) and utilized gas chromatography-sulfur chemiluminescence detection (GC-SCD) specifically for sulfur-containing volatiles. The robust chromatographic analysis revealed that AC-HEF effectively suppresses the formation of off-flavors while maintaining favorable aromatic compounds, suggesting it is a promising alternative for producing shelf-stable milk with an improved flavor profile.
