Evaluating Stabilizers Effects on Aroma Release Dynamics in Ice Cream: A PTR‐ToF‐MS Analysis
Journal of Mass Spectrometry, Volume 61, Issue 8, August 2026.ABSTRACT Capturing the dynamic volatilome of frozen matrices during phase transitions remains an analytical challenge, typically requiring invasive sampling. This study employs proton transfer reaction time‐of‐flight mass spectrometry (PTR‐ToF‐MS) as a rapid, noninvasive technique that directly samples headspace volatiles without preconcentration to ...

Effect of carcass storage condition on searcher efficiency trials for conservation detection dogs
The Journal of Wildlife Management, Volume 90, Issue 6, August 2026.We investigated the influence of storage condition on bat carcass odor through chemical analysis. Additionally, we tested the detectability of 3 carcass storage conditions through searcher efficiency trials with conservation detection dogs. Only 20% of the chemicals observed were shared across all 4 carcass storage conditions.
