Olive Oil Quality Analysis and the Detection of Adulterations by GC‐MS With Cold EI

Journal of Mass Spectrometry, Volume 61, Issue 9, September 2026.
ABSTRACT Olive oil is widely consumed for its nutritional and health benefits, yet its high market value makes it vulnerable to adulteration and mislabeling. Current analytical approaches for assessing olive oil quality and authenticity rely largely on indirect analyses, such as fatty acid methyl ester (FAME) profiles, peroxide values, or UV absorbance,

Smart detection of juice adulteration: An approach based on ion mobility spectrometry and machine learning

Journal of the Science of Food and Agriculture, Volume 106, Issue 12, Page 7406-7415, September 2026.
Abstract BACKGROUND Fruit juice quality is regulated by European Union legislation; however, adulteration by adding cheaper alternatives, such as white grape juice, remains a prevalent issue. This practice constitutes economic fraud and poses health risks to consumers, including potential allergic reactions to the adulterant.

Species Determination Within the Felidae Family Using mtDNA Minibarcoding

Animal Genetics, Volume 57, Issue 4, August 2026.
ABSTRACT Wildlife forensic analysis frequently deals with highly degraded DNA samples, including those from tanned hides, processed products of traditional Chinese medicine, and specimens stored in preservation fluids. These samples present significant challenges for traditional DNA barcoding due to the difficulty of amplifying sufficiently long DNA ...

Investigations Into the Metabolism and Elimination of Flmodafinil and Fladrafinil for Sports Drug Testing Purposes

Drug Testing and Analysis, Volume 18, Issue 8, Page 1076-1087, August 2026.
This article investigates the metabolism and elimination of flmodafinil and fladrafinil, two fluorinated analogs of modafinil and adrafinil listed as S6 stimulants by the World Anti‐Doping Agency. After single‐dose administration to six volunteers, the compounds and their main metabolites were studied in urine and blood.

Identification of Synthetic Urine by Analysis of Stable Carbon and Nitrogen Isotope Ratios and Comparison to Established GC‐MS/MS and LC‐MS/MS Analysis

Drug Testing and Analysis, Volume 18, Issue 8, Page 1145-1151, August 2026.
This study compared GC‐MS/MS, EA‐IRMS, and LC‐MS/MS for detecting synthetic and manipulated urine samples in doping control and forensic analysis. EA‐IRMS proved particularly effective for identifying mixtures of synthetic and authentic urine, providing a reliable complement to established authenticity testing methods.
