Abstract
To combat the fraudulent practice of adulterating Jiang-flavor Chinese spirits with edible alcohol, this study proposes the use of UPLC-Q-TOF/MS combined with metabolomics (ultra-performance liquid chromatography with time-of-flight high-resolution mass spectrometry) analysis to investigate the differential components between authentic Jiang-flavor Chinese spirits and those adulterated with edible alcohol. A total of 175 compounds were identified in both authentic and adulterated samples, of which 74 compounds showed significant differences (p < 0.01, fold change > 5), including acids, esters, aldehydes, ketones, alcohols, and heterocyclic compounds. OPLS-DA analysis revealed a clear distinction between authentic Jiang-flavor Chinese spirits and those adulterated with edible alcohol, with Q2 and R2Y values both above 0.9 and greater than 0.5, indicating that the model is stable and reliable for the identification of adulteration in Jiang-flavor Chinese spirits.
期刊介绍:
Food Analytical Methods publishes original articles, review articles, and notes on novel and/or state-of-the-art analytical methods or issues to be solved, as well as significant improvements or interesting applications to existing methods. These include analytical technology and methodology for food microbial contaminants, food chemistry and toxicology, food quality, food authenticity and food traceability. The journal covers fundamental and specific aspects of the development, optimization, and practical implementation in routine laboratories, and validation of food analytical methods for the monitoring of food safety and quality.
