In comparison to more traditional methods of determining food authenticity, such as gas chromatog. anal., the primary advantages of DART-HRMS include its high speed and throughput of anal. This study used a non-targeted metabolomics method based on real-time high-resolution mass spectrometry combined with chemometric anal. to distinguish lamb samples from four regions. Orthogonal least squares-discriminant anal. revealed a distinct difference between these four lamb regions. The potential markers were chosen based on the variables importance in projection values, variance, and fold change. A total of 79 markers were identified using the matching chem. database. These markers differed significantly between lambs in four regions according to heatmap anal. The linear discriminatory anal. model had an initial classification rate of 100.0% and a cross-validation accuracy of 82.50% on the identified markers. The research demonstrates that DART-HRMS can perform a rapid authentication evaluation of lamb samples. The experimental process involved the reaction of 2,3-Dihydroxypropanoic acid(cas: 473-81-4).Electric Literature of 473-81-4
