Comparative evaluation of low- and high-field 1H NMR for vegetable oil authentication: classification, quantification, and routine applicability

Year: 2025

Type: article

Abstract: of 0.98 and root mean square error of prediction (RMSEP) of 3.0 for oleic acid. HF-NMR also detected adulterants as low as 5.0 % v/v with RMSE of cross-validation (RMSE-CV) below 5.0 for all of them. This study delineates the trade-offs between analytical performance, accessibility, and cost-effectiveness of LF and HF-NMR. While HF-NMR remains the gold standard for compositional analysis, LF-NMR shows promise as a cost-effective screening tool.
