Development of a variety and quality evaluation method for Amomi fructus using GC, electronic tongue, and electronic nose.

is rich in volatile components and valuable as a medicine and edible spice. However, the quality of commercially available varies, and issues with mixed sources and adulteration by similar products are common. In addition, due to incomplete identification methods, rapid detection of the purchased quality is still an issue. In this study, we developed qualitative and quantitative evaluation models to assess the variety and quality of using GC, electronic tongue, and electronic nose to provide a rapid and accurate variety and quality evaluation method of . The models performed well; the qualitative authenticity model had an accuracy of 1.00 (n = 64), the accuracy of the qualitative origin model was 0.86 (n = 44), and the quantitative model was optimal on the sensory fusion data from the electronic tongue and electronic nose combined with borneol acetate content, with = 0.7944, RMSEF = 0.1050, and RMSEP = 0.1349. The electronic tongue and electronic nose combined with GC quickly and accurately evaluated the variety and quality of , and the introduction of multi-source information fusion technology improved the model prediction accuracy. This study provides a useful tool for quality evaluation of medicine and food.
