Tracing the geographical origin of tiger nut (Cyperus esculentus L) in China based on stable isotopes and mineral elements combined with multi-modal recognition
{{output}}
The stable isotopes (δ13C, δ15N, δ2H, and δ18O) and elemental compositions, combined with chemometrics, were used to discriminate tiger nut from different producing regions in China. Statistics showed that there were significantly different in δ15N, δ2H,... ...
