TL;DR
This study uses chemical and isotopic analysis to distinguish crab-field rice from conventional rice, helping prevent commercial fraud.
Contribution
The study introduces a novel combination of multi-element, stable isotope, and metabolite analysis with chemometrics for rice authenticity identification.
Findings
Seven elements, two stable isotopes, and nine metabolites were identified as key discriminators between crab-field and conventional rice.
Discriminant analysis models using elements/isotopes or metabolites can completely distinguish rice types.
The study provides effective methods for authenticating crab-field rice.
Abstract
The quality of rice is closely related to its planting mode. The rice produced in rice–crab co-cultivation fields often enjoy higher prices and consumption enthusiasm than traditional rice due to the use of fewer chemical inputs, making it a key target of commercial fraud. In this study, multi-element, stable isotope, metabolite analysis techniques were synergistically applied with chemometric methods to distinguish between crab-field rice and common rice. Seven elements (Se, Rb, Cu, Cd, Ag, V, and Zn), two stable isotopes (δ15N and δ13C), and nine metabolites were identified as the most important discriminant variables. The discriminant analysis model based on seven elements and two stable isotopes, or based on nine metabolites, can completely distinguish between crab-field rice and conventional rice. The isotope, elemental, and metabolic fingerprint spectra selected in this study…
