Abstract

Wuchang Daohuaxiang (DHX) rice is a famous product in China, while identification and authentication method is limited. Due to the special taste and flavor of DHX, lipidomics was conducted to discriminate it from faked rice. First, lipid profiles of DHX and other nine rice varieties were required from the established UPLC-Q/TOF-MS/MS method. The compositions and contents of lipids significantly varied among different rice. Then, twenty-six potential biomarkers containing 6 DGs, 5 PAs, 4 PCs, 1 PE, 3 PGs, 2 PIs, 2 PSs, 2 SMs, and 1 Cer were characterized and verified for identifying DHX from all faked rice. The accuracy of developed methods for DHX discrimination was 97.14%. In addition, OPLS-DA models were established for DHX distinction between each of the nine rice cultivars. Our results would supply as supplementary tools for discrimination of DHX rice for supervision departments and industries.
