Preserving the Authenticity of ST25 Rice (Oryza sativa) from the Mekong Delta: A Multivariate Geographical Characterization Approach

Abstract

The research centers around ST25, a recently acclaimed rice variety lauded as Vietnam’s premier offering. However, its ability to substantiate its origin is impeded by the rampant proliferation of counterfeit derivatives within the market. A distinctive methodology is posited herein, intertwining the attributes of Fourier Transform Infrared Spectroscopy (FTIR) and Inductively Coupled Plasma Mass Spectrometry (ICP-MS) analyses, augmented using Principal Component Analysis (PCA). The primary objective is to meticulously ascertain the unadulterated geographic provenance of the ST25 rice cultivar. The findings unequivocally underscore the emergence of a conspicuous taxonomy within the ST25 rice ..
