Pigmented landraces showcased superior nutritional and functional attributes, including higher total dietary fiber and starch content. Fourier\u2010transform infrared (FTIR) analysis revealed distinct molecular signatures with enhanced peak transmittance, while X\u2010ray diffraction (XRD) indicated greater crystallinity ranging from 36\u201344.3% in pigmented rice compared with 30\u201340% in non\u2010pigmented rice, suggesting improved digestibility and processing versatility. Pigmented rice recorded less amylose content hence tended to possess increased adhesiveness values whereas non\u2010pigmented rice revealed greater amylose content hence was coupled with greater hardness values. Field\u2010emission scanning electron microscopy (FE\u2010SEM) images revealed that pigmented rice had densely packed and polygonal starch granules whereas non\u2010pigmented rice had loosely packed starch granules with intergranular voids. Untargeted gas chromatography\u2013mass spectrometry (GC\u2013MS) profiling identified 84 metabolites, including unique compounds such as 3,3\u2010dimethylbutanol and ethanoic acid, along with shared metabolites such as sucrose and linoleic acid, highlighting notable biochemical diversity. Multivariate statistical analyses using principal component analysis (PCA) and partial least squares\u2010discriminant analysis (PLS\u2010DA) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway mapping further differentiated the metabolomic landscapes, with variable importance in the projection (VIP) scores identifying key bioactive contributors.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSION<\/jats:title>\n                    <jats:p>Pigmented rice landraces exhibited significant functional and nutritional advantages, making them promising candidates for functional food development and nutritional improvement programs.
