This study explored the physicochemical, technofunctional, antioxidant and in vitro antiglycaemic properties of\n                    <jats:italic>Telfairia occidentalis<\/jats:italic>\n                    leaf and seed powders, with emphasis on their application in low\u2010glycaemic food systems. The leaf powder (TLP) was characterised by high dietary fibre (9.42 \u00b1 0.56\u2009g\/100\u2009g) and polyphenol (TPC: 76.59 \u00b1 1.62\u2009mg\u2009GAE\/g; TFC: 44.58 \u00b1 0.77\u2009mg\u2009QE\/g), exhibiting strong antioxidant activity. In contrast, the seed powder (TSP) was rich in protein (29.52 \u00b1 0.34\u2009g\/100\u2009g) and lipids (19.71 \u00b1 0.73\u2009g\/100\u2009g), demonstrating superior oil\u2010holding, emulsifying and structural properties. Both fractions exhibited complementary antiglycaemic effects, including enzyme inhibition, glucose adsorption and reduced glucose diffusion, indicating multiple mechanisms of action.

Scanning electron micrographs and Fourier\u2010transform infrared (FTIR) spectra revealed distinct microstructural and molecular differences between TLP and TSP, highlighting a fibre\u2010rich porous matrix in the leaf and a protein\u2013lipid\u2010dominated structure in the seed. Functionally, TLP contributes fibre\u2010 and polyphenol\u2010mediated glucose regulation and antioxidant protection, whereas TSP provides protein\u2013lipid\u2010driven functional performance and modulation of glucose release and transport. These findings suggest that integrating TLP and TSP into composite formulations represents a promising strategy for developing low\u2010glycaemic, antioxidant\u2010rich foods with potential relevance for type 2 diabetes management.\n
