Özet
The valorization of agricultural waste through nanoemulsion technology has emerged as a sustainable strategy for developing functional colloidal delivery systems. In the present study, a nanocellulose-stabilized nanoemulsion encapsulating guar straw extract was developed and optimized, with formulation NGS9 demonstrating superior physicochemical stability. The NGS9 sample exhibited a low creaming index of 0.36 and 5.12 at 0 and 30 days, respectively, during storage days, indicating strong resistance to gravitational separation. The combined stabilizing action of nanocellulose, pectin, Tween 80, and lecithin provided efective steric and interfacial stabilization, minimizing droplet coalescence and gravitational separation. Droplet size analysis confrmed the nanoemulsion’s nanoscale size at 166.26 ± 4.39 nm, whereas the zeta potential (-13.21 ± 0.36 mV) indicated that steric stabilization predominantly governed the system’s stability. Fourier transform infrared analysis determined the functional groups present in the emulsion sample, and scanning electron microscopy micrographs revealed spherical, uniformly dispersed droplets with minimal aggregation. Overall, the optimized nanoemulsion (NGS9) demonstrated high physicochemical stability and structural integrity, and it represented a promising biopolymer-based nanoemulsion platform for the encapsulation and stabilization of hydrophobic bioactive compounds derived from agricultural residues. Future studies should focus on evaluating the incorporation of this nanocellulose-based nanoemulsion into real food matrices and on investigating its bioactive delivery efciency, storage stability, and functional performance in food, nutraceutical, and other bioactive product applications.
