Modulating oxidative stability of zein-stabilized Pickering emulsions via interfacial nanoparticle localization and dual-phase antioxidant synergism: a real-time kinetic assessment by isothermal calorimetry.

ABSTRACT: This study explores the oxidative stability of zein-derived based Pickering emulsions, focusing on the synergistic effects of interfacial particle concentration and phase-specific antioxidant delivery. Emulsions were prepared with varying ZNP concentrations (0.5-2.0%, w/v) in combination with xanthan gum as a co-stabilizer, to which l-ascorbic acid in aqueous phase and α-tocopherol in oil phase were added, individually or in combination. Emulsions with 0.5-1.0% ZNP remained physically stable during 10 days at 40 °C, while increasing ZNP to 2.0% significantly reduced droplet size (22.3 ± 0.55 μm to 16.1 ± 0.38 μm) and enhanced oxidative stability, increasing induction time from 4.07 ± 0.10 × 10⁵ s to 5.15 ± 0.12 × 10⁵ s. Antioxidants further improved the
