Food-grade compound-stabilized high-internal-phase Pickering emulsions (HIPEs) have received widespread attention in food industry and functional foods. However, challenges are still there regarding the inclusion of active substances and quickly processing molding for food manufacturing. Herein, we used zein, tannic acid (TA) and sodium alginate (SA) to synergistically increase the stability of HIPEs. Owing to electrostatic, hydrophobic and hydrogen-bond interactions among protein, polyphenol and polysaccharide, Zein-TA-SA composite particles-s...
