Interfacial Engineering of High-Performance Pickering Emulsion-Gelatin Composite Films for Active Packaging.

ABSTRACT: Amidst the urgent demand for sustainable alternatives to petrochemical plastics, this work incorporated oregano essential oil Pickering emulsion (AOPE; stabilizer: acetylated chitin nanocrystals (a-ChNCs)) into the gelatin matrix. Through precisely engineered hydrogen-bonding networks at the a-ChNCs/gelatin interface, achieved through the systematic optimization of AOPE concentration, a high-performance bio-based gelatin composite film (designated as GOP_X%) was developed. Low-field nuclear magnetic resonance analysis confirmed that GOP_X% containing AOPE exhibited increased hydrogen bonding crosslink density. At an AOPE loading of 6% (GOP_6%), the composite film exhibited exceptional improvements compared with GOP_0%: elongation at break increased b
