Abstract

Abstract: Vanillin‐loaded zein electrospun sub‐micron fibers were produced by electrospinning and intended for food packaging applications. The effect of the addition of different vanillin concentrations on the properties of zein nanostructured membranes and the relationship with fiber morphology was studied. Results indicated that vanillin was loaded in sub‐micrometric ribbon‐like fibers with random and isotropic orientation, whose size depended on the zein concentration. Vanillin migration tests were performed in different food simulants. This material shows potential application as active antimicrobial food packaging, e.g., in the form of patches inserted inside the primary packaging in direct contact with food like dried fruit and baked goods. Abstract : Through the electrospinning technique, a film was fabricated consisting of sub‐micrometric fibers of the biodegradable natural polymer zein and vanillin as an antimicrobial agent. The morphology of the obtained fibers, the encapsulation efficiency of vanillin in the zein fibers, and the migration tests in simulant fluids demonstrate the potential suitability of such films for active food packaging.
