Description

This document contains the experimental data generated during the preparation of the manuscript "Brazilin-Loaded Biodegradable Electrospun Membranes with Tunable Release for Active and Intelligent Food Packaging". This study reports the fabrication and characterization of electrospun poly(lactic acid) (PLA) and poly(ethylene glycol) (PEG) membranes incorporating brazilin, a natural polyphenolic compound with antioxidant, antimicrobial, and pH-responsive dye properties. Monoaxial and coaxial electrospinning were employed to tailor fiber morphology and release kinetics, enabling modulation from rapid to sustained diffusion. The dataset documents the analysis of the fibers via SEM and fluorescent microscopy, the analysis of the swelling and release behaviour of the fibers, the antioxidant activity (ABTS and FRAP), the antibacterial behavior, as well as the colourimetric response to changes in pH. Collectively, these findings establish brazilin-loaded electrospun membranes as multifunctional, biodegradable packaging materials that integrate active protection with intelligent sensing. By uniting sustained antioxidant activity, targeted antimicrobial efficacy, and visible spoilage indication, this work advances the development of next-generation packaging technologies that enhance food quality, safety, and sustainability.
