Incorporation of nitrogen-doped carbon dots synthesized from pomelo peels into PVA as highly antioxidant and UV-blocking food packaging film

This dataset supports a study on the synthesis and application of
nitrogen-doped carbon dots (N-doped CDs) derived from the albedo of pomelo
peel waste via hydrothermal treatment at 200 °C for 12 hours. Urea was
added as a nitrogen source in varying amounts (0–2.0 g) to modify the
surface chemistry of CDs, influencing their optical, antioxidant, and
UV-blocking properties. The dataset includes raw and processed data on
particle size (TEM and DLS), UV–vis absorption, fluorescence emission
spectra, zeta potential, quantum yield measurements, UV-blocking
measurement, and antioxidant activity (DPPH assay). Mechanical, thermal,
and barrier properties of poly(vinyl alcohol) (PVA) films incorporating
different CD loadings are also provided. These data were used to evaluate
the multifunctional performance of the CDs-loaded PVA films as active
packaging materials. The dataset enables reproducibility and facilitates
further analysis of biomass-derived carbon dots for food packaging
applications.
