摘要: The main objective of the present work was to determine whether a single agropolymer [wheat gluten (WG)] could fit modified atmosphere packaging (MAP) requirements range six different fresh produce in key terms oxygen permeation (PeO2) and CO2/O2 permselectivity (S) values. required properties for optimal fruits vegetables were first evaluated using Tailorpack MAP modelling software (UMR IATE, Montpellier, France) with dimensions respiratory data as input parameters. Then, modelled values obtained compared WG composite films: monolayer self-supported or multilayer at microscale nanoscale, cast thermoplasticised, formulations (percentage plasticisers nanofillers). experimental gas transfer that be covered by these materials ranged from 0.05 × 10−10 2.00 × 10−10 mol/m2 s Pa PeO2 up 18.0 S. These ranges are much larger than conventional plastics exhibit 0.10 × 10−10 0.20 × 10−10 mol/m2 s Pa S 4.5. It demonstrated food-requirements-driven (Tailorpack modelling) multiscale film structuring (WG-based composites) approaches, WG-based films would selected better plastics.
