Resumen:
The effectiveness of 1,4butanediol diglycidyl ether (BDDGE) as a crosslinking agent of bovine gelatin films plasticized with Dsorbitol intended for food packaging is reported. Freestanding films were produced by casting gelatin filmforming solutions containing Dsoritol 30 % (g/100 g dry gelatin) and variable amounts of BDDGE (0?3 g/100 g dry gelatin). The addition of 1 % BDDGE (g/100 g dry gelatin) positively influenced the solubility, water vapor permeability, and mechanical properties of the produced films. Water solubility decreased about 77 %; the water vapor permeability enhanced 20 %, and the stretching ability increased 11 times while the tensile strength was reduced up to 7fold with regard to the noncrosslinked counterpart. A simple extraction procedure was applied to remove the potential unreacted BDDGE and its hydrolysis products from BDDGEtreated gelatin films. Quantification was performed by gas chromatography combined with mass spectrometry (GC/MS), being lower than 0.25 μg/kg (below the limit of detection, 0.30 μg/L). Results suggested that watersoluble BDDGE may provide an effective crosslinking alternative to the usual aldehydebased strategy to manufacture gelatin films with potential use as biodegradable food packaging materials
