Resumo

The objective of this work was to develop gelatin based films using hydrophobic plasticizers: tributyl citrate or o-acetyltributyl citrate. A surface response methodology was used to evaluate the effect of the gelatin concentration, plasticizer concentration, lecithin concentration and plasticizer type on mechanical properties, solubility in water and water vapor permeability of films. The films were produced by casting technique. In general, the properties of the films based on gelatin and hydrophobic plasticizers were affected by plasticizers type and concentration. (AU)
