ABSTRACT
The method of propyl gallate immobilization on the surface of polymeric film has been developed. Surface of polyethylene foil was modified by electric corona and coated with a chitosan layer prepared from 1% solution of polysaccharide dissolved in 1% lactic acid. Then, it was gelated in a mixture of ethanol and NaOH solution. A portion of gallate ranging from 2.87 to 5.67 μg/cm2 was immobilized in the coating prepared with the sorption method. The film obtained was characterised by antioxidant activity measured by scavenging DPPH• radicals and its mean value was equal to 9 x 10-3 TE/cm2. Preliminary measurements showed that the obtained polyethylene film coated with the chitosan layer containing immobilized propyl gallate lost half of its activity after about 5 months of storage at room temperature.
