Abstract The effect of using four plasticizers namely ethylene glycol, propylene glycol, glycerol and sorbitol on mechanical and water barrier properties of transglutaminase cross-linked zein–oleic acid composite films was investigated. Results revealed that both mechanical and water barrier properties of the films were significantly affected (p<0.05) by plasticizer type. Tensile strength (TS), water vapour permeability (WVP) and solubility (SB) values were all better in ethylene glycol control plasticized films compared to other plasticizers. Furthermore, irrespective of plasticizer type, transglutaminase treatment improved TS while when oleic acid was incorporated into the films in the range of 1–4% based on zein weight, the mechanical and water barrier properties of the composite film were diversely affected. Results from scanning electron microscopy for the 2% oleic acid-incorporated composite films revealed a rough and irregular surface morphology for the sorbitol plasticized films. Overall, ethylene glycol provided better mechanical and water barrier properties.

Abstract The effect of gallic acid treatment on mechanical and water barrier properties in zein and zein–corn starch composite films was investigated. Four concentrations of corn starch (5 %, 10 %, 15 %, 20 %) were used in composite films making a final solid concentration of 6 % (w/v) in the film forming solution. One composite film containing 10 % corn starch was also prepared in absence of gallic acid for comparison purpose. Gallic acid treatment improved tensile strength (TS) and water vapor permeability (WVP) while solubility was increased in control zein films. On the other hand, gallic acid treatment significantly (p < 0.05) reduced TS and increased WVP in zein–corn starch composite films. Interestingly, mechanical and water barrier properties of composite films prepared in absence of gallic acid were comparatively better than gallic acid treated composite films. These findings provided useful insights in how each individual hydrocolloid in the composite film was differently affected by gallic acid treatment.

In the paper, preparation and properties of pullulan composite films were studied. Several kinds of materials (glass, iron, steel, propene polymer and polyvinyl chloride plates) were chosen for preparing films. The results showed that the steel plate was the most suitable material for preparing film. The tensile strength of pullulan film was significantly reduced when the drying temperature was higher than 50°C. The time of dissolution observably decreased, whereas water vapor permeability increased with increasing drying temperature. Pullulan film has higher tensile strength, better water barrier properties, shorter solubilization time and lower elongation at break than those of hydroxypropylmethylcellulose film, respectively. The composite film (Pullulan and hydroxypropylmethylcellulose) with weight ratio (1/2) has higher tensile strength, better water barrier properties, longer solubilization time than those of other ratios. Difference properties of films could be obtained in different weight ratio (Pullulan and hydroxypropylmethylcellulose).
