Abstract:
The presence of oxygen can degrade food quality, making it essential to remove oxygen from the packaging headspace of food products. In this study, the effect of catalyst type and concentration on iron-based oxygen-scavenging films was investigated to enhance the oxygen removal efficiency in food packaging films. Among the investigated catalysts, calcium chloride and lipophilic silica improved the oxygen-scavenging capacity more than sodium chloride and hydrophilic silica. As the catalyst content was increased from 0.1 to 6.0 %(w/w), the oxygen content (%) in the package decreased from 3.90 to 0.36%. Application of oxygen-scavenging films in apple packaging decreased the apple browning index from 52.87 to 38.13 and reduced the oxygen concentration inside the package from 9.8 to 0.0%. Therefore, the food packaging film developed in this study can be used as a food packaging material that removes oxygen and thus prevents food quality deterioration.
