Quality Protection of Patato Chips by Packaging with GL-E Film

Abstract

The applicability of GL-E film with vapor-deposited SiO_x to replace existing aluminium metalized film as a food packaging material was investigated. Commercial potato chips packed in clear, white-or silver-printed GL-E and aluminium metalized films were stored for 4 weeks at room temperature under fluorescent lights. The peroxide value (POV) and TBA value of the oil extracted from the stored potato chips were measured, and their flavor was examined by a sensory test and color check. The POV and TBA values of extracts from potato chips packed with either the clear or white-printed GL-E film increased, and their flavor deteriorated. The quality of potato chips packed with the silver-printed GL-E film retained as good condition as that with aluminium metalized packaging.
