Packaging and storage conditions affect the quality of edible plant oils, including garden cress oil, with high content of unsaturated fatty acids, which are subjected to hydrolytic and oxidative deterioration during storage. Aim of this research was to investigate the effect of amber coloured glass (AGL) bottle and transparent polyethylene terephthalate (PET) bottle on storage stability of garden cress seed oil (GCO). The bottles were filled with GCO and stored at room and refrigerated condition. Peroxide value (PV), acid value (AV) and iodine value (IV) of oil were analyzed for every 30 day for 90 days. Results revealed the storage period had significant effect of stability of GCO. Storage temperature affected the stability of oil more than the packaging material. Lowest PV, AV and highest IV was observed for AGL bottle at every stage during the storage whereas highest PV, AV and lowest IV was observed for oil stored in PET bottle at room temperature
