Abstract
The packaging materials polyethylene (PE), Glass (G) and polyethylene terephthalate (PET) are considered the most commonly used in packing edible oil in Egypt. So, the current investigation aimed to study the Changes that occurred in physicochemical properties, fatty acid composition, Atherogenicity index (AI) factor, C18:2/ C18:3 , total saturated fatty acids/total unsaturated fatty acids (TSFA/TUFA )ratios and oxidative stability (OS) of refined sunflower oil (RSO) as a result of its storage at room temperature for 6 months in three different types of packaging materials (PE, G and PET).The OS (induction period, IP) of stored RSO were estimated using Rancimat at three different temperatures being 90,100 and 110° C. The obtained data of these tests were used in estimating the thermo dynamic properties such as Activation energy (Ea), Arrhenius factor (Arrh.Factor), activation enthalpies (ΔH) and entropies (ΔS). As well as the Shelf-lives (predication index IP25) of investigated oil samples have been also predicted. The results showed that OS of RSO stored in different packaging materials was in the order; control G > PET > PE.
