The influence of packaging system on stability during storage of raw dried pistachio nuts was studied. The pistachio nuts were packed in plastic multilayer pouches (PS/EVOH/PE) at different conditions (atmosphere, vacuum and oxygen scavenger). Accelerated Shelf Life Testing (ASLT) method was used for evaluation the storage of pistachio at ۲۰, ۳۵ and ۵۰ °C. Samples were analyzed at ۴, ۸, ۱۲ weeks by using of split-plot design. To follow the oxidation profile, the formation of volatile oxidized products (Hexanal) was determined by GC-MS. Results showed that the formation of hexanal under all conditions was significant (p
