“…In the present study, the highest results of Rancimat induction period (IP) values calculated accounted for almost 2 h for roasted hazelnuts (Table 2.). In the majority of papers on oxidative stability, Rancimat analyses are performed at 110 or 120°C (Hassanien et al 2014;Gharby et al 2011); however, the Rancimat results are repetitive even at 140°C (Mateos et al 2006). IP values obtained in 140°C for olive oils were in the range of 0.9 to 9.8 h (Mateos et al 2006), and the results obtained herein for hazelnut oils were within the range presented for olive oil.…”

“…Determining oxidative stability is a tedious and timeconsuming method when analysed at room temperature (Mateos et al 2006), but even if accelerated methods like Rancimat are applied, the time of one analysis can last long. In the present study, to get a complete picture of the oxidative stability of oil cold pressed from roasted hazelnuts, PDSC measurements were conducted.…”

“…The determination of oxidation stability is a time-consuming process when the analysis is performed at room temperature. Therefore, the Rancimat method is typically used as an accelerating method to determine the oxidation stability in a shorter period of time 33 . Rancimat method is based on the production of volatile degradation products, assayed by the changes observed in the electrical conductivity of distilled water.…”

“…Ces résul-tats sont en accord avec ceux des études sur quelques varié-tés de l'huile d'olive (Abaza et al, 2005 ;Ben Temime et al, 2008a). D'autres auteurs ont également trouvé un temps d'induction faible de la variété Arbequine par rapport à d'autres variétés étudiées (Ceballosa et al, 2003 ;Gutiérrez et al, 2002a ;Mateos et al, 2006). La stabilité oxydative faible marquée chez « Arbequine » a été bien corrigée par assemblage : elle a augmenté de 13 h jusqu'à 23 h. Une nette corrélation négative entre la stabilité oxydative et la teneur en acides gras polyinsaturés a été signalée (Fig.…”
