Sesame oil is an edible vegetable oil derived from sesame seeds.Besides being used as a cooking oil, it is used as a flavor enhancer in many cuisines, having a distinctive nutty aroma and taste. The oil is one of the earliest-known crop-based oils. Worldwide mass modern production is limited due to the inefficient manual harvesting process required to extract the oil.

Abstract. Oxidative stability of oils extracted from intact and dehulled sesame seeds was determined by monitoring changes in fatty acid composition, iodine value (IV), peroxide value (PV), conjugated diene (CD), para-anisidine value (p-AV), and 2-thiobarbituric acid (TBA) value and by nuclear magnetic resonance spectroscopy after storage under Schaal oven conditions at 65°C for up to 35 d.
Effect of processing on oxidative stability and lipid
Sesame oil and seed products are highly stable against oxidative processes. The effects of sesame seed pretreatment, including roasting (R), steaming (S), roasting plus steaming (RS) and microwaving (M) on crude oil quality from intact Egyptian and Sudanese seeds were investigated. Oxidative stability of seasame seeds was determined by
The sesame seed oil is more resistive to oxidation than nigella and cactus, but similar to that of olive and argan oils. A combination of several compounds is likely to be responsible for the good oxidative stability of sesame seed oil (Sabah El Khier et al., 2008, Lee et al., 2008).
COMPOSITION AND STABILITY OF TRADITIONAL PROCESSED
The sesame seeds are used for oil extraction and food purposes (Elleuch et al., 2007). The high stability of sesame oil towards oxidation could be attributed to its high natural antioxidants (sesamol, sesamolin and sesamin) together with tocopherols (Ali et al., 2007). The oil composition varies and depends on climatic conditions, soil type, plant maturity, variety and method of processing
