| Sesame seeds are a globally important food commodity and a high-quality source of cooking oil, particularly in Asia. This study profiled the levels of heavy metals (lead, cadmium, arsenic, mercury) and anti-nutritional factors (oxalate, phytate) in four sesame varieties available in Iran (two domestic: Behbahani, Lari; two imported: Pakistani, Sudanese). Oil was extracted by cold pressing, and analyses were conducted using atomic absorption spectroscopy (AAS) and high-performance liquid chromatography (HPLC). Lead ranged from 1.62-5.45 mg/kg, cadmium 0.45-0.99 mg/kg, phytic acid 0.76-1.50 mg/kg, and oxalic acid 64.01-169.49 mg/kg. The Behbahani variety exhibited the highest levels across all contaminants, while the Sudanese variety showed the lowest. The Pakistani variety had the highest calcium content, and the Sudanese variety had the highest iron, zinc, and magnesium concentrations. These findings highlight the significant varietal differences in sesame oil's | ||
