ABSTRACT

The Ghani method is a traditional cold-pressing technique for extracting sesame oil (Tila Taila) using a heavy, circular stone grinding machine, typically powered by bulls or manually. This process helps retain nutrients and flavour while influencing the oil's composition and quality. This study examines the chemical composition and heavy metal content of Ghani-extracted Tila Taila. Standard physicochemical methods and GC-MS were used to identify key constituents, while ICP-MS analysed heavy metal levels. The primary fatty acids detected included 9,15-octadecadienoic acid methyl ester (Z, Z)-, n-hexadecenoic acid, 9-octadecadienoic acid methyl ester (E)-, 6-octadecadienoic acid, and octadecadienoic acid. Heavy metals such as Hg, Cd, As, and Pb were found within permissible limits. Rich in unsaturated fatty acids, antioxidants, and phytochemicals, Ghani-extracted sesame oil is beneficial for consumption. While traditional uses of Tila Taila are well-documented, not all have been scientifically validated. Ensuring rigorous quality control, particularly regardingheavy metal contamination, is crucial for its safety and efficacy.
