Proximate Analysis of Sesamum indicum (Sesame) Seeds and Physicochemical Parameters of Extracted Oil (Published)
This study investigated the proximate composition of Sesamum indicum L. seeds and the physicochemical properties of the extracted oil. Standard analytical methods were employed for all determinations. Proximate analysis revealed that the seeds contained 45.38% crude lipid, 22.70% crude protein, 19.35% carbohydrate, 5.87% ash, 3.72% moisture, and 2.98% crude fiber, indicating that sesame seeds are a rich source of oil and plant-based protein. The extracted oil was light yellow with a nutty odor and taste, a specific gravity of 0.910, acid value of 11.22 mg KOH/g, iodine value of 25.72 g/100 g, saponification value of 110.80 mg KOH/g, and peroxide value of 15mEq/kg, reflecting its nutritional and industrial quality and stability. These findings are consistent with previous studies, confirming the potential of sesame seeds as a valuable source of edible oil and essential nutrients. The results provide information relevant to nutritional, industrial, and commercial applications of sesame seeds in human and animal diets
