Abstract

 

Sesame, Sesamum indicum L. is one of the oldest and important oil seed crop in the world. The sesame seed apart from providing edible oil is also rich in protein. This study was carried out to evaluate the chemical composition and oil quality of seeds of 13 accessions of sesame grown in the Nsukka plains of South eastern Nigeria. The treatments which comprised of the 13 accessions were laid out in a randomized complete block design (RCBD) experiment in three replications. At maturity, samples of seeds were taken to the laboratory for chemical analysis. The result revealed significant variation in chemical composition and oil quality of the seeds of the sesame accessions. Percentages moisture, protein, fibre, fat, carbohydrate and ash in the seeds ranged from 5.0 to 8.0, 17.08 to 20.90, 1.40 to 2.40, 28.0 to 46.0, 27.63 to 44.85 and 1.10 to 2.90, respectively. The ranges of iodine value, peroxide value, acid value and free fatty acid were 76.14 to 130.07 g/100 g, 1.01 to 7.61 meq (H2O2), 0.67 to 2.85 mg/g and 0.34 to 1.43 mg/g, respectively. Highest percentage fat was recorded in the accession Yobe gadaka while Parchequeno had the highest percentage protein among the accessions.
