ABSTRACT

This study determined the effect of accelerated ageing on variability in oil yield and proximate composition of sesame seed accessions using the standard procedure of the Association of Official Analytical Chemists (AOAC). Sesame seeds were collected from the experimental farm of the National Cereal Research Institute (NCRI), Badeggi, Niger State, Nigeria. Results showed that NCRIBEN203 had the highest oil yield of 54.63±0.44%. Proximate analysis results indicated that NCRIBEN131 had the highest crude protein and crude fat contents of 25.29±0.26% and 52.82±1.44%, respectively, while NCRIBEN201 had the highest crude fibre content of 4.31±0.17%. The study revealed that accelerated ageing does not have a marginal effect on the mineral-rich profile of sesame seed accessions. Therefore, it is recommended that sesame seed accessions that exhibit superior and desirable qualities should be selected and cultivated for purposes of consumption and industrial use. Also, adequate measures such as drying should be employed to reduce the moisture content in sesame seeds before storage to prevent microbial growth and seed deterioration.
