Abstract
Sesame (Sesamum indicum L.) is one of the most ancient and valuable oilseed crops, ranking second in nutritional value after olive oil. After harvest, sesame seeds are typically stored for several months. Storage conditions significantly affect the quantity and quality of the extracted oil as well as the seed quality. Therefore, determining optimal storage conditions to preserve the qualitative characteristics of sesame oil and seeds is crucial for reducing post-harvest losses.  In this study, sesame tolerant to seeds loss samples were stored under two environments (ambient conditions and refrigerated conditions) using three packaging types (unpackaged, cloth bags, and layer paper bags) for twelve months. Every three months, samples were evaluated for acidity, peroxide value, aflatoxin levels, and seed germination percentage using a factorial experiment in a completely randomized design.  The results showed that the effects of storage environment, packaging type, storage duration, and their interactions on the evaluated traits were significant (P < 0.05). While the quality of oil and seeds declined over time, mean comparisons indicated that this decline was not significant (P > 0.05) for up to nine months in refrigerated conditions with paper bags, six months with cloth bags, and three months without packaging. The germination percentage of sesame seeds in cold storage was also significantly higher in all packaging materials and in both storage environments in paper bags throughout the storage period. The results indicated that the optimal storage conditions for sesame seeds, with minimal changes in the qualitative and microbial characteristics, were achieved over nine months in cold conditions using layer paper bags for packaging.
