Recent research published in ‘Discover Agriculture’ has unveiled significant insights into the storage stability of Sudanese sesame (Sesamum indicum L.), an important crop known for its nutritional and economic value. Conducted by Mohammed Elsafy and his team at the Swedish University of Agricultural Sciences, the study explored how accelerated storage conditions—specifically high temperatures and humidity—affect the quality and longevity of sesame seeds.
The findings reveal that when sesame seeds were subjected to elevated temperatures of 55 °C and 60% relative humidity for periods of 16 and 32 days, several key changes occurred. Notably, there was an increase in seed color, linoleic acid levels, fungal growth, and peroxide value, indicating deterioration in quality. Conversely, the study noted a decrease in oil content, oleic acid, water activity, phytochemical compounds, and antioxidant capacity. These changes are crucial for producers and consumers alike, as they can affect the nutritional profile and shelf life of sesame products.
Interestingly, the research highlighted that despite these adverse conditions, the germination rate and the content of saturated fatty acids remained stable, suggesting that certain quality traits may be resilient even under stress. Among the ten Sudanese sesame genotypes evaluated, the landrace Abusundoug exhibited superior storage stability, characterized by lower fatty acid levels and higher phytochemical content. This finding could have significant implications for breeding programs aimed at enhancing the storability and overall quality of sesame seeds.
From a commercial perspective, improving the storage stability of sesame seeds can lead to reduced losses during storage and transport, ultimately benefiting producers and consumers. As sesame is a staple in many regions, especially in Sudan, enhancing its shelf life could help stabilize market prices and improve food security. Furthermore, the increased awareness of the importance of phytochemicals and antioxidants in food products aligns with growing consumer demand for healthier options.
The study underscores the necessity for further evaluation of these Sudanese sesame genotypes, which may offer valuable traits for breeding programs. By focusing on cultivars that demonstrate better storability and quality, the agricultural sector can innovate practices that not only improve product longevity but also cater to the evolving preferences of health-conscious consumers.
As the demand for sesame continues to rise globally, this research presents a timely opportunity for farmers, seed developers, and food manufacturers to collaborate on enhancing the quality and marketability of sesame products. By leveraging these findings, stakeholders can position themselves to meet market demands while contributing to sustainable agricultural practices.
