In the heart of Sudan, a battle against malnutrition is being waged, not with swords or shields, but with a humble flatbread called Kisra. This traditional fermented bread, a staple in Sudanese cuisine, is at the center of a groundbreaking study led by Tilal Sayed Abdelhalim of the Biotechnology and Biosafety Research Center, Agricultural Research Corporation, Shambat, Khartoum, Sudan. The research, published in Frontiers in Nutrition, delves into the sensory acceptance and quality of Kisra made from biofortified and non-biofortified sorghum cultivars, offering insights that could revolutionize the fight against micronutrient deficiency.
The study, which involved 100 assessors aged 18–75, used the rate-all-that-apply (RATA) technique to evaluate nine different Kisra products. The results were striking: Kisra made from the biofortified Dahab cultivar received the highest overall liking scores, with participants rating it an 8 out of 9, indicating they “like very much.” Blends like Dahab + Dabar and Dahab + Arfa-gadamek also showed moderate sensory acceptance, scoring around 7.
The research didn’t stop at taste tests. It also explored the demographic factors influencing overall liking. Education level emerged as the most significant factor, accounting for 51% of the variance, followed by consumption frequency (25.5%) and age (23.5%). This data could be a game-changer for market segmentation, allowing food producers to tailor their products to specific consumer groups more effectively.
The RATA model used in the study demonstrated high assessor repeatability (0.994), homogeneity (0.904), and low global error (9.617). This method’s effectiveness in identifying key sensory attributes—such as porousness, thickness, and sourness—could pave the way for more nuanced product development in the future. “The RATA model’s ability to capture the complexity of consumer preferences is a significant step forward,” says Abdelhalim. “It allows us to understand not just what consumers like, but why they like it.”
The implications of this research extend far beyond the borders of Sudan. In a world where malnutrition remains a pressing issue, biofortified crops offer a sustainable solution. By enhancing the nutritional content of staple foods like sorghum, we can combat micronutrient deficiencies without compromising on taste or cultural significance. As Abdelhalim notes, “The acceptance of biofortified Kisra by consumers is a promising indicator that we can make a real difference in the fight against malnutrition.”
This study, published in Frontiers in Nutrition, is a testament to the power of interdisciplinary research. By combining sensory science, nutrition, and consumer behavior, researchers have opened new avenues for addressing global health challenges. As we look to the future, the insights gained from this research could shape the development of more nutritious, culturally acceptable foods, ultimately improving the lives of millions.
