Malnutrition and food insecurity remain persistent public health challenges in The Gambia, driven by limited access to affordable, nutrient-dense foods, the underutilisation of indigenous crops, and significant post-harvest losses. To address these issues, this study aimed to develop and evaluate reformulated snack bars using locally available ingredients such as millet, baobab, mango, and hibiscus. An online anonymous survey on snacking behaviour was conducted to assess consumption patterns, motivations, and nutritional gaps, revealing a strong demand for affordable, nutritious snacks and limited incorporation of local crops into daily diets.

In response, four millet-based snack bar formulations were developed, including variants with baobab, mango, hibiscus, and reduced fat and sugar options. Nutritional analysis using Nutritics software demonstrated improved levels of key nutrients, including vitamins A and C, iron, and calcium. Sensory evaluation among UK-based adults (n = 40) found the control bar to be the most preferred overall, though fruit-based variants were rated highly for aroma and appearance. A follow-up survey in The Gambia explored consumer responses to traffic light nutrition labelling, offering insights into purchasing behaviour and product appeal.

This research highlights the potential of underutilised local crops to create nutrient-rich, culturally relevant snack products, thereby contributing to both improved nutrition and reduced food waste. By bridging the gap between academic research and commercially viable products, this study supports sustainable food innovation aimed at addressing malnutrition in The Gambia through accessible and locally relevant solutions.
