The growing prevalence of ultra-processed foods in Uganda is driving the double burden of malnutrition. Overweight and obesity are on the rise while the intake of micronutrients remains insufficient. Simultaneously, jackfruits that are rich in minerals and vitamins remain underutilized. Its large size, sticky insides, and high perishability make it challenging to handle and cause high postharvest losses. In an attempt to address both issues, the present study investigates the potential of long-lasting, nutritious, and sugar-free jackfruit-nut-bars (JNBs) as a channel to enhance and promote the utilization of jackfruit, and provide healthier options of processed foods. To analyze consumer demand for the products, we first assess the sensory perception of four different JNBs at a university campus in Uganda. We then use Van Westendorp’s price sensitivity meter to elicit consumers’ willingness to pay (WTP) and identify factors shaping their demand. The results show that the sensory properties are, on average, rated positively, and price preferences are similar to established snacks. Based on our findings, we conclude that JNBs provide an option to enhance jackfruit utilization. A random effects model shows that WTP increases with sweetness, age, and frequency of snack consumption that JNBs can potentially substitute. These findings help future development and promotion of processed jackfruit products.
