JA has been known as a good source of inulin-like fructans. In this present study, JAP was used as a natural source of inulin in cakes, and JAP was incorporated into cakes at a level of either 5 or 10%. Addition of JAP to cakes showed a significant effect on crust color of cakes while its effect on crumb color was insignificant. JAP addition reduced the specific volumes of cakes significantly. In general, the incorporation of JAP at a level of 10% reduced the softness of cakes. Inulin contents of cakes with 5 and 10% JAP were 10.4 and 23.7 mg/g dry matter, respectively. When the smell and color of JAP in cake formulations were masked with cocoa powder, panelists liked cakes with 5 and 10% JAP equally in terms of the crumb cell structure, flavor, smell, chewiness, sweetness and overall liking. In conclusion, when the discoloration of JA tubers was minimized during processing, JAP could be used as a natural source of inulin in cakes. This would increase the daily intake of inulin, which is a health-beneficial constituent of JA tubers for human nutrition.
