Abstract This study investigates the possible utilization of starch extracted from jackfruit seed waste from the jackfruit frying industry. We first compared the physico-chemical properties of jackfruit seed starch (JFSS) with cornstarch (CS) and potato starch (PS) and then compared JFSS with CS as a thickener and stabilizer in chilli sauce. JFSS had a higher amylose content and its granules were much smaller than CS and PS granules; in addition, JFSS had a higher pasting temperature and final viscosity than CS and PS. JFSS experienced lower breakdown than CS and PS pastes which indicates that JFSS paste is more resistant to thermal and mechanical shear during cooking. The XRD patterns showed JFSS to be Type A starch, similar to corn starch. JFSS is suitable as a thickener and stabilizer in chilli sauce because chilli sauce with JFSS had the lowest serum separation and highest viscosity during storage compared with control chilli sauce and sauce containing CS. In addition, sensory evaluation demonstrated that chilli sauce containing JFSS received the highest score in terms of color, mouth feel, homogeneity and overall quality.
