Abstract: Starch was processed from freshly harvested cassava, dried and stored for dextrin production. The starch was mixed separately with HCl and HNO3(nitric acid) as catalysts at different concentrations, temperatures and times. This was to determine the effect of the process parameters on the production of yellow dextrin. Temperature range of 50 to 90°C was adopted while acid concentration range of 0.1 to 0.5 M and time range of 20 to 60 minutes were used for the dextrinization process. The process parameters for the dextrinization of starch was optimized using Central Composite Design (CCD) expert Stat-Easy 360. The results obtained showed that the temperature of 80°C and roasting time of 30 minutes with concentration of 0.4 M using HCl gave a dextrin with the highest solubility of 76.596%, while using Nitric acid, temperature of 80°C, roasting time of 30 minutes and concentration of 0.4, M gave a Dextrin with the highest solubility of 53.6172%.
