A study on preliminary approach to the development of a predictive modelling of a process for depolymerisation of cassava non-starch carbohydrate using oxalic acid and ionic salt (potassium iodide) is reported. The effects of three independent variables namely; oxalic acid (0.0278 M) potassium iodide ( 0.241 M) at volumetric (mL) range of 2-10 and 0.05-1.00 for oxalic acid and potassium iodide respectively with heating range time (min) of 60 to180 were studied using the central composite rotatable design in a 23 factorial experiments. Hydrolysate markers namely: solubility index and reducing sugar were evaluated as a measure of depolymerisation consequently used as responses in the study. Equations for predicting the responses were developed and their adequacy confirmed using analysis of variance and residual assessment. The predictive model provides insight to the potentials of using oxalic acid as depolymerisation agent for cassava non-starch carbohydrate in the presence of potassium iodide salt. This would open a new opportunity for depolymerisation of cassava non-starch carbohydrate using foodgrade depolymerisation agent with view to yield product that its application will not be limited by safety concern.

Abstract

A study on preliminary approach to the development of a predictive modelling of a process for depolymerisation of cassava non-starch carbohydrate using oxalic acid and ionic salt (potassium iodide) is reported. The effects of three independent variables namely; oxalic acid (0.0278 M) potassium iodide ( 0.241 M) at volumetric (mL) range of 2-10 and 0.05-1.00 for oxalic acid and potassium iodide respectively with heating range time (min) of 60 to180 were studied using the central composite rotatable design in a 23 factorial experiments. Hydrolysate markers namely: solubility index and reducing sugar were evaluated as a measure of depolymerisation consequently used as responses in the study. Equations for predicting the responses were developed and their adequacy confirmed using analysis of variance and residual assessment. The predictive model provides insight to the potentials of using oxalic acid as depolymerisation agent for cassava non-starch carbohydrate in the presence of potassium iodide salt. This would open a new opportunity for depolymerisation of cassava non-starch carbohydrate using foodgrade depolymerisation agent with view to yield product that its application will not be limited by safety concern.
