Abstract:
In this study, Response Surface Methodology (RSM) was used for optimising the refining process of crude wild walnut (Juglans regia L.), Heijuga oil (CWWO) of Manipur, India. Refining of crude wild walnut oil (CWWO) was conducted at different levels of refining parameters, phosphoric acid, caustic soda and bleaching earth. And also, different levels of refining temperature using design of experiment (DOE) method, response surface methodology (RSM) with Central Composite Design (CCD), Design Expert 11. Rotary evaporator unit is used to carry out the experiment of refining processes. Chemical properties are essentials in judging the suitability of oils in food preparation. The chemical properties are also responsible for storability of oils besides quality of end products. The important chemical properties judging the suitability of wild walnut oil are determined. The quality parameter for refined wild walnut oil (RWWO) monitored in this experiment was free fatty acid (FFA). The quadratic model was found appropriate to get the optimum results. The response Free Fatty Acid (FFA) was significantly affected by the selected process parameters and found as 0.7 (mg/kg) with phosphoric acid (%), bleaching earth (%), caustic soda (%) 1.25, 1.5, 2.55 respectively at temperature 850C for 30 minutes refining time.
