The effect of main beverage emulsion components namely Arabic gum (7–13% w/w), xanthan gum (0.1–0.3% w/w) and orange oil (6–10% w/w) on physicochemical properties of orange beverage emulsion was determined by using a three-factor central composite design (CCD). The reduced models with high R2 (⩾0.80) values and non significant (p > .05) lack of fit were significantly (p < .05) fitted to the experimental data, thus ensuring a satisfactory fitness of the regression models relating the response to independent variables. The quadratic effect of xanthan gum had a significant (p < .05) term in all reduced models. The independent variables had the most significant (p < .05) effect on turbidity loss rate and viscosity ratio. The overall optimum region resulted in the desirable orange beverage emulsion was predicted at a combined level of 13% (w/w) Arabic gum, 0.3% (w/w) xanthan gum and 10% (w/w) orange oil.
