Despite a large number of studies performed on flavor/cloud emulsion, there is a lack of sufficient knowledge on the formulation of a desirable orange beverage emulsion in terms of the critical physicochemical properties.
The present study was conducted to investigate the effect of proportion of main emulsion
components (namely Arabic gum, xanthan gum and orange oil) on physicochemical properties of orange beverage emulsion.
In the present study, response surface methodology (RSM) was applied for modeling the possible relationships between the response and independent variables.
Response surface analysis can provide the response regression models for rapidly estimating the overall variation of physicochemical emulsion properties as a function of main emulsion components in a relatively short time.
In addition, the present study was conducted to optimize a desirable formulation for the orange beverage emulsion without using the unhealthy synthetic compounds such as weighting agents.
The main objective of present study was to determine an optimum level of independent variables resulting in (1) maximum emulsion stability, (2) minimum conductivity and size
index, (3) the largest magnitude of ζ-potential and (4) a suitable pH value depending on the other response goals.
