Optimization of formulation of CMC-Na,xanthan gum and carrageenan affecting the physicochemical properties of papaya-wolfberry beverage using response surface methodology

Cmc-na,xanthan gum and carrageenan are widely employed in food industry. they were used for its thickening properties of aqueous solutions or emulsifying abilities. the present work aims to optimize the formula of the three stabilizers in the process of papaya-wolfberry beverage by response surface methodology (rsm). the results showed that the models were significantly (p<0.05) fitted for describing the viscosity and cloudiness of papaya-wolfberry beverage. the results also indicated that the linear terms of cmc-na and xanthan gum were the most significant (p<0.05) variables affecting the viscosity,while xanthan gum and carrageenan were the most significant (p<0.05) variable affecting the cloudiness. the interaction of cmc na and xanthan gum behaved extremely significant for viscosity. from the optimization procedure,the best formula for viscosity was obtained at the combined level of 0.0652% (w/w)cmc-na,0.1070% (w/w) xanthan gum and 0.1485% (w/w) carrageenan,and the other group of 0.0623% (w/w) cmc-na,0.1375% (w/w) xanthan gum and 0.1461% (w/w) carrageenan for cloudiness. the results of our study would be used to improve the quality of papaya-wolfberry beverage and increase its economic efficiency.
