Effects of Water Soluble Materials on W/O Primary Food Emulsion Stability

Abstract

W ater-in-oil w/o primary food emulsions are often used for encapsulation of bioactive food ingredients or preparing multiple emulsions, however there is a lack of study about evaluation of stability of these emulsions by adding food materials in the dispersed phase. In this study, water-in-olive oil emulsions were prepared with using different dispersed phases; maltodextrin MD , whey protein isolate WPI and maltodextrin+whey protein isolate MD+WPI mixture 1:1 w/w solutions were used at different rates to determine the effects of dissolved material on physical, chemical, rheological and thermal properties of the emulsions. The kinetic stability of emulsions were significantly improved with increasing rates of soluble materials p
