Abstract
The study provides a theoretical basis for deeply study and research on rebaudioside A sweetener. The rebaudioside A can be used in the diabetic's diet and people with phenylketonuria as a natural and non-caloriesweetener. The sweetener played an important role in yoghurt making. In this study,we investigated the effects of rebaudio-side A,erythritol and Isomalto-oligosaccharide combinations on sensory score,hardness,consistency,viscosity,pH and water-holding capacity of sugar-free yoghurt. A central composite rotatable design( CCRD) was adopted to obtain data for the correlative statistical models. Through the response surface analysis,the optimum formulation condi-tions of sweetener combinations based onsensory properties,texture,pH and waterholding capacitywere: rebaudio-side A 0. 02%,erythritol 1. 809% and IMO 2. 908%. In the above condition,the yoghurt color was milky white, perfect sugar to acid ratio and better texture.
