Description
Summary:This study is carried out for clarification and encapsulation of water extract from Stevia rebaudiana Bertoni. Clarification was performed using adsorption method of acid activated kaolin. Encapsulation of S. rebaudiana extract was carried out using spray drying method. Product evaluation was performed based on concentration of stevioside and rebaudioside A, moisture content, hygroscopicity, and sensory. The content of stevioside and rebaudiosida A was determined by HPLC. Clarification of S. rebaudiana water extract by using acid activated kaolin was successfully reduce 95% green pigment and 65% yellow pigment. The content of stevioside and rebaudioside A in the optimal encapsulation products is 0.83% and 2.25%, respectively. Water content and hygroscopicity of sweetening products obtained were 9.8% and 12.91%, respectively. Sweetener products still have a lower level of sweetness based on organoleptic test results.
