The Effect Of Tween 80 And Span 80 Combination As Emulsifier On The Ecapsulation Of Kenikir Flower Extract Using Maltodextrin Ecapsules

Abstract

This study aims to determine the effect of tween 80 and span 80 combination on the characteristics of  the kenikir flower dye extract encapsulate and determine the best combination of tween 80 and span 80  to produce kenikir flower dye extract encapsulates. This study is a one-factor experiment using a simple  randomized block design with a combination treatment of tween 80 (T) with span 80 (S), to achieve HLB  values of 8, 9, 10, 11, 12 and 13. Each treatment was carried out three times to get 18 units. The data  obtained were analyzed by analysis of variance and if treatment affects the observed variables, it was  continued with Duncan's Test. The results showed that the combination of tween 80 and span 80 as an  emulsifier affected the water content, total carotenoids, surface carotenoids, encapsulation efficiency,  brightness level, redness level and yellowness level and had no effect on the yield and solubility of the  encapsulated extract of kenikir flower dye extract. Based on the effectiveness index, the combination of  HLB 9 (Twen 80 0.18g and Span 80 0.32g) was the best combination to produce an encapsulate of  kenikir flower dye extract with the characteristics of 78.54% yield, 5.57% water content, 90.43%  solubility, total carotenoids. 27.59%, surface carotenoids 0.64%, encapsulation efficiency 97.70% with  brightness (L*) 35.92, redness (a*) 24.23 and yellowness (b*) 32.48.
