This study was aimed to make formulations of oil in water (O/W) nanoemulsion supplement from carrot extract and virgin coconut oil and to determine the content of beta-carotene as well as mineral K in supplements. Nanoemulsion supplements were made using two mixes of food grade surfactants, low hidrophylic-lipophylic balance (HLB) surfactant (span 80) and high HLB (tween 80), with various oil surfactant ratios. The optimization of nanoemulsions evaluated according to the size, characterization of pH, viscosity, turbidity, and mineral content. The results of size optimization using the Taguchi method showed that HLB and the speed of the homogenizer have significant effects on the size of nanoemulsion. Good nanoemulsion supplements are at HLB 10.3A with a globule diameter of 65.9 nm and PI 0.311, pH of 7.03, turbidity of 0.46 cm-1, viscosity of 2.4 cP, and beta-carotene content of 926.89 μg / 100 g of K mineral content of 0.058 μg/L, so that pro-vitamin A supplements made have the potential to prevent vitamin A deficiency |
