| Abstract The objective of this study was to investigate optimized conditions for producing water-in-oil-in-water (W/O/W) microemulsions and spray-dried microcapsules of tomato extracts. The condition of highest yield for W/O/W microemulsification was optimized by response surface methodology (RSM). The independent variables were ratio of tomato extract to MCT (X 1: 1:9-2:8), concentrations of emulsifier (X2: 0.50-1.00), and ratio of W/O to secondary aqueous coating material (X 3: 1:5-1:9). According to the RSM results, the ratio of tomato extract to MCT at 1.24:8.76 (v/v), concentration of emulsifier at 1.00% (w/v), and ratio of W/O phase to secondary aqueous coating material of 1.00:6.16 (v/v) were found to be the optimal conditions for producing... |

| Abstract The aim of this study was to optimize conditions for producing water-in-oil-in-water (W/O/W) nanoemulsion and spray-dried nanocapsule of red ginseng extract. Based on emulsion stability and average particle size analysis, optimum conditions to produce W/O/W nanoemulsion were: ratio of core to coating material, 3:7; primary emulsifier, 10% polyglycerol polyricinoleate; ratio of W/O phase to coating material, 1.5:8.5; secondary emulsifier, 10% polyoxyethylene sorbitan monolaurate; solvent, 20% ethyl acetate; secondary coating material, 10% maltodextrin (MD). Under these optimized conditions, particle size of spray-dried nanocapsules coated with MD of red ginseng ranged from 100 nm to 500 nm, based on response surface methodology with the highest... |
