Optimization of spray drying process of ginger oleoresin using response surface methodology

Abstract

In this study, response surface methodology was used to establish optimum conditions for microencapsulation of ginger oleoresin. The best microencapsulation was obtained using a combination of 20.7% maltodextrin, 4.2% gelatin, 10.0% oleoresin loading. This condition resulted in high microencapsulation efficiency (88.1%) and low moisture content (3.9%).
