Production and properties of spray dried Clinacanthus nutans using modified corn starch as drying agent

Clinacanthus nutans leaves is a medicinal plant with promising therapeutic effect. The objective of this study was to produce C. nutans powder using a spray dryer and to evaluate its physicochemical properties, followed by physical observation after 3 months of storage at room temperature (21±1°C)....
