Microencapsulation of Ocimum gratissimum L. Essential Oil Using Spray-drying

Abstract

This study was conducted to investigate the factors affecting on micr drying method. Various parameters were clearly investigated including concentrations of maltodextrin as wall material (20% 30 %), concentration of essential oils (0.5% temperature (130 -140 ), and feed flow rate (from 4 ml/min to 10 ml/min). The suitable conditions were the maltodextrin concentration of 25% (w/w), the concentration of essential oil of 1.5% (w/w), roto , and feed drying rate of 6 ml/min. The microencapsulation efficiency and the microencapsulation yield were 94.68% and 80.74%, respectively.
