Process optimization for micro-encapsulation of marigold colorant

Priti Jain and Mohan Singh
The present study aims to optimize the dryer parameters (inlet air temperature and feed flow rate) for the process development of marigold colorant from marigold petals extract. A lab spray dryer was employed for the spray drying process. Parameters analyzed were moisture content, solubility, hygroscopicity bulk density, colour, and product recovery. A response surface methodology with three inlet air temperatures (150, 160 and 170 °C) and three feed flow rate levels (80, 120 and 160 ml/h) were investigated. The independent variables significantly affected the physico-chemical properties of the marigold colorant. The optimized condition for spray dried marigold colorant was inlet air temperature of 166.4 °C and feed flow rate of 120 ml/h.
