Process optimization for micro-encapsulation of marigold colorant

Author(s):
Priti Jain and Mohan Singh
Abstract:
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.
