The purpose of the present work is to study the effect of inlet drying
temperature (140-170oC), feed flow rate (20-30ml/min) and maltodextrin ratio (10-
20%) on the total phenolic content (TPC) and total flavonoid content (TFC) of spraydryed Nelumbo nucifera extracts using response surface method/technique (RSM). The
optimal conditions for spray drying process from leaves of N. nucifera extracts were
found to be inlet drying temperature of 141oC, feed flow rate of 30ml/min and
maltodextrin ratio of 10%w/v. The experimental values of TPC and TFC were
36.89±0.05mg GAE/g and 9.22±0.02 mgCE/g
Nelumbo nucifera; total phenolic content (TPC); total flavonoid TFC; response surface methodology (RSM).
