In this study, the optimal conditions for the spray drying from Trametes versicolor (V.C.) extracts were determined using response surface method/technique (RSM). One kilogram of material was extracted with 30L ethanol 65% of 70oC for 7 hours. Solids were filtered off, extract was concentrated to obtain solution containing about 20% total solid using a vacuum evaporator. Study on the effects of three independent variables, namely maltodextrin ratio (% w/v), feed flow rate (ml/min) and inlet

The optimal conditions for spray drying process from T. versicolor extracts were found to be maltodextrin ratio of 5%w/v, inlet drying temperature of 160oC and feed flow rate of 26.05ml/min. The experimental values of TPC and MC were 35.76±0.04mg GAE/g, 4.43±0.02%
