Schinus terebinthifolius Raddi has been used in the Brazilian folk medicine since a long time and now as phytopharmaceutical because of its antimicrobial, cicatrizant and anti-inflammatory properties. The aim of this work was to evaluate the influence of the inlet temperature and the Aerosil concentration on the characteristics of the spray-dried extracts from Schinus terebinthifolius Raddi by spray-drying method. The extracts were prepared from a 70 °GL ethanolic extract with a Buchi B 191 Mini-spray dryer with technological adjuvant into a ratio of 20:80; 25:75 and 30:70 (w/w) Aerosil®200: dried residue, in the inlet temperature range from 120 °C to 160 °C. The residual humidity, final yield and the moisture uptake profile at 90 % Relative Humidity (RH) were used as evaluation criteria. The response surface analysis showed that increasing the temperature and the Aerosil®200 concentration, lead to lower residual humidity and moisture uptakes. The best drying parameters were the inlet temperature of 140 °C and 30 % of Aerosil®200 concentration, resulting in yields over 80 %.
