Abstract

Response surface methodology was used to optimize spray-drying process for tomato paste with 10DE maltodextrin. Independent variables were: inlet air temperature (140–160 ºC) and feed low rate (350–600 mL h-1). Responses variables were powder yield, moisture, and total color difference. Inlet air temperature a positive effect on powder yield and total color differences and a negative effect on moisture content. Feed flow rate led to lower powder yield, but increased moisture content and total color differences. The best spray drying conditions to produce higher powder yield and lower moisture content and total color differences were inlet air temperature of 159 °C and feed flow rate of 350 mL h-1.
