Spray-drying is one of the methods used to dehydrate foods and prolong their life. This study aims to determine the optimum amounts of maltodextrin and rubber acacia to maximize °Brix and minimize the viscosity in banana pulp for later spray drying. The maltodextrin has a significant effect for both, the content °Brix as viscosity, but the latter also affects the interaction between maltodextrin and rubber acacia. It is necessary to find a balance between the maximum °Brix and minimum viscosity for the drying process. Low viscosity allows a better flow of the mixture in the spray system (disk or diffusion) and a high concentration of solids totals increases the performance of the final product. The combination of treatments generating the better answer is above 39.95 g maltodextrin with 3.29 g rubber acacia. This combination of treatments is the point where oBrix are maximum and viscosity is minimum, finding a value of 46.44 °Brix and 634.59 cP respectively.
