Spray drying represents a viable alternative for the stabilization of juice and extract of a great diversity of plant in tropical zones, such as jackfruit from Nayarit, Mexico. The jackfruit powder allows physicochemical and microbiological stability for storage, transportation, and marketing. In addition, this allows expansion of consumption and use of these exotic tropical fruits. The aim of this work was to find the best enzymatic hydrolysis and spray drying treatment for obtaining jackfruit pulp and juice in powder without affecting its rheological and physicochemical properties. Jackfruit pulp was treated with three commercial enzymes and their mixtures, and the best treatment was then optimized by Response Surface Methodology. The jackfruit pulp and the hydrolyzed juice were spray dried using maltodextrin as a carrier agent. The best hydrolysis was obtained with Celluzyme ® and Pectinex Ultra Pulp ® and the optimal conditions were 1% of enzyme concentration, during 3 h at 37 °C ( p  = 0.92), that leads reducing sugar of 78.50 ± 1.93 mg mL −1 and viscosity of 7.94 ± 0.82 cps (94.7% reduction). The enzyme concentration is a direct function of reducing sugars content, while incubation time is an inverse function of viscosity. The spray drying treatment with the highest yield (74%) without affecting rheological and physicochemical properties compared to the fresh hydrolyzed juice was the treatment with 50% (TSS/weight) maltodextrin.
