Melon fortification with calcium by impregnation techniques using a vacuum and/or ultrasound and drying were combined to obtain a snack product. For the impregnation step, samples were immersed in a 2 g 100 mL -1 calcium chloride solution at 25 °C. The samples were dried at 60 °C and an air velocity of 2 m s -1 . The influence of the impregnation method on drying kinetics, mass variation, calcium content, water activity, color, and texture was evaluated. All dried samples had reduced water activity. The vacuum impregnated (VI) melons presented higher mass gain and drying time. It resulted in the highest calcium incorporation, increasing up to 13 times the calcium concentration of the samples. The samples dried after submitted to VI showed the greatest differences in color and hardness. However, VI was the most effective technique for calcium incorporation, being the only one capable of producing fortified dried melon.
