摘要: The effect of the inlet temperature on the quality of watermelon powder after spray drying was evaluated. Inlet temperatures of the drying air of 120, 130, 140, and 150 degrees C maintained water solubility of the watermelon powder at 96%. At 253 mu M/g, the ORAC value of the watermelon powder dried at 130 degrees C was the highest among all tested powders. The D-50 of the watermelon powder dried at 130 degrees C was 18.21 +/- 0.22 mu m with a span of 1.73 +/- 0.038, which was more uniform than that of other powders. The crystallinity of the powder dried at 130 degrees C was higher than that dried at both 120 and 150 degrees C and showed stronger thermal stability. Moreover, watermelon powder dried at 130 degrees C presented a similar aroma as the fresh watermelon juice when being solved. Hence, an inlet temperature of the drying air of 130 degrees C was the optimal temperature for the production of watermelon powder.
