In conclusion, the effect of spray drying conditions on the phys- icochemical and antioxidant properties of Gac fruit powders was investigated. Moisture content, bulk density, colour characteristics, TCC, EE and TAA were significantly affected by maltodextrin con- centration and by the inlet air temperatures. However, pH, aw and WSI were not significantly influenced by the different spray drying conditions in this study. The Gac powder spray-dried at in- let temperature of 120 °C and maltodextrin concentration of 10% was adequately effective in preserving colour, TCC and TAA. Strong positive correlations among TCC, TAA and colour characteristics were also confirmed.
