Color change of osmotic dehydrated purple sweet potatoes that infused with CaCl2 has shown in Figure 5. Overall, a decreased trend of color was found in osmotic dehydrated purple sweet potatoes that infused with CaCl2. Lightness values of potatoes were tend to increased. The highest level of color (L*, C*) was dropped in samples which were treated with 60% sucrose and 4% CaCl2. On the other level, Hue (H°) values were not significantly differed among each other. However, the samples that were treated with 60% sucrose and 4% CaCl2 were slightly decreased the H° value as similar to other results of color.
