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 was found in the potato samples storage at 4˚C . On the other level, Hue and chroma (H*, C*) values of potatoes were tend to decreased were 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.
