Weight loss in the purple sweet potatoes that were undergone for osmotic process are shown in Figure 1. Weight loss of purple sweet potatoes decreased in during storage at both temperature. Weight loss shown significant after different temperature storage in potatoes. Weight loss lowest (11.29%) and highest (19.92%). The samples stored at room temperature was losing the weight more quickly than 4˚C. Osmotically Dehydrated purple sweet potatoes could able withstand for 25 days under low-temperature storage. Whereas, room temperature storage was not successful on extending the shelf life (10 days) of potatoes due to microbial growth (see Figure..).
