Weight loss of osmotically dehydrated and CaCl_2 infused purple sweet potatoes are shown in Figure 1. The results showed that weight was continuously decreased in the samples during storage under room temperature and low temperature (4˚C). Weight loss in the potatoes were ranged from 11.29 to 19.92%. The different temperature storage was significantly influenced the weight loss in osmotically dehydrated potatoes. The samples stored under room temperature was losing the potatoes weight more quickly than 4˚C. Weight loss was increased gradually throughout the storage under low temperature. However, when compared to the room temperature the low-temperature storage was controlled of weight loss better. 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 ..).
