The evaluation of the sensory attributes given by the panelist during storage at
room temperature and a low temperature (4˚C) of osmotic dehydrated and CaCl2
infused purple sweet potatoes are shown in Table 2. Overall, the sensory qualities of
purple sweet potatoes such as color, odor, taste, texture, appearance and overall
acceptance were gradually decreased during storage under both temperatures (RT & 4˚C). The storage period has significantly influenced the qualities of osmotically
dehydrated potatoes (P≤0.05). The result showed that extended storage of potatoes
under both temperatures could not be able to withstand against consumer perceptual
test. Although, it is not at best, but a low-temperature storage could still able to have
better scores as compared to room temperature.
