The texture of CaCl2 infused osmotic dehydrated purple sweet potatoes are
shown in Figure 3. The texture was gradually decreased in the samples during storage
under room temperature and a low temperature (4˚C). The initial texture of
osmotically dehydrated and CaCl2 infused purple sweet potatoes was at 2690.7 prior
to the storage. The lowest level of texture found at room temperature storage, and it
was ranged 2433.8 at 10 days and whereas, potatoes stored at 4˚C was ranged lowest texture 2191.4 on 15 days and then it fluctuated throughout the storage. The texture
of purple sweet potatoes was decreased sustainably throughout the storage under
both temperatures. There were no significant differences found in the samples under
both temperatures (P≥0.05). The texture of osmotically dehydrated purple sweet
potatoes during storage significantly differed among the different temperature storage.
The texture was decreased in the samples that stored at room temperature more
quickly storage at a low temperature. Storage at room temperature the samples more
quickly texture softer due to microbial growth and solubilization of cell wall
polysaccharides in the samples as compared to a low temperature, in samples storage
here the gradual decrease of firmness observed (Znidarcic et al., 2006). It was found
that osmosed samples were considerably softer than untreated samples.
