Abstract: The aim of the study was to identify physico-chemical properties,
SEM (Scanning Electron Microscopy) and sensory characteristics of dendeng made
from shark flesh (Chiloscyllium sp.). Three drying methods were used
in this study and they were sun drying, oven drying and oven vacuum drying.
Before drying, the slices with dimension of 4 cmx12 cmx3 mm were soaked in a
mixture of sugar (20%), salt (1%), tamarind (4%), coriander (1.5%), galangal
root (2.5%), ginger (0.5%), garlic (1.0%) and onion (1.0%) for 12 h. The drying
was carried out until the moisture content reached 23-25%. Proximate analysis
showed there were no significant differences among these samples but had significant
influence (p<0.05) on the color. The lightness value for vacuum drying was
32.19 followed by oven drying (29.97) and sun drying (28.92). There were no
significant differences in mineral values except for sodium (Na). SEM photograph
shows that different drying methods affect the compactness of the tissue structure.
Sensory evaluation result indicated that all samples were moderately acceptable
but there were no significant difference among the samples. However, shark dendeng
using oven drying was most preferred. |
