Abstract:
A study was carried out to compare the change in various quality parameters of Bombay
duck (Harpadon nehereus) fish under conventional sun drying and improvised solar drying
method using concentrating solar (CS) technology during storage at room temperature
under aerobic packaging conditions in Sunderban area of West Bengal. The results of the
current study revealed that there were no significant differences in the various quality
parameters of dried fish samples in both the drying methods. However a significant
(p<0.05) decreasing trend in protein content, hardness and fracturability was observed with
the advancing storage period. A significant (p<0.05) increase in the mean moisture
content, springiness value, water activity, thiobarbituric acid reacting substances value and
yeast and mould count was observed during the storage period in both the drying methods.
An absence in total plate counts of dried fish samples in both methods was observed
throughout the storage period.
