Abstract
Two commercially important small variety fish of
north-east India, namely, Puntius sophore and Mystus
gulio were dried using indigenously made solar tent
dryer. The quality of the dried products was
compared with the market sample of dry fish dried
under open sun. Biochemical, microbiological and
organoleptic characteristics were compared. Moisture
and ash components were found higher in
market sample in addition to protein and lipid
degraded products. Although, bacteriological count
was within the acceptable limit in both the products,
fungal colonies were detected in market samples.
Rehydration properties of market samples were
lower than the solar tent dried products. The
average temperature difference in the peak hours
(12 – 3 o’clock) between outside and inside of the
solar tent dryer was 9.94oC and 11.43oC while
drying Puntius sophore and Mystus gulio respectively
for 3 days. Sensory scores for appearance, colour,
odour and texture of the solar tent dried products
were above 4 in the case of both the fishes, whereas,
in the case of market samples, the scores for the
similar quality attributes were between 3 and 4 and
were within the acceptable limit.
