Description:
Awareness of health and nutrition of fish has led the food industry to development of fishery-based ready-to-eat
products. In this study seven filling materials based on 60-70 - 80 %fish mince from 7 local fish species ‘i.e.’
Talang Queen fish (Scomberoides commersonnianus), oriental sole (Brachirus orientalis), Barred sickle fish
(Drepane longimana), Big eye Croaker (Pennahia anea), Japanese threadfin bream (Nemipterus japonicas),
javelin grunter (pomadasys kaakan) and Indian mackerel (Rastrelliger kanagurta) were formulated and applied
for developing fish strudels. A 9-point hedonic scale ranging from 1 (extremely dislike) to 9 (extremely like) was
used for screening the acceptance of the prototypes. A 3-component D-optimal Mixture Design was also applied
to optimize the fish strudel formulation. Preliminary experiments were done to identify the high-impact
ingredients, which had a high effect on the sensory quality when their levels (%) were changed.
The results indicated that fish strudel containing 60% Talang Queen fish (Scomberoides commersonnianus)
mince in the filling materials had significantly higher liking in odor, flavor, and overall acceptability than the
other prototypes. So it was selected for quality changes study.
Product's characteristics and stability were studied during 6-month storage at -18 °C. The fish strudel packed in a
polyethylene sealed bag was stable during the storage period. The peroxide and TVBN values remained low.
The results in this paper provide important information for companies planning to develop convenience food
from low value fish. Furthermore, development of strudel filled with fish mince/ flesh could be an effective way
to enhance nutritional and functional value of such products. The products could be used as a nutritious snack
especially for kids which could be a means of increasing fish consumption.
