Abstract
Oil sardines in prime condition were chilled onboard. Two lots were chilled in
CSW (samples C & CI), one lot ice (sample I) and a fourth lot was left un-iced on
deck (sample AI). Sample AI was iced after landing and sample CI was taken out
of the chilled seawater and. iced. All the four samples were kept in a chilled room for
storage studies. Sample C, chilled and stored in CSW, recorded a gradual gain in
weight and an increase in salt content of the muscle. Presence of salt did not seem
to cause any excessive protein denaturation. Salt extractability decreased at a
gradual rate in all cases. Presence of salt seemed to wield no noticeable influence on
lipid hydrolysis and subsequent peroxidation. Results of chemical and sensory
evaluations highlight this. Holding sardines in CSW gave a product of excellent
quality for the first four to five days of storage. Beyond the fifth day of storage
quality deteriorated rapidly and there was no noticeable superiority for this sample
(sample C) over the onboard iced fish. This was evident in the sensory evaluation
as well. However, a storage life of five days in a readily acceptable state is sufficient
for the fish to be disposed in the market at a premium sale price over other landings
of the same species.
