Abstract
Quality changes in Labeo rohita; Cirrhinus mrigala and Tilapia mossambica were
studied during storage in ice and at ambient temperature (29-32°C). After 10 h at
ambient temperature L. rohita and T. mossambica were completely spoiled, while C.
mrigala became unacceptable within 11 h.
Organoleptic examination, total volatile base nitrogen and total bacterial c:ounts
showed that L. rohita (0.5 kg and above) and C. mrigala (0.5 kg and above) were acceptable
upto 7 to 8 days of storage in ice in popular container (Bamboo basket) lined with
palmyrah mat) at ambient temperature while T. mossambica (30-40 g) was acceptable
upto 6 days.
Influence of size of fish on shelf life in ice studied with reference to L. rohita
showed that fishes below 500 g were acceptable upto 6 days of storage in ice in popular
container at ambient temperature while those above 1000 g size were acceptable upto
8 days. Pro"Vision of an alkathene lining to the popular container extended the storage
life of L. roh;ta from 6 days to 8 days. Pre-chilled and iced L. rohita had a longer shelflife
(9 days) than merely iced sample (7 days)
