Preliminary Observations on Changes in NUcleotides in Oil Sardine and Certain Penaeid Prawns During Chill Storage

Abstract

Preliminary study has been made of the changes in common 5'
nuc]eotides in oil sardine (Sardinella /ongiceps) and two penaeid
prawns of Indian waters during chill storage. The course of nucleotide
degradation has been foilowed in the fresh fish and shell fish during
ice storage. The level of inosine monophosphate (IMP) in prawns
showed significant but steady decrease during ice storage and this
appears to serve as useful indication of length of storage. Comparison
has been made on the pattern of nucleotide changes in block frozen
fish and individually quick frozen fish stored at -23°C.
