Summary

THREE SPECIES OF SCAMPI, METANEPHROPS ANDAMANICUS, M. BOSCHMAI AND M. AUSTRALIENSIS, WERE FROZEN ON BOARD SOON AFTER CATCHING. THESE SAMPLES, EITHER WHOLE ANIMALS OR TAILS, WERE EVALUATED AFTER 2, 6 AND 12 MONTHS FROZEN STORAGE AT 255 K (-18 DEG C). THE PROTEINS DENATURED SLOWLY. THE K-VALUE DECREASED SLIGHTLY, AS DID THE TOTAL NUCLEOTIDE POOL. THE TEXTURAL CHANGES WERE SLIGHT, BUT THERE WAS SOME LOSS OF CHARACTERISTIC ODOURS AND FLAVOURS, AND BOTH OFF-ODOURS AND OFF-FLAVOURS INCREASED. ACCEPTABILITY WAS SIGNIFICANTLY LOWER AFTER 12 MONTHS THAN AFTER 6 MONTHS, ALTHOUGH THE SCAMPI REMAINED GENERALLY HIGH IN ACCEPTABILITY. SCAMPI TAILS WERE MORE STABLE THAN WHOLE SCAMPI.
