Summary

STANDARD FISH FILLETBLOCKS PREPARED FROM 5 ANTARCTIC FISH SPECIES (NOTOTHENIA ROSSII MARMORATA, N. KEMPI, N. GIBBERIFRONS, DISSOSTICHUS ELEGINOIDES, CHAENOCEPHALUS ACERATUS) WERE TESTED FOR THEIR SUITABILITY FOR PROCESSING INTO FROZEN PORTIONS (BATTERED/UNBATTERED). PORTIONS WERE SEALED SEPARATELY AND STORED AT 245 K (-28 DEG C) FOR UP TO 3 YEARS. THE AMOUNT OF WATER SOLUBLE PROTEIN, FORMALDEHYDE, DIMETHYLAMINE AND PH VALUE DID NOT CHANGE, WHEREAS THE TOTAL VOLATILE BASE NITROGEN INCREASED SLIGHTLY. THIOBARBITURIC ACID NUMBER WAS SPECIES-SPECIFIC AND CHANGED THROUGHOUT THE STUDY. ISOELECTRIC FOCUSING ALLOWED A DIFFERENTIATION BETWEEN SPECIES INDEPENDENT OF FROZEN STORAGE TIME. SENSORY RESULTS OF D. ELEGINOIDES AND CH.ACERATUS CONFIRMED THE HIGH QUALITY OF THE RAW MATERIAL AND THE SUITABILITY FOR LONG TERM STORAGE. N. KEMPI INDICATED THAT THIS SPECIES WAS LESS SUITABLE FOR THE PRODUCTION OF PORTIONS.
