COMPARISON OF WEIGHT LOSS AND QUALITY CHANGES BETWEEN CRYOGENIC AND MECHANICAL FREEZING OF CATFISH.

Author(s) : REID D. S., MEYBECK A.

Summary

FRESH CHANNEL CATFISH WERE BATCH FROZEN IN AN AIR BLAST FREEZER (-37 DEG C) AND IN TWO LIQUID NITROGEN FREEZERS (-78 DEG C). RELATIVE WEIGHT LOSS DURING FREEZING WAS TWICE AS HIGH FOR THE MECHANICAL FREEZER, AVERAGING AROUND 1%. THE TEMPERATURE OF THE FILLET BEFORE FREEZING, AND LIPID CONTENT, INFLUENCED WEIGHT LOSS. NO DIFFERENCE WAS FOUND BETWEEN FREEZING METHODS IN TERMS OF OXIDATIVE RANCIDITY.
