Summary

A FIXED TEMPERATURE FISH PROCESSING SYSTEM WAS DEVELOPED BY THE AUTHORS IN 1983, IN WHICH TUNA ARE SOAKED IN CALCIUM CHLORIDE BRINE TO A TEMPERATURE OF 228 K (-45 DEG C), WHEN THE FREEZING OPERATION IS SUSPENDED TEMPORARILY SO THAT THE SUPERFICIAL TEMPERATURE OF THE BODY CAN REACH ABOUT 270 TO 263 K (-3 TO -10 DEG C) IN ORDER TO RELAX STRESSES BEFORE FREEZING IS RESUMED. THIS PROCESS HAS SOLVED THE LONG-OUTSTANDING PROBLEM OF CRACKS ON THE SURFACE OF TUNA AND THE SYSTEM HAS BEEN TEST-PROVEN BOTH IN SHORE PLANT AND ON BOARD FISHING VESSELS. AS A RESULT, THE ENERGY-SAVING CALCIUM CHLORIDE BRINE-IMMERSION FREEZING SYSTEM HAS MADE A SUBSTANTIAL STEP FORWARD TOWARDS COMMERCIALIZATION.
