Author(s) : CHATTOPADHYAY P., BOSE P. K., BOSE A. N.

Summary

AFTER RECEPTION, THE SHRIMP ARE CLEANED WITH CHLORINATED WATER, GRADED, WASHED AGAIN WITH CHILLED CHLORINATED WATER, WEIGHED AND PACKED IN TRAYS WITH ICE. THE CONVENTIONAL FREEZING PROCESS USES PLATE FREEZERS IN WHICH THE PRODUCTS ARE PLACED FOR 3 HRS AT 233-238 K. THERE WAS AN ATTEMPT TO DEVELOP FREEZING BY LIQUID NITROGEN SPRAY. IN THIS CASE, THE PRODUCTS ARE PACKED IN POLYETHYLENE BAGS, PLACED IN CARTONS AND STORED IN A COLD ROOM. WATER AT 276-278 K CAN BE SPRAYED AFTER FREEZING. A COMPARATIVE, QUALITATIVE, QUANTITATIVE AND ECONOMIC STUDY OF BOTH PROCESSES TENDS ONE TO FAVOUR THE DEVELOPMENT OF THE LIQUID NITROGEN PROCESS.
