Summary

SPOTTED SHRIMP WERE STORED HEAD-ON AND HEAD-OFF ON MELTING ICE IN AIR AND CONTROLLED ATMOSPHERE FOR 14 D. PURE CO2 WAS ALLOWED TO FLOW THROUGH THE CONTROLLED ATMOSPHERE CHAMBER AT THE RATE OF 0.5 L/MIN MAINTAINING A 100% CO2 ATMOSPHERE. BACTERIAL COUNTS INCREASED MORE RAPIDLY AND TO HIGHER LEVELS IN AIR PACK THAN CONTROLLED ATMOSPHERE SAMPLES. THE LEVELS OF AMMONIA WERE VERY LOW IN THE FRESH SHRIMP AND INCREASED TO 21 AND 16 MG% IN HEAD-ON AND HEAD-OFF AIR-PACK SAMPLES, RESPECTIVELY, AND TO 12 AND 6 MG% IN SIMILAR SAMPLES STORED IN CO2. WEIGHT LOSS WAS GREATER FOR SHRIMP STORED IN CO2 THAN IN AIR. SENSORY EVALUATION SHOWED AIR-PACK HEAD-OFF SAMPLES TO BE UNACCEPTABLE AFTER 14 D OF STORAGE BUT CO2 -PACKED SAMPLES HAD ONLY MODERATE DISCOLOURATION AND NO DETECTABLE OFF-ODOURS.
