Summary

THE AA. REPORT TESTS CARRIED OUT IN TWO INDUSTRIAL SLAUGHTER-HOUSES, I.E. THREE IN THE FIRST ONE AND TWO IN THE SECOND, IN ORDER TO STUDY THE EFFECT ON THE SUBSEQUENT STORAGE LIFE OF POULTRY CARCASSES, ON ONE HAND, OF VACUUM-PACKING, ON THE OTHER HAND, OF THE ABSENCE OF PRECOOLING PRIOR TO PACKING. IN THE FIRST TEST, 60 CARCASSES MADE UP THE CONTROL LOT, ANOTHER 60 WERE PACKED IN THE WARM STATE UNDER VACUUM IN AN AIR-PROOF BAG, THEN COOLED ONE HOUR AT 262 K (-11 DEG C), STORED AT 275 K (2 DEG C) AND EXAMINED AFTER 7, 10, 14 AND 17 DAY STORAGE (I.E. FOUR LOTS). IN THE SECOND TEST, 120 CARCASSES WERE ALSO PACKED IN THE WARM STATE UNDER VACUUM, 60 BEING COOLED TO 275 K FOR 6 HRS, 60 MAINTAINED FOR 3 HRS AT 262 K ; ALL OF THEM WERE EXAMINED AFTER 7, 10, 14 AND 17 DAY STORAGE. THE THIRD TEST AIMED TO EVALUATE THE EFFECT OF BREAKING IN THE COLD CHAIN ON THE STORAGE LIFE OF POULTRY PACKED IN THE WARM STATE UNDER VACUUM, COMPARED TO CONTROLS, ALL . THE PURPOSE OF THE FOURTH TEST WAS TO DETERMINE THE EFFECT OF THE PERMEABILITY OF PACKAGE ON THE STORAGE LIFE OF POULTRY WARM-PACKED UNDER VACUUM ; ALL CARCASSES WERE THEN MAINTAINED CHILLED AND EXAMINED AFTER 10 AND 14 DAY STORAGE. FINALLY, THE FIFTH TEST (96 CARCASSES) MADE IT POSSIBLE TO COMPARE THE EFFECT OF GROUPING (BY FOUR) OR OF INDIVIDUAL PACKING IN A PVC FILM ON THE GROWTH OF MICROBIAL FLORA FROM THE FIRST DAY TO 10-14 DAY NG STRICT SANITARY CONDITIONS OR FROM MAINTAINING THE COLD CHAIN.
