DIMETHYLAMINE (DMA) AND FORMALDEHYDE (HCHO) PRODUCTION IN FRESH RED HAKE (UROPHYCIS CHUSS): THE EFFECT OF PACKAGING MATERIAL OXYGEN PERMEABILITY AND CELLULAR DAMAGE.

Author(s) : LUNDSTROM R. C., CORREIA F. F., WILHELM K. A.

Summary

THE PRODUCTION OF DMA-N AND HCHO IN UNFROZEN RED HAKE IS RELATED TO THE AMOUNT OF OXYGEN EXPOSURE. THE DMA PRODUCTION RATE IS MINIMAL IN WHOLE RED HAKE AND RED HAKE FILLETS OR MINCE STORED IN PLASTIC TUBS WITH AIR PRESENT, AND MAXIMAL IN THE ABSENCE OF AIR. INTERMEDIATE DMA PRODUCTION RATES WERE OBTAINED WITH RED HAKE FILLETS OR MINCE VACUUM PACKAGED IN POLYETHYLENE (HIGH OXYGEN PERMEABILITY) OR PVDC (LOW OXYGEN PERMEABILITY) BAGS. OXYGEN EXPOSURE PLAYS A MAJOR ROLE IN THE MECHANISM OF DMA AND HCHO PRODUCTION. CAREFUL MANIPULATION OF OXYGEN EXPOSURE MAY YIELD A METHOD OF CONTROLLING THE PRODUCTION OF DMA AND HCHO, THUS PREVENTING UNDESIRABLE TEXTURAL CHANGES WHICH LOWER THE QUALITY AND DESIRABILITY OF THIS SPECIES.
