SOME EFFECTS OF MODIFIED-ATMOSPHERE PACKAGING GASES ON FISH AND CHEMICAL TESTS FOR SPOILAGE.

Author(s) : DAVIS H. K.

Summary

THE MAIN NON-SENSORY INDICATORS OF SPOILAGE OF MARINE FISH PRODUCTS ARE SEEN TO BE AFFECTED WHEN APPLIED TO PRODUCTS STORED UNDER MODIFIED ATMOSPHERES. THE RELATIONSHIPS BETWEEN SCORES FROM SENSORY ASSESSMENT AND LEVELS OF VOLATILE AMINES, AND OF NUCLEOTIDE DEGRADATION PRODUCTS ARE DISTORTED AT STORAGE TEMPERATURES ABOVE 273 K (0 DEG C). THE MAIN CAUSES APPEAR TO BE LINKED TO THE GREATER EFFECTS OF CO2 AT LOW TEMPERATURES AND THE INDIRECT NATURE OF THE LINK BETWEEN CHEMICAL TESTS AND ORGANOLEPTIC RESPONSES. THE NEED FOR HIGH CONCENTRATIONS OF OXYGEN IS CHALLENGED.
