FISH FRESHNE SS METER ENABLES THE OPERATOR TO ASSESS THE QUALITY AND FRESHNESS OF WET FISH SIMPLY AND EASILY. THE HAND-HELD INSTRUMENT IS SIMPLY PLACED IN CONTACT WITH THE FISH, A BUTTON IS PRE SSED, AND THE FRE SHNESS LEVE L OF THE FISH IS DISPLAYED ON THE LCD DISP LAY.

THERE ARE ORGANOLEPTIC CHARTS AVAILABLE FOR A LARGE SELECT ION OF FISH CAUGHT A ND PROCE SSED AROUND THE WORLD. YOU CAN CREATE YOUR OWN ORGANOLEPTIC CHART FOR OTHER SPECIE S OF FISH CAUGHT AND PROCESSED WORLD WIDE, A ND PROGRAMME THE METER WITH YOUR OWN DATA.

EXHAUSTIVE RESEARCH HAS CULMINATED IN THIS NON-DESTRUCT IVE, AND NON- INVA SIVE INSTRUMENT, AS AN ACCURATE AND RAPID METHOD OF OVERCOMING THE PROBLEMS OF EVALUATING THE RELATIVE FRESHNESS OF WET FISH.

BACKGROUND

THE FRESHNESS METER WAS DEVELOPED TO SATISFY A REQUIREMENT FOR AN OBJECTIVE METHOD OF EVA LUATING THE ‘QUALITY’ OF WET FISH, AND TO PROVIDE AN EST IMATION OF THE ‘RELATIVE’ FRESHNESS OF FISH LANDED AT PORTS FOR THE RETAIL SA LES AND PROCESSING INDUSTR IES TO JUDGE THE REMAINING SHELF LIFE OF A PARTICULAR SHIPMENT OF FISH

IT IS WELL KNOWN THAT THE RATE OF SPOILAGE OF WET FISH VARIES FROM SPECIES TO SPECIES. VARIOUS FACTOR S SUCH A S FAT CONTENT, HANDLING, STORAGE, BIOLOGICAL FACTORS AND SEASON OF THE YEAR CAN SIGNIFICANTLY A FFECT THE RATE OF SPOILAGE. SUBJECTIVE METHODS BASED UPON SENSOR Y EVALUATION ARE SLOW AND DIFFICU LT TO STANDARDISE IN THE FIE LD.

PRINCIPLE OF OPERATION

THE FRE SHNE SS METER MEA SURES CONDUCTANCE, CAPACITANCE AND Q-FACTOR OF THE FLESH A ND MU SCLE STRUCTURE. AS THE FISH SPOILS, A ND AS BACTERIOGICAL ACTIVITY INCREASE S, THERE IS A REDISTRIBUTION OF INTRA– CELLULAR AND EXTRA-CELLULAR E LECTROLYTES. THIS REDISTRIBUTION CHANGES THE CAPACITANCE AND RESISTANCE OF THE FLESH AND MUSCLE STRUCTURE. THESE CHA NGE S IN VA LUE A LLOW US TO CALIBRATE THE FRESHNESS METER’S RESPONSE. THEREAFTER IT IS A SIMPLE MATTER TO PREPARE AN ORGANOLEPTIC CHART, WHICH A LLOWS THE OPERATOR A N OBJECT IVE, CONSISTENT BASIS ON WHICH TO JUDGE THE FRESHNESS OF THE FISH UNDER TEST.

RESEARCH AND DEVELOPMENT OF THE INSTRUMENT WERE FIRST CONDUCTED BY MAFF’S TORRY RESEARCH STATION, ABERDEEN, SCOTLAND...USING A LARGE QUANTIT Y OF FISH OF DIFFERENT SPECIES. SINCE THEN MANY RESEARCH PROJECTS USING THE FRESHNE SS METER HAVE BEEN CARRIED OUT AROUND THE WORLD. TECHNICAL PAPER S ON THE MET ER, AND RELATED TOPICS, HAVE BEEN PUBLISHED. THE FRE SHNE SS METER IS MANUFACTURED IN THE UK BY DISTELL.COM.
