DEVELOPMENT OF A NON-DESTRUCTIVE TEST FOR FIRMNESS MEASUREMENT DURING COOL STORAGE OF KIWIFRUIT.

Author(s) : NICOLAS J.

Summary

THE AUTHORS INVESTIGATED WHETHER THE MEASUREMENT OF THE DEFORMATION OF KIWIFRUIT UNDER A 700 G LOAD COULD BE A NON-DESTRUCTIVE CRITERION. PHYSICAL AND CHEMICAL CHANGES WERE MEASURED AFTER 1, 2, 4, 6 AND 10 WEEKS AT 273 K (0 DEG C). IN ADDITION, SAMPLES WERE PERIODICALLY SUBJECTED TO MEASUREMENTS OF DEFORMATION UNDER 700 G AND IMMEDIATELY COOLED AGAIN TO 273 K. DURING 10 WEEKS, WEIGHT LOSS WAS ABOUT 4%, SKIN AND PULP FIRMNESS DECREASED BETWEEN 63 TO MORE THAN 90%, DEFORMATION AND COMPRESSIBILITY WERE MORE THAN TWICE GREATER, AND THE SUGAR CONTENT, THE REFRACTION INDEX AND THE MALIC ACID CONTENT INCREASED WHEREAS TITRATABLE ACIDITY AND CITRIC ACID CONTENT FLUCTUATED. NO DIFFERENCE WAS OBSERVED BETWEEN THE CONTROL SAMPLES AN HE UBECED TO 5TIS TOTOS FINALLY, THIS IS LINKED TO OTHER DESTRUCTIVE CRITERIA FOR KIWIFRUIT RIPENING.
