STUDIES ON THE METABOLISM OF ORGANIC ACIDS IN APPLES STORED AT LOW TEMPERATURE, IN CONTROLLED ATMOSPHERE.

ETUDES SUR LE METABOLISME DES ACIDES ORGANIQUES CHEZ LA POMME PENDANT ET APRES LA CONSERVATION AU FROID EN ATMOSPHERE CONTROLEE.

Author(s) : PHAN C. T., CORMIER F.

Summary

RESULTS ON THE EFFECTS OF CA 5% CO2, 3% O2 AT 277 K (4 DEG C) ON THE ORGANIC ACID CONTENT OF MCINTOSH AND GOLDEN DELICIOUS APPLES ARE PRESENTED. SUCCINIC ACID ACCUMULATES IN APPLES AFTER REMOVAL OF THE CONTROLLED ATMOSPHERE, NOT DURING STORAGE AS PREVIOUSLY REPORTED. A POSSIBLE EXPLANATION WOULD BE THAT SOME PHYSIOLOGICAL DISORDERS HAVE INDEED BEEN INDUCED DURING CA STORAGE BUT BECAME APPARENT WHEN ACTIVE METABOLISM HAD BEEN RESUMED. IT IS SHOWN THAT AT 277 K, WHETHER IN CA OR IN AIR, MALIC ACID IS CONVERTED INTO ANOTHER ACID THAT HAS NOT YET BEEN IDENTIFIED.
