Summary

THE ETHANOL CONCENTRATION OF < CARLOS > GRAPES INCREASED LINEARLY WITH TIME (1 TO 4 HOURS) AND EXPONENTIALLY WITH TEMPERATURE 273 TO 303 K (0 TO 30 DEG C) DURING EXPOSURE TO A N2 OR CO2 ATMOSPHERE. ETHANOL LOSS FROM GRAPES PLACED IN AIR AFTER 4 HOURS IN CO2 WAS DEPENDENT ON THE CONCENTRATION OF ETHANOL ACCUMULATED DURING ANAEROBIOSIS. FRUIT QUALITY WAS UNAFFECTED BY 273 K EXPOSURE TO A CO2 ATMOSPHERE FOR UP TO 72 HOURS AFTER 6 HOURS IN CO2 AT 303 K. HOWEVER, 30 HOURS IN A CO2 ATMOSPHERE AT 303 K REDUCED FRUIT QUALITY. AN EQUATION WAS DERIVED TO CALCULATE ETHANOL ACCUMULATION DURING COOLING UNDER ANAEROBIC ATMOSPHERES.
