Summary

THE ETHANOL CONTENT OF < HARRISON > AND < JERSEY > HIGHBUSH (VACCINIUM CORYMBOSUM L.) AND < PREMIER > RABBITEYE BLUEBERRIES (V. ASHEI READE) INCREASED LINEARLY WITH TIME (1 TO 4 HOURS) AND EXPONENTIALLY WITH TEMPERATURE 273 TO 303 K (0 TO 30 DEG C) DURING EXPOSURE TO AN ATMOSPHERE OF PURE N2 OR CO2. CO2 PRODUCTION WAS DEPRESSED ABOUT 20% UNDER N2 GAS. BERRIES WHICH WERE PLACED IN AIR AFTER 4 HOURS IN CO2 LOST HALF THE CO2 THEY CONTAINED EVERY 30 MINUTES. AFTER 3 HOURS, CO2 EVOLUTION FROM TREATED AND CONTROL FRUIT WAS THE SAME. QUALITY WAS UNAFFECTED BY EXPOSURE AT 273 TO 303 K TO PURE N2 OR CO2 GAS FOR UP TO 4 HOURS, BUT AFTER 22 HOURS IT IS REDUCED. AN EQUATION WAS DERIVED TO CALCULATE ETHANOL ACCUMULATION UNDER DIFFERENT COOLING RATES.
