INFLUENCE OF EXTREMELY LOW OXYGEN STORAGE ATMOSPHERES ON THE RESPIRATION BEHAVIOUR OF APPLES |

| Abstract:
Temperature, CO2 and O2 contents, as is generally known are the most important factors to influence metabolic and respirative processes and thus storability of fruit and vegetables. Several years' studies on the respiration activity of apples showed that under practical CA storage conditions increased CO2 contents in the atmosphere have relatively little effect on respiration activity. A temperature decrease near to the freezing point, however, leads to a distinct reduction in respiration intensity. Reduced O2 contents are even more effective than a temperature decrease. Since any negative effects on the fruit had not been observed in storage tests on different apple varieties in controlled atmospheres with 3 % CO2 and as little as 1 % O2, the influence of oxygen concentrations below 1 % were studied in the last two years. The results obtained in these experiments are reported. | |
