| Abstract:
A storage experiment to prevent physiological postharvest disorders, mainly woolliness and internal browning, was carried out on nectarine fruits. The use of short term treatments with high CO2 concentrations or warming up the fruits for 48 h at 20 °C before storage were tested. Also the effect of CA-treatments with CO2 up to 20 % in combination with reduced O2 was proved. Warming the fruit at 20 °C before storage prevented woolliness in the absence of elevated CO2 but did not affect internal browning. Further, it enhanced water loss and ripening and increased fruit softening markedly. High CO2 treatments before the storage period appeared to have only minor effects on preventing storage disorders. Conversely, high CO2 levels during the storage period, especially in combination with low O2, significantly delayed fruit ripening, kept the fruit firmer and prevented the development of woolliness and internal browning during shelf life. The fruits of this storage treatment were the best in sensoric panel test. No deleterious effect on flavour caused by high CO2-treatments could be detected in the fruits. | |
