| Abstract:
The nectarine cv "Independence" was kept in 0.3% O2 atmosphere and in air at 0°C and 6°C for 12, 21, 29 and 36 days to study the effect of low O2 atmosphere on the postharvest physiology and quality of the fruits. Ethanol and acetaldehyde content increased in low O2 atmosphere as storage time increases, particularly at 6°C. The correlation between ethanol and storage life was statistically significant. Low O2 treatment had no significant effect on methanol content. Flesh firmness and titratable acidity decreased along with storage period. Low O2 treatment can delay the decrease in firmness and acidity, but temperature did not affect firmness and acidity. A slow increase in SSC occurred during storage. SSC was not influenced by temperature, but fruit stored in 0.3% O2 atmosphere had less SSC than fruit stored in air. Higher correlations between ethanol and acetaldehyde, SSC, acidity and firmness were also observed. Nectarine fruits stored in 0.3% O2 atmosphere at 0°C and 6°C for 36 days did not have any detrimental effects and showed acceptable quality values. | |
