| Abstract | ||
| Ethylene as a plant hormone plays a major role in senescence and loss of fruit quality and shelf life of apples. In order to maintain quality and increase storability of Golab Kohanz apples, an experiment was conducted in split factorial design with four replications. Treatments were threee different storage temperatures (1, 4 and 20 °C), gas combinations with two levels (2% CO2 + 3% O2 and 4% CO2 + 1% O2) and two types of polymeric films (polyethylene and polypropylene). The flesh firmness, total soluble solids (TSS). Electrolyte conductivity (EC), pH, terrible acidity (TA), TSS/TA and rate of ethylene production were measured in 14 days intervals. The results showed that ethylene production rate at 1°C was lower and the packed fruits under 1°C with gas combination of 1% O2 + 4% CO2 and polypropylene film maintained TSS, TA, TSS/TA and tissue firmness values compared to other treatments. pH and TSS/TA of fruits showed an increased trend, while TSS and TA decreased through the storage of fruits. The changes of quality factors occurred with slower rate than controls. The results indicated that modified atmosphere packaging has led to extension of storability and retardation of softening rate in fruits compared to controls | ||
