PRESERVATION OF KIWIFRUIT UNDER CONTROLLED ATMOSPHERE STORAGE IN A PILOT PLANT SCALE

This present study was carried out to evaluate the behavior of kiwifruit, CV. “Hayward”, grown in Greece and preserved under controlled atmosphere conditions in a pilot plant scale.
The experiment was carried out in two years under the following storage conditions:

1. 5.5% O₂, 1.5% CO₂ + C₂H₄ control

2. 5.5% O₂, 3.5% CO₂ + C₂H₄ control

3. Ethylene control (only) in normal refrigerated conditions.

In all cases, control samples in normal refrigerated conditions and two packaging means, such as common plastic boxes and wooden trays covered with plastic cups of about 20 kg and 3 kg of fruit were used respectively.

During the first two months of storage, a rapid decrease in firmness was observed followed by a slight decrease up to the end of the storage period.
Soluble solids content (SSC) and reducing sugars followed a similar trend to firmness.
A slight decrease in ascorbic acid content, titratable acidity (TA) and pH values were also noticed.
Packaging means significantly affected only the weight loss.

The fruits were preserved in a very good condition for move than 200 days, when stored under CA conditions while fruits of control samples and ethylene control samples, were preserved for only 120 and 140 days respectively.
