The present study investigated how different storage conditions affect antioxidant levels in three scab-resistant and powdery mildew-tolerant apple cultivars. The contents of carotenoids, along with free and glycosylated phenolic acids, were quantified in harvested apples and apples stored in boxes with controlled atmospheric conditions (1.2% O2 and 2.2% CO2) and temperature (1 °C), boxes with regulated temperature (1 °C) and storage rooms with a temperature between 1 and 4 °C.

Antioxidants (phenolic acids and carotenoids) in selected apple varieties - harvested and stored

The aim of this work was to determine the concentration of selected carotenoids (neoxanthin, violaxanthin, antheraxanthin, lutein, zeaxanthin and ß-carotene) and phenolic acids in selected scab resistant and powdery mildew tolerant apple varieties originating from the Station of apple breeding of the IEB. We investigated three different apple varieties - Luna (yellow), Red Topaz (red) and Karneval (streaked) for their antioxidant contents in peel and flesh immediately after the harvest and after 7 months of storage.
