The aim of our work was the non-invasive maturity determination of Golden Delicious apples during 35 days long cold (2°C) and shelf-life storage (20°C). Significant difference was found between cold and at 20°C stored samples in case of mass loss, acoustic stiffness coefficient, RGB color parameters and chlorophyll content related parameters (IAD, F0, FM, FV/FM). The DA-value and the chlorophyll fluorescence values did not show significant differences between the blushed and shaded sides of the samples. All the applied non-invasive measuring methods were found to be suitable for the detection of postharvest maturation related quality changes of apple.
