Apple fruit quality was investigated on scab‐resistant apple cultivars 'Santana', 'Liberty' and Topaz' and on scab‐nonresistant cultivar 'Golden Delicious' when they were grown according to either organic (ORG) or integrated production (IP). Trees subjected to similar crop load were used to asses physicochemical and sensorial parameters of fruits on both production systems. ORG produced 'Santana', 'Liberty' and 'Golden Delicious' had on the average smaller fruits and more soluble solids (with exception of ‘Topaz’) and higher flesh firmness (equal in case of ‘Golden Delicious’). Higher total phenol content in ORG fruits was found on the average in all investigated cultivars, however only in case of 'Golden Delicious' the difference was statistically significant. The change of phenol content in 'Golden Delicious' might be related to either its higher synthesis or to changes in fruit size. In order to elucidate which classes of phenols were affected by the production management, both ORG and IP cultivars were further analyzed by targeted metabolomics method for multiple classes of phenolics. In conclusion, the sensorial evaluation indicated significant better overall flavor and more acceptable overall appearance of IP produced apples.
