Organic agriculture is a production system completely different from the conventional one. In organic orchards it is forbidden to use artificial pesticides and mineral fertilizers. Only natural methods of soil fertilizing are allowed (cow manure, green manure, compost). Apricot fruits are one of the best sources of bioactive compounds from different chemical groups as carotenoids (beta-carotene, lutein, lycopene, zeaxanthin) as well as polyphenols (phenolic acids and flavonoids). Only natural preserving methods as drying, fermentation, light pasteurization are allowed. The experiment was carried out in 2015. Organic and conventional dry apricots have been obtained from shops with organic and conventional food. For a study purpose six dry apricot brands have been used (three for organic fruits and three for conventional). The content of dry matter and carotenoids have been measured in fruits. The obtained results showed that organic dry apricots contained significantly more dry matter, total carotenoids, lutein, zeaxanthin as well as beta-carotene in comparison to the conventional samples. Therefore is can be recommended to consume the organic dried apricots frequently.
