In present days organic food is more and more popular especially in the midst of consumers. The consciousness about food and feeding still grow up. Organic foods give a feeling of safety and higher nutritional value in comparison with conventional ones. In presented work four types of organic and conventional jam samples (black currant, sour cherry, strawberry and raspberry) have been used. In the marked samples of jam the content of dry matter, vitamin C, anthocyanins and phenolic compounds have been measured. The results obtained showed that organic jams contained significantly more dry matter, vitamin C, anthocyanins, phenolic acids, flavonoles and flavones in comparison with the conventional ones. The presented results are similar to the previous scientific results showing that organic food contained more bioactive compounds in comparison with conventional one.
