Nutritional Value And Content Of Bioactive Compounds In Raspberry Fruit From Organic, Biodynamic And Conventional Farms

Summary

Organic farming is very popular in the world. Biodynamic farming is less recognized both by practice and  science. There is very sparse data about the nutritional value of  biodynamic plant crops. The aim of the study was to investigate if there are significant differences in the nutritional value and content of bioactive compounds in raspberry fruit produced in biodynamic (BIOD), organic (ORG) and conventional (CONV) systems. The results were divergent - in 2016 ORG raspberries contained more bioactive compounds than CONV. In 2017 the results were opposite - CONV fruits had significantly higher level of bio compounds than ORG ones. Composition differences between BIOD and ORG raspberries were also not consistent and showing various trends in the subsequent study years. There is a need for long lasting studies looking for the main factors deciding about the composition of fruits in dependence on the cultivation system.
