No differences were found between varieties in sensory evaluated enzymatic
browning, but Rema and Draga had higher scores than Mari in after-cooking darkening. Jerusalem artichoke
tubers had higher contents of total phenolics, phenolic acids and citric acid in the autumn and
low contents in the spring, while it was the opposite for malic acid. None of the chemical parameters
investigated could explain the discolouration of the Jerusalem artichoke tubers.
