Changes of enzymatic discoloration and phenolic compounds evoked by cutting and ageing of celeriac slices were investigated. A significant accumulation of phenols and increase in enzymatic browning was observed during four days ageing of slices. A strong correlation between enzymatic discoloration and phenols (especially chlorogenic acid) was found.
