Potential application of metal-chelate regenerable carriers in food pr
ocessing has been considered for laccase (EC. 1.10.3.2.) immobilizatio
n. Among the carriers tested, Sepharose 4B-Epi-IDA-Cu2+ with immobiliz
ed enzyme showed the highest activity towards phenolic compounds, remo
ving 75 and 69% of catechin from model solutions eluted from the start
ing and regenerated carriers, respectively. These carriers were also c
haracterized by high stability.
