Abstract

We have studied the effect of sodium ethylenediaminetetraacetate on enzyme-induced degradation of apple pectin. Capillary viscometry and IR spectroscopy data have shown that the ligand binds Ca2+ ions (present in pectin) thus accelerating its biodegradation 1.2–1.6 times at relatively low concentration of the complexone. At the same time, sodium ethylenediaminetetraacetate reduces enzymatic activity of lytic enzymes thus slowing down pectin hydrolysis as higher concentration of the complexone.
