After removal of water‐soluble pectin from senescent Idared apples, an additional sizable pectin fraction could be extracted using Na 2 EDTA under nondegradative conditions. This chelator‐soluble fraction did not appear to owe its insolubility in the cell wall solely to molecular charge. The galacturonic acid‐rich polymers of chelator‐soluble pectin were notably lower in arabinose galactose and rhamnose residues than those of water‐soluble pectin.
