The high water-soluble pectin content
measured in chitosan-C coated slices could be related to the
chelating action by citric acid of calcium ions from the cell wall.
Thus, the pectate could be solubilized faster by enzymatic reactions
to water-soluble pectin. An increase in water-soluble or chelatorsoluble
polyuronide occurs in most fruits during ripening,
including kiwifruit
