57Fe Mössbauer spectroscopy was used to determine the oxidation state and microenvironments of iron in the Fe-polygalacturonate compound prepared by a novel method from pectin. ICP analysis was applied to study the iron content of the coordination compounds. It was found that there are two ferrous and one ferric microenvironments in the compound. In the iron- polygalacturonate compound the ferrous forms occur dominantly. A model for the bonding of Fe in the polygalacturonate chains is proposed.
