The localisation of pectin in Sphagnum moss leaves and its role in preservation

► Pectin is abundant throughout the hyaline and chlorophyllous cell wall. ► Acid-dissociation of pectin carboxyls explain the preservation properties. ► Salmon fillet exudate incubated inside/surrounding hyaline cells smelled fresh. ► Chlorite-treated Sphagnum has a potential commercial application in preservation.
