'''Pullulan''' is a ] consisting of ] units, also known as α-1,4- ;α-1,6-]'. Three ] units in maltotriose are connected by an α-1,4 ], whereas consecutive maltotriose units are connected to each other by an α-1,6 ]. Pullulan is produced from ] by the ] '']''. Pullulan is mainly used by the cell to resist ] and ]. The presence of this polysaccharide also facilitates diffusion of molecules both into and out of the cell.<ref name=Rehm>{{cite book |author=Rehm B.H.A |year=2009 |title=Microbial production of biopolymers and polymers precursors |page=230 |publisher=Caister Academic Press }}</ref> |

As an edible, mostly tasteless polymer, the chief commercial use of pullulan is in the manufacture of edible films that are used in various breath freshener or ] products such as ] Cool Mint of Johnson and Johnson (USA) and Meltz Super Thin Mints of Avery Bio-Tech Private Ltd. (India). Pullulan and ] can also be used as a ] substitute for drug capsules, rather than gelatine. As a ], it is known by the ] E1204. |
