Maltodextrin

About This Product

Maltodextrin is produced by partially hydrolysing corn, wheat, tapioca or potato starch, stopping well short of conversion to glucose. It carries CAS number 9050-36-6 and is supplied as a white free-flowing powder, specified by dextrose equivalent, which is below 20 by definition. Its main industrial role is as a wall material in spray-drying encapsulation, and it is well suited to it for several reasons at once. It forms solutions of low viscosity even at high solids, so a concentrated feed can still be atomised; it dries to a glassy, low-permeability matrix that physically traps the encapsulated material and shields it from oxygen; it is bland, so it contributes no flavour of its own to the finished powder; and it is cheap enough to use as the bulk of the particle. That combination is why flavours, colours, fragrances, vitamins and oils are so often delivered as maltodextrin-encapsulated powders. DE governs the balance: lower DE gives better film formation and oxygen barrier, higher DE gives better solubility and emulsification. It is also used as a bulking agent, a carrier for dry blends and a binder. It is used in spray-dried encapsulation, flavour and fragrance carriers, dry blends and premixes, agrochemical formulations, adhesives and as a bulking agent. Bio Green Chem supplies maltodextrin to specification on dextrose equivalent, moisture, pH, ash, solubility, colour and microbiology.
