ABSTRACT:
A destructurized native starch material is described which has a water content in the range of about 10 to 25% by weight and that its mass average molar mass is reduced by a factor of 2 to 5000 compared to its original mass average molar mass. The destructurized starch is produced by heating a chemically non-modified starch material having a water content in the range of about 5 to 25% by weight of the total weight of the composition in the presence of a chain scission catalyst in a closed volume to an elevated temperature sufficient to form a thermoplastic melt and until the mass average molar mass is reduced by a factor of 2 to 5000.
