Abstract
The invention refers to a process of forming shaped articles from starch, which process comprises: PA1 (a) heating a composition comprising a pre-processed and essentially destructurized starch/water material, at a water content in the range of from 10 to 20% by weight based on the weight of the composition to a temperature sufficient to essentially destructure the starch. PA1 (b) transferring the melt to a mold while maintaining said water content and PA1 (c) cooling the melt in the mold to a temperature below its glass transition temperature to form a solid shaped article and articles made by this process.
