Method of preparing thermoplastic starch from native starches, in particular for technical uses, and thermoplastic starch obtained using that method

摘要

The purpose of the notification is the production of thermoplastic starch from native starches, which is characterised by the fact that from 30% mass to 60% mass of native maize starch, or native maize starch of wax, or the sodium potato starch is mixed in the presence of 5% of the 10% acetic acid solution and with the addition of a plasticiser consisting of 10%of the glycerol mass to 20% the glycerol mass and 25%the glycerol mass to 45% the mixture is concentrated until compact granules and Squeeze. The notification also covers thermoplastic starch produced from natural starches,in particular for technical uses characterised by containing from 30% mass to 60% mass of maize starch, or maize starch, or potato starch, from 25% mass to 45% mass stabilised municipal effluent, from 10% mass to 20% mass glycerin and 5% mass solutions of 10% acetic acid.
