| 摘要 |
A process is described for the production of starch degradation products with a narrow molecular weight distribution which is characterized in that a native starch, a starch derivative, a partially hydrolysed starch or a partially hydrolysed starch derivative in aqueous dispersion, suspension or solution is subjected to the action of ultrasound. Starch degradation products with a narrow molecular weight distribution can be obtained in high yields using this process.
