Process for the production of a pyrogen-free fructan which is readily

A metabolizable blood plasma substitute is described which contains a starch ester with a molecular weight (Mw) of&gt;20000 Daltons and a molar substitution of 0.1 to 1.5 as a colloidal component. The starch ester is for example acetyl starch with a molecular weight (Mw) of 200000 to 230000 Daltons and a molar substitution of 0.3 to 0.5.

A pharmaceutical composition is described as well as the use of a starch ester for the production of such a pharmaceutical composition for peritoneal dialysis (CAPD) in particular for continuous ambulatory peritoneal dialysis. Starch esters which are particularly suitable are e.g. acetyl starch with a molecular weight (Mw) of 100000 to 200000 Daltons and a molar substitution of 0.3 to 0.5. Using the compositions according to the invention it is possible to carry out peritoneal dialysis without damaging the peritoneal epithelium. In addition it is not stored in the organs.

Pharmaceutical composition for peritoneal dialysis

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.

The present invention provides a process for the preparation of a plasma based on starch by the hydrolytic decomposition of an amylopectin-rich starch to a definite molecular weight and partial etherification to a definite substitution before or after the hydrolysis, wherein the hydrolytic decomposition is carried out at least partly with .alpha.-amylase, .beta.-amylase or pullulanase.
