Charakterisierung v.Biopolymeren - Characterization of Biopolymers

Paper and board industry use starch of different origin (maize, potatoes) for differnt purposes in large amounts. The aim of the project is to get information of changes in the quality of the used materials (geographic origin, changes during storage, influnece of year of production) by different methods. Part one of the project should provide fast methods which are are able to describe the different materials. Time consuming and expensive techniques should be replaced by Near Infrared Spectroscopy (NIR). Part two will investigate the use of natural polymer materials (chistosane, xylane, galactomannane) as substitutes for starch.
