Chitosans with different chemical compositions (F A =0.05–0.65) and different molecular weights (M w =36.000–460.000) were studied by size-exclusion chromatography combined with multi-angle laser light scattering (MALS) and viscosity detectors to provide R G –M and [η]–M data as basis for further analysis using the wormlike chain model. In both cases intrinsic persistence lengths...
The chemical composition of shrimp shells from the deep-water shrimp (Pandalus borealis) obtained from a local factory in northern Norway that were harvested from January to December (2000) in the Barents Sea was investigated. The average dry matter content of the samples of shrimp shells was 22±2%, with no significant seasonal variation. The protein content was found to vary between 33% and 40% of...
