Aging of biopolymers and biocolloids studied by light scattering techniques

Popis výsledku v původním jazyce

Natural product such as biopolymers and biocolloids are often subjected to aggregation and degradation. Both these processes must be taken into account in the case of industrial application of these natural compounds. Aggregated or degraded material as araw material for industrial production can significantly change the final yield and properties of product. This contribution proposes the application of light scattering techniques for observation of stability of these compounds in time. As model biopolymers were used proteins (bovine serum albumin) and polysaccharides (chitosan, carboxymethylcellulose, glucose, sucrose and sodium alginate). Biocolloids were represented by humic acids. Stability and degradation of proteins and polysaccharides in time was studied using zeta potential (method of electrophoretic light scattering) and molecular weight (combination of size exclusion chromatography with multiangle light scattering detection). Aging of humic acids was investigated by means of
