Annotation -
Polysaccharides are renewable source of natural biopolymers, which are widely used in food, paper, construction and chemical industries. In the frame of the course subject students are introduced to the sources, structure and physical properties of polysaccharides and their oligomers. Then physical-chemical methods which are used for analysis of polysaccharides will be described. A substantial part of the course is devoted to applications and nutritional importance of polysaccharides in their use in biocompatible food packaging

Aim of the course -

Students will be able:

To propose the method to evalute the polysaccharide structure and composition

On the basis of structure to propose the polysaccharide application in food

To evaluate the polysaccharide application as stabilizer, thickening or jellying ingredient in food formulation

To evaluate the nutritional benefit of polysaccharide in food or food supplements
