Abstract This chapter provides a review of the properties and application of chitin and chitosan. In the first two sections role of chitin and chitosan in nature, as well as the sources for commercial production are discussed. These sections also go into structural and physicochemical properties of these biopolymers. The following section introduces the analytical techniques used for the characterization of chitin and chitosan. Chemical modification of chitosan is then discussed with some emphasis on the more common chemical derivatives. Industrial application is discussed as well as the application for water purification as well as agricultural uses and food preservation among others. The application in health care and pharmaceutical field is covered in the final sections. This includes the use of chitosan as a food supplement, a material for wound care products, and the use in drug delivery.

Abstract: The health effects of hydrocolloids are dependent on how they are incorporated into food. The contribution of each hydrocolloid is small and the health benefits of these compounds cannot be separated from those of other non-digestible carbohydrates. The impact of hydrocolloids on gastric emptying and small intestinal digestion and absorption is well established. More recent work has explored new sources and their mechanisms of action related to their fermentation to short chain fatty acids and their impact on the intestinal microbiota along with potential actions the short chain fatty acids may have on plasma lipids and satiety. This is of increasing importance given the current global epidemic in obesity.
