ABSTRACT

Chitosan is a natural polysaccharide obtained by the partial N-deacetylation of chitin, which is the second most abundant polymer in nature after cellulose. Additionally, it has functional properties that confer a variety of applications in the food industry and bioengineering, such as the encapsulation of bioactive compounds (fatty acids, enzymes, proteins, vitamins, antioxidants). Also, substance management systems have gained considerable attention as they are based on both natural and synthetic polymers. Chitosan micro- and nanoparticles have been studied as carriers for controlled release of vitamins due to their significant biological and chemical characteristics such as biodegradability, biocompatibility and bioactivity. This review presents the advances in recent years in micro- and nanoparticles based on chitosan in the supply of vitamins related to food science.
