Resumo
Nanoencapsulation based on natural polysaccharides effectively protects and improves
the bioavailability of different bioactive compounds. Food polysaccharides have
essential functional properties to compose targeted delivery nanosystems in the
intestine. This chapter describes the characteristics of the leading natural polysaccharides used as nanocarriers for application in food products. Also, it demonstrates
the principal methodologies used for elaboration and applicability, indicating the
characterization methods mechanisms for the formation and targeted release. The
essential biomaterials for this purpose are chitosan, cellulose, and pectin, which
can be used alone or combined with proteins to form nano-gels with multiple functionalities. Several methodologies can be used for preparation, such as molecular
self-organization and ionic gelation. Nanoencapsulated bioactives based on these
polysaccharides can be protected, maintain functional properties, thus increasing
the absorption and bioavailability. Biocompatibility, biodegradability, and nontoxicity are the highlighted advantages of these biopolymers. In addition, they can
be extracted from sustainable sources, such as industrial by-products. Several studies
have proven the advantages and relevancy of biomaterials for protection against the
environment, factors intrinsic to human digestion, and enhancing the beneficial
effects of biologically active compounds. Nanoencapsulation based on polysaccharides effectively enables the inclusion of these compounds in foods or to develop
new dietary supplements.
