ABSTRACT
Bioactive peptides are protein fragments with a positive impact on the human health. Peptides have shown several biological properties such as antimicrobial, antiviral, antitumor, among other activities and they are produced by almost all species. These peptides have attracted the interest of researchers and consumers due to the high potential use in functional foods, cosmetic and pharmaceutical industries, and other dietary interven-tions for disease control and health promotion. However, there are impor-tant topics of concern prior to the application of bioactive peptides. For that reason, this chapter reviews the recent trends in extraction, purifi-cation, and characterization of bioactive peptides. It includes the strate-gies and advances in extraction technologies of bioactive peptides from Technology, Volume 3 50different sources. Also, the purification methodologies employed in the last five years are discussed. Even more, it is presented the recent trends in the characterization of bioactive peptides, including bioactivities, toxicology, and the aminoacidic sequencing.
