Pigmentos de calamar gigante (dosidicus gigas)estructura química, actividad antioxidante y antimicrobiana y su aplicación como aditivo alimentario

Abstract

ABSTRACT Pigments play a key role in aposematism, attraction, mimicry, camouflage and protection against UV radiation. Among the pigments that develop these functions are the ommochromes. Ommochromes, like other pigments, produce color in the organism that synthesizes them, as well as exercising various biological activities. Ommochromes can act as antioxidants and their antioxidant mechanism generally follows the following mechanisms: they can bind metals and exert chelating activity, and they can act as primary antioxidants by eliminating radicals, such as singlet oxygen and superoxide anions. To explore a new source of compounds with multiple potentials, the objective of this doctoral thesis was to document the antioxidant and antimicrobial potential in vitro, as well as in the form of tuna pâté.
