Resumen:
Use of extracts of brown algae as shrimp functional additive can be beneficial due to the antioxidant activity of the polysaccharides contained in them. A first tool to select potential compounds that prevent oxidative damage and for the future development of functional food is to measure total antioxidant activity (AT) in vitro. However, it is necessary to ensure that these additives do not interfere with the absorption of nutrients, for example by determining in vivo digestibility, these parametres used to measure nutritional value of diets.The mains of this study were to determine the AT in hepatopancreas of A. longinarisin diets added with polysaccharide extracts of algae Undaria pinnatifida and Macrocystis pyrifera and assess apparent protein digestibility of these diets.
