The Andean blueberry (Vaccinium floribundum Kunth), also known as mortiño, presents a unique combination of several phytochemicals, which play a synergistic role in its characterization as a functional food. We aimed to expose the possible variations that exist in the profile of the phenolic compounds as well as the antioxidant and antimicrobial capacity of the wild Andean blueberry with respect to three ripeness stages and two different altitudes. We found that polyphenols are the predominant compounds in the berry during the early ripeness stage and are the main bioactive compounds that give rise to the antioxidant capacity and inhibition effect on the growth of gram-positive and gram-negative bacteria. Moreover, the accumulation of ascorbic acid, free amino acids, and anthocyanins increases as the ripening process progresses, and they were the main bioactive compounds in the ripe berry. The latter compounds influence the production of the typical bluish or reddish coloration of ripe blueberries. In addition, it was determined that environmental conditions at high altitudes could have a positive influence in all cases. Overall, our data provide evidence regarding the high functional value of the wild Andean blueberry. date: 2022-11 date_type: published publication: Molecules volume: 27 number: 21 pagerange: 7525 id_number: doi:10.3390/molecules27217525 refereed: TRUE issn: 1420-3049 official_url: http://doi.org/10.3390/molecules27217525 access: open language: en citation: Artículo Materias > Biomedicina Materias > Alimentación Universidad Europea del Atlántico > Investigación > Producción Científica Abierto Inglés The chemical composition and biological capacities of berries depend on environmental parameters, maturity, and location.
