Descripción
Microcapsules of gum arabic or maltodextrin 20DE containing antioxidant molecules (AOx), for example, carotenoids and tocopherol derivatives, were prepared by the spray-drying technique. The properties of these microcapsules were evaluated by several techniques, such as dynamic light scattering, scanning electronic microscopy, and steady-state and time-resolved fluorescence spectroscopy of microencapsulated pyrene. The quenching of photochemically generated singlet molecular oxygen (1O2) by the AOx in homogeneous solvents as well as in microcapsule solutions was evaluated using time-resolved phosphorescence detection of 1O2. The quenching rate constant of the process, KQ AOx, was strongly dependent on the type of the AOx. These results are explained by compartmentalization effects of the AOx in the core of the microcapsules and the accessibility of 1O2. The contribution of the biopolymer as quencher of 1O2 was also investigated. The present results can be applied to the design of edible antioxidant microcapsules within the food and cosmetic industries. © 2010 American Chemical Society.
