Efecto de la encapsulación en secado por atomización de biocomponentes de pitahaya amarilla con interés funcional

Abstract

Yellow pitahaya contains biocomponents such as polyphenols with antioxidant capacity that may cause a physiological effect besides the nutritional aspects. However, these biocomponents are sensible to environmental conditions, processing, and/or gastrointestinal environment when they are consumed. Therefore, biocomponents were subjected to encapsulation by spray drying to evaluate the effect of this technique on their conservation. The results show that the most effective treatment was that performed at temperature of 150 °C with 40% maltodextrin, achieving longer stability of up to 72 hours for total polyphenols and 240 hours for the antioxidant capacity. In this way, it is guaranteed that release of these biocomponents will occur in the small intestine, where they are available for the body to adsorb them.
