The present invention relates to the preparation of a natural additive with antioxidant and antimicrobial properties obtained by spray drying from micro-and nanometric-sized colloidal systems, based on ingredients of natural origin, mainly consisting of essential oils incorporated in biopolymeric matrices. Also, the present invention discloses the preparation process of the micro-and nanoparticles and the conditions for the drying process taking into account sustainable and environmentally friendly technologies. La presente invención se refiere a la elaboración de un aditivo natural con propiedades antioxidantes y/o antimicrobianas obtenido por secado por aspersión a partir de sistemas coloidales tamaño micro- y nanométrico preparados con base en ingredientes de origen natural, principalmente constituidos por aceites esenciales incorporados en matrices biopoliméricas. Se describe el proceso de preparación de las micro- y nanopartículas, así como las condiciones para el proceso de secado, tomando en cuenta principalmente tecnologías sustentables y amigables con el medio ambiente.
