<italic>Citrus aurantium</italic> var. <italic>dulce</italic> (sweet orange) belongs to one of the largest genera of the Rutaceae family. The species of this genus are consumed worldwide fresh or in form of beverages. They include well-known crops lemons, oranges, mandarins, grapefruits, and limes.
