Abstract The optimal conditions for encapsulation of anthocyanin extract from Zea mayzs L. (purple corn) by using, a mixed design, was investigated. This study determined the best mixture ratio of Maltodextrin and Arabic gum as encapsulant agents and the effect of the inlet temperature on the response variables: yield, moisture and total anthocyanins concentration. The physico-chemical and morphological characterization of the obtained encapsulates was performed. The heat effect at temperatures of 45°, 60° and 75°C on the concentration of total anthocyanins was also evaluated as well as the color variation of the encapsulates at room temperature in a two-month-period.
