Abstract. The Ericaceae agraz or mortiño is a promising fruit, is considered as a functional food for its high content of anthocyanins, antioxidants and vitamins. It is a highly perishable fruit that quickly loses its commercial and nutritional quality. The objective was to evaluate the behavior of unripe fruits harvested at three maturity stages and stored under refrigeration. It was used a completely randomized design with 3x3 factorial arrangement, where the first factor was the storage temperature: 1, 8 and 20 °C; the second factor corresponded to maturity: 3, 4 and 5, which was established according to the color of the fruit skin; it was made measurements of fruit quality. The results indicated that the fruits stored at 8 °C in maturity stages 3 and 4 retained characteristics commercial grade to 45 days and only state 5 to 25 days. While the fruit at room temperature retained life to 21 days in different maturity stages evaluated. The state 3 fruits stored at 1 °C had higher firmness and total titratable acidity, high total soluble solids content and lower maturity ratio. To maintain the agraz fruit quality for longer time, it is recommended to harvest at state 3 and then be stored at 1 °C.
