Calidad poscosecha de frutos de pitahaya (Hylocereus undatus Haw.) en tres estados de madurez

The objective of the research was to evaluate the post-harvest quality of red dragon fruit in three stages of maturity. The treatments were initial maturity (25-50%), average (50-75%) and complete (75-100%), depending on the skin color. The fruits were stored in a cold room at 20 ° C. The design was completely randomized with three treatments, seven replicates and 21 experimental units. The experimental unit was made up of 20 fruits. Weight, firmness, total soluble solids, acidity and maturity index were recorded at 0, 3, 6 and 9 days after harvest. The fruit weight was significantly influenced by the maturity stages (p 0.05). Acidity and total soluble solids also showed a downwardly linear behavior over time, statistically significant differences (p 0,05). Acidez y sólidos solubles totales también mostraron un comportamiento descendentemente lineal en el tiempo, se encontraron diferencias estadísticas significativas (p<0,05) entre tratamientos, el estado de madurez completa obtuvo la mayor acidez y concentración de grados Brix en todos los tiempos evaluados. El índice de madurez fue afectado significativamente por los estados de madurez (p
