Abstract

Umbu (Spondias tuberosa Arruda Câmara) fruit was analyzed for its physical, physico-chemical, and chemical characteristics at two stages of its physiological maturity (half-ripe and ripe). Half-ripe fruit was stored at different conditions: (1) ambient (27 ± 2 °C and 60–75% relative humidity) and (2) at refrigeration (9 ± 2 °C and 40–60% relative humidity) conditions. With the advance of maturation, the reducing sugars and soluble solids concentrations increased, while that of the titratable acidity and ascorbic acid contents decreased. The half-ripe fruits could be stored at refrigerated conditions for a longer period (10 days) when compared with the fruits stored at ambient conditions (only 6 days) without presenting any sign of senescence in the fruit. The higher index of °brix/acidity (6.81) in the fruits stored at refrigeration temperature for 10 days made these fruits much more appreciable from an organoleptic flavor standpoint when compared with fruits stored for only 6 days at ambient conditions.

Frutos de Umbu (Spondias tuberosa Arruda Câmara) fueron analizados por sus características físicas, físico-químicas y químicas en dos estados de maduración fisiológica (medio-maduro y maduro). Los frutos medio maduros fueron almacenados en diferentes condiciones: (1) ambiente (27 ± 2 °C y 60–75% de humedad relativa) y (2) refrigeración (9 ± 2 °C y 40–60% de humedad relativa). Con el avance de la maduración la concentración de azúcares reductores y sólidos solubles se vieron incrementados mientras la acidez titulable y ácido ascórbico se redujeron. Los frutos medio maduros pudieron ser almacenados a condiciones de refrigeración por un período más largo (10 días) si se compara con los frutos almacenados a condiciones ambiente durante sólo 6 días sin presentar ningún signo de senescencia. El alto índice de °brix/acidez (6,81) en frutos almacenados a temperatura de refrigeración durante 10 días hizo esos frutos ser mucho más apreciados desde el punto de vista de sabor organoléptico cuando se compara con frutos almacenados durante sólo 6 días en condiciones ambiente.
