Storage of cv. "Salustiana" and cv. "Valencia" oranges and its influence on the fruit quality

Abstract

[SPA] Dos variedades de naranja, cv "Salustiana" y cv "Valencia", se conservaron bajo diferentes condiciones de temperatura (Tª), humedad relativa (HR), y atmósfera controlada (AC). Las naranjas cv "Salustiana" se mantuvieron durante 93 días en tres cámaras frigoríficas. Las naranjas cv. "Valencia" se mantuvieron en tres cámaras frigoríficas durante 153 días en cajas de tamaño industrial empleando nuevas condiciones de Tª, HR y AC. Se presentan resultados obtenidos durante el almacenamiento durante el cual se valoraron diferentes alteraciones y pérdida de peso. Las alteraciones valoradas fueron envejecimiento, escaldado y daño por frío que variaron según las condiciones fijadas en las cámaras: el daño por frío disminuyó a concentraciones altas de CO2, la pérdida de peso y el envejecimiento se relacionaron con temperaturas altas y stress del fruto manifestado por emisiones altas de volátiles. [ENG] Two types of orange, cv "Salustiana" and cv "Valencia", were stored under different temperature (T), relative humidity (RH), and controlled atmosphere (CA) conditions. "Salustiana" oranges were stored in three cold store rooms during 93 days. "Valencia" oranges were stored in three cold store rooms during 153 days into industrial type of boxes under new cold storage (T, RH, CA) conditions. The results, obtained during the storage are showed. Damages on the oranges and loss weight were evaluated. The damages evaluated were aging, scald and cold pitting which showed changes according to the conditions set up in the store-rooms. Chilling injury decreased under high-level CO2 concentrations; the weight loss and the aging were related with high-level temperatures and the fruit stress was manifested itself by high-level volatiles production
