Tarocco "Sant'Alfio" is a late ripening blood orange cultivar. Blood oranges are more and more appreciated from consumers for their high nutraceutical value due to the presence of bioactive compounds including vitamin C, polyphenols, flavonoids and hydroxycinnamic acids. The aim of this work is to set up a reliable protocol for postharvest storage of the very-late Tarocco "Sant'Alfio" orange to prolong the availability of this product in the market to be used for fresh chilled orange juice production. Fruits were subjected to three storage treatments (20days at 1°C plus 50days at 4°C; 70days at 4°C; 70days at 20°C). The results indicate that cold treatments, in particular at 4°C constantly, can extend Tarocco "Sant'Alfio" shelf life enhancing total anthocyanin content. The defined protocols allow prolonging market availability of a high value product and could induce relevant benefits for the citrus industry and consumers.

采后处理对用于新鲜冰鲜果汁的Tarocco血橙果实的质量和化学参数的影响。

Tarocco“ Sant'Alfio”是晚熟的血橙品种。由于存在包括维生素C，多酚，类黄酮和羟基肉桂酸在内的生物活性化合物，血橙因其较高的营养价值而受到消费者的越来越多的赞赏。这项工作的目的是建立一种可靠的协议，用于后期特鲁克Tarocco“ Sant'Alfio”橙的采后储存，以延长该产品在市场上的可用性，以用于新鲜冷藏橙汁的生产。对水果进行三种贮藏处理（在1°C下20天，在4°C下50天；在4°C下70天；在20°C下70天）。结果表明，特别是在4°C下持续进行的冷处理可以延长Tarocco“ Sant'Alfio”的保质期，从而提高花色苷的总含量。
