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.
塔罗科“圣阿尔菲奥”是一种晚熟血橙品种。由于含有包括维生素C、多酚、类黄酮和羟基肉桂酸在内的生物活性化合物，血橙因其高营养保健价值而越来越受到消费者的青睐。这项工作的目的是建立一个可靠的协议，用于极晚熟塔罗科“圣阿尔菲奥”橙子的采后贮藏，以延长该产品在市场上的供应时间，用于新鲜冷藏橙汁的生产。果实经过三种贮藏处理（1℃贮藏20天加4℃贮藏50天；4℃贮藏70天；20℃贮藏70天）。结果表明，冷藏处理，特别是持续在4℃下冷藏，可以延长塔罗科“圣阿尔菲奥”的货架期，提高总花青素含量。所确定的协议可以延长高价值产品的市场供应时间，并可能给柑橘产业和消费者带来相关益处。
