In both cases, temperature control is the most critical factor in fruit ripening management. The aim of this study was to investigate the quality evolution of mature-green and mature-ripe mango fruit submitted to 8°C and 90 ± 5% of relative humidity to assess the possibility to prolong its postharvest life. Materials and methods - The fruit of mango (Mangifera indica L. cv. Kensington Pride) grown in a Mediterranean environment was s…

Postharvest Application of Sulphur Dioxide Fumigation to Improve Quality and Storage Ability of "Red Globe" Grape Cultivar During Long Cold Storage

Table grape cv 'Red Globe' is produced in Sicily and in other areas of Southern Italy. This produce is very appreciated by consumers, having the best rankings in the world market for exports and quality. Nevertheless, despite it is a non-climacteric fruit, table grape is very perishable, both after harvest, and during postharvest handling and cold storage. In fact, also at low temperatures, table grape is very sensitive to fungal infection (Botrytis cinerea) and other diseases, like gray mold, which is very aggressive. For this reason, a standard practice is to fumigate table grape with sulphur dioxide (SO2), after storage in chambers. The growing market request of table grape cv. 'Red Glob…

Gelso in Sicilia: qualità, caratterizzazione e comportamento dei frutti in post-raccolta

Il gelso è una pianta arborea originaria dell'Asia e della Persia, introdotta in Italia dai Romani per le sue proprietà medicinali, oltre che per fini alimentari. Si distinguono due specie principali, comunemente denominati: gelso bianco e nero. I frutti, tipiche more di colore bianco violaceo o nero, sono molto apprezzati dall'uomo sin dall'antichità, sebbene vengano spesso collocati tra i frutti minori per la loro scarsa diffusione commerciale. Oggi, l'elevato interesse per le proprietà nutraceutichedi tali frutti spinge gli agricoltori ad una rivalutazione della gelsicoltura. Punto dolente della commercializzazione del gelso è la gestione post-raccolta a causa della brevissima shelf-life…

Fruit Quality Traits of Six Ancient Apple (Malus domesticaBorkh) Cultivars Grown in the Mediterranean Area

ABSTRACTToday, ancient cultivars have been considered obsolete and replaced, leading to a dramatic loss of genetic diversity. In this trial we examined the quality of the six ancient apple cultivars: Bommino, Gelato, Miliadeci, Rotolari, Turco, and Virchiata. Fruit was submitted to the determination of physicochemical traits and a sensory profile was defined by a trained panel using 20 attributes. We also detected biometric data using a specific descriptor list. Obtained data showed interesting physicochemical and sensory traits among the observed cultivars. ‘Rotolari’, ‘Bommino’, and ‘Gelato’ should be used in breeding programs and revaluated for a placement on specific local markets.
