Postharvest quality and sensory attributes of ‘pesca di bivona’ peaches (Prunus persica L.) during storage
2017
“Pesca di Bivona” ‘Murtiddara’, ‘Bianca’, ‘Agostina’, and ‘Settembrina’ are non-melting white flesh peach landraces characterized by a persistent aroma and excellent flavour highly appreciated by Italian consumers. The aim of this work was to assess the persistence of their quality and sensory profiles after storage at 0 °C for 28 days, using destructive and non-destructive analyses. The IAD index, measured either at harvest or at fruit removal from cold storage, was correlated to TSS, TA and firmness of all the landraces. ‘Settembrina’ and ‘Agostina’ harvested at the right ripening time (50.5 ± 4.3 N) and stored at 0 °C during 4 weeks kept harvest quality in terms of sensorial attributes, …
Quality Changes of Tropical and Subtropical Fresh-Cut Fruits Mix in Modified Atmosphere Packaging
2017
Application of passive modified atmosphere packaging (MAP) for shelf life extension of mixed pineapple slices, mango pieces and orange segments, was evaluated. Fruits of Ananas cv ‘Gold’, Mango cv ‘Keitt’ and Orange cv ‘Washington Navel’ were washed, sanitized, peeled and cut. Minimal processed fruits were packed under 2 different atmospheres, passive (air) and active MAP (70% N2, 10 %O2, 20 %CO2), and stored at 10±1 °C with 85±5% RH for 12 days. Changes in package atmosphere composition, weight loss, color, texture, pH, soluble solids, sensory attributes, were evaluated after cutting and at three subsequent stages of storage (the 3 day, 6d, 9d, and the 12 day). Color parameters L* and b* s…
Postharvest Application of Sulphur Dioxide Fumigation to Improve Quality and Storage Ability of "Red Globe" Grape Cultivar During Long Cold Storage
2017
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…
Instrumental and sensory analysis of eating quality of peaches and nectarines
2010
The influence of flesh firmness on consumer acceptance and its relationship with total soluble solids concentration (TSSC), titratable acidity (TTA) and sensory analysis was studied to understand their interaction in determining acceptance judgments, for different organoleptic typologies of peaches and nectarines. The investigation was carried out during summer 2006 on fruit of ‘September Sun’ and ‘Sweet September’ (low acid) peach (Prunus persica (L.) Batsch), and ‘Maria Dolce’ (low acid) and ‘Venus’ nectarines (Prunus persica (L.) Batsch, var. nucipersica). Sensory descriptors for peaches and nectarines were Flesh firmness, Sweetness, Sourness, Aroma, and Acceptability. The panel was able…

Gelso in Sicilia: qualità, caratterizzazione e comportamento dei frutti in post-raccolta
2019
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 EVALUATION OF FOUR LOQUAT CULTIVARS GROWN IN SICILY
2011
Chemical (soluble solids content, titratable acidity, pH), morphological (weight, longitudinal and transversal diameter, thickness of the flesh, number of seeds, peel colour), and sensorial characteristics of four loquat cultivars (‘Algerie’, ‘Claudia’, ‘Nespolone di Trabia’ and ‘Sanfilippara’) from mature, organically-grown trees in Sicily, were analysed. The determinations were carried out by traditional instrumental techniques, by a panel test and by an electronic olfactory system. A panel of 10 trained judges was used to determine intensity of some attributes in the sensory profile of the different cultivars, while the electronic olfactory system was used to identify possible difference…
