UN NUOVO PARCO PER UN PAESAGGIO ANTICO STORIA E CRONACA DI UN PAESAGGIO DELLA CAMPAGNA URBANA DI PALERMO
2012
Palermo’s landscape was characterized by centuries of wonder. The contemporary city has swallowed up a large part of it. It’s still surviving an exceptional scenery of the landscape of an area more than twenty times higher than that of the historical city. Today, a few surviving urban green areas also have a role in countering the increase of “heat island”, phenomenon that manifests itself with average temperatures of 3-5° C higher than those of the surrounding green areas, and that involves the growth of energy consumption for summer air conditioning of buildings. Green urban areas also play an important role with regard to hydrogeology and provide a vast reservoir of biodiversity. With th…
Quality changes during postharvest life in white fleshed peach (Prunus Persica L. Batsch) fruits: Preliminary observations
2016
Sicilian white flesh peach fruits ecotypes are characterized by a persistent aroma and excellent flavor that is highly appreciated by consumers. Nevertheless, they reach only regional markets, because of fruit sensitivity to decay and the poor information about their postharvest physiology and shelf-life. In this trial, we studied quality changes during postharvest life of non-melting white-flesh peach ecotypes ‘Tudia’, ‘Bella di Bivona’ and the cultivar ‘Daniela’. Fruits were collected at commercial ripening: a first group was submitted to analytical evaluations and another one was stored (2°C, 90% RH) for 32 days. During this storage period, fruits were submitted to four shelf-life period…
Effetti dell’applicazione di Edible Coating sul comportamento fisiologico e sulle caratteristiche fisico-chimiche, nutrizionali e sensoriali in prodo…

L’incremento demografico e il cambiamento dei ritmi e degli stili di vita della società moderna hanno visto un mercato sempre più globalizzato nonché lo sviluppo di nuove dinamiche nel settore agroalimentare e la crescente richiesta da parte dei consumatori di prodotti pronti al consumo. Le industrie agro-alimentari rispondono a questa richiesta con i prodotti appartenenti alla categoria della IV gamma (detti anche fresh-cut o ready to eat), ossia frutta e verdura fresca, lavata, tagliata, confezionata in packaging personalizzati e posta nei banchi refrigerati della grande distribuzione organizzata (GDO). Nell’ambito del triennio del Dottorato di Ricerca si è scelto di approfondire una dell…
Monitoring the Shelf-Life of Minimally Processed Fresh-Cut Apple Slices By Physical–Chemical Analysis and Electronic Nose
2014
Fresh-cut apples, in slices or in cubes, are minimally processed products, which are currently collecting a great interest by fruit marketers for their promising diffusion. Their shelf life, from a microbiological point of view, has been fixed about 2 or 3 weeks under refrigeration. However in a few days they undergo biochemical degradations with production of off-flavors and texture breakdown. In this work, the change of aromatic fingerprint of apple slices packaged in air and in a modified atmosphere (with 100% N2) and stored at 4°C was measured, by using a commercial electronic nose. The obtained data were also compared with sensory evaluation of judge’s panel. Moreover, quality paramete…
Important varieties of Sicily
2012
Sicily is an island to the south and west of Italy that is close to the “toe of the boot”, in the Mediterranean Sea. Its physical characteristics are representative of the Mediterranean region with its mountainous terrain and volcanoes, rugged coast, numerous beaches and blue water, scenic villages, and a diverse agriculture including wine grapes, citrus, olives, herbs, grains and seasonal vegetables. The climate is warm to hot, and the growing season is long. Located at the 36-38 degree latitude, Sicily is only about 160 kilometers (100 miles) from the north coast of Africa near Tunisia. It is also the midpoint east and west in the Mediterranean Sea. Through history the region was controll…
How a traditional agricultural protection structure acts in conditioning the internal microclimate: a statistical analytical approach to Giardino Pan…
2014
This work aims to analyze the traditional agricultural technique of the Giardino Pantesco, typical of the isle of Pantelleria (Sicily, Italy). With this particular technique a single citrus tree is encircled by a drywall of volcanic rocks allowing it to grow even in the island's unfavorable meteorological conditions. This technique has been analyzed by placing one instrumental array inside the Giardino and one outside and by measuring different environmental variables. The aim of the work is therefore to understand what is the drywall's effect on the tree by analyzing the time series produced by the sensors, using cross-correlation techniques and reducing the series' autocorrelation, so tha…
Survival, morphological variability, and performance of Opuntia ficus-indica in a semi-arid region of India
2022
Cactus pear (Opuntia ficus-indica (L.) Mill.) can survive extreme environmental condition and is known for its fodder potential in many parts of the world. The morphological diversity of 15 introduced accessions was evaluated at Jhansi, Uttar Pradesh, India. The plants were established in 2013. Survival and nutrient status were evaluated after two years. Above-ground plant height, biomass, primary and secondary cladode numbers, primary and secondary cladode lengths and below-ground root length, weight, and surface area measurements were done six years after cladode planting. Yellow San Cono, White Roccapalumba, and Seedless Roccapalumba survived 100%. The discriminant traits according to pr…
Applicazione di Tecniche non distruttive per la valutazione delle proprietà fisico-meccaniche dei frutti
2017
Negli ultimi decenni, la richiesta e il consumo crescente di prodotti alimentari di qualità hanno motivato la ricerca e lo sviluppo di nuove soluzioni tecnologiche in campo agroalimentare. L’applicazione di metodi e sistemi tecnologicamente avanzati ha garantito il raggiungimento, lungo tutta la filiera, di elevati standard di qualità e di sicurezza degli alimenti. In campo ortofrutticolo è di fondamentale importanza, soprattutto nella fase di postraccolta, monitorare lo stato di salute dei prodotti deperibili trasportati poiché diversi fattori influenzano le caratteristiche organolettiche e nutrizionali dei prodotti. Oltre alle tecniche di spettroscopia NIR, il cui utilizzo nel settore nel…
