IL POTENZIALE FITOALIMURGICO DI INTERESSE ORTICOLO DELLA FLORA SICULA: Osservazioni sull’autoecologia di alcune specie eduli appartenenti alle famiglie delle Liliaceae, Brassicaceae, Orchidaceae e Boraginaceae.
No full textL’indirizzo dato dall’U.E. verso settori produttivi inesplorati e di qualità, mette in risalto la rilevante potenzialità che la fitoalimurgia potrebbe avere nel settore agricolo. Tale requisito è legato al ruolo che le erbe eduli potrebbero esercitare nella filiera agro-alimentare, tenuto conto della richiesta di specie erbacee native nella dietologia, nell’omeopatia, nell’erboristeria, e nella tipizzazione della ristorazione agrituristica. Poiché l’aleatorietà dell’offerta legata alla raccolta in natura è ostativa alla loro valorizzazione, si è ritenuto opportuno studiare la tassonomia e l’autoecologia di alcune specie di maggiore interesse orticolo, con la finalità di dare un contributo alla definizione del loro valore bio-agronomico per il passaggio dalla fitoalimurgia all’agro-fitoalimurgia
Citrus History, Taxonomy, Breeding, and Fruit Quality
No full textIn May, every year since 1857, in the great park of Sans-Souci in Potsdam just outside Berlin—a park begun in 1745 by Emperor Frederick II of Hohenzollern and expanded a century later by Frederick William IV—the doors of the great Orangerie open in and a Renaissance-style garden called Sizilianischer Garten is set up. On horse-drawn carriages,large olive and citrus trees are brought outdoors, and are then raised in masters. For the young European who, in the second half of the 18th century and in the first decades of the following, traveled to Italy to see and study Renaissance culture and the remains of Greek civilization, the citrus species and fruits and groves of southern Italy became the ultimate symbol of beauty and a sort of status symbol of wealth, particularly that of landowners. Nothing is more expressive of the fascination of their fruit than Abu-l- Hasan Ali’s 12th-century writings: “Come on, enjoy your harvested orange: happiness is present when it is present. / Welcome the cheeks of the branches, and welcome the stars of the trees! / It seems that the sky has lavished gold and that the earth has formed some shiny spheres.” Indeed, Citrus spp. are among the most important crops and consumed fruit worldwide. Their co-evolution due to a millennial agricultural utilization resulted in a complexity of species and cultivated varieties derived by natural or induced mutations, crossing and breeding the “original” species (Citrus medica, Citrus maxima, Citrus reticulate, Fortunella japonica) and their main progenies (C. aurantium, C. sinensis, Citrus limon, Citrus paradisi, Citrus clementina, etc.). Citrus spread from the original tropical and subtropical regions
of southeast Asia toward the Mediterranean countries of Europe and North Africa and, after 1492, in the Americas, not to mention South Africa and Australia, where they still have a very important role. Citrus species, wherever they have been cultivated, quickly became the protagonists of the letters and the arts, as well as the markets and gastronomy, and can even be found in religious ceremonies, such as for Feast of Tabernacles (Sukkot). Studies on Citrus botany, cultivation, and utilization have been pursued since the early stages of the fruit’s domestication and grew following their introduction in
Europe, the Americas, Africa, and Australia. Citrus research involves many different aspects: such as the study of citrus origin and botanical classification; citrus growing, prop agation, and orchard management; citrus fruit quality, utilization and industry; citrus gardening and ornamentals; citrus in arts and manufacturing
Il suolo, bene comune
No full textIl disegno di legge in materia di "valorizzazione delle aree agricole e contenimento del consumo di suolo", approvato dal Consiglio dei ministri il 14 settembre 2012, ha evidenziato la necessità di attivare politiche nazionali per ridurre gli usi non efficienti dei suoli agricoli. Serve però una misura delle variazioni nell'uso dei suoli che risponda a una serie di requisiti essenziali: dati di base adeguati per risoluzione geometrica; modalità uniformi di classificazione degli usi/coperture; metodologie di rappresentazione delle variazioni d'uso scientificamente fondate; informazioni scalabili e interoperabili a ogni livello di governo; periodicità di aggiornamento e copertura alla scala nazionale. Su questa base, si possono (e si devono) fondare politiche che mirino da subito ad annullare gli usi inefficienti e in prospettiva a conseguire un "bilancio zero" tra nuovi usi ed effettive rigenerazioni, agendo sulle determinanti e non sugli esiti del fenomeno. Ciò impone un rafforzamento della tenuta economica delle aree agricole, soggette a fenomeni di abbandono oltre che alla pressione dell'urbanizzazione: per questo serve un riconoscimento, ove ne ricorrano le condizioni, dei benefici pubblici generati dalle attività agricole e un contestuale sviluppo dei percorsi imprenditoriali che mirano alla crescita del valore aggiunto aziendale, sia agricolo che extra-agricolo
Ficodindia
No full textLo studio degli alberi e la scienza delle coltivazioni distinguono un’Arboricoltura generale da un’altra speciale. Classificazione dottrinaria, questa, ormai consolidata. Pur essendo entrambe dettate dagli stessi principi teorici, trattano in modo complementare ed integrato le modalità tecniche delle loro applicazioni pratiche. Il volume Arboricoltura speciale, pubblicato da Edagricole, colma finalmente un’esigenza molto sentita dal mondo accademico e dal sistema mediatico di informazione pubblica, di crescente importanza, sempre più attento al recupero delle funzioni degli alberi nel mondo in cui viviamo ficus-indica L. (Mill.) (OFI), comunemente nota come ficodindia, appartiene alla famiglia delle Cactaceae, sottofamiglia delle Opuntioideae, che contiene circa 130 generi e quasi 1.500 specie, tutte originarie del Continente americano. L’Opuntia ficus-indica, in particolare, è una specie originaria degli altopiani del Messico centrale
Introduction: The Impact of the COVID-19 Pandemic on the Agri-food Supply Chain
No full textThe origin of the COVID-19 pandemic is still unclear, but the link with the presence in the food chain of wild animals for human consumption has been claimed as one of the possible sources of the so-called “spillover” of the virus. Food safety throughout the food chain, from field to fork, is one of the most critical issues of the food industry, and significant differences still exist from country to country concerning food production systems, postharvest management, trading, and retail organization. The effect of the pandemic has touched all steps of the food chain
Shelf-life and quality of fresh-cut peach Cv 'Ruby Rich' at different maturity stage
No full text'Ruby Rich' is a yellow-flesh peach cultivar that ripens during the last week of May and the first of June. This fruit is characterized by distinct colour and size, which make it highly appreciated by consumers, particularly, in the local markets. However, is known about 'Ruby Rich' minimal processing physiology. The aim of this study was to investigate the effect of passive atmosphere, during 12 d, on shelf-life and quality of fresh cut peach fruit, at different ripening stages. 'Ruby Rich' peach fruits were picked at mature-green stage (MG) (55.0 ± 0.5 N), and ripe stage (RP) (35.7 ± 0.7 N) determined by flesh firmness. Fruits were washed, peeled, sliced and stored for 0, 3, 5, 7 and 12 days after cut, six replications were used for each storage time. Scores of appearance and firmness, weight, colour, respiration rate, soluble solids total, ascorbic acid and phenols were observed. Significant differences occurred on MG treatment in terms of visual quality, flesh firmness, polyphenols and ascorbic acid. Results shows that peach slices (RP) maintain the shelf life condition for 5 d. at 5 °C with the best results in terms of solid soluble content and flavour
Effects of Modified Atmosphere Packaging and Chitosan Treatment on Quality and Sensorial Parameters of Minimally Processed cv. ‘Italia’ Table Grapes
Full text linkTable grape is a non‐climacteric fruit, very sensitive to water loss and gray mold during
postharvest handling and storage. The aim of this work was to evaluate the effects of modified atmosphere
packaging and chitosan treatment on quality and sensorial parameters of minimally processed
cv. ‘Italia’ table grape during cold storage (14 days at 5 °C) and shelf‐life (7 and 14 days of
cold storage plus 5 days at 20 °C), reproducing a retail sales condition. Our data showed a significant
effect of high CO2‐modified atmosphere in combination with chitosan and alone on preserving quality,
sensorial parameters, and delaying decay of minimally processed table grape. The most effective
treatment in terms of preservation of quality, sensory, and nutritional quality was high‐CO2 modified
atmosphere packaging plus chitosan treatment. The overall results showed that when a proper
modified atmosphere packaging is combined with a postharvest chitosan treatment, gray mold
growth can effectively be controlled in ready‐to‐eat cv. ‘Italia’ table grape and that modified atmosphere
packaging (MAP) with high levels of CO2 and reduced concentration of O2 in combination
with chitosan treatment could prevent the negative effect of high‐CO2 in‐packages level, like berry
browning and rachis browning and dehydration
Effects of Argon-Based and Nitrogen-Based Modified Atmosphere Packaging Technology on the Quality of Pomegranate (Punica granatum L. cv. Wonderful) Arils
Full text linkReady-to-eat pomegranate arils are considered a “functional food” for their health benefits and have desirable sensory characteristics, which have caused an increasing interest by the consumers for this product. The preparation process of ready-to-eat fruit products can cause severe injuries and worsen their quality and shelf life significantly. Modified atmosphere packaging (MAP) has been
used broadly in the last years to maintain the quality of processed fruits and showed optimal results, in spite of the possible problems caused by the depletion of O2 and corresponding accumulation of CO2 in the package. This study was conducted to evaluate the effects of different MAP treatments,
based on nitrogen or alternatively on a noble gas, argon, in combination with refrigerated storage (0, 4, 8, 12, and 16 days at 4 1 C and 90 5% RH) on the qualitative parameters of pomegranate arils with the aim to prolong their post-harvest life maintaining the original quality. The argon-based MAP treatment (MAPAr) was the one that provided the best results, assuring a limited loss of weight and juice content. The use of noble gas allowed to maintain a high sugar/acid ratio until 16 days from packaging. Sensory analysis on all MAP treated arils and, on the juice, obtained from them were carried out, and judges showed a preference for MAPAr treated arils and juice until day 12 from packaging
Pomegranate Cultivation in Mediterranean Climate: Plant Adaptation and Fruit Quality of ‘Mollar de Elche’ and ‘Wonderful’ Cultivars
Full text linkTwo pomegranate cultivars, Mollar de Elche, native to Spain, and Wonderful, the most widely cultivated pomegranate variety in the world, were studied in a commercial orchard in Sicily, and their phenological behavior was compared. During the development of the fruit, their dimensional growth was monitored, and after harvest, physicochemical and sensory analyses were carried out to highlight the differences between fruit of the two cultivars. Results showed that Mollar de Elche fruit require less time from flowering to fruit maturity, resulting in an earlier harvest, which was due also to a higher relative growth rate of the fruit’s diameters. On the other hand, physicochemical analyses confirmed that Wonderful is the variety that is most appealing for fresh produce consumers due to its intense coloring. However, Mollar de Elche showed economically desirable characteristics such as a good softness of the seed. Moreover, sensory analysis showed that fruit of the cv. Mollar de Elche was found to have a sweeter taste of both arils and juic
