On the measured lifetime of light hypernuclei 3ΛH and 4ΛH
2014
A statistical combination of the experimental lifetime estimations available in the literatures is performed for 3 Λ H and 4 Λ H, including several recent measurements. The combined average values of the lifetime for 3 Λ H and 4 Λ H are respectively 216−16+19 ps and 192−18+20 ps with a reduced χ2 of 0.89 and 0.48. A new insight into the lifetime estimation of the HypHI Phase 0 experiment by a Bayesian approach is also presented. In this approach, several different prior distributions including the combination of previous lifetime data and a Jeffrey prior are used. The principal mode and the smallest credible interval at 68% of the posterior distribution, given by the prior belief of the pre…
Evaluation of beauvericin and enniatins in Italian cereal products and multicereal food by liquid chromatography coupled to triple quadrupole mass sp…
2013
In this study, 48 multicereal baby foods samples including 25 of pasta and 23 of multicereal baby foods from supermarkets of Campania region (Italy) were analysed for evaluating the presence of beauvericin (BEA) and enniatins (ENs) A, A1, B, B1 and B4. Subsequently to evaluate the risk exposure of Italian population and infant population over the consumption of pasta or multicereal baby food, was, respectively, evaluated. For the above mentioned evaluation, a method developed in our laboratory by liquid chromatography tandem mass spectrometry was used. A liquid phase dispersion procedure was optimised for the simultaneous extraction of BEA and the five ENs from multicereal baby food samples…

Iron bioavailability in iron-fortified cereal foods: The contribution of in vitro studies
2015
Iron deficiency anemia is the most common nutritional deficiency in humans. Not all dietary ingested iron, heme or nonheme, will be available to absorption and negative imbalance between iron requirements and absorption leads to iron deficiency and/or anemia. The recommended iron values usually are based on the genetic and on diet iron-bioavailability, which can be considered as the principal factor that change among the cultures and influences the distinct levels of recommendation among countries. Dietary changes present practical limitations due to be difficult to change food habits. The iron food fortification is considered more cost effective and economically more attractive than iron s…
The role of mucilage of Opuntia ficus-indica Mill. on sweet cherry fruit during storage
2022
Sweet cherry (Prunus avium L.) is an important crop from temperate areas and is widespread and much appreciated by the consumers when the pedicel is green. The objective of this work was to evaluate the quality of sweet cherry fruit treated with a mucilage coating, extracted from cladodes of Opuntia ficus-indica L. Mill (OFI). The cultivar ‘Ferrovia’ was harvested at the commercial ripeness stage from an orchard in Puglia (Italy), stored for 14 days at 2°C and RH 92% and to evaluated by the variation of color and other qualitative parameters such as physical-chemical, nutraceutical and sensory analysis. Fruits were transferred at 10°C to postharvest laboratory of University of Palermo after…
Use of xanthan gum and calcium ascorbate to prolong cv. Butirra pear slices shelf life during storage
2023
After cut, pear fruit (Pyrus communis L.) during shelf-life can be subjected to colour and flavour changes. To maintain flesh colour and firmness, different technologies could be employed during shelf-life, such as chemical, physical and edible coating treatments. In the present study, the effects of two edible coating formulations containing xanthan gum and calcium ascorbate on fresh-cut pear fruit were investigated. After harvest, 200 fruits were cut and coated with Xanthan Gum (XAN) and distilled water or Xanthan gum + Calcium Ascorbate (ASC), respectively, while control (CTR) pear fruit slices were soaked in distilled water and lastly packed in polyethylene terephthalate (PET) packages …
Qualitative traits and shelf life of fig fruit (cv Melanzana) treated with Aloe vera gel coating
2021
The fig (Ficus carica L.) cv Melanzana is typical of Southern Italy. This cultivar produces breba fruit in June and fig fruit in August. Some previous studies on the use of coatings extracted from stems of Aloe vera showed positive effects to maintain fruit quality during shelf life. However, there are no studies on breba fig fruit treated with Aloe vera coating. In this study breba fig fruit, cv Melanzana, was treated with an application of Aloe vera gel, sealed in macro-perforated bag and stored at 5°C for 10 days. The effect of application of the Aloe vera gel on the shelf-life of this fruit, and its quality attributes after application were evaluated measuring fresh weight, total solubl…
Effetti dell’applicazione di Edible Coating sul comportamento fisiologico e sulle caratteristiche fisico-chimiche, nutrizionali e sensoriali in prodo…
2021
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…
Effects of xanthan gum and calcium ascorbate treatments on color and nutritional quality of fresh cut pear fruit
2023
Edible coatings may be used to extend the shelf life of fresh-cut fruit products by controlling respiration and transpiration reducing overall quality decay. In this study, the effects of xanthan gum, combined with calcium ascorbate treatment, on color and nutritional quality of fresh-cut pear fruit were investigated. Fresh-cut pear fruit were processed with dipping for 4 different treatments: 2% xanthan gum solution with 2% calcium ascorbate (XAC); 2% xanthan gum solution (XAN); 2% ascorbate calcium solution (CAL) and distilled water for control (CTR). Fruit treated were stored at 5°C for 3, 5, 7 and 10 days. At each storage period, visual quality and flavor score, ascorbic acid and phenol…
Development and application of a new Edible Coating on fruits and fresh-cut fruits.
2014
Il progetto di ricerca ha come scopo il miglioramento della gestione post-raccolta dei frutti (interi e di IV gamma), intervenendo sull’estensione della shelf-life; valutando l’utilizzo di composti provenienti da materiali di scarto delle filiere produttive agroalimentari o risorse alternative da utilizzare come nuovi rivestimenti commestibili (edible coating: EC). La novità riguarda lo sviluppo di un edible coating a partire da residui vegetali di Posidonia oceanica, pianta acquatica mediterranea ampiamente diffusa sulle coste siciliane, responsabile di accumulo di biomassa sulle spiagge. Per soddisfare, in maniera efficace, l’obiettivo iniziale si vorrebbe creare una interazione tra 1-MCP…
