The Sicilian peach (Prunus persica L. Batsch) germplasm: Horticultural characteristics and sanitary status

2006

ANTIOXIDANT COMPOUNDS AND QUALITATIVE TRAITS IN EUROPEAN (PRUNUS DOMESTICA L.) AND JAPANESE (P. TRIFLORA L.) PLUM FRUITS AS AFFECTED BY COLD STORAGE

2010

The Italian territory is rich in fruit trees germplasm and in the last years many research programs have been carried out to characterize local cultivars and accessions for deepenings about them and enhancing the market agreement too. The Sicilian plum cultivars 'Sanacore' and 'Ariddo di core' and the Piedmontese plum cultivar 'Ramassin' were studied to highlight their qualitative traits including the nutraceutical properties. Moreover, since it is important to know in which way the qualitative parameters change during the storage period one more study was carried out by storing the fruits under modified atmosphere in the Tectrol ® system. The results evidenced very interesting aspects abou…

Relevance of Interactions between Starch-based Coatings and Plum Fruit Surfaces: A Physical-Chemical Analysis

2019

In order to extend the shelf life of the fruit, improve appearance, and to keep all nutrition properties of the plum from diminishing, edible coatings comprised of wheat starch and wheat starch&ndash

Modeling of the process of moisture loss during the storage of dried apricots

2011

[EN] Moisture content is a reference parameter for dried food because the growth of most microorganisms is inhibited below certain water activity levels. In addition, it has a determining influence on the evolution of important parameters, such as color and flavor, and on other properties and deterioration reactions, such as texture, oxidation processes and nutritional value. During the storage of some dried fruits, moisture is produced due to Maillard reactions and exchanged with the surrounding environment through the packaging. The evolution of dried foods during their shelf life depends on the storage conditions. The aim of this study is to analyze the evolution of the moisture content …

Revalorization of Almond By-Products for the Design of Novel Functional Foods: An Updated Review

2021

The search for waste minimization and the valorization of by-products are key to good management and improved sustainability in the food industry. The great production of almonds, based on their high nutritional value as food, especially almond kernels, generates tons of waste yearly. The remaining parts (skin, shell, hulls, etc.) are still little explored, even though they have been used as fuel by burning or as livestock feed. The interest in these by-products has been increasing, as they possess beneficial properties, caused by the presence of different bioactive compounds, and can be used as promising sources of new ingredients for the food, cosmetic and pharmaceutical industry. Additio…

Major and trace elements in Boletus aereus and Clitopilus prunulus growing on volcanic and sedimentary soils of Sicily (Italy)

2017

The aim of this study was to determine and compare the content of 28 elements (Ag, Al, As, Ba, Be, Bi, Ca, Cd, Co, Cr, Cu, Fe, K, Li, Mg, Mn, Mo, Na, Ni, Pb, Rb, Sb, Se, Sr, Tl, U, V and Zn) in fruiting bodies of Boletus aereus Bull. and Clitopilus prunulus P. Kumm collected from eleven unpolluted sites of Sicily (Italy) and, also to relate the abundance of chemical elements in soil with their concentration in mushrooms. Median concentrations of the most abundant elements in Boletus aereus ranged from 31,290 μg/g (K) to 107 μg/g (Zn) in caps and from 24,009 μg/g (K) to 57 μg/g (Zn) in stalks with the following abundance order: K > Na > Ca > Mg > Fe > Al > Rb > Zn. The s…

Mi.P.A.F. targeted project for evaluation of European and Japanese plum rootstocks in Italy: Results of six years of observations

2007

The Mi.P.A.F. (Italian Ministry of Agriculture) targeted project "National Lists of Recommended Rootstocks and Cultivars", coordinated by Prof. F. Loreti, University of Pisa, aims at evaluating the performance of fruit rootstocks introduced into the Italian nursery market. As part of this project, trials were established to compare some of the most interesting rootstocks for European and Japanese plum in 9 different locations in Italy. The rootstocks tested were: 'Citation-Zaipime', 'GF 31', 'Marianna GF 8/1', 'Ishtara-Ferciana', 'Jaspi-Fereley', 'Julior-Ferdor', 'Myrobalan 29C', 'Myrobalan B', 'MrS 2/5' and 'Myrocal'. In 1995, nine orchards were planted at 5 × 5 m spacing; in each orchard,…

Plant virus cell-to-cell movement is not dependent on the transmembrane disposition of its movement protein

2009

ABSTRACT The cell-to-cell transport of plant viruses depends on one or more virus-encoded movement proteins (MPs). Some MPs are integral membrane proteins that interact with the membrane of the endoplasmic reticulum, but a detailed understanding of the interaction between MPs and biological membranes has been lacking. The cell-to-cell movement of the Prunus necrotic ringspot virus (PNRSV) is facilitated by a single MP of the 30K superfamily. Here, using a myriad of biochemical and biophysical approaches, we show that the PNRSV MP contains only one hydrophobic region (HR) that interacts with the membrane interface, as opposed to being a transmembrane protein. We also show that a proline resi…

Physical pre-treatment of plums (Prunus domestica). Part 1. Modelling the kinetics of drying

2002

An alternative physical method for enhancing the drying rate of plums is proposed. It consists of the superficial abrasion of the plums' peel using an inert abrasive material to remove the cuticular waxy layer, the limiting factor for moisture loss. The physical pre-treatment was compared with a chemical treatment in which the plums were dipped into a solution of ethyl oleate. The drying kinetics of the above samples, including the untreated one, were reconstructed by using a mathematical model. The drying process, carried out at 60 C to reduce the prunes' quality loss, showed the great capability of both pre-treatments to enhance water diffusivity in the plum peel with respect to the untre…

Responses of Prunus ferganensis, Prunus persica and two interspecific hybrids to moderate drought stress

2003

Prunus ferganensis (Kost. & Riab) Kov. & Kost, a close relative of the cultivated peach (Prunus persica (L.) Batsch.), is native to arid regions of central Asia and may possess traits valuable for improving drought tolerance of commercial peach varieties. One distinguishing feature of P. ferganensis is its prominent, elongated, unbranched leaf venation pattern, which behaves as a simple recessive trait in segregating populations of P. ferganensis x P. persica hybrids. To understand whether this trait could be used as a marker in breeding for drought tolerance, we investigated the association between leaf morphological and physiological parameters related to drought response in P. ferganensi…
