Apple-products phytochemicals and processing: a review.
2009
Epidemiological studies have linked the consumption of apples with reduced risk of some cancers, cardiovascular disease, asthma, and diabetes. Extensive research exists on apples and the health benefits of their beverages and phytochemicals. The purpose of this paper is to review the most recent literature in this area focusing on phytochemicals, phytochemical bioavailability and antioxidant behavior.
Fruit quality and flavor compounds before and after commercial harvest of the late-ripening ‘Fairtime’ peach cultivar
2007
ABSTRACT In this work quality of tree ripe and commercial ripe ‘Fairtime’ peach fruit was evaluated during fruit maturation and storage. Quality parameters and volatile fraction were monitored at intervals of 7-15 days from pit hardening until 10 days after commercial harvest and after 7, 17 and 24 days of refrigeration. In fruit on the tree, weight increased quadratically, diameter and peel color increased linearly, whereas flesh firmness decreased linearly. Soluble solids (SS) reached maximum levels at commercial harvest, whereas acidity started declining after commercial harvest. In the peel, esters and alcohols showed opposite trends. In the flesh, alcohols decreased quadratically and d…
Shading Net and Partial Covering Plastic Film Do Not Affect Phenology, Photosynthetic Activity or Fruit Quality Traits of Kensington Pride Mango
2022
Mango cultivation in a protected environment is becoming widespread in the Mediterranean basin where the species has to face unfavorable weather conditions which do not occur in its native cultivation areas. Besides open-air cultivation, greenhouses—and other protection systems such as shading nets and partial covering of plastic films—have been tested recently. In this study, we focused on assessing the effect of a shading net, and a partially covering plastic film, on the development of “Kensington Pride” mango fruit skin-color, its final quality, and the plants’ photosynthetic activity. A new method of measuring mango skin-color on different sides of the fru…
Il ruolo delle Tecnologie Informatiche e di Comunicazione e della logistica distributiva sulla competitività del comparto ortofrutticolo siciliano
2012
In recent years, the market globalization process has deeply changed the international competitive background, leading, inevitably, to a revision of the strategies and the organization structures of the companies. It is now widely accepted that Information and Communication Technology (ICT) and supply chain logistics management, have an important role in the increasing of the competitive potential of each company and in the development of entire economic sectors. The importance of these factors in the business strategies of the firms, has generated an increasing attention by the research world to the study of the economic and social impact, both about the spread of modern information and co…
Agricultural externalities and environmental regulation: evaluating good practice in citrus production
2006
Economic activity takes place in a scenario characterized by an increasing number of environmental regulations aimed at bringing under control the emission of contaminating wastes. In this paper, we evaluate the impact of transforming a code of good practice in nitrogen fertilization on Spanish citrus fruit farms into an environmental regulation of compulsory fulfilment. Using data envelopment techniques, we calculate unrestricted and environmentally regulated short-run maximum profits. Both profit values are then used to compute an index of the cost of regulation. Our results suggest that the cost of shifting from a merely recommended practice to a binding rule is low. On average, the loss…
Cactus pear (O. ficus-indica (L.) Mill.) fruit production: Ecophysiology, orchard and fresh-cut fruit management
2015
Cactus pear (Opuntia ficus-indica L. Mill.) is cultivated in wide range of environments with the consequence of large differences in crop potential, orchard systems and management. These differences may be related to temperature and rainfall range (water availability) but also to the day/night length and, of course, to soil characteristics. This leads to considerable variability in the field and in fruit quality. Crop value much depends in crop variability in terms of fruit size, which is the major factor for fruit price in Europe. The increase of crop value very much depends on regular cultural practices such as irrigation and fruit thinning, but it is also dependent on plant crop yield an…

Comparing conventional and organic citrus grower efficiency in Spain
2014
This paper compares the organic and conventional citriculture systems in Spain from the perspective of their technical efficiency. The primary objective of the research is to compare the relative efficiency of these two systems in relation to a metafrontier that envelops both technologies. In addition, the article analyses how efficient each growing system is at using its own technology, that is, when farms’ efficiency is benchmarked in relation to the best practices in their group. Contrary to conventional practice, farms’ performance is analyzed in terms of specific growing tasks: soil and plant cover management, pruning, fertilization and phytosanitary treatments. The results obtained hi…
Evaluation of the original dose in irradiated dried fruit by EPR spectroscopy
2011
Abstract The electron paramagnetic resonance spectroscopy (EPR) is one of the physical methods, recommended by the European Committee for Standardization, for the identification of irradiated food containing cellulose, such as dried fruit. In this work the applicability of EPR as identification method of irradiated pistachios, hazelnuts, peanuts, chestnuts, pumpkin seeds is evaluated; the time stability of the radiation induced signal is studied and the single aliquot additive dose method is used to evaluate the dose in the product.
Analysis of protein composition of red wine in comparison with rosé and white wines by electrophoresis and high-pressure liquid chromatography-mass s…
2009
Wine proteins not only influence wine stability but are also being discussed as potential allergens. Proteins from red, rose, and white wines were enriched by dialysis and lyophilization followed by separation by SDS-PAGE. Significant differences were detected in the protein compositions of the analyzed wine varieties, and the major protein bands were identified by mass spectrometry after in-gel digestion with trypsin. In German Portugieser red wine, a total of 121 tryptic peptides were identified, which were attributed to 12 grape proteins and 6 proteins derived from yeast. Among the identified constituents are several proteins considered to influence wine stability and previously describe…
