Seasonal characterization of nutritional, technological and antioxidant properties of Opuntia ficus-indica Mill. mucilage

2022

Opuntia ficus-indica Mill. fruit and cladodes are a source of mucilage, a carbohydrate complex, as well as of phytochemicals and other nutrients, useful in the food industry. Despite the environmental-based composition variability studied, there is no information on its seasonal variability, which is particularly important for its industrial use. In this study, some technological, nutritional, and bioactive properties of O. ficus-indica Mill. cladodes mucilage were analysed during the seasonal growth period. Total proteins did not change during the whole period and the lipid content significantly decreased from winter to the onset of summer. The fatty acid profile showed high levels of palm…

Fast field Cycling NMR for quality characterization of typical sicilian honeys.

2009

Proton NMR relaxometry with fast field cycling (FFC-NMR) setup is developing as a very promising tool for the characterization of agro-food matrices. In fact, some papers have been published reporting on differences among balsamic vinegars, porous properties of oil-water emulsions and quality of meat-products. In the present study, quality of some typical Sicilian honey samples has been evaluated by traditional wet-chemical analyses and FFC-NMR. Nine wet-chemical parameters have been measured such as water content, pH, acidity (free, lactonic and total acidity), fructose, glucose, saccharose, electrical conductivity, diastase activity and colour. Results showed that 84% of the samples were …

L'incremento della sostenibilità ambientale attraverso una corretta gestione dell'irrigazione.

2014

Lo scopo di questo lavoro è quello di mettere a punto, a partire dalle informazioni territoriali quali caratteristichemeteorologiche e pedologiche, uno studio capace di valutare la sostenibilità della gestione irrigua in tre ipotetiche parcelle sperimentali individuate nel territorio del sottobacino Iudeo-Bucari (TP). Sitratta di tre vigneti che rappresentano per caratteristiche morfologiche e gestionali l'intero sottobacino, ovvero una delle aree maggiormente vitate della Sicilia. Il fine è valutare la sostenibilità della gestione irrigua in termini di risparmio energetico, attraverso l'applicazione del modello di bilancio idrico FAO 56. Questo tipo di studio pone le basi per la redazione …

Genetic characterization of the Mascaruna goat, a Sicilian autochthonous population, using molecular markers

2013

The aim of this work was to characterize a Sicilian autochthonous goat population using microsatellite markers and genetic polymorphisms at the casein genes. In order to investigate the genetic structure of the Mascaruna goat, a total of 60 (20 Girgentana, 20 mixed populations, and 20 Mascaruna) individuals were analyzed, using a panel of 18 microsatellite markers. Moreover, the Mascaruna goats were genotyped at casein loci using several molecular techniques. Based on the genetic structure at casein genes, the Mascaruna goat was similar to most goat breeds from the Mediterranean area, which are characterized by the predominance of strong alleles. The low value of genetic differentiation amo…

The effects of the traditional producing system on physicochemical, microbial and sensory properties of Caciocavallo Palermitano cheese

2015

Caciocavallo Palermitano (CP) is a traditional cheese made with raw milk from cows of Sicilian local breeds fed pasture-based diets in extensive farms (EXT), processed by an artisanal technology (ART) based on wooden tools and the action of native microflora. CP is obtained also in intensive farms (INT) where milk from cows of specialized breeds fed dry diets is transformed by advanced procedures (ADV) using a stainless steel equipment and lactic acid starter cultures. This research was planned to investigate the changes in cheese properties due to production system and ripening., Milk was collected 3 times from an EXT and an INT farm and processed in ART and ADV conditions. The 12 produced…

Molecular characterization of dominant bacterial population in “Vastedda della Valle del Belice” cheese: preliminary investigation

2010

The sensory characteristics of raw-milk cheeses are linked to the cheese-making process, to the environmental factors as animal feeding and to the biochemical and microbiological composition of the milk. In this report we temped to characterize the microflora in the typical Sicilian historical cheese as Vastedda della valle del Belice. Each cheese was previous subjected to microbial isolation on specific media (M17 and MRS). The colony obtained on the solid medium were subject to biochemical tests and DNA extraction. The microbial diversity occurring in the strains was evaluated by PCR, RFLP and sequencing targeted on 16S ribosomal DNA. A number of closest relatives species of lactic and co…

A Mediterranean record of Eulalia ornata (Annelida: Phyllodocidae) corroborating its fidelity link with the Sabellaria alveolata-reef habitat

2015

Among marine habitats Sabellaria alveolata -reefs deserve protection since they provide important ecosystem services and positive effects on biodiversity. Several marine species are listed among the S. alveolata -reef associated fauna, but characteristic species were seldom reported. Eulalia ornata (Annelida, Phyllodocidae) might represent an exception, since it appears common/abundant in S. alveolata -reefs of the Eastern Atlantic. The most evident geographical mismatch in the distributions of E. ornata and these biogenic reefs occurs in the Mediterranean Sea, where S. alveolata -reefs are commonly found, but E. ornata was never recorded, whilst E. viridis , a non-Mediterranean species, wa…
