Extension of Tosela cheese shelf-life using non-starter lactic acid bacteria
2011
Six strains of non-starter lactic acid bacteria (NSLAB) were used to extend the shelf-life of the fresh cheese Tosèla manufactured with pasteurised cows’ milk. The acidification kinetics of three Lactobacillus paracasei, one Lactobacillus rhamnosus and two Streptococcus macedonicus were studied in synthetic milk medium. Lb. paracasei NdP78 and NdP88 and S. macedonicus NdP1 and PB14-1 showed an interesting acidifying capacity and were further characterised for growth in UHT milk and production of antimicrobial compounds. Lb. paracasei NdP78 and S. macedonicus NdP1 grew more than 2 log cycles in 6 h. Lb. paracasei NdP78 was also found to produce a bacteriocin-like inhibitory substance (BLIS) …
Extracts deriving from olive mill waste water and their effects on the liver of the goldfish Carassius auratus fed with hypercholesterolemic diet
2014
The present research aims to evaluate the beneficial effects of polyphenols derived from waste water from a olive mill, obtained by non-plastic molecular imprinting device, in a hypercholesterolemic diet on Carassius auratus, commonly known as goldfish that was selected as experimental model. The study was conducted with morphological and histochemical analyses and also the data were supported by immunohistochemical analysis. Results show the beneficial activity of polyphenols with a reduction of the damage in the steatotic group, confirming that they may be suggested in the treatment of diseases by lipid accumulation, and used as any addition in feed for farmed fish, in order to improve th…
Antioxidant activity and phenolic composition in Pomegranate (Punica granatum, L.) genotypes from south Italy by UHPLC/Orbitrap-MS approach
2018
Background: Pomegranate fruits are a rich source of polyphenols with numerous health-promoting effects. Pomegranate juices of five genotypes (‘Mollar’, ‘Kingdom’, ‘Dente di Cavallo’, and two old populations ‘Francofonte’ and ‘Santa Tecla’) were evaluated regarding anthocyanin and non-anthocyanin phenolic contents using ultrahigh performance liquid chromatography (UHPLC)–Orbitrap-mass spectrometry (MS). Moreover, total antioxidant activity (TAA) was evaluated using a 2,2′-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS) assay. Results: Twenty-three phenolic compounds were identified. Cyanidin-3,5-O-diglucoside and pelargonidin-3,5-O-diglucoside were the most representa…
Food quality and nutraceutical value of nine cultivars of mango (Mangifera indica L.) fruits grown in Mediterranean subtropical environment
2019
Mango (Mangifera indica L.) quality is strongly influenced by genotype but individuating the most appropriate harvesting time is essential to obtain high quality fruits. In this trial we studied the influences of the ripening stage at harvest (mature-ripe or green-ripe) on quality of ready to eat mango fruits from nine cultivars (Carrie, Keitt, Glenn, Manzanillo, Maya, Rosa, Osteen, Tommy Atkins and Kensington Pride) grown in the Mediterranean subtropical climate through physicochemical, nutraceutical, and sensory analysis. Our results show a large variability among the different observed genotypes and in dependence of the ripening stage at harvest. With the exception of Rosa, mature-ripe f…

Germplasm evaluation to obtain inulin with high degree of polymerization in Mediterranean environment
2020
Long-chain length (DP) inulin-type fructans show pronounced beneficial effects to colon microbiota. In the past, cardoon roots for inulin production to fortify spaghetti gave very good results, but their harvest requires high costs. The aim of the work was to evaluate different types of inulin, extracted from cardoon roots and buds, topinambur tubers and chicory roots local populations in order to identify crops more suitable for high DP inulin production in Mediterranean environment. The inulin amount resulted in 115 (chicory), 390 (cardoon) and 550 g kg−1 of d.m. (topinambur). Both in cardoon roots and in topinambur tubers the DP was very high. With the aim to produce a functional food, s…
PRELIMINARY STUDY OF “NERO D'AVOLA” CULTIVAR FROM MUST TO WINE BY SPME-GC/MS ANALYSIS

PARTE IV - Impresa agricola e sistema agroalimentare. Capitolo II, 2.1. I regimi della produzione
2023
Questo volume nasce dalla necessità di offrire una lettura contemporanea delle peculiari regole che tradizionalmente hanno attribuito al Diritto agrario un carattere di specialità. Facciamo riferimento alle norme che in un’ottica di programmazione di un settore produttivo centrale per l’economia del nostro paese disciplinano l’impresa agricola, la proprietà terriera, i contratti agrari, il lavoro agricolo, il credito agrario, il mercato dei prodotti agricoli. Regole la cui chiave di lettura è sempre passata dalla considerazione dell’esistenza di un legame stretto tra “agricoltura” e “terra”, considerazione che non riteniamo superata, ma piuttosto aggiornata, dalle numerose innovazioni legis…

Questo volume nasce dalla necessità di offrire una lettura aggiornata, contemporanea appunto, delle peculiari regole che tradizionalmente han- no attribuito al Diritto agrario un carattere di specialità.

Determination of Aflatoxins and Ochratoxins in Sicilian Sweet Wines by High-Performance Liquid Chromatography with Fluorometric Detection and Immunoa…
2015
Ochratoxin A is the only mycotoxins with legal limits in the European Union for wine, by contrast, there is no EU legislation imposed for Aflatoxins and Ochratoxin B. A reproducible and sensitive analytical method for six mycotoxins: Ochratoxin A, Ochratoxin B, Aflatoxins B1, Aflatoxin B2, Aflatoxin G1 and Aflatoxin G2 was developed by using immunoaffinity column cleanup and HPLC-FLD method in 30 sweet wines produced in Sicily. This typical type of wine is manufactured from grapes grown in warmer climates, which have a higher sugar content; also, the over-ripening and the drying process of the grapes before fermentation conditions are responsible for the particular susceptibility of these b…
