The Quality of Five Natural, Historical Italian Cheeses Produced in Different Months: Gross Composition, Fat-Soluble Vitamins, Fatty Acids, Total Phe…

2022

Simple Summary For the purposes of raising awareness of five historical cheeses of Southern Italy that are less known by consumers, and of restoring dignity to the breeders and producers of these cheeses, we studied their quality in terms of chemical composition, monounsaturated fatty acid (MUFA), polyunsaturated fatty acid (PUFA), conjugated linoleic acid (CLA), PUFA-ω6, PUFA-ω3, α-tocopherol, retinol, cholesterol, polyphenol content (TPC), total antioxidant capacity (FRAP and TEAC), and health index (GHIC). Two stretched-curd bovine cheeses, Caciocavallo Palermitano (CP) and Casizolu del Montiferru (CdM), two ovine cheeses, Vastedda della Valle del Belìce (VVB) and Pecorino Siciliano (PS)…

Agricoltura di qualità e rete natura 2000: “laboratori” del cambiamento

2011

Through the centuries, rural communities have managed their environment creating a rich landscape diversity. This represents an historical heritage both for the region and for humanity because the "world" itself represents the sum of widespread fragmentation processes following specific laws. The intense socio-economic changes of the last century, the rise of the "global" markets, in particular, have radically changed the landscape configuration and its natural quality across Europe. Natura 2000 network and the network of protected areas are currently the "open laboratories" to test a model of development that is compatible with the priceless treasure such as: species, habitats, landscape a…

Nutritional epigenomic and DNA-damage modulation effect of natural stilbenoids

2023

The aim of the present work is the evaluation of biological effects of natural stilbenoids found in Vitis vinifera, with a focus on their activity as epigenetic modulators. In the present study, resveratrol, pterostilbene and for the first time their dimers (±)-trans-δ-viniferin, (±)-trans-pterostilbene dehydrodimer were evaluated in Caco-2 and HepG-2 cell lines as potential epigenetic modulators. Stilbenoids were added in a Caco-2 cell culture as a model of the intestinal epithelial barrier and in the HepG-2 as a model of hepatic environment, to verify their dose-dependent toxicity, ability to interact with DNA, and epigenomic action. Resveratrol, pterostilbene, and (±)-trans-pterostilbene…

Opuntia cladodes as functional ingredient in durum wheat bread: rheological, sensory, and chemical characterization

2021

Cladodes are considered by-products of Opuntia ficus-indica cultivation. Their addition as source of antioxidants to durum wheat breads could have effects on preventing cardiovascular diseases, cancers, and inflammation. The inclusion of 0-5-10-15% cladodes, harvested in three different locations, on quality and antioxidant properties of fortified durum wheat breads has been evaluated. The enrichment with 10% of cladodes resulted in an increase in the content of total phenolics (14.8 vs 2.7 mg GAE/100 g of control bread), a decrease of IC50 (3.28 vs 49.7 mg/ml of control bread), good rheological characteristics of loaves and largely positive evaluation by panel test. Fortification with 15% …

Determination of terpene alcohols in Sicilian Muscat wines by HS-SPME-GC-MS.

2013

Muscat is a grape family used to obtain several sweet, aromatic white dessert wines common in the Mediterranean area. Currently, three Sicilian cultivars (all classified DOC) are known: 'Moscato di Siracusa' the oldest and very rare today; 'Moscato di Noto', a modern derivative of the first and finally 'Moscato di Pantelleria', now the most common. This study concerns the volatile profile of 15 different Sicilian Muscat wines produced in different years using HS-SPME-GC-MS. In particular, four fundamental terpene alcohols (linalool, geraniol, nerol and citronellol) were considered. The principal aim was to study the evolution of aromatic compounds in wine during aging, and the information o…

Food Contaminants

2014

Chemical contaminants may occur in our food from various sources. Contaminants can be present in foods mainly as a result of the use of agrochemicals, such as residues of pesticides and veterinary drugs, contamination from environmental sources (water, air or soil pollution), cross-contamination or formation during food processing, migration from food packaging materials, presence or contamination by natural toxins or use of unapproved food additives and adulterants. They typically pose a health concern, resulting in strict regulations of their levels by national governments and internationally. Therefore, analysis of relevant chemical contaminants is an essential part of food safety testin…
