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…

An Investigation of the Shelf-life of PDO Vastedda della Valle del Belice Cheese Subjected to Different Packaging Systems Alternative to Vacuum

2015

The aim of this study was to evaluate the effect of different packaging systems alternatives to vacuum that is commonly applied for PDO Vastedda della Valle del Belice (VdB) cheese, a tipical pasta filata cheese, made with raw ewes’ milk. After production following the traditional cheesemaking protocol, VdB cheeses were packaged as follows: vacuum, paraffin wax and two different Modified Atmosphere Packaging (MAP) consisting of a gas mixture of 70% CO2-30% N2 (MAP1) and 100% N2 (MAP2). Cheeses were stored at 4°C and analyzed (25 g) at time 0 and after 15, 30, 60, 90, 120 and 180 days. All the samples were subjected to microbiological analyses for the evaluation of total mesophilic aerobic b…

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…

Caciocavallo Palermitano

2016

The discovery of cheese is a narrative at least 8,000 years old, dating back to the Neolithic era. Yet, after all of these thousands of years we are still finding new ways to combine the same four basic ingredients - milk, bacteria, salt, and enzymes - into new and exciting products with vastly different shapes, sizes, and colors, and equally complex and varied tastes, textures, and, yes, aromas. In fact, after a long period of industrialized, processed, and standardized cheese, cheesemakers, cheesemongers, affineurs, and most of all consumers are rediscovering the endless variety of cheeses across cultures. The Oxford Companion to Cheese is the first major reference work dedicated to chees…

Effect of the pasture, in different seasons, and of the ripening time on the Caciocavallo Palermitano cheese

2008

The Caciocavallo Palermitano cheese is made processing Cinisara cow milk, which shows very interesting qualitative characteristics (Bonanno et al., 2004). The aim of this research was to study the effect of the pasture, in different seasons, and of different ripening on the yield in cheese after 24 h and on the chemical composition of the Caciocavallo Palermitano cheese

Feed intake, milk composition and cheesemaking properties in Girgentana grazing goats with different genotype at αs1-casein and K-casein

2009

Milk ability for cheese manufacturing depends on both animals utilization of dietary nutrients and genetic polymorphism of caseins. It is well known that strong alleles associated with high content of as1-casein increase cheese-making properties of goat milk, whereas there is little information about effect of genetic variants of κ-casein. The aim of this experiment was to investigate the effect of some composite as1-casein and κ-casein genotypes n changing feeding behavior at pasture and milk yield and properties of Girgentana goats. Forty goats were genotyped at as1, as2, b and κ-casein loci using specific PCR protocols at DNA level and IEF technique at milk protein level. Twelve goats, d…

Influence of Citrus Essential Oils on the Microbiological, Physicochemical and Antioxidant Properties of Primosale Cheese

2022

The aim of this study was to produce a fresh ovine pressed cheese within Pecorino “Primosale” typology with the addition of citrus essential oils (EOs). For this purpose, ewe’s pasteurized milk was added with EOs from the peel of lemons, oranges and tangerines. Seven cheese productions were performed at the pilot plant scale level, including one control production (CP) without the addition of EOs and six experimental productions obtained by the addition of two EO concentrations (100 and 200 µL/L) to milk. The acidification process was obtained by means of the starter cultures Lactococcus lactis CAG4 and PON36. All cheeses showed levels of lactic acid bacteria (LAB) a…

BATTERI LATTICI CON ATTIVITA’ ANTIBATTERICA ISOLATI DA FORMAGGI TRADIZIONALI SICILIANI

2013

The study was conducted on typical Sicilian cheeses made from raw cow milk (Caciocavallo Palermitano) and sheep milk (Vastedda della valle del Belice PDO e Pecorino PDO). Genotypic identification of the LAB isolates was carried out by 16S/23S rRNA sequencing. a total of 400 bacteria strains were isolated and genotypically identified as Lactobacillus spp., Lactoccoccus spp., Pediococcus spp., Leuconostoc spp., Enterococcus spp. and Streptococcus spp. Evaluation of bacteriocin-producing LAB was investigated in vitro using the “spot on the lawn” method (2) aganist Listeria monocytogenes, Staphylococcus aureus, Salmonella enteritidis and Escherichia coli. Results showed a predominance of LAB sh…

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)…
