Dairy ewes fed with fresh citrus by-product feedstuff: the effect on Vastedda cheese characteristics

2011

Effects of adding solid and molten chocolate on the physicochemical, antioxidant, microbiological, and sensory properties of ewe's milk cheese.

2020

Abstract: A novel dairy product, namely “chocolate cheese”, was produced with two typical Sicilian food products: Pecorino cheese, processed from ewe's milk, and Modica chocolate. The cheese, manufactured with 0%, 5%, 10%, and 15% (w/w) solid or molten chocolate, was evaluated after 0, 2, 4, and 6 weeks of vacuum storage for its nutritional and health properties. The addition of chocolate reduced the pH, protein, fat, and ash; the addition of 5% or 10% molten chocolate reduced hardness (N/mm2). The addition of either solid or molten chocolate resulted in a slight increase (P < 0.1038) in the total polyphenol content, a higher oleic acid content, and less oxidative stability. The microbio…

DETERMINAZIONE DI PARAMETRI CHIMICI MEDIANTE TECNOLOGIA NIR (FOODSCAN™ DAIRY ANALYSER) IN CAMPIONI DI FORMAGGIO “CACIOCAVALLO PALERMITANO"

2012

The aim of the study was to evaluate the “Global Cheese” calibration for FoodScan ™ Dairy Analyser by Foss to determination chemical and nutritional characteristics of “Caciocavallo Palermitano” cheese: fat, protein, chloride, total solids and humidity. A total of 42 samples of “Caciocavallo Palermitano” were analyzed by two methods: FoodScan™ and the official chemical methods. The statistics used for the comparison of the methods showed a more than good capacity of analysis of the NIT method. Therefore FoodScan ™ is a valuable tool to support the activities of analysis of dairy products.

Effet du système d’élevage et de la technologie fromagère sur les caractéristiques sensorielles du fromage Caciocavallo Palermitano.

Effect of farming system and cheesemaking technology on the physicochemical characteristics, fatty acid profile, and sensory properties of Caciocaval…

2012

Abstract Caciocavallo Palermitano is a typical stretched-curd cheese that has been produced over the centuries in Sicily according to traditional cheesemaking technology and using raw milk from autochthonous cow breeds reared at pasture. The objective of this experiment was to evaluate the effects of the farming system and processing technology on the characteristics of Caciocavallo Palermitano cheese, with particular regard to the fatty acid profile. The farming system was either extensive, using autochthonous cows fed a pasture-based diet, or intensive, with specialized dairy cow breeds fed mainly hay and concentrate. The cheese-processing technology was either artisanal, using traditiona…

Preliminary Evaluation of the Influence of Traditional Dairy Plant Equipment on the Microbiological Quality of “Caciocavallo Palermitano” Cheese

2010

Caciocavallo Palermitano” is a raw cows’ milk cheese produced within Palermo province (Sicily), processed according to “pasta-filata” cheese technology without starter addition. Production flow-sheet includes a 15-minute milk bulk resting in “tina”, the traditional wooden vat used for cheese-making. This study was aimed to evaluate the influence of traditional equipment on the characteristics of cheese; at this stage, it was forwarded to the characterization of the microbiological populations of “Caciocavallo Palermitano” during each step of manufacturing. Two milk bulks (A and B), from different farming systems, were compared before and after resting in tina. After delivery at dairy factor…

Transfer, composition and technological characterization of the lactic acid bacterial populations of the wooden vats used to produce traditional stre…

2015

The biofilms of 12 wooden vats used for the production of the traditional stretched cheeses Caciocavallo Palermitano and PDO Vastedda della valle del Belìce were investigated. Salmonella spp. and Listeria monocytogenes were never detected. Total coliforms were at low numbers with Escherichia coli found only in three vats. Coagulase-positive staphylococci (CPS) were below the enumeration limit, whereas lactic acid bacteria (LAB) dominated the surfaces of all vats. In general, the dominance was showed by coccus LAB. Enterococci were estimated at high numbers, but usually between 1 and 2 Log cycles lower than other LAB. LAB populations were investigated at species and strain level and for thei…

Persistent Organic Pollutants and Fatty Acid Profile in a Typical Cheese from Extensive Farms: First Assessment of Human Exposure by Dietary Intake

2022

Dairy products represent an important source of beneficial substances for humans. At the same time, they can expose the consumers to environmental contaminants ingested by animals through their diet, influencing their health negatively. This experiment aims to evaluate the risk and benefits related to the consumption of typical stretched cheeses, considering their fatty acid (FA) profile and persistent organic pollutants (POPs) content. Six representative farms, two of them organic, raising Cinisara cattle were selected, considering the typical extensive management systems, based on feeding of natural pasture integrated with concentrate and hay depending on the availability of forage on pas…

Analysis of microbiological variation in PDO Vastedda della valle del Belìce cheese during the storage period

2011

The PDO “Vastedda della valle del Belìce” is a Sicilian pasta filata sheep cheese, made from raw milk without starter addition. It is a small round cheese without rind, weighing about 500-700 g. It is cheese is marketed also out of Sicily to allow its marketing and to prolong its shelf-life. The aim of this work was to evaluate the variation of microbiological parameters during the shelf-life period. Then 162 Vastedda cheeses from 18 cheese-making processes in 7 farms have been analysed at different times of storage at 4°C (0, 15, 30, 45, 60, 75, 90, 105, 120 days). Coliforms and E. coli were detected into 7/18 cheese-making processes and their count decreased during the storage period. Ent…
