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.
UTILIZZO DEL LATTODINAMOGRAFO PER LA VALUTAZIONE DELL’ATTIVITA’ COAGULANTE DI CAGLI IN PASTA ARTIGIANALI.
2013
The aim of this study was to evaluate the use of Formagraph to determine the milk clotting activity of animal Sicilian rennet pastes. Clotting time (r), curd firming time (k20) and curd firmness (a30) were measured during coagulation tests carried out with pasteurized cows’ milk. The rennet paste samples were collected in 11 dairy factories located throughout western Sicily. The factories produce two different pasta-filata cheese typologies, Caciocavallo Palermitano and PDO Vastedda della valle del Belìce, made with cows raw milk and ewe raw milk, respectively. Commercial liquid calf rennet Naturen and two industrial rennet pastes prepared from kid and lamb abomasums were used for compariso…
Microbial diversity of traditional Sicilian cheeses
2017
Traditional Sicilian cheeses are manufactured in small size farms with raw milk from animals of indigenous breeds and without the addition of starter cultures. In order to transform milk into cheese, the presence of lactic acid bacteria (LAB) is required. The main sources of desirable LAB are generally the milk, the rennet, the equipment used during processing and the dairy environment. In the last years, the microbial characterisation of traditional Sicilian cheeses, such as Caciocavallo Palermitano, Protected Designation of Origin (PDO) Pecorino Siciliano and PDO Vastedda della valle del Belìce have been the object of different studies conducted by our research group. To this purpose, the…
Dominant Lactic Acid Bacteria in Naturally Fermented Milks from Messinese Goat’s Breed
2019
Background: Lactic Acid Bacteria (LAB) are an important group of microorganisms responsible for the fermentation dairy products. This study was done to identify the dominant lactic acid bacteria in naturally fermented milks from Messinese goat’s breed. Methods: Eighteen individual raw milk samples collected from Messinese goat’s breed were acidified at pH 5.20 and left to spontaneously ferment at 37 °C for 4 days. All samples were analyzed for rod- and coccus-shaped LAB. Also, all presumptive LAB were isolated and differentiated according to their phenotypic properties and genetic polymorphisms and then identified by sequencing the 16S rRNA gene. Data were statistically analyzed using SAS 9…
Activation of wooden vats with selected lactic acid bacteria for the year-round production of traditional Vastedda-like cheese
2014
Vastedda is a pasta filata cheese made from raw ewes’ milk without the addition of starter cultures. Cheese production is carried out in wooden vats characterized by microbial biofilms hosting lactic acid bacteria (LAB) responsible for the acidification of the curds. Vastedda cheese was traditionally produced during the summer season, but it is currently produced throughout the year. In order to minimize production variability, several LAB were isolated from Vastedda PDO cheeses, characterized for their technological potential (Gaglio et al., 2014a) and selected to obtain the best strain combination for the production (Gaglio et al., 2014b). In this study, the multiple strain culture compos…
