Development of an ad hoc natural whey starter culture for the production of Vastedda della valle del Belìce cheese
2013
This work was aimed to characterize the autochthonous lactic acid bacteria (LAB) of PDO Vastedda della valle del Belìce cheeses, produced in several dairy factories, for the development of an ad hoc starter culture preparation for the production of this cheese. To this purpose, winter and spring productions were analysed, in order to isolate LAB adapted to perform the fermentation at low temperatures. Plate counts showed the total microbial counts (TMC) till levels of 9 -1almost 10 CFU g and all cheese samples were dominated by coccus LAB. Not all samples were positive for the presence of enterobacteria, but when they were found their concentrations were at similar levels in both seasons. A…
Effect of substitution of barley and tickbean to maize and extruded soybean in the diet on milk and cheese from ewes grazing under two different stoc…
2007
This experiment aimed to verify the effects of a concentrate supplement based on barley and tickbean (BT), compared with a concentrate of maize and extruded soybean meal (MS), on milk and cheese yield and composition of ewes grazing with different stocking rate (SR). Thirty two Comisana ewes, divided into four groups, for 50 days in spring were allowed to graze plots of a mixed sward of Italian reygrass and berseem clover with a low (LSR, 23 ewes/ha) or a high SR (HSR, 38 ewes/ha) and fed BT or MS. Herbage allowance per ewe was more than double at LSR compared to HSR (P<0.001), and daily milk yield was 10 to 15% higher (P<0.01) in the LSR-BT ewes than in the other groups. Milk composition, …
L’affresco con la Virgo lactans “in maestà” e la Trinità tricefala: un’opera castigliana?
2023
Nel saggio si approfondisce la lettura iconografica di un affresco tardo-gotico dell'ultimo quarto del XV secolo conservato nella chiesa di Santa Maria la Porta di Geraci Siculo (PA). La Madonna che allatta il Bambino, il tipo di trono architettonico in cui è posta e la presenza della rara iconografia della Trinità tricefala suggeriscono una matrice iberica, probabilmente castigliana The essay explores the iconographic interpretation of a late Gothic fresco from the last quarter of the 15th century preserved in the church of Santa Maria la Porta in Geraci Siculo (PA). The Madonna suckling the Child, the type of architectural throne on which she is placed and the presence of the rare iconogr…
Czy mleko modyfikowane może wydłużyć czas karmienia piersią?
2022
Karmienie naturalne jest najlepszym sposobem żywienia niemowlęcia. Położne i lekarze pediatrzy powinni dążyć do promocji karmienia naturalnego w celu wydłużania okresu karmienia piersią. W artykule autorstwa lekarza specjalisty pediatrii i gastroenterologii dziecięcej przedstawiono najważniejsze problemy związane z żywieniem niemowląt oraz choroby mogące spowodować przedwczesne zakończenie karmienia naturalnego. Podjęto próbę zdefiniowania praktycznych sytuacji klinicznych, w których czasowe zastosowanie mieszanki modyfikowanej może paradoksalnie pomóc, a nie przeszkodzić w utrzymaniu karmienia naturalnego.
Ecology of Vastedda della valle del Belìce cheeses: A review and recent findings to stabilize the traditional production
2018
The increasing request for classic foods has led to a higher demand for cheeses enjoying a “recognition of quality” status. This phenomenon has also affected Sicilian dairy products, in particular protected designation of origin (PDO) “Vastedda della valle del Belìce” (VdB), a cheese traditionally available only during the summer season, but requested year round. The variations of the microbial populations of raw milk among the seasons influence the microbiological quality of the cheeses produced. This review article reports the historical importance of cheeses and the traditional equipment used for dairy productions in Sicily with a specific focus on VdB. The microbial ecology of this chee…
Genetic variability at αs2-casein gene in Girgentana dairy goat breed
2014
Casein genes are highly polymorphic and the high degree of variability has qualitative and quantitative effects on milk composition thereby affecting chemical, physical and technological properties of goat milk. The aim of this work was to evaluate the genetic polymorphisms of the αs2-casein (CSN1S2) gene in the endangered Girgentana dairy goat breed in order to assess the genotypes distribution, as it is known genotype influences technological and nutritional milk properties. The study was performed on 207 sample of Girgentana goat breed, analysed with different PCR protocols. The most frequent alleles was A (0.722), followed by F (0.225), C (0.051) and E (0.002) while B, D and 0 alleles w…
