Alkaline phosphatase survey in pecorino siciliano PDO cheese
2021
The determination of alkaline phosphatase (ALP) in cheeses has become an official method for controlling cheeses with a protected designation of origin (PDO), all of which use raw milk. PDO cheeses, characterized by high craftsmanship, usually have an uneven quality. However, for these cheeses, it is necessary to establish ALP values so that they can be defined as a raw milk product. In this study, a dataset with Pecorino Siciliano PDO samples was analyzed to determine ALP both at the core and under the rind. The results showed that there was no significant difference between the different zones in Pecorino cheese. A second dataset of 100 pecorino cheese samples determined that ALP was only…
Impiego di batteri lattici autoctoni per il miglioramento igienico-sanitario del Pecorino Siciliano DOP
2017
Il Pecorino Siciliano DOP è considerato il più antico formaggio prodotto in Sicilia e, probabilmente, d’Europa. Le citazioni storiche sulla sua antica origine risalgono al IX secolo a.C. in uno dei passi più famosi dell’odissea di Omero, quando Ulisse incontra Polifemo. In seguito, anche Aristotele e Plinio esaltano il gusto unico di questo formaggio. In particolare, proprio Plinio, nella sua opera “Naturalis Historia”, redige una carta dei formaggi nella quale vengono citati, tra i migliori pecorini,quelli provenienti da Agrigento. Fra le caratteristiche peculiari del Pecorino Siciliano DOP vanno annoverati il sapore leggermente piccante e l’incantevole profumo di pascolo. Il Pecorino Sici…
Selected lactic acid bacteria as a hurdle to the microbial spoilage of cheese: Application on a traditional raw ewes' milk cheese
2013
To evaluate the efficacy of lactic acid bacteria (LAB) to improve the hygienic safety of a traditional raw milk cheese, the raw ewes’ milk protected denomination of origin (PDO) Pecorino Siciliano cheese was used as a model system. Different Pecorino Siciliano curds and cheeses were used as sources of autochthonous LAB subsequently used as starter and non-starter LAB. These were screened for their acidification capacity and autolysis. Starter LAB showing the best performance were genotypically differentiated and identified: two strains of Lactococcus lactis subsp. lactis were selected. From the nonstarter LAB, Enterococcus faecalis, Lactococcus garvieae and Streptococcus macedonicus strains…
EFFECT OF ADDING SOLID AND MOLTEN CHOCOLATE ON THE POLYPHENOL CONTENT, CHEMICAL, TEXTURAL, MICROBIOLOGICAL AND SENSORY ASPECTS OF PECORINO SICILIANO …
In this project we used two specific food products, which are typically Sicilian, Pecorino Siciliano cheese and Modica chocolate, that have unique texture and taste. “Chocolate cheese” is produced with the aim of increasing the consumption of cheese especially among children, targeting the purpose of improving public health. In this research we investigated chocolate cheese including solid and molten chocolate in three levels of 5%, 10% and 15% at four ripening times (T0 = fresh, T1 = 2 weeks, T2 = 4 weeks and T3 = 6 weeks). The results showed that the addition of chocolate significantly (p ≤ 0.05) decreased the pH, ash and protein content of the Pecorino Siciliano cheese, whereas it had no…

Il formaggio al cioccolato ottenuto combinando due alimenti tradizionali, il pecorino ed il cioccolato di Modica IGP, può rappresentare un prodotto lattiero caseario innovativo e funzionale
Transfer of milk fatty acids to Pecorino Siciliano cheese
2011
In previous studies it was observed that milk fatty acid (FA) composition is mainly affected by diet, and when ruminants graze pasture the percentages of polyunsaturated FA and conjugated linolenic acid (CLA) are higher than in milk from preserved forage. The maintenance in the cheese of the beneficial FA profile of milk from grazing ruminants is advisable. Little number of study exists concerning the effect of milk processing conditions on cheese FA profile, but no study was done with regard to Pecorino Siciliano cheese. The aim of this study was to evaluate the transfer of FA from ewes milk to cheese manufactured according to the Pecorino Siciliano technology, in order to verify if the ch…
Genotypic characterization of lactic acid bacteria isolated from traditional Pecorino Siciliano cheese
2008
A total of 468 lactic acid bacteria (LAB) isolates from the interior of six traditional Pecorino Siciliano cheeses during ripening (1, 30 and 90 days) were characterized genotypically in order to assess the biodiversity within this wild microbial population. Two DNA-based technique, PCR and PFGE were used for genetic typing of isolates. Of the 468 isolates, species-specific PCR analysis showed that 79, 58, 2, 9 and 4 isolates reacted with primers for Lactobacillus paracasei, Lb. plantarum, Lb. pentosus, Lb. rhamnosus and Lb. curvatus, respectively and no isolates reacted with the Lb. casei primers. Genus-specific PCR analysis showed that 59 isolates reacted positively with the lactococcal p…
Microbiological quality of Pecorino Siciliano "primosale" cheese on retail sale in the street markets of Palermo, Italy
2011
Pecorino Siciliano (PS) “primosale” is a traditional Sicilian fresh soft cheese made from sheep’s milk. Short-ripening time and production from unpasteurized or raw milk can facilitate bacterial contamination of PS “primosale”. The microbiological quality of “primosale” on retail sale in the street markets of Palermo, Italy was studied by detecting the common food pathogens Listeria monocytogenes and Staphylococcus aureus and indicator microorganisms, such as Escherichia coli, Enterobacteriaceae and Staphylococcaceae. In our study, 4% and 44% of the samples, respectively, did not comply with the acceptability levels fixed by European regulations for S. aureus and E. coli. A high contaminati…
