Osservazioni su alcuni parametri di composizione e igienico-sanitari del latte d’asina

2005

Sono riportati i risultati di un’indagine sulla qualità del latte d’asina prelevato presso quattro aziende siciliane da 27 animali nel corso della lattazione. La ricerca approfondisce alcuni aspetti relativi alla composizione ed all’assetto igienico-sanitario del prodotto, anche in funzione di quanto esplicitato nel Regolamento (CE) 853/2004 che include “altre specie” lattifere e sottolinea la futura emanazione di una normativa più specifica sulla qualità del latte e dei derivati. Gli AA auspicano che la presente indagine, unitamente ad altri studi sull’argomento, fornisca un contributo al fondamento scientifico sul quale dovrebbe essere basata la formulazione di specifici criteri normativi…

Effects of the foal at the milking and dietary supplementation with extra virgin olive oil on jennet milk production

2009

The effects of the foal at the milking and the extra virgin olive oil supplementation in the diet, on the milk obtained by 12 Ragusana jennets were studied. The jennets were each fed 3.5+1.5 kg/d of concentrate+bran, and hay ad libitum. They were divided into 2 equal groups with one group receiving an additional dietary supplement of 100 ml/d of olive oil. Milk was collected at day 20 post foal- ing and every 15-18 d for 5 times. At each collection period jennets were milked 4-times per day. At 07:30 h foals were separated from the jennets and after a 4 hour interval were milked manually (1MNF;1st milking, foal absent). At the end of the 1MNF, each jennet was milked again, with the foals ke…

Effects of Sulla forage (Sulla coronarium L.) on the oxidative status and milk polyphenol content in goats

2015

Abstract Twelve milking Girgentana goats were allocated into 3 groups and fed 3 diets ad libitum in a 3 × 3 Latin square design with 3 periods. The diets were Sulla fresh forage ad libitum (SUL), Sulla fresh forage ad libitum and 800 g/d of barley meal (SULB), and mixed hay ad libitum and 800 g/d of barley meal (HB). Changes were observed in total polyphenol intake, plasma oxidative status, plasma polyphenol content, metabolic status, milk polyphenol content, and total antioxidant capacity. The fresh forage diets (SUL and SULB) increased dry matter, total polyphenol, nontannic polyphenol and tannin intakes, and the milk total protein, casein, milk total polyphenols, and milk free polyphenol…

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…

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…

Effects of grazing Trifolium subterraneum and Lolium multiflorum in various proportions on forage intake and milk production of dairy ewes

2011

The aim of this research was to evaluate the effects of grazing Trifolium subterraneum (T) and Lolium multiflorum (L), as pure or associated crops, on forage intake and milk yield and composition in Comisana ewes. The four following fenced subplots, each of 2500 m2, were used for grazing: T, 100% of surface; L, 100% of surface; TL, T and L on 66.6 and 33.3 % of surface; LT, T and L on 33.3 and 66.6% of surface, respectively. Each subplot was divided into two parcels in order to have two replicates. Forty ewes were divided into eight homogeneous groups, with regard to milk yield, days in milk and live weight. In spring for 70 days, each group grazed daily for 8 h one of the fenced parcels. M…

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…
