PROCEDIMENTO PER LA PURIFICAZIONE DI MANNA IMPURA ED OTTENIMENTO DI MANNA ARRICCHITA E SUO IMPIEGO
2015
The invention consists in an original procedure to purify dirty manna, an under-utilized waste matter from the lymph poured from fraxinus plants, to obtain a product comparable with the pure edible “manna”, and enriched in bioactive components with respect to pure manna. Methods to treat the so obtained purified manna are also part of the invention.
Aseasonal sheep and goat milk production in the Mediterranean area: Physiological and technical insights
2015
Abstract Aseasonal or out-of-season milk production for small ruminants raised in Mediterranean areas refers generally to milk having to be produced at a time that corresponds to summer which is when conditions are generally unfavourable with respect to both physiological aspects and nutritional factors related to seasonal climatic trends. In fact, sheep and goat milk production in the Mediterranean basin is mostly based on pasture utilization and thus follows the pasture availability pattern. This causes a strong seasonal pattern to the amount of milk processed by cheese processes plants, with the peak being in the spring, a marked reduction in early summer and nil or low availability of m…
Feeding and management techniques to favour summer sheep milk and cheese production in the Mediterranean environment
2015
Sheep milk production in summer can lead to a diversification of milk products and to a more regular product distribution in the market throughout the year. However, in Mediterranean countries small ruminant production cycles are subjected to seasonal variations in forage resources. During summer, a key period for out of season production systems, nutrition plays a fundamental role in regulating the quantity and quality of milk production. In this review, feeding strategies and techniques that could be applied for out of season production in dairy ewes under different Mediterranean conditions are described for intensive, pasture-based and mixed systems. The most common feeding strategies us…
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…
Effect of refrigerated storage on microbiological, chemical and sensory characteristics of a ewes’ raw milk stretched cheese
2017
This study aimed to describe the effects of refrigerated storage up to 180 days on microbiological, chemical, physical, and sensory characteristics of a PDO ewes’ raw milk stretched cheese. To this aim, a total of 224 cheeses were manufactured in four consecutive production weeks, and series of 32 of them were examined before packaging and after 15, 30, 60, 90, 120, and 180 d of storage at 4 ± 2 °C in the dark, respectively. Lactic acid bacteria cocci displayed the highest levels (7.8 Log CFU*g−1) during early storage and decreased progressively over time (7.4 Log CFU*g−1), while the opposite trend was observed for lactic acid bacteria rods (from 6.5 to 7.3 Log CFU*g−1). TMC and enterocci s…
Lipid composition and metabolism of European sea bass (Dicentrarchus labrax L.) fed diets containing wheat gluten and legumes meals as substitutes fo…
2013
The role of dietary protein source on growth performance and lipid metabolism in European sea bass (Dicentrarchus labrax) was investigated, by the evaluation of fat content in different tissues, plasma metabolites, liver lipogenic activity and fatty acid composition of dorsal muscle tissue.Five isonitrogenous (490gkg-1crude protein dry-matter basis) and isolipidic (170gkg-1lipid dry-matter basis) diets with graded levels of wheat gluten, soybean and pea meal in substitution of fish meal were evaluated in European sea bass (initial body weight 23.9±0.1) for 96days. There was a significant difference (p<0.05) in dorsal muscle and liver lipid contents. Plasma glucose and cholesterol levels …
La nutrizione proteico/aminoacidica gold standard nel trattamento dell’obesità e del sovrappeso in soggetti con alterazioni endocrino-metaboliche

Gli Autori hanno voluto testare l’efficaci…
La salute dei migranti
2016
Da un’analisi della letteratura sulle condizioni sociali e sanitarie dell’immigrato, si possono determinare alcune aree critiche che necessitano di particolare attenzione soprattutto in termini di programmazione e di pianificazione di politica e di comunicazione socio-sanitaria. Possiamo suddividere queste aree in tre ambiti sommariamente delimitati da alcune condizioni patologiche, fisiologiche e sociali. - condizioni patologiche: malattie infettive (tb, mst, ...), malattie dermatologiche, disagio/malattie psichiatriche, traumi e incidenti, NCD; - condizioni fisiologiche: maternità, infanzia, vecchiaia; - condizioni sociali: prostituzione e tratta, abuso, detenzione; - aggravanti: disagio …
