Fitting the Stocking Rate with Pastoral Resources to Manage and Preserve Mediterranean Forestlands: A Case Study
2015
Pasture practices have affected Mediterranean forest ecosystems for millennia, and they are still quite widespread in mountainous areas. Nevertheless, in the last decades, the stability of forest ecosystems has been jeopardized due to the abandonment of traditional agro-pastoral practices, so that the gradual reduction of open areas due to progressive succession processes has caused a high increase of grazing pressure by livestock and wild ungulates feeding on forest areas. This paper aims at showing a methodological approach for evaluating the effect of applying measures in order to improve the grazing value of grasslands and ecotonal patches and lower the grazing impact on native woodland…

Compression tests of cv. Nocellara del Belice table olives for texture evaluation during storage
2014
The influence of pasteurization temperature and time of treatment on the flesh firmness and the evolution of microbial communities was studied for table olives Cv. Nocellara del Belice, packed in glass jars and processed with a tunnel pasteurizer. Pasteurization at industrial scale was carried out within a tunnel pasteurizer applying the treatment at 75 °C for 8 min in the thermal center of the jars. Besides flesh firmness and microbial evolutions, pH, total ti-tratable acidity (TTA) and colour were evaluated for the table olives during storage at 6, 12 and 15 months from packing. Table olives showed a high stability and an acceptable flesh firmness for the entire period under observation. …
Study on the tunnel pasteurizer in table olives processing
2014
The application of heat treatment is especially important in maintaining the organoleptic characteristics of fermented agro-food products, which potential consumers perceive as reflecting the quality of these foodstuffs. However, heat treatments can be cause of deterioration of many quality parameters of agro-food products including texture, intended as the consistency of the pulp. Pasteurization is one of the most important steps of the table olives packaging process; it is applied after that olives are properly treated for debittering process. In this study ‘Nocellara del Belice’ table olives produced in 2010 and packaged in glass jars, were subjected to pasteurization at industrial scale…

Persistent Organic Pollutants and Fatty Acid Profile in a Typical Cheese from Extensive Farms: First Assessment of Human Exposure by Dietary Intake
2022
Dairy products represent an important source of beneficial substances for humans. At the same time, they can expose the consumers to environmental contaminants ingested by animals through their diet, influencing their health negatively. This experiment aims to evaluate the risk and benefits related to the consumption of typical stretched cheeses, considering their fatty acid (FA) profile and persistent organic pollutants (POPs) content. Six representative farms, two of them organic, raising Cinisara cattle were selected, considering the typical extensive management systems, based on feeding of natural pasture integrated with concentrate and hay depending on the availability of forage on pas…
Effect of the pasture, in different seasons, and of the ripening time on the Caciocavallo Palermitano cheese
2008
The Caciocavallo Palermitano cheese is made processing Cinisara cow milk, which shows very interesting qualitative characteristics (Bonanno et al., 2004). The aim of this research was to study the effect of the pasture, in different seasons, and of different ripening on the yield in cheese after 24 h and on the chemical composition of the Caciocavallo Palermitano cheese
Effect of the pasture on milk production from Cinisara cows over the seasons
2008
Cinisara is a Sicilian autochthonous breed of dairy cow and its milk is processed to make Caciocavallo cheese. The pasture is the basis of the diet during all the year, but its production is not continuous and homogenous, because of environmental constrains (Alabiso et al., 2005). The feeding integrations are concentrate, hay and or straw, and their quantities given to the animals are different during the year in relation to the pasture resources. The aim of this research was to study the effect of the pasture on milk production from Cinisara cows over the seasons
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…
