Microbial characterisation of fermented meat productions from the Sicilian breed "Suino Nero dei Nebrodi"
2012
Two traditional sausage products (“salsiccia” and “salame”) processed from the raw meat of the Black Sicilian swine “Suino Nero dei Nebrodi” were microbiologically investigated during the manufacturing and ripening stages. Both products were dominated by lactic acid bacteria (LAB), especially rod-shaped types. The concentration of enterococci was consistent in salame. Coagulase-negative cocci increased slower than LAB. Yeasts showed an increasing trend during the ripening of both products. Enterobacteriaceae were counted at a constant level of about 105 CFU/g in both products, while pseudomonads diminished during ripening. Coagulase-positive staphylococci, Listeria monocytogenes and Salmone…
New trends in technology and identity of traditional dairy and fermented meat production processes
2014
Interest in ecofood tourism is strictly related to the consumption of products associated with the geographical area visited. Local products are often requested by consumers living far from the production zones (e.g. in bistro restaurants that reproduce the atmosphere of typicality). This phenomenon, if on the one hand guaranteeing the continued popularity of certain traditional foods, highlights the inherent dangers that certain types of food pose. They could spread the risks to a much wider area that they might typically inhabit. The higher the demand for certain products, the more variations of the production processes of the traditional products there will be. This is particularly evide…
Caramel odor: Contribution of volatile compounds according to their odor qualities to caramel typicality
2014
Abstract Odor of food constitutes one of the main drivers of the consumers' acceptance. Its characterization thus represents a main challenge for the food industry. Gas chromatography/olfactometry (GC/O) constitutes an intersection between physico-chemical and sensory studies by using the human nose as a detector to evaluate the odor properties of volatile compounds. As GC/O does not make possible the evaluation of mixture of odorants, we propose an original approach to evaluate the impact of compounds on the typicality of caramel aroma by considering their odor qualities in mixtures. Indeed, the present study relies on the main hypothesis that the qualitative properties are as important as…
A large factory-scale application of selected autochthonous lactic acid bacteria for PDO Pecorino Siciliano cheese production
2016
The main hypothesis of this study was that the autochthonous lactic acid bacteria (LAB) selected for their dairy traits are able to stabilize the production of PDO (Protected Denomination of Origin) Pecorino Siciliano cheese, preserving its typicality. The experimental plan included the application of a multi-strain lactic acid bacteria (LAB) culture, composed of starter (Lactococcus lactis subsp. lactis CAG4 and CAG37) and non starter (Enterococcus faecalis PSL71, Lactococcus garviae PSL67 and Streptococcus macedonicus PSL72) strains, during the traditional production of cheese at large scale level in six factories located in different areas of Sicily. The cheese making processes were foll…

SMART CULTURAL HERITAGE AND SUSTAINABLE URBAN DESIGN EXPERIMENTAL DISTRICTS IN SICILY AND IN GREECE
2014
The design is a creative process for the production of objects , projects and services that are used to meet any need. In architecture and city planning in the design process is designed especially to meet the needs of living. Sustainable urban design is in fact a creative process for the implementation of sustainable practices. Adding up the benefits for all sectors that deal with sustainability indices , it can be argued that the reduction of the environmental impact , better use of the cultural and environmental resources and an improved quality of life for the inhabitants are the main advantages to build sustainable urban development. There are various urban problems in certain cities o…
Perception of quality and complexity in wine and their links to varietal typicality: An investigation involving Pinot noir wine and professional tast…
2020
International audience; Quality and complexity are abstract terms employed frequently to describe a wine's overall attributes. In the present study, we investigated: (i) attributes driving wine professionals' judgments of quality and complexity in Pinot noir wines; (ii) the relation between these two abstract concepts; and (iii) association of each concept with varietal typicality. Twenty-two wine professionals evaluated 18 New Zealand Pinot noir wines in both clear and opaque glassware via two sensory tasks, a descriptive rating task and an 8-attribute, perceived complexity questionnaire. Sensory data were associated with wine UV-spectrophotometry colour measures to aid interpretation of t…
Nella giostra della social photography
2018
Oggi la fotografia va ben oltre la fissazione dei ricordi. Il volume riprende la nota ricerca di Bourdieu relativa agli usi sociali della fotografia intorno alla metà degli anni Sessanta. Da questa si desume che un tempo gli scatti dei non professionisti, mediati dall'habitus di classe, intercettavano i momenti topici della vita sociale e le tipicità espresse da una cultura condivisa. Mentre le foto dei professionisti aspiravano a riconoscere i momenti decisivi in senso autoriale in vari ambiti (reportage, moda, paesaggio, pubblicità ). Oggi, in virtù dell'accelerazione sociale, siamo incerti sulla direzione della Storia. Tutti i fenomeni sono potenzialità del mondo, come tutte le immagini …
Just noticeable differences in component concentrations modify the odor quality of a blending mixture.
2008
International audience; The odors we perceive are mainly the result of mixtures of odorants that, however, are commonly perceived as single undivided entities; nevertheless, the processes involved remain poorly explored. It has been recently reported that perceptual blending based on configural olfactory processing can cause odorant mixtures to give rise to an emergent odor not present in the components. The present study examined whether specific component proportions are required to elicit an emergent odor. Starting from the composition of a ternary target mixture in which an emergent pineapple odor was perceived, 4 concentration levels of each component were chosen to elicit just noticea…
