A multivariate statistical and relaxometry approach to study the provenance and traceability of dairy products
Myosin heavy chain isoforms, fatty acid composition, sensory evaluation and quality of cinta senese pig meat
2018
The aims of this study were to examine the effects of myosin heavy chain (MHC) isoforms on Cinta Senese meat and sensory quality. The research was carried out on 65 pigs and muscle samples characteristics such as MHC isoform, meat quality, fatty acid composition, and sensory were evaluated. The results demonstrated that MHC slow isoform content was significantly correlated with pH24h (r=0.25, P<0.05) and drip loss (r=-0.31, P<0.005), whereas the content of MHC isoforms was only weakly correlated with fatty acids. Sensory evaluation was done by a trained panel test and the results shown that the MHC fast/slow ratio was correlated with the juiciness (r=-0.32, P<0.005), off-flavor (r=0.33, P<0…
Desarrollo y caracterización de nuevos nanobiocomposites con propiedades mejoradas mediante varios métodos de procesado de interés en envasado de ali…
2015
El presente trabajo tiene como objetivo mejorar las propiedades de matrices biopoliméricas para su uso en aplicaciones de envasado de alimentos mediante el desarrollo de nanobiocompuestos utilizando diferentes metodologías de procesado o estrategias de incorporación de materiales nanoestructurados en el interior de las matrices biopoliméricas. Dos estrategias de incorporación fueron empleadas. La primera de ellas estaba basada en una pre-incorporación de los aditivos nanoestructurados, también llamados nanoaditivos, en oligómeros de ácido láctico mediante tecnologías de polimerización in situ (específicamente policondensación), dando lugar a masterbatches que, posteriormente, se mezclaban c…

Le nuove reti di innovazione dello sviluppo sostenibile: i network agro-alimentari biologici in Sicilia
2012
The alternative food network, especially GAS (Solidarity Purchase Groups), are considered like laboratories where testing new models of innovation system (new social paradigms). In this paper is focused the theory of transitions management. With the help of Social Network Analysis, we tried to understand the network between GAS and associations both of them involved in the processes of food production and consumption, aimed at promoting sustainable development in Sicily.
Effect of the mechanical harvest of drupes on the quality characteristics of green fermented table olives
2015
Background: Because of damage caused by mechanical harvesting, the drupes for table olive production are traditionally hand harvested. Until now, no data have been available on the microbiological and chemical features of mechanically harvested drupes during fermentation. Results: Drupes mechanically harvested and inoculated with Lactobacillus pentosus OM13 were characterized by the lowest concentrations of potential spoilage microorganisms. On the other hand, drupes mechanically harvested and subjected to spontaneous fermentation showed the highest concentration of Enterobacteriaceae and pseudomonads during transformation. The lowest decrease of pH (4.20) was registered for the trials inoc…
“Five Keys to Safer Food” and COVID-19
2021
On 11 March 2020, coronavirus disease 2019 (COVID-19) was declared a pandemic by the World Health Organization (WHO) and, up to 18:37 a.m. on 9 December 2021, it has produced 268,440,530 cases and 5,299,511 deaths. This disease, in some patients, included pneumonia and shortness of breath, being transmitted through droplets and aerosols. To date, there is no scientific literature to justify transmission directly from foods. In this review, we applied the precautionary principle for the home and the food industry using the known “Five Keys to Safer Food” manual developed by the World Health Organization (WHO) and extended punctually in its core information from five keys, in the light of new…

Microbiological and safety evaluation of green table olives marketed in Italy
2011
The microbiological and safety conditions of green table olives sold on the Italian market were evaluated on 40 samples, 20 loose and 20 packed in containers, purchased at street markets and supermarkets. The olives were analyzed for microflora and food safety indices, and for aflatoxin B1 and ochratoxin A occurrence, and the results showed acceptable security. There was wide heterogeneity in the microflora, the numerical values being in relation to the olive type. The microbial population was dominated by the yeasts and lactic bacteria responsible for the fermentation process, and their numbers, together with the metabolic activity, led to conditions unfavorable for the development of path…
