Estudio de las resistencias a los antimicrobianos de bacterias zoonóticas y comensales aisladas en alimentos de la provincia de Valencia
2022
Las enfermedades transmitidas por los alimentos constituyen un problema de salud pública creciente en todo el mundo. Dentro de este amplio espectro de enfermedades que pueden ser causadas por la ingesta de alimentos contaminados, las toxiinfecciones alimentarias son aquellas enfermedades que, además de ser transmitidas por los alimentos, son causadas por agentes biológicos o sus toxinas, y suponen uno de los peligros más importantes asociados al consumo de alimentos. Los costes sociales y económicos de estas enfermedades son difíciles de evaluar, ya que implican no sólo costes médicos de tratamiento y hospitalización y jornadas de trabajo perdidas, sino también, en muchos casos, daños irrev…
Production of Functional Crackers Enriched with Olive (Olea europaea L.) Leaf Extract
2016
In recent years, considerable interest has been shown in the functional properties of foods, and a relevant role has been played by phenolic compounds, able to scavenge free radicals. A more sustainable agriculture has to emerge to guarantee food supply over the next years. Wheat, corn, and rice are the most common cereals cultivated, but also other cereal species, such as barley can be appreciated for their peculiarities. Barley (Hordeum vulgare L.) is a C3 winter cereal that shows high resistance at drought and salt stresses. There are growing interests in barley as ingredient for the production of functional foods due to its high content of phenolic compounds and Beta-glucans. In this re…
Biodisponibilidad y efectos biológicos de esteroles en bebidas funcionales
2018
La Sociedad Europea de Aterosclerosis (EAS), basándose en la evidencia de la capacidad de los esteroles vegetales (EV) para disminuir los niveles de c-LDL y a la ausencia de efectos adversos, ha considerado beneficioso el consumo de 2 g EV/día, en personas con hipercolesterolemia y con riesgo cardiovascular moderado y bajo que no precisen tratamiento farmacológico, así como en personas que requieren de tratamiento farmacológico pero no alcanzan los objetivos terapéuticos o tienen intolerancia al mismo. Dado que con la dieta habitual no se alcanza dicha ingesta de EV, en la actualidad, diversos alimentos se enriquecen en EV. Las bebidas a base de zumo de frutas y leche (en las que la UE perm…
Exploiting the Redox Activity of MIL-100(Fe) Carrier Enables Prolonged Carvacrol Antimicrobial Activity
2022
The design of efficient food contact materials that maintain optimal levels of food safety is of paramount relevance to reduce the increasing number of foodborne illnesses. In this work, we develop a smart composite metal-organic framework (MOF)-based material that fosters a unique prolonged antibacterial activity. The composite is obtained by entrapping a natural food preserving molecule, carvacrol, into a mesoporous MIL-100(Fe) material following a direct and biocompatible impregnation method, and obtaining particularly high payloads. By exploiting the intrinsic redox nature of the MIL-100(Fe) material, it is possible to achieve a prolonged activity against Escherichia coli and Listeria i…
Variability of sensory profile and quality characteristics for ‘Pesca di Bivona’ and ‘Pesca di Leonforte’ peach (Prunus persica Batsch) fresh-cut sli…
2015
Abstract Peach genotypes in Southern Italy include the white-flesh ‘Pesca di Bivona’ (‘Murtiddara’, ‘Bianca’, ‘Agostina’ and ‘Settembrina’) and the yellow-flesh ‘Pesca di Leonforte’ (‘Settembrina’, ‘Giallone’ and ‘Ottobrina’ ) landraces, with non-melting clingstone fruit, characterized by a persistent aroma and an excellent flavor that is highly appreciated by consumers. The aim of this work was to assess the suitability of these white- and yellow-flesh landraces to be processed as fresh-cut product with regard to the persistence of their quality and sensory profiles. Fruit of ‘Pesca di Bivona’ and ‘Pesca di Leonforte’ landraces were cut into slices and stored at 5 °C for 3, 5, 7, 12 d. Fre…
Fruit Quality Traits of Two Apricot Cultivars
2010
In this trial we evaluated physical and chemical fruit quality traits and sensory profile of two late-ripening apricot cultivars ‘Vitillo’ and ‘Pellecchiella’. Fruits were harvested at full maturation in three different pickings, at 4 day intervals, to ensure the same fruit quality. To verify quality among different pickings, weight, diameter, soluble solid content, titratable acidity, pH, colour were recorded. To describe and quantify the sensory characteristics of apricot fruits a panel of 10 judges generated 16 descriptors. For each of these attributes judges assigned a score from 1 to 9. Qualitative and sensory data for each attribute were submitted to one way Analysis of Variance (ANOV…
Effect of different salting technologies on the chemical and microbiological characteristics of PDO Pecorino Siciliano cheese
2011
The present work was carried out to evaluate the effect of two salting technologies [dry salting (DS) and the combined dry-brine salting (DBS)] on the chemicophysical and microbiological characteristics of PDO Pecorino Siciliano cheeses of different final weight (6 and 12 kg). Dry matter was significantly influenced by both salting process and final size. Twelve kilogram cheeses treated by DBS showed higher protein content with higher soluble nitrogen per cent than 6 kg cheeses. Salt content was in the range 3.1–4.0% on dry matter. The colour did not show significant differences for any of the factors, but 12 kg cheeses subjected to DS showed higher yellow index than the other cheeses. The …
