Green and Quick Extraction of Stable Biophenol-Rich Red Extracts from Grape Processing Waste

2021

The extraction of grape processing waste (wine pomace) via microwave-hydrodiffusion and gravity (MHG) from three different cultivars grown in Sicily (Syrah, Perricone and Nero d’Avola) rapidly affords aqueous extracts highly concentrated in valued biophenols including flavonoids, anthocyanins and phenolic acids. The method does not employ organic solvent, acid or base and does not require grinding or freeze drying of the wine pomace nor separation of the grape skins from seeds and stem. All the extracts have a pronounced stability as shown by their red-violet color fully retained after storage for more than a year (15 months) in freezer under air. Concentrations of phenolics up to…

DETERMINATION OF MACRO ELEMENTS IN GLUTEN-FREE FOOD FOR CELIAC PEOPLE BY ICP-OES

2015

This paper is the first analytical approach to the study of seven nutrients in the gluten-free foods for celiac people. The ICP-OES technique was used. One of the advantages about the use of ICP-OES for this characterization is the high selectivity and low interferences for studied elements. The concentration values of K, Li, Sr, Na, Ca, Mg and Al in seventeen gluten-free food samples are reported. Considering the average concentrations of the elements analyzed, excluding lithium, in the present study it can be concluded that they are inadequate if compared with the recommended daily intake by international organisms, providing only from 1.5 to 20% of the RDI for the essential metals. In pa…

Effects of gamma-irradiation on the alpha-tocopherol and fatty acids content of raw unpeeled almond kernels (Prunus dulcis)

2014

Abstract The present study evaluated fatty acid composition and α-tocopherol content of almond as a function of irradiation dose in order to determine dose levels causing minimal undesirable changes to almonds. Raw unpeeled almonds variety Tuono ( Prunus dulcis (Mill.) D. A. Webb) were irradiated using 60 Co source at dose of 0.5, 1.5, 3, 6, 8 and 10 kGy. Both control and irradiated samples were kept frozen and immediately analyzed. The data obtained showed no change in fatty acid compositions up to a dose of 10 kGy; on the contrary, a general trend observed is that increasing the dose of irradiation resulted in the decrease of α-tocopherol content. The study has shown that irradiation is a…

Fornir los castells e vila de Murvedre. Las obras y el aprovisionamiento del castillo de Morvedre durante la guerra de Castilla (1365-1366)

2021

Los castillos eran la espina dorsal del sistema defensivo del reino de Valencia, así como de todos los estados feudales. A través del análisis de la contabilidad de un libro de obras relativo al castillo de Sagunt analizamos el papel de los castillos valencianos en la defensa del territorio y su importancia en la creación de tejido económico y en la movilización de mano de obra. El volumen es especialmente interesante porque también refleja el abastecimiento alimentario y la compra de armamento. Además, las cuentas analizadas se realizaron durante la Guerra de Castilla (1356-1375) uno de los momentos claves de la historia de la Corona de Aragón.

Determinantes del uso del semáforo alimenticio en el marco del Health Belief Model

2019

Según datos de la Organización Mundial de la Salud (OMS), desde 1975 la obesidad y el sobrepeso se han triplicado en el mundo. Esta situación, tiene relación con la mala alimentación de la población mundial, ocasiona numerosas enfermedades. Por ello, tanto las organizaciones sin fines de lucro, como los gobiernos, y las empresas están adoptando medidas para frenar estos hábitos nocivos y mejorar la calidad de la alimentación de los ciudadanos (Levy, Fein y Schucker, 1996; Balcombe, Fraser y Di Falco, 2010; Hawley et al., 2013).la OMS sugiere ciertas pautas a nivel personal y de la industria alimentaria. A nivel personal los consumidores también están cada vez más concienciados de la importa…

Control of Growth and Persistence of Listeria monocytogenes and β-Lactam-Resistant Escherichia coli by Thymol in Food Processing Settings

2020

The main objective of this study was to evaluate the efficacy of thymol in controlling environmental contamination in food processing facilities. The effect of thymol was tested as an agent to prevent planktonic and bacterial biofilm growth of twenty-five Listeria monocytogenes isolates from a variety of foods and five Escherichia coli isolates from a farm. The E. coli isolates were positive for extended spectrum &beta

Application of bacteriocins in vegetable food biopreservation.

2007

Bacteriocins are generally recognized as "natural" compounds able to influence the safety and quality of foods. In the past years, a lot of works have been aimed to the detection, purification and characterisation of bacteriocins, as well as to their use in food preservation strategies. A list of review articles dealing with the application of bacteriocins to the protection of foods of animal origin is also available in literature, but it lacks for a summary on the utilization of bacteriocins in vegetable foods. These biopreservatives can be used in a number of ways in food systems and this paper mainly focuses on the state-of-the-art application of bacteriocins from lactic acid bacteria (L…
