Candida zemplinina for Production of Wines with Less Alcohol and More Glycerol
2016
We developed a new protocol for winery mixed fermentations, using the selected Candida zemplinina yeast strain Cz3. The results of a two-year study, in which red musts (Merlot in 2010; Merlot, Nero d’Avola and Frappato in 2011) were inoculated with Cz3, is discussed. These wines were compared with wines obtained by inoculation with commercial Saccharomyces cerevisiae yeast strains (NDA21 and AR06 in 2010; NDA21 in 2011), or with those obtained by spontaneous fermentation (only in 2011). The inoculation of Cz3 always resulted in a two-phase fermentation: the first phase was driven by the C. zemplinina strain, while the second was dominated by the indigenous S. cerevisiae yeasts coming from t…
A method to discriminate between the Candida stellata and Saccharomyces cerevisiae in mixed fermentation on WLD and lysine agar media
2016
This paper presents a simple method to distinguish between Candida stellata and Saccharomyces cerevisiae yeasts during microbiological analyses. The method is based on differential yeast growth on a medium containing cycloheximide and a medium containing lysine as only nitrogen source (lysine agar). The cycloheximide resistance of 45 yeast strains belonging to Candida stellata, Hanseniaspora uvarum, Hanseniaspora guilliermondii, Metschnikowia pulcherrima, Torulaspora delbrueckii, Zygosaccharomyces bailii, Kluyveromyces thermotolerans and Zygoascus hellenicus, and 14 strains of Saccharomyces cerevisiae and Saccharomyces bayanus on WL nutrient agar, was assayed. Cycloheximide resistance is ch…
The Wine: typicality or mere diversity? The effect of spontaneous fermentations and biotic factors on the characteristics of wine
2016
Abstract Wine is probably one of the main fermented beverages for which the recognition of the “territoriality” is fundamental for its appreciation. The sensory profile of wine is significantly affected by microbial activities, and indigenous microorganisms may significantly contribute to the expression of wine typicality. The microbial ecology of wines is complex and includes several species and strains of yeasts, bacteria and molds. Several works showed the positive effects of spontaneous fermentations on the quality of wine as a consequence of the growth of different species and/or strains together at high levels. Furthermore, a new style of “natural” winemaking is gaining importance, si…
Mineral essential elements for nutrition in different chocolate products
2016
In this work, the essential mineral nutritional elements in cocoa beans, in chocolates at different cocoa percentage (60,70,80 and 90%) and in milk chocolate are evaluated. Dark chocolates are confirmed as an excellent source of magnesium (252.2 mg/100 g) and iron (10.9 mg/100 g): in chocolate containing 90% cocoa, their content corresponds to, respectively, 67.0% and 80.3 of Nutrient Reference Values (NRV) in the European Union. The chocolate containing 90% cocoa is also a good source of zinc (3.5 mg/100 g), which is important for the immune system, and selenium (0.1 mg/100 g). Three main components suitable to explain the mineral concentrations are analyzed by factor analysis. The compone…
Biochemical and nutritional traits of sea bass (Dicentrachus labrax) from different rearing systems
2009
Farmed European sea bass (Dicentrarchus labrax), sampled from three different culture systems (intensive in sea-cages, intensive in land-based basins and extensive in lagoon and storage basins of salt-work), of the Northern, Central and Southern Italy, were analyzed with the aim to employ nutritional trait to describe and to distinguish the “origin” of the product. Lipid and fatty acid profile, strongly affected by the feeding history and environmental factors, responsible of the nu- tritional and perceived quality of fish product, are proposed as marker of origin.
A Tool to Assess Architectural Education from the Sustainable Development Perspective and the Students' Viewpoint
2021
[EN] Architectural education plays a fundamental role in achieving sustainable development by training future professionals who can contribute to sustainability through their practice. Nevertheless, to ensure the introduction of sustainable development in the education of future architects, it is fundamental to understand what is being done and what could be improved. Despite this, a big gap has been detected in the assessment of architectural education in Spain and worldwide. Thus, a close-ended questionnaire for students has been designed based on the outcomes from a literature review, exploratory interviews with specialists, and the qualitative analysis of two schools of architecture. Ad…
Menstrual problems and lifestyle among Spanish university women
2020
Menstrual problems affect many young women worldwide, conditioning both their academic performance and quality of life. This study sought to analyse the prevalence of menstrual problems and their possible relationship with lifestyle among Spanish university women, as part of a research project (UniHcos Project) involving a cohort of 11 Spanish universities with 7208 university students. A descriptive analysis was performed using the bivariate chi-square test and the Student&rsquo
Validation of eating habits subscale in children (sehan: spanish version) from 10 to 12 years.
2015
Introducción: Es necesario identificar hábitos alimentarios de riesgo para frenar el aumento de la prevalencia del sobrepeso infantil y garantizar el derecho a la salud del niño. Para ello, se requiere el uso de instrumentos validados en contextos escolares y familiares. Objetivo: Validar una Subescala de Hábitos Alimentarios en Niños (SEHAN), para su uso en escolares españoles entre 10 y 12 años. Método: Las propiedades psicométricas de la SEHAN se estudiaron en 3 apartados: Validez y lógica del instrumento, fiabilidad y consistencia interna, y validez criterial. En el primer apartado participó un grupo de 5 expertos, que valoró la suficiencia, claridad, coherencia y relevancia del instrum…
ETIOBE: Un protocolo de intervención para la obesidad infantil apoyado en las tecnologías de la información y la comunicación
2015
El sobrepeso y la obesidad infantil, constituyen hoy en día un grave problema de salud en todo el mundo. La elevada prevalencia de la obesidad infantil ha llevado a que países como Estados Unidos y Europa inviertan en recursos físicos y económicos para desarrollar estrategias capaces de paliar y frenar este alarmante incremento. Sin embargo, a pesar de todo este esfuerzo, la realidad muestra cómo cada vez son más las personas afectadas de este problema. Este problema adquiere una gran magnitud debido a las consecuencias físicas, psicológicas y sociales asociadas al mismo. Ante esta problemática surge la necesidad de desarrollar programas de intervención eficaces, capaces de lograr no sólo e…
Caracterización nutricional de la diabetes gestacional y su correlación con la evolución de la diabetes y el resultado del embarazo
2021
Los estudios recientes apuntan una relación entre un correcto modelo dietético en el embarazo y la asociación con un menor riesgo de DMG, dando una mayor prioridad en aquellas mujeres que presentan riesgo de padecer sobrepeso y/o obesidad (Tryggvadottiret al., 2015). Por este motivo, la presente Tesis se centraría en primer lugar en una recopilación de la información sobre el consumo de alimentos mediante el Cuestionario de Frecuencia de Consumo de Alimentos (CFC) (Vioqueet al., 2013)y el Test de Adhesión a la Dieta Mediterránea (TADM) (Schrödeet al., 2011) tanto en el momento del diagnóstico de la DMG como tras la intervención de Educación Diabetológica. Posteriormente se evaluará la corre…
