Potential application of lactic acid bacteria in the biopreservation of red grape from mycotoxigenic fungi

2021

Background Filamentous fungi are the main contamination agent in the viticultural sector. Use of synthetic fungicides is the regular answer to these contaminations. Nevertheless, due to several problems associated with the use of synthetic compounds the industry demands new and safer methods. In the present work, the biopreservation potential of four lactic acid bacteria (LAB) strains was studied against the principal grape contaminant fungi. Results Agar diffusion test evidenced that all four culture-free supernatant (CFS) had antifungal properties against all tested fungi. The Minimum Inhibitory Concentration (MIC) and Minimum Fungicidal Concentration (MFC) test values evidenced that medi…

Presence of palm oil in foodstuffs: consumers' perception

2019

Purpose The purpose of this paper is to determine the presence of palm oil in food products on sale, and to study and compare consumers’ opinions about this oil type in Spain (importing country) and Peru (producing country). Design/methodology/approach Recent news published in both countries, which could influence consumer perceptions, were analysed. A study on the labelling of foodstuffs in Spain was carried out, as was a survey with Spanish and Peruvian consumers. Findings Palm oil was found in a large number of products and in a wide range of foods, especially those from the bakery sector. The percentages of saturated fats varied substantially within the same product type. Spanish consu…

Kinetics of ascorbic acid degradation in fruit-based infant foods during storage

2013

The kinetics of ascorbic acid (AA) degradation in a fruit-based beikost product added with AA were determined after storage at 4, 25, 37 and 50 °C during 4, 8, 12, 16 and 32 weeks in plastic polypropylene/ethylenevinyl alcohol vacuum packaging. It was confirmed that AA degradation followed an Arrhenius first-order kinetics, with an activation energy of 20.11 ± 0.33 kcal mol−1. No AA losses at 4 °C were recorded during the entire storage period. In contrast, a time - and temperature - dependent decrease (p the degradation rate decreasing from 50 °C to 25 °C, as expected. AA percentage retention at the end of storage ranged between 6.4% (50 °C/16 weeks) and 100.9% (4 °C/32 weeks).

Applying systematic review search methods to the grey literature: a review of education and training courses on breastfeeding support for health prof…

2021

Abstract Background Currently, lactation training courses aimed at health professionals are important for informing and supporting mothers who are breastfeeding. In this review, we seek to analyze similarities and/or variations in course content, modes of delivery, costs, teaching style and learning strategies among courses. To our knowledge, a review of lactation training courses available worldwide is lacking. Thus, the aim of this review is to describe course models aimed at training health professionals in lactation support for mothers. Methods Through searching grey literature, training courses were obtained from several directories, including the Alaska Breastfeeding Coalition, Intern…

Prebióticos y nucleótidos en alimentación infantil: revisión de la evidencia

2012

Introducción: Una gran mayoría de preparados infantiles de inicio y continuación comercializados en España presentan en su formulación prebióticos y/o nucleótidos, con objeto de lograr efectos beneficiosos en la prevención de diferentes patologías y protección inmunológica, similares a los de la leche materna. No obstante, atendiendo a la reglamentación vigente, su adición es opcional, ya que no existe suficiente evidencia científica que certifique la obligatoriedad de su inclusión. Objetivo: Revisar sistemáticamente la evidencia científica proveniente de estudios clínicos aleatorizados con grupo control que permita determinar el papel beneficioso para la salud de los lactantes derivada de …

Edma 0-6 : educación matemática en la infancia

2018

There are numerous studies that support the interest of starting the development of algebraic thinking in Primary School. In this paper, we present a part of a research project aimed to explore the processes of solution of geometric pattern problems by students in Primary grades 4th to 6th. We analyze the behavior of students who were administered a teaching unit based on the resolution of this type of problems in the GeoPattern application, created by the authors for this purpose. A characteristic of the application is that it informs the students on the correctness of their answers and allows them to respond again to the same question when their answer was wrong. This causes the students …

La evaluación del aprendizaje: de la retroalimentación a la autorregulación. El papel de las tecnologías.

2015

Este artículo recoge una revisión sobre la evaluación en el ámbito universitario focalizada sobre la información que se aporta a los estudiantes a partir del análisis de sus resultados de aprendizaje. Para ello, define conceptos como retroalimentación, proalimentación y autorregulación del aprendizaje y los sitúa dentro del proceso de evaluación. Tras segmentar dicho proceso en sus componentes fundamentales, este trabajo se detiene en la relación entre el modo en que se aporta información sobre la evaluación (con especial atención al papel de las TIC) y la forma en que dicha información se utiliza por parte de los estudiantes, considerando variables que afectan a sus antecedentes académicos…

Alimentació a l'Eivissa púnica (segles V a II a.E.)

2015

L’objecte d’estudi d’aquesta tesi ha estat la recerca sobre els diferents patrons alimentaris tant en una geografia com una cronologia molt concreta: l’illa d’Eivissa durant els segles V al II, en el període denominat púnic clàssic i tardà. L’abundant informació arqueològica, així com les fonts clàssiques, han sigut essencials per discernir les diverses conductes nutricionals segons els diversos àmbits i períodes analitzats. Igualment, hem prestat especial atenció als estudis específics sobre la fauna, les analítiques de continguts de recipients ceràmics i els isòtops estables a ossos humans. No hem dubtat en recórrer a altres situacions paral·leles que podem trobar en altres jaciments púni…
