Study of thermal resistance and in vitro bioaccessibility of patulin from artificially contaminated apple products
2012
Abstract Apple juices and purees represent categories widely consumed by whole population and above all children. Patulin (PAT) is a mycotoxin known for its acute and chronic effects in animals. Several studies indicate there is a risk associated to the PAT intake, through the consumption of purees and apple juices. In this study, apple juice and puree were prepared and artificially contaminated with PAT at 50 μg/kg and submitted to a thermal treatment simulating pasteurization to evaluate PAT’s reduction. In a second phase of the work, apple products samples ( n = 7) included juices, nectars and purees belonging to different commercial brands were collected, artificially contaminated with…
Exploring the use of low-intensity ultrasonics as a tool for assessing the salt content in pork meat products
2015
Meat industry demands non-destructive techniques for the control of the salting process to achieve a homogeneous final salt content in salted meat products. The feasibility of using low-intensity ultrasound for characterizing the salting process of pork meat products was evaluated. The ultrasonic velocity (V) and time of flight (TF) were measured by through-transmission and pulse-echo methods, respectively, in salted meat products. Salting involved an increase of the V in meat muscles and a decrease of the time of flight in whole hams. Measuring the V before and after salting, the salt content could be estimated. Moreover, online monitoring of the salting process by computing the TF could b…
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…
Postnatal programming cardiometabolic risk : effects of moderate caloric restriction in adulthood
2016
Postnatal overfeeding (PNOF) in rodents induces early programming of cardio-metabolic risk. Our aim was to determine if a moderate diet restriction could restore cardio-metabolic alterations induced by PNOF.Immediately after birth, litters of C57BL/6 mice were either maintained at 9 (normal litter, NL), or reduced to 3 (small litter, SL) to induce PNOF. At weaning, all mice received a standard diet ad libitum (AL). At 6 month of age, half of the NL and SL mice were assigned to a moderate 20% calorie restriction (CR: NLCR, SLCR) for one month, while the other mice continued to eat AL (AL: NLAL, SLAL). Glucose and insulin tolerance tests, cardiac function (echocardiography), body composition …
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 …
Functional and bioactive properties of peptides derived from marine side streams
2021
In fish processing, a great amount of side streams, including skin, bones, heads and viscera, is wasted or downgraded as feed on a daily basis. These side streams are rich sources of bioactive nitrogenous compounds and protein, which can be converted into peptides through enzymatic hydrolysis as well as bacterial fermentation. Peptides are short or long chains of amino acids differing in structure and molecular weight. They can be considered as biologically active as they can contribute to physiological functions in organisms with applications in the food and pharmaceutical industries. In the food industry, such bioactive peptides can be used as preservatives or antioxidants to prevent food…

Fruit physical, chemical and aromatic attributes of early, intermediate and late apricot cultivars.
2010
BACKGROUND: In order to reach good fruit quality, apricots require a balance of sugars and acids as well as a strong apricot aroma. In this study, fruit quality of early, intermediate and late apricot cultivars was evaluated by measuring physical, chemical and olfactory attributes. Multivariate analysis of quality and aroma attributes was used to identify groups of similar cultivars and association with ripening season. RESULTS: Physical, chemical and aromatic attributes showed great variation amongcultivars but no relation to ripening season. Aromatic profiles (34 volatiles) of fruit tissues indicated qualitative and quantitative differences among cultivars. Ninfa and Mandorlon were riches…
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…
