Nutrición y dietética en el niño
(Eunate, 2017-03-01) Sánchez-Valverde, Félix; Ibáñez Moya, Francisco C.; Ciencias de la Salud; Osasun Zientziak; Institute on Innovation and Sustainable Development in Food Chain - ISFOOD
Se puede definir la infancia como el período que va desde los 1 a los 10-12 años y se puede dividir en dos etapas: preescolar, desde los 1 a 6 años (etapa en la que el niño ya posee autonomía en la marcha), y escolar, desde los 6 a 10-12 años (etapa prepuberal). Aunque es usual el considerarlos separadamente, en el presente tema se va a hacer de modo conjunto indicándose solamente algunos aspectos específicos en relación a la edad. El crecimiento y desarrollo físicos que tienen lugar durante este período vital están relacionados y afectan directa o indirectamente a las pautas alimentarias. Así, por ejemplo, en torno a los 3 años termina la erupción dental decidua y la maduración de los procesos metabólicos y funciones digestivas son tales que permiten al niño una dieta variada.

High hydrostatic pressure processing to replace texturizing agents on a plant product intended for altered deglutition: a concept proof
(Elsevier, 2023) Fernández Pan, Idoya; Merino Antón, Gorka; Virseda Chamorro, Paloma; Beriain Apesteguía, María José; Ibáñez Moya, Francisco C.; Institute on Innovation and Sustainable Development in Food Chain - ISFOOD; Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa
High hydrostatic pressure processing (HPP) can cause changes in food texture. These changes can be beneficial when developing food with strict texture specifications as it is the case of food targeted to people with altered deglutition (AD) issues. The aim of the present research was to evaluate the HPP potential as an alternative to the use of texturizing agents currently added to AD-targeted food products. First, formulation and experimental conditions of treatments were established, and 2 types of chickpea protein pur´ees, one containing corn starch (PS) and the other chicory inulin (PI), were developed. Second, the pur´ees were, in one case HPP-treated (300–400 MPa; 3–9 min) and in the other texturized with agar-agar and xanthan gum. Overall, HPP did not significantly affect the proximate composition of the purées and improved their microbiological quality, and, most importantly, they caused beneficial texture changes on both PS and PI purées. In addition, HPP-treatments conferred similar instrumental texture values to texturized purées. These texture values come within the given specific range data supplied by the literature for AD suitability. The present study provides the basis for applying HPP in the development of texturizer-free AD-oriented purées.

Lycopene is usually extracted from the by-product of the tomato industry using organic solvents (OS) in combination with a physical technique. An emerging physical technique is high-pressure processing (HPP). This study aims to find a method by applying a green solvent (edible vegetable oils) in an HPP-assisted solid-liquid extraction. Three dosages of tomato by-product (10%, 20%, and 40%, w/v) were tested using OS, sunflower oil (RSO), and extra-virgin olive oil (EVOO). Lycopene recovery increased with the ratio of by-product to oil, particularly when using EVOO. In another stage of the study, consumers evaluated EVOO that contained two doses of tomato by-product (10% and 20%, w/v). Consumers preferred the EVOO from 10% tomato by-product ratio over that with 20%. Additionally, 83.8% of consumers stated that enriched oil could be deemed beneficial for health. The proposed method considers the fundamental principles of the circular economy and practical industrial scenario to recover lycopene from tomato by-product.

El gasto energético: estimación por calorimetría indirecta y fórmulas
(Eunate, 2024) Ibáñez Moya, Francisco C.; Agronomía, Biotecnología y Alimentación; Agronomia, Bioteknologia eta Elikadura
Las necesidades energéticas totales requeridas por un individuo adulto vienen determinadas principalmente por el metabolismo basal, la termogénesis inducida por los alimentos ingeridos y la actividad física. Cada uno de estos componentes lleva parejo un gasto energético. Siendo el gasto energético del metabolismo basal (GMB) el componente de mayor contribución al gasto energético total, y puesto que con fines prácticos se usan los métodos indirectos, es necesario familiarizarse con dos técnicas para su cuantificación.

El estado nutricional (4): composición corporal mediante análisis por bioimpedancia
(Eunate, 2017-03-01) Ibáñez Moya, Francisco C.; Arana Azparren, María Inés; Irigoyen Moriana, Aurora; Ciencias de la Salud; Osasun Zientziak
La aplicación de una corriente eléctrica alterna y constante en las estructuras biológicas produce una oposición al paso de la misma, llamada impedancia (Z), que depende, a su vez, de la frecuencia de la corriente eléctrica aplicada. Esta Z se puede definir como un vector de dos componentes, la reactancia (Xc) y la resistencia (R): 𝑍 = √𝑋c2 + 𝑅2 Otro componente del vector Z es el ángulo de fase (¿). Este parámetro del ¿ se está usando a nivel clínico porque es un indicador de la integridad celular: valores bajos indican lesión o muerte celular, mientras que valores altos se asocian a membranas celulares íntegras. La reactancia se relaciona con la capacidad de las estructuras biológicas para disipar la energía y la resistencia con la capacidad de almacenar la energía.

Dishes adapted to dysphagia: sensory characteristics and their relationship to hedonic acceptance
(MDPI, 2021) Merino Antón, Gorka; Marín Arroyo, Remedios; Beriain Apesteguía, María José; Ibáñez Moya, Francisco C.; Institute on Innovation and Sustainable Development in Food Chain - ISFOOD; Gobierno de Navarra / Nafarroako Gobernua
Dishes whose texture has been modified for dysphagia undergo changes in other sensory characteristics as well. Therefore, it is necessary to identify these characteristics in adapted dishes and their relationship to hedonic acceptance. In the present work, the sensory characteristics of five dishes adapted to dysphagia associated with cerebral palsy were investigated using the check-all-that-apply method. A hedonic evaluation with a panel of non-dysphagic judges was performed to relate the degree of acceptance with the sensory characteristics of the adapted dishes. The identification of the original non-adapted dish as well as the relationship between the hedonic evaluation by nondysphagic judges and dysphagic judges were explored. The main attributes of the dishes adapted to dysphagia were “homogeneity” and “easy-to-swallow”. Attributes that increased the hedonic evaluation were “flavorful”, “flavor of the original dish”, “soft texture”, “easy-to-swallow”, and “odor of the original dish”. The attributes that decreased the hedonic evaluation were “thick mash” and “bland”. The fish dish was the only one correctly identified more than 62.5% of the time. The adapted dishes received scores above 4.7 out of 9.0 in the hedonic evaluation. The most accepted dishes were the chicken stew and the chickpea stew. Except for the pasta dish, the test yielded similar results to those obtained with dysphagic judges. The texture-modified dishes were correctly characterized and accepted. This study shows that all the sensory characteristics of the adapted dishes are crucial for acceptance and identification.

Aspectos nutricionales de los elementos minerales y del agua
(Eunate, 2024) Eseberri Barace, Itziar; Ibáñez Moya, Francisco C.; Agronomía, Biotecnología y Alimentación; Agronomia, Bioteknologia eta Elikadura; Institute on Innovation and Sustainable Development in Food Chain - ISFOOD
En los seres vivos, además de los elementos químicos que constituyen la materia orgánica (carbono, oxígeno, hidrógeno y nitrógeno), existen otros que forman parte de la composición de aquellos o de la materia inorgánica, aunque en pequeñas cantidades. A tales elementos se les denomina elementos minerales, y sólo se pueden obtener a través de la dieta. Los elementos minerales se clasifican atendiendo a las cantidades en las que son necesarias diariamente para los humanos y en las cantidades en las que aparecen en el cuerpo. La figura 1 recoge una propuesta para su clasificación atendiendo a sus necesidades, dividiéndolos en macrominerales (más de 100 mg), microminerales u oligoelementos (menos de 100 mg), elementos traza (generalmente entre 1µg y 1 mg) y elementos ultratraza (cuyas cantidades exactas y funciones suelen ser desconocidas). Hay que decir que esta clasificación ni refleja la importancia nutricional de los elementos, ya que la deficiencia de un elemento que se requiere en ínfimas cantidades puede ser tanto o más perjudicial que la causada por otro elemento que se requiere en grandes cantidades, ni está aceptada por toda la comunidad científica, pues hoy en día todavía se dan diferentes clasificaciones en función de distintos autores.

Textural characteristics of safe dishes for dysphagic patients: a multivariate analysis approach
(Taylor & Francis, 2019) Ibáñez Moya, Francisco C.; Gómez Bastida, Inmaculada; Merino Antón, Gorka; Beriain Apesteguía, María José; Institute on Innovation and Sustainable Development in Food Chain - ISFOOD; Gobierno de Navarra / Nafarroako Gobernua
Twenty-four safe dishes for cerebral palsy dysphagic patients and four commercial dysphagia-oriented food products for dysphagia were studied in order to determine their textural characteristics. Apparent viscosity measured at 25, 50, and 100 s(-1) and extrusion force analyzed at 1, 2, 5, and 10 mm/s were evaluated. Using clustering techniques, samples were divided into three categories. Apparent viscosity at 50 s(-1) and extrusion force at 5 and 10 mm/s could be enough to characterize the safe dishes for dysphagic patients.

The reformulation of a beef patty enriched with n-3 fatty acids and vitamin D3 influences consumers' response under different information scenarios
(MDPI, 2020) Beriain Apesteguía, María José; Gómez Bastida, Inmaculada; Sánchez García, Mercedes; Insausti Barrenetxea, Kizkitza; Sarriés Martínez, María Victoria; Ibáñez Moya, Francisco C.; Institute on Innovation and Sustainable Development in Food Chain - ISFOOD
The objective of this study was to investigate the sensory acceptability and willingness to pay (WTP) for a beef patty elaborated with beef from a local breed that was enriched with nutritional ingredients (vegetable oil mixture and vitamin D3). The experiment was conducted under two information scenarios (blind; full: ingredients used to enrich the patties in n-3 PUFA and vitamin D3). An in-home use test was carried out by 180 consumers to study consumer liking of two low-fat beef patties (C: conventional, M: modified). There were no differences in color and odor for the raw patties (p> 0.05). The sensory parameters of the cooked patties were assessed as being similar (p > 0.05) regardless of the information scenario. The sensory parameters remained crucial criteria for product acceptance and repeat purchase. Consumers positively evaluated the M patty. The information provided to consumers on the composition of the product influenced the response of consumers. It was also observed that the higher the education level of the consumer, the higher their scores for M beef patties in the blind scenario. It is thus necessary to implement appropriate marketing strategies in order to highlight the nutritional properties of the modified patties, making them competitive ahead of conventional patties.
