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 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.

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.

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.

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.

A methodology to adapt dishes for cerebral palsy (CP) dysphagic people was developed. Five conventional dishes were cooked, blended and texturized with mixtures of thickeners and gelling agents based on xanthan gum. The most appropriate texturizing agents were selected, the textural thermostability of the dishes was studied, and the shelf-life was evaluated by back extrusion, sensory and microbiology analysis. Information about the acceptability of the adapted dishes by CP dysphagic people was obtained through the control of the consumed fraction and the liking or disliking reaction after eating the dishes. The adapted dishes considered suitable for swallowing process showed maximum force between 6.2(0.1) N and 18.9(3.3) N, minimum force between −3.9(0.3) N and −9.2(1.3) N, and Fmin/Fmax ratio between 0.4(0.0) and 0.7(0.0). Regarding sensory characteristics, the adapted dishes showed low stickiness, residue and firmness, and high suitable texture score. The methodology was appropriate for developing suitable dishes, sensorially accepted by dysphagic people, thermostable for 7 days refrigerated storage and ready-to-eat. Industrial relevance: This study presents the technological basis for the standardized design of suitable ready-to-eat dishes for dysphagic people. The methodology developed is of great interest to the industry of ready-to-eat dishes.

Weissella cibaria is a lactic acid bacteria that has been receiving great interest in the last decade; however, its research into aquaculture remains insufficient. In this context, the resistance to pH 3–5, bile salts (10–20%), hydrophobicity, and carbohydrate metabolisms of two W. cibaria strains isolated from rainbow trout were evaluated. At the same time, the postbiotic products of both W. cibaria were produced under different conditions, and their stability to heat (95–130 °C) and proteolytic enzymes were determined. The low pH sensitivity of two pathogens (Aeromonas salmonicida subsp. salmonicida and Yersinia ruckeri) was also recorded. Both strains of W. cibaria survived pH and bile salt treatments. Neither expressed enzymatic activity or hydrophobic characteristics with the executed methods. Treatment with heat, enzymes, and transfer to vegetal broth significantly reduced (p < 0.05) the postbiotic product’s antibacterial activity. On the other hand, no significant difference (p < 0.05) was reported in antibacterial characteristics when postbiotics were produced by coculturing both strains. Low pH does not significantly influence pathogen growth (p < 0.05). Our findings suggest that the studied strains do not adjust as probiotics, but the postbiotic product obtained from them could become a promising tool as a supplement food for fish aquaculture applications.

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.

Research coupling human nutrition and sustainability concerns is a rapidly developing field, which is essential to guide governments' policies. This critical and comprehensive review analyzes indicators and approaches to 'sustainable healthy diets' published in the literature since this discipline's emergence a few years ago, identifying robust gauges and highlighting the flaws of the most commonly used models. The reviewed studies largely focus on one or two domains such as greenhouse gas emissions or water use, while overlooking potential impact shifts to other sectors or resources. The present study covers a comprehensive set of indicators from the health, environmental and socio-economic viewpoints. This assessment concludes that in order to identify the best food option in sustainability assessments and nutrition analysis of diets, some aspects such as the classification and disaggregation of food groups, the impacts of the rates of local food consumption and seasonality, preservation methods, agrobiodiversity and organic food and different production systems, together with consequences for low-income countries, require further analysis and consideration.

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.
