La innovación es un factor clave para impulsar y consolidar el sector cárnico, incrementando la competitividad en la cadena de carne de vacuno y garantizando a los consumidores los mejores productos, sanos y de calidad. El objetivo general planteado en la presente Tesis Doctoral ha sido estudiar el efecto de la incorporación de ingredientes ricos en ácidos grasos poliinsaturados n-3 y CLA en las dietas de cebo de terneros con objeto de mejorar la calidad nutricional y organoléptica de su carne en función de las preferencias de los consumidores nacionales y posibilitar la obtención de nuevos derivados cárnicos saludables. Se utilizaron 48 machos enteros Holstein de 150 kg de peso vivo que fueron alimentados con 4 dietas experimentales (12 animales por tratamiento): 1. CONTROL: pienso concentrado comercial enriquecido. 2. LINO: CONTROL con un 10% de lino. 3. CLA: CONTROL con un 2% de CLA. 4. LINO+CLA: CONTROL con un 10% de semilla de lino y 2% de CLA. El sacrificio se realizó cuando los animales alcanzaron 450 kg de peso vivo (10- 11 meses de edad). A las 24 horas del sacrificio se procedió a la toma de muestras del músculo Longissimus Dorsi, que posteriormente fueron congeladas hasta la realización de los diferentes análisis y experimentos que se han llevado a lo largo de la tesis. El enriquecimiento con un 10% de semilla de lino y 2% de CLA de las dietas, que no ha afectado a los parámetros productivos ni metabolismo del tejido adiposo, ha mejorado el perfil de ácidos grasos de la carne, adecuándose más a los requerimientos nutricionales de los consumidores. Asimismo, esta carne enriquecida ha mejorado su calidad organoléptica en función de las preferencias de los consumidores nacionales y ha presentado una buena aptitud tecnológica. Finalmente, se puede concluir que la inclusión de semilla de lino y CLA en las dietas de terneros Hosltein puede mejorar la calidad nutricional y sensorial de la carne, sin afectar negativamente al metabolismo del animal ni a la aptitud tecnológica de las carnes obtenidas.

(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 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.

Methodology for design of suitable dishes for dysphagic people
(Elsevier, 2020) Merino Antón, Gorka; Gómez Bastida, Inmaculada; 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, PEP E-14/000107-01
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.

Chistorra de Navarra: un embutido tradicional enraizado en expansión
(Estrategias Alimentarias, 2022) Beriain Apesteguía, María José; Gómez Bastida, Inmaculada; Institute on Innovation and Sustainable Development in Food Chain - ISFOOD
La chistorra es un producto cárnico de tradición gastronómica navarra. Para la defensa y promoción de este producto, el Gremio de Carniceros organiza periódicamente un concurso donde se elige la mejor chistorra de Navarra. Esta elección es llevada a cabo de manera rigurosa por un panel de expertos que evalúa sensorialmente las chistorras elaboradas por diferentes artesanos de la comunidad. Durante años, fruto de la colaboración entre la Universidad Pública de Navarra (UPNA) y el Gremio de Carniceros, se han realizado estudios para contribuir al reconocimiento y desarrollo e incentivar la mejora de la calidad y del consumo de la chistorra que se produce en Navarra. Estos estudios se han realizado sobre muestras representativas de las chistorras participantes en los concursos, en las que se han evaluado además de la calidad sensorial, parámetros físicoquímicos y nutricionales. La necesidad de adaptarse a las tendencias actuales del mercado podría poner en peligro la fórmula tradicional, alejando así a la chistorra de las características propias tradicionales que la definen. Por ello es importante determinar los estándares de la chistorra actual y crear una marca de calidad como la Indicación Geográfica Protegida (IGP).

Raw-cured Spanish traditional meat product 'Chistorra de Navarra': sensory and composition quality standards
(MDPI, 2020) Beriain Apesteguía, María José; Murillo Arbizu, María Teresa; Insausti Barrenetxea, Kizkitza; Sarriés Martínez, María Victoria; Gómez Bastida, Inmaculada; Institute on Innovation and Sustainable Development in Food Chain - ISFOOD
The aim of this work was to set the quality standards of the chistorra de Navarra, a raw-cured Spanish traditional meat product, through the study of its sensory and physicochemical features. The quality of chistorra samples, coming from 50 different artisan producers, were assessed during three sessions by expert assessors (n = 15). In the first session, instrumental colour (L*a*and b*) and appearance and odour parameters were evaluated in the raw products. In the second session, texture and flavour attributes were determined in cooked products. Finally, in the third session, the best 10 classified chistorras from the first and second sessions were sensorially evaluated and sampled for further analysis: texture (Warner Bratzler and texture profile analysis (TPA)), chemical composition, and fatty acid profile. The chistorras with the highest sensory scores had high shear force values, flavour intensity, and fat/hydroxyproline ratio. The average fatty acid profile obtained for chistorra de Navarra was: 42% saturated fatty acids (SFA), 45% monounsaturated fatty acids (MUFA), and 13% polyunsaturated fatty acids (PUFA), which was similar to the one found in other raw-cured sausages. Considering the sensory evaluation, chistorra was defined as a product with an intense orange colour, and with high resistance value in the initial bite. It was also characterised by a high juiciness and tenderness, aroma, and meat flavour. In mouth, the pork fat, one of the ingredients of chistorra, was balanced without any of the ingredients dominating. Chemically, the chistorra was characterised by a fat content close to 67% (dry matter), low hydroxyproline occurrence (≤0.6), and protein amount ranging 18 38%.

Shelf life of ground beef enriched with omega-3 and/or conjugated linoleic acid and use of grape seed extract to inhibit lipid oxidation
(Wiley, 2016) Gómez Bastida, Inmaculada; Beriain Apesteguía, María José; Mendizábal Aizpuru, José Antonio; Realini, Carolina; Purroy Unanua, Antonio; Ciencias del Medio Natural; Natura Ingurunearen Zientziak; Producción Agraria; Nekazaritza Ekoizpena
The shelf life and oxidative stability of refrigerated raw ground beef enriched with omega-3 and/or conjugated linoleic acid (CLA) were studied. Grape seed extract (GSE) was used to inhibit lipid oxidation in the ground beef. Eight treatments of ground beef were established according to the enrichment of beef (control, enriched with omega-3, with CLA, or with omega-3 plus CLA) and the use of GSE (0 and 250 mg GSE/kg product). Fresh beef was ground and mixed with GSE and salt. Treatments of beef were stored at 2± 1°C in aerobic packaging for 0, 1, 3, and 6 days under retail display conditions. Oxidation stability (thiobarbituric acid-reactive substances [TBARS]), pH, instrumental color, metmyoglobin formation, and sensory attributes (color and odor) were measured. Omega-3-enriched beef increased the oxidation level at day 6 as determined by TBARS (P<0.05), but the instrumental color was not affected. The enrichment of CLA improved the coordinates of color (P<0.05) until day 3 and decreased the oxidation at day 6 (P<0.05). There were no differences in color and odor values among the types of beef during display, except at day 3, when CLA treatments had the highest scores. Addition of GSE decreased the oxidation level (P<0.001) and did not affect the instrumental color or the sensory parameters.

Physicochemical and sensory properties of sous vide meat and meat analog products marinated and cooked at different temperature-time combinations
(Taylor & Francis, 2019) Gómez Bastida, Inmaculada; Ibáñez Moya, Francisco C.; Beriain Apesteguía, María José; Institute on Innovation and Sustainable Development in Food Chain - ISFOOD
Ready-to-eat (RTE) products elaborated from beef and meat analog, previously marinated (teriyaki and beer), were subjected to sous vide cooking at different combinations of temperature (70ºC and 80ºC) and time (60, 90 and 120 min for beef; 90, 120 and 150 min for meat analog). The sous vide cooking at 80ºC led to less cooking losses. The shear force values were approximately 50% lower in meat analog samples than in beef samples. The L* and a* value and sensory properties related to odor and color were similar in meat and meat analog products.
