    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

    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%.
