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.

En el presente tema se revisarán los alimentos de origen vegetal, ricos en polisacáridos y, por ello, con una función predominantemente energética. Básicamente se tienen tres grupos alimentarios: el de las legumbres y frutos secos, el de los cereales y sus derivados y el de las verduras y frutas frescas. Aunque la cultura occidental de las no los aprecia tanto, los alimentos de origen vegetal son de gran importancia en una dieta equilibrada, ya que son ricos en carbohidratos bien como fuente de energía o bien por su aporte de otros componentes como la fibra dietética. Por último, también se han incluido los hongos que se incluyen en la dieta humana debido al interés creciente de su composición nutricional.

Comparison of high hydrostatic pressure processed plus sous-vide cooked meat-based, plant-based and hybrid patties according to fat replacement
(MDPI, 2022) Janardhanan, Rasmi; González Díez, Mikel; Ibáñez Moya, Francisco C.; Beriain Apesteguía, María José; Institute on Innovation and Sustainable Development in Food Chain - ISFOOD
The impact of high-pressure processing (HPP) alone and combined with sous-vide cooking (SVCOOK) on the physicochemical and sensory traits of patties from different fat and protein matrices was evaluated. Hydro-gelled and soya emulsions were tested in meat (M), hybrid (H) and plant-based (P) patties (six formulations). M patties with pork backfat were used as reference formulation. All samples were pressurized (350 MPa, 10 min) and the HPP + SVCOOK patties were subsequently vacuum-cooked (55 °C). Significant changes (p < 0.05) in physicochemical parameters were detected in HPP and HPP + SVCOOK samples. Hardness reached the maximum value (11.0 N) in HPP treated P patties with soya emulsion. The HPP + SVCOOK M patties with backfat recorded the highest hardness (29.9 N). Irrespective of the fat formulations, the sensory characteristics of the HPP and HPP + SVCOOK M patties showed a well differentiated profile compared to H and P patties. The highest intensities for fatness, flavor, chewiness and the lowest for friability were recorded in HPP + SVCOOK M patties with backfat. The differences in physicochemical and sensory parameters of HPP + SVCOOK patties were minimal. Successful fat replacement using either one of the soya or hydro-gelled emulsion could be conducted in HPP + SVCOOK patties.

Polycyclic aromatic hydrocarbons, when present in food systems, have been shown to have a detrimental effect on human health, producing carcinogenic elements. So, the implementation of processes for their detection and identification is of vital importance. Nowadays, there are different methodologies for this purpose, but they consist of expensive and time-consuming processes. Due to their enhanced sensitivity and more accurate detection capability, metageometries operating in the terahertz band arise as a new methodology to identify and detect different chemical or biological substances. In this work, we propose a labyrinth metageometry able to detect different polycyclic aromatic hydrocarbons collected in European regulations as the most critical compounds with high experimental sensitivity. Our design is also capable to distinguish between different compounds at the same concentration. This work leads the way to the design of new metastructures able to improve the current detection limits, and thus obtain a new methodology, easier and less time-consuming that the actual methods.

(MDPI, 2021) Martínez Aldaya, Maite; Ibáñez Moya, Francisco C.; Domínguez-Lacueva, Paula; Murillo Arbizu, María Teresa; Rubio Varas, María del Mar; Soret Lafraya, Beatriz; Beriain Apesteguía, María José; Institute on Innovation and Sustainable Development in Food Chain - ISFOOD; Institute for Advanced Research in Business and Economics - INARBE
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.

Combined effect of high hydrostatic pressure, sous-vide cooking, and carvacrol on the quality of veal, plant-based, and hybrid patties during storage
(MDPI, 2023) Janardhanan, Rasmi; Olarte, Carmen; Sanz, Susana; Rota, Carmina; Beriain Apesteguía, María José; Institute on Innovation and Sustainable Development in Food Chain - ISFOOD
The effect of carvacrol added to patties stored at 4 ◦C for 14 days, previously pressurized and vacuum-cooked (HPP-SVCOOK), was investigated. Three formulations were prepared (veal, plant-based product, and hybrid product). An emulsion made with olive and linseed oils was added. The physicochemical and microbiological qualities were assessed. Microbial tests indicated negligible growth of spoilage organisms in treated patties. No significant effect of carvacrol on the microbial loads of patties was noticed. Sulfite-reducing clostridia and Enterobacteriaceae were absent in the treated patties, whereas, in the treated veal and hybrid samples, 3 and 2 units of log cfu/g reduction for lactic acid bacteria and molds and yeasts were noted, respectively. On day 7 of storage, veal patties exhibited a significant reduction (p < 0.05) in the L* (53.9–49.3), hardness (32.3–21.4 N), springiness (0.8–0.7 N), cohesiveness (0.49–0.46), and chewiness (12.2–7.1) and a hike in the a* value (5.3–9.4). No significant changes in L* (59.1–58.6), a* (8.57–8.61), hardness (11.6–10.6 N), or cohesiveness (0.27–0.26) were observed in plant-based patties over the storage times, whereas reductions in springiness (0.5–0.4), chewiness (1.9–1.3), and b* (26.6–29.1) were noted in them. In hybrid patties, the L* (53.9–52.5) and b* values (24.9–24.3) were consistent but had a significant decrease in a* value (5.9–3.5) along the days of storage under study. The texture parameters of the hybrid patties altered were similar to those of veal patties during the 14-day storage time. In all samples, pH decreased with storage time. HPP-SVCOOK was effective on rendering safe and shelf-stable, ready-to-eat patties regardless of their matrix formulation. The addition of carvacrol had limited effects on the textural qualities of the HPP-SVCOOK products. Future studies need to be undertaken to assess the treated patties’ consumer acceptability and sensory profile. The study provides the basis for the development of novel meat-based and plant-based products that are microbiologically safe, with minimum physicochemical alterations during storage.

Understanding meat quality attribute changes during ageing by using non-destructive techniques is an emergent pursuit in the agroindustry research field. Using beef certified samples from the protected geographical indication (PGI) “Ternera de Navarra”, the primary goal of this study was to use Fourier transform infrared spectroscopy on the middle infrared region (FTIR-MIR) as a tool for the examination of meat tenderness evolution throughout ageing. Samples of the longissimus dorsi muscle of twenty young bulls were aged for 4, 6, 11, or 18 days at 4 °C. Animal carcass classification and sample proximate analysis were performed to check sample homogeneity. Raw aged steaks were analyzed by FTIR-MIR spectroscopy (4000–400 cm−1) to record the vibrational spectrum. Texture profile analysis was performed using a multiple compression test (compression rates of 20%, 80%, and 100%). Compression values were found to decrease notably between the fourth and sixth day of ageing for the three compression rates studied. This tendency continued until the 18th day for C20. For C80 and C100, there was not a clear change in the 11th and 18th days of the study. Regarding FTIR-MIR as a prediction method, it achieved an R2 lower than 40%. Using principal component analysis (PCA) of the results, the whole spectrum fingerprint was used in the discrimination of the starting and final ageing days with correct maturing time classifications. Combining the PCA treatment together with the discriminant analysis of spectral data allowed us to differentiate the samples between the initial and the final ageing points, but it did not single out the intermediate points.

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).

Research on the management of broccoli crop residues and surpluses is critical for improving agricultural practices, optimizing food industrial manufacture, and contributing to better human nutrition. The objective of this study was to obtain novel ingredients based on these residues and surpluses for a wide range of applications in the food industry. The efect of air-drying (60 °C or 80 °C) applied to feld residues (broccoli stalks), mimicking industrial conditions, was compared with dehydration by freeze-drying applied to these same feld residues and to crop surpluses (broccoli whole plant). Thus, diferent broccoli fours were obtained and characterised for technological and biological properties including colour, antioxidant activity, nutrients, total polyphenol content, and content of glucosinolates. Flours from feld residues showed high levels of dietary fbre (≈22% dry weight). Broccoli crop surpluses fours had relevant contents of glucosinolates (≈13 mg/g dry weight). Therefore, within the framework of the circular economy, these fours are proposed to revalorise the two main broccoli crop discarded fractions. Such fours could be used in a realistic and simple way by the agri-food industries interested in the development of healthy and conscience foodstufs, in a cost-efcient manner.

Physicochemical and sensory assessments in Spain and United States of PGI-certified Ternera de Navarra vs. Certified Angus Beef
(MDPI, 2021) Beriain Apesteguía, María José; Murillo Arbizu, María Teresa; Insausti Barrenetxea, Kizkitza; Ibáñez Moya, Francisco C.; Cord, Christine Leick; Carr, Tom R.; Institute on Innovation and Sustainable Development in Food Chain - ISFOOD
The physicochemical and sensory differences between the PGI-Certified Ternera de Navarra (CTNA) (Spanish origin) and Certified Angus Beef (CAB) (US origin) were assessed in Spain and the USA. To characterize the carcasses, the ribeye areas (REAs), and marbling levels were assessed in both testing places. Twenty striploins per certified beef program were used as study samples. For sensory analysis, the striploins were vacuum packaged and aged for 7 days at 4◦ C and 85% RH in each corresponding laboratory. Thereafter, the samples were half cut and frozen. One of the halves was shipped to the other counterpart-testing place. The fat and moisture percentage content, Warner Bratzler Shear Force (WBSF), and total and soluble collagen were tested for all the samples. The CAB carcasses had smaller REAs (p < 0.0001) and exhibited higher marbling levels (p < 0.0001). The CAB striploins had a higher fat content (p < 0.0001) and required lower WBSF (p < 0.05) than the CTNA samples. Trained panelists rated the CAB samples as juicer (p < 0.001), more tender/less tough (p < 0.0001), and more flavorful (p < 0.0001) than the CTNA counterparts. This study shows that beef from both countries had medium-high tenderness, juiciness, and beef flavor scores and very low off-flavor scores. Relevant differences found between the ratings assigned by the Spanish and the US panelists suggest training differences, or difficulties encountered in using the appropriate terminology for defining each sensory attribute. Furthermore, the lack of product knowledge (i.e., consumption habits) may have been another reason for such differences, despite the blind sensory evaluation.
