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.

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 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.

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.

Mid-infrared spectroscopy (MIR) for simultaneous determination of fat and protein content in meat of several animal species
(Springer, 2017) Lozano Saiz, María; Rodríguez Ulibarri, Pablo; Echeverría Morrás, Jesús; Beruete Díaz, Miguel; Sorolla Ayza, Mario; Beriain Apesteguía, María José; Institute of Smart Cities - ISC; Institute on Innovation and Sustainable Development in Food Chain - ISFOOD; Institute for Advanced Materials and Mathematics - INAMAT2
The aim of this research was to study the application of MIR spectroscopy as an alternative to conventional methods to determine fat and protein content. Samples of the main species used to produce meat products were analyzed, showing all of them absorption bands at similar wavenumbers though with different intensity. Correlation analysis of absorption intensities showed that bands around 2925, 2854, and 1746 cm−1 are associated with fat content, whereas bands around 3288, 1657, and 1542 cm−1 are associated with proteins. During the validation process, prediction models of fat and protein content were successfully obtained withR2 0.9173 and 0.7534, respectively. Finally, a good result (R2 =0.8829) was obtained on the estimation of the lipid content when the information at only one wavenumber was used.

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.

Instrumental colour measurement as a tool for light veal carcasses online evaluation
(Copernicus Publications, 2013) Horcada, Alberto; Juárez, Manuel; Molina, Antonio; Valera, Mercedes; Beriain Apesteguía, María José; Ciencias del Medio Natural; Natura Ingurunearen Zientziak
Eight-hundred and forty-five veal carcasses (535 males and 310 females) from Pirenaica breed and its crosses with Charolais and Limousin were used to compare carcass colour visual assessments 60min post-mortem with the values obtained using a spectrocolorimeter (CIE Lab colour system) on the pectoralis superficialis muscle. Carcass weights ranged between 240 and 360 kg. Visual colour was subjectively evaluated by two trained assessors. The best correlation between visual appraisal and L* was observed in carcasses of 300-320 kg. A relatively strong correlation between visual appraisal and a* values was observed in carcasses of 280-300 kg of weight. However, the correlation between b* and visual appraisal was low. Using discriminant functions that included L* and a*, the spectrocolorimeter classified correctly 60% of carcasses in the class colour assigned by the assessors. In fact, 99% of male and 96% of female carcasses were correctly assigned in the most common colour of veal carcasses in the Spanish market (»pink«, 5). These results indicate that online instrumental colour measurements on pectoralis superficialis muscle could be recommended to objectively evaluate carcass colour of commercial veal for the Spanish market.

The aim of this work was to investigate the feasibility of near-infrared spectroscopy (NIRS), combined with chemometric techniques, to detect fraud in minced lamb and beef mixed with other types of meats. For this, 40 samples of pure lamb and 30 samples of pure beef along with 160 samples of mixed lamb and 156 samples of mixed beef at different levels: 1-2-5-10% (w/w) were prepared and analyzed. Spectral data were pre-processed using different techniques and explored by a Principal Component Analysis (PCA) to find out differences among pure and mixed samples. Moreover, a PLS-DA was carried out for each type of meat mixture. Classification results between 78.95 and 100% were achieved for the validation sets. Better rates of classification were obtained for samples mixed with pork meat, meat of Lidia breed cattle and foal meat than for samples mixed with chicken in both lamb and beef. Additionally, the obtained results showed that this technology could be used for detection of minced beef fraud with meat of Lidia breed cattle and foal in a percentage equal or higher than 2 and 1%, respectively. Therefore, this study shows the potential of NIRS combined with PLS-DA to detect fraud in minced lamb and beef.

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.
