Evaluación del contenido del aminoácido no proteico ácido beta-3-N-oxalil-L-2,3 diaminopropiónico (beta-ODAP) en almortas (Lathyrus sativus L.) conservadas en el Banco de Germoplasma Hortícola del CITA
Get PDFLa almorta (Lathyrus sativus L.) es una especie leguminosa con un alto contenido en proteína. Se trata de un cultivo muy rústico, adaptado a escenarios de sequía y suelos pobres, que es considerado como una planta modelo para sistemas de agricultura sostenible. Por ello, desde el proyecto “Siembra Teruel” se está impulsando su cultivo. Según la AECOSAN, el consumo de almorta para alimentación humana se considera seguro cuando el contenido en el aminoácido no proteico beta-ODAP reducido es inferior a un 1 %, en el marco de una dieta variada. En el presente trabajo se analiza el contenido en beta-ODAP en el grano seco de 5 muestras procedentes de la provincia de Teruel, y se compara con muestras de otros orígenes (Cuenca, Italia y Portugal). Aunque mayoritariamente la almorta se consume utilizando la harina obtenida del grano seco, como gachas o farinetas, también se pueden realizar otras recetas. Por ello, en el trabajo se analizan adicionalmente muestras susceptibles de ser utilizadas para el consumo (vaina verde, grano verde, grano precocido y seco). Los resultados muestran un contenido de beta-ODAP inferior al 1% sobre materia seca (sms) en todas las muestras analizadas, excepto para la vaina verde. Los contenidos de las muestras de Teruel varían entre 0,297% y 0,446%, valores superiores a los de las almortas de Italia y Portugal (0,190% y 0,261%, respectivamente) y similares a los de Cuenca (0,314%). En comparación con el grano seco (0,389%), los contenidos de la vaina y el grano en verde son superiores (1,054% y 0,625%, respectivamente) mientras que el de grano precocido y seco (0,217%) y el de la harina (0,256%) son inferiores.El trabajo se enmarca en el proyecto “Siembra Teruel”, del Fondo de Inversiones de Teruel (FITE), financiado por Gobierno de Aragón y Gobierno de España. Las accesiones han sido cultivadas en una parcela experimental de Muniesa en colaboración con los agricultores Félix Yus y Víctor Yus. La muestra de grano precocido y seco ha sido obtenida por Belén Soler (La Ojinegra, Alloza, Teruel).Publishe

Strategies for Porcine Liver Valorization as a Source of Food Ingredients
Get PDFPurpose of Review
The sustainable consumption and production goal and the decline of offal consumption have led to the interest in seeking alternatives for porcine livers, the largest edible gland. To that aim, we reviewed the potential of porcine livers as a source of food ingredients together with the use of eco-innovative processes and technologies for their valorization.
Recent Findings
It is possible to extract and transform various compounds and fractions into food ingredients with tailored techno-functional properties using eco-innovative strategies involving microbial, enzymatic, physical, and chemical processes. These strategies can also contribute to improving the efficacy of different extraction and transformation processes as well as enhance sensory properties.
Summary
Porcine liver is an interesting source of valuable compounds with multiple food applications and health benefits. Through extraction, processing, and transformation, these compounds can yield versatile food ingredients, thereby optimizing the profitability of this resource for human consumption through alternative presentations and potentially diminishing consumer reluctance compared to the whole liver.This work was funded by the Spanish Ministerio de Ciencia e Innovación and the Agencia Estatal de Investigación [10.13039/501100011033], grant numbers RTA2017-00024 (coordinated projects C01 to C04) and PDC2021-121822 (coordinated projects C21-C22), and by the “European Union NextGenerationEU/PRTR”.Bioactive peptidesProtein hydrolysatesTechno-functional propertiesAntioxidant activityPublishe

The Information Value of Geographical Indications
No full textWe conduct laboratory experiments in Spain (N = 148) and France (N = 143) simulating a wine shopping experience in which participants choose between four wines in a limited information environment, and access to Geographical Indication (GI) information, winery names, and expert review scores are “purchased” in multiple price listing elicitation sessions. Data analysis leverages the sequential nature of the rounds, experimental treatments, and a wine knowledge questionnaire to investigate the hierarchical structure and level of redundancy between alternative information sources, the role played by wine prices, and previously acquired expertise. We estimate that the average value of accessing GI information in a pre-purchase scenario lies between EUR 0.33 (Spain) and EUR 0.37 (France) for each purchasing occasion, and expert reviews provide a similar level of information. These findings are consistent across different price segments (high: €13-€17 vs. low: €4-€7). Firm names have lower average valuation but are more useful to high-knowledge consumers. GIs, firm names, and expert reviews are found to be imperfect substitutes, suggesting that GIs capture elements of both horizontal and vertical differentiation. The discussion is structured along three main thematic areas of contribution: the role of GIs as signals of quality, the extant literature studying how consumers interpret quality signals, and the contrast between our findings and the modeling assumption adopted in the GI theoretical literature.This work was supported by the Gobierno de Aragón under the funding of the “Economía Agroalimentaria y de los Recursos Naturales” (S01_20R) Research Group.

Disruption of Erythritol Catabolism via the Deletion of Fructose-Bisphosphate Aldolase (Fba) and Transaldolase (Tal) as a Strategy to Improve the Brucella Rev1 Vaccine
Get PDFBrucellosis is a bacterial zoonosis caused by the genus Brucella, which mainly affects domestic animals. In these natural hosts, brucellae display a tropism towards the reproductive organs, such as the placenta, replicating in high numbers and leading to placentitis and abortion, an ability also exerted by the B. melitensis live-attenuated Rev1 strain, the only vaccine available for ovine brucellosis. It is broadly accepted that this tropism is mediated, at least in part, by the presence of certain preferred nutrients in the placenta, particularly erythritol, a polyol that is ultimately incorporated into the Brucella central carbon metabolism via two reactions dependent on transaldolase (Tal) or fructose-bisphosphate aldolase (Fba). In the light of these remarks, we propose that blocking the incorporation of erythritol into the central carbon metabolism of Rev1 by deleting the genes encoding Tal and Fba may impair the ability of the vaccine to proliferate massively in the placenta. Therefore, a Rev1?fba?tal double mutant was generated and confirmed to be unable to use erythritol. This mutant exhibited a reduced intracellular fitness both in BeWo trophoblasts and THP-1 macrophages. In the murine model, Rev1?fba?tal provided comparable protection to the Rev1 reference vaccine while inducing fewer adverse reproductive events in pregnant animals. Altogether, these results postulate the Rev1?fba?tal mutant as a reproductively safer Rev1-derived vaccine candidate to be studied in the natural host.This research was carried out in the frame of projects PID2023-146797OB-C31, PID2023-
