- ItemOpen AccessLa filosofía sintética: ¿Qué es y por qué todo filósofo dedicado a la investigación debería adoptarla?(Universidad Complutense de Madrid, 2024) Teixidó, Óscar; Carcacía Campos, IsaacUna respuesta al debate metafilosófico sobre si hay o no unos criterios regulativos en filosofía cómo área de investigación lo ofrece la denominada filosofía sintética. Dentro de esta posición se propone una forma de abordar toda la filosofía y teorizar en base a diferentes criterios propuestos, que suelen ser generalmente: la claridad semántica, la coherencia interna, la coherencia externa con las ciencias y la fecundidad teórica con otros campos de estudio. Estos criterios de corte naturalista a su vez se ofrecen como debatibles y ampliables a otros criterios. Se razonará la necesidad de demarcar la filosofía, y, poniendo el foco en su metodología, se argumentarán los previos criterios con tal de fomentar la filosofía sintética como marco general de trabajo filosófico riguroso. Esto excluye de la disciplina tanto aquello que no sea filosófico como aquello que intente emular la filosofía sin serlo en verdad, la pseudofilosofía.
- ItemOpen Access¿Cómo se pueden prevenir o controlar las micotoxinas?(Grupo Asis, 2021) Ramos Girona, Antonio J.; Marín Sillué, SòniaEl text tracta sobre les estratègies per prevenir i controlar les micotoxines en la cadena alimentària. Destaca la importància de les bones pràctiques agrícoles i de postcollita, així com l’ús de fungicides i sistemes de bio control. També s’aborden mètodes com l’adsorció en el tracte digestiu animal i la biotransformació per reduir la toxicitat. S’hi subratlla la necessitat d’adaptar les mesures a les condicions climàtiques i agronòmiques locals. Finalment, es considera essencial la monitoratge i gestió integral per garantir la seguretat alimentària.
- ItemOpen AccessThermal stability of deoxynivalenol, zearalenone, and their modified forms during baking in oat biscuits(Elsevier, 2025) Teixido-Orries, Irene; Molino Gahete, Francisco; Aragonés Millán, Ángel; Ramos Girona, Antonio J.; Marín Sillué, SòniaThe present study aimed to investigate the effects of the baking process on some Fusarium mycotoxins (deoxynivalenol (DON), zearalenone (ZEN), T-2 and HT-2 toxins) and their modified forms (deoxynivalenol-3-glucoside (DON-3G), 15-acetyldeoxynivalenol (15-ADON), 3-acetyldeoxynivalenol (3-ADON), deepoxy-deoxynivalenol (DOM-1), α-zearalenol (α-ZEL), and β-zearalenol (β-ZEL)) in oat biscuits. Their content was analysed using HPLC-DAD and UHPLC-MS/MS to evaluate the impact of temperature, time and initial mycotoxin concentration. Also, metabolite screening (sulphated ZEN metabolites, isoDON and norDONs) was performed to provide new insights into the baking effect on mycotoxins. Results indicated that mycotoxin reduction depended significantly on baking temperature and duration. ZEN exhibited higher thermostability than DON-3G, and DON-3G was more thermostable than DON. Under harsh conditions, 15-ADON decreased while DOM-1 increased. isoDON and norDONs emerged during baking. Initial baking phases showed increased levels of ZEN, α-zearalenol-14-S (α-ZEL-14-S) and β-zearalenol-14-S (β-ZEL-14-S) due to the release of hidden mycotoxins, raising safety concerns. T-2 and HT-2 toxins were not found in any oat-based product. The final edible biscuits for each temperature exhibited similar DON and DON-3G concentrations, with higher ZEN levels than initially. Degradation kinetic analysis revealed zero-order kinetics for DON and DON-3G and first-order kinetics for ZEN, offering a predictive tool for mycotoxin levels in biscuits.
- ItemOpen AccessIncorporation of β-carotene O/W emulsions into dairy foods: Impact of the colloidal stability during in vitro digestion on the lipolysis and bioaccessibility(Elsevier, 2025) Molet Rodríguez, Anna; Martín Belloso, Olga; Salvia Trujillo, LauraO/W emulsions have been proposed as delivery systems of lipophilic bioactive compounds into water-based foods. This work aimed to study the impact of the food matrix on the colloidal stability of β-carotene-loaded O/W emulsion incorporated into dairy products (milk and yogurt) before and during in vitro gastrointestinal (GI) digestion. The relationship between colloidal stability, lipolysis and β-carotene bioaccessibility was also evaluated. The colloidal stability of the O/W emulsion was maintained once it was incorporated into dairy products and during GI conditions, without a significant impact of the food matrix. However, lipolysis, as FFA release, was faster and higher once the O/W emulsion (64.58 ± 2.76 %) was co-digested with dairy products (>81 %). Nevertheless, they presented non-significant differences in β-carotene bioaccessibility (38–44 %), thus dairy matrices would limit mixed micelles formation or β-carotene micellarization. This work provides valuable insight for designing dairy products fortified with bioactive compounds by using emulsions as delivery systems.
- ItemOpen AccessFinger-prick blood sampling using volumetric absorptive microsampling (VAMS) method for monitoring the main (poly)phenolic metabolites in human blood after barley biscuit intake(Elsevier, 2025-02-21) Cortijo-Alfonso, Maria Engracia; Yuste, Silvia; Piñol Felis, Carme; Romero Fabregat, Mª Paz; Macià i Puig, Ma Alba; Rubió Piqué, LauraA novel method based on volumetric absorptive micro-sampling (VAMS) combined with UPLC-MS/MS was developed and validated to determine the principal (poly)phenolic metabolites in human blood following the consumption of 140 g of purple whole-grain barley (WGB) biscuits. Finger-prick blood samples were collected from 11 healthy volunteers at multiple time points up to 48 h post-ingestion. To extract (poly)phenolic metabolites efficiently, various extraction parameters were optimized. Then, the method was successfully applied and five colonic (poly)phenolic metabolites from the main (poly)phenolic families from barley were detected: benzene-1,2-diol-O-sulphate, 3-(4 ′-hydroxy-3 ′-methoxy)propanoic acid and its sulphated form, 5 ′-(3 ′ ,4-dihydroxyphenyl)-γ-valerolactone-O-sulphate, and methyl luteolin-O-glucuronide. Maximum absorption occurred at 12 h for most metabolites, while luteolin-O-glucuronide showed two distinct peaks at 2 and 6 h, indicating its dual-phase absorption. Comparison with venous plasma samples collected during the 0–6 h period showed no significant differences (p > 0.05), validating the statistical reliability of VAMS as an alternative to venipuncture. Thus, VAMS emerges as a less invasive and statistically robust means for analyzing the pharmacokinetic profile of (poly)phenols, particularly those arising from colonic metabolism.
