Plan Director de la Vega Baja. Mirando al futuro desde el pasado.

El Plan Director de la Vega Baja fue aprobado en Toledo el 9 de febrero de 2011. Su objetivo básico es fijar las líneas generales que guiarán la actuación para recuperar y poner en valor este ámbito. El presente libro es el resultado de las aportaciones de expertos de distintas disciplinas que participaron en el proceso de redacción del Plan, sus diferentes formas de aproximarse a este espacio constituyen la primera parte del libro. La segunda parte es el documento aprobado del Plan Director (memoria y planos). En el proceso de definición de la propuesta ha resultado fundamental el estudio del pasado y de la evolución de la Vega Baja, un espacio significado por sus características geográficas y medio ambientales, y por las fuertes connotaciones históricas y culturales que se reflejan en el diálogo paisajístico de la Vega y el Casco Antiguo de Toledo. En el argumento de la recuperación de la Vega Baja se suman los aspectos físicos y medioambientales, las necesidades de los ciudadanos del entorno, y la recuperación cultural y simbólica de la Vega Baja.

Graph based study of allergen cross-reactivity of plant lipid transfer proteins (LTPs) using microarray in a multicenter study.

The study of cross-reactivity in allergy is key to both understanding. the allergic response of many patients and providing them with a rational treatment In the present study, protein microarrays and a co-sensitization graph approach were used in conjunction with an allergen microarray immunoassay. This enabled us to include a wide number of proteins and a large number of patients, and to study sensitization profiles among members of the LTP family. Fourteen LTPs from the most frequent plant food-induced allergies in the geographical area studied were printed into a microarray specifically designed for this research. 212 patients with fruit allergy and 117 food-tolerant pollen allergic subjects were recruited from seven regions of Spain with different pollen profiles, and their sera were tested with allergen microarray. This approach has proven itself to be a good tool to study cross-reactivity between members of LTP family, and could become a useful strategy to analyze other families of allergens.

The involvement of thaumatin-like proteins in plant food cross-reactivity: a multicenter study using a specific protein microarray.

Cross-reactivity of plant foods is an important phenomenon in allergy, with geographical variations with respect to the number and prevalence of the allergens involved in this process, whose complexity requires detailed studies. We have addressed the role of thaumatin-like proteins (TLPs) in cross-reactivity between fruit and pollen allergies. A representative panel of 16 purified TLPs was printed onto an allergen microarray. The proteins selected belonged to the sources most frequently associated with peach allergy in representative regions of Spain. Sera from two groups of well characterized patients, one with allergy to Rosaceae fruit (FAG) and another against pollens but tolerant to food-plant allergens (PAG), were obtained from seven geographical areas with different environmental pollen profiles. Cross-reactivity between members of this family was demonstrated by inhibition assays. Only 6 out of 16 purified TLPs showed noticeable allergenic activity in the studied populations. Pru p 2.0201, the peach TLP (41%), chestnut TLP (24%) and plane pollen TLP (22%) proved to be allergens of probable relevance to fruit allergy, being mainly associated with pollen sensitization, and strongly linked to specific geographical areas such as Barcelona, Bilbao, the Canary Islands and Madrid. The patients exhibited mayor que50% positive response to Pru p 2.0201 and to chestnut TLP in these specific areas. Therefore, their recognition patterns were associated with the geographical area, suggesting a role for pollen in the sensitization of these allergens. Finally, the co-sensitizations of patients considering pairs of TLP allergens were analyzed by using the co-sensitization graph associated with an allergen microarray immunoassay. Our data indicate that TLPs are significant allergens in plant food allergy and should be considered when diagnosing and treating pollen-food allergy.

La confianza como instrumento de análisis en la cadena de valor alimentaria

El nuevo escenario al que se enfrenta el sector agroalimentario, caracterizado por una mayor complejidad y tecnificación del mismo, hace que la confianza sea un activo importante para su rendimiento y buen funcionamiento. El objetivo de la siguiente investigación es mejorar el sector agroalimentario mediante la confianza. Para ello, se pretende conocer qué elementos se usan para que la confianza aparezca en el sector agroalimentario, tomando el sector desde una perspectiva holística. Para lograr este objetivo se han seguido varias etapas. En primer lugar, se analizaron los conceptos confianza y sector agroalimentario para, posteriormente, mostrar qué aspectos de la confianza habían sido objeto de investigación en dicho sector. Tomando algunas premisas basadas en la economía neoinstitucional se definieron una serie de elementos en los que descansa la confianza. Tomando los estudios de caso como herramienta de metodología cualitativa para validar esos componentes de la confianza se concluye con una definición o marco teórico aplicable a la confianza en el sector agroalimentario. Los componentes más importantes son las personas, las instituciones y los procesos que entre ellos se producen dando lugar a las relaciones. Estas relaciones de confianza se ven condicionadas por el comportamiento y conducta de estos agentes, la satisfacción percibida, la dependencia de otros agentes y el riesgo. Además, para regular y hacer visible estos elementos, la confianza se sirve de instrumentos como los precios, los contratos y los sistemas de calidad, así como de la especificación del producto que es intercambiado Debido a su carácter cualitativo y exploratorio la investigación deja espacio para futuras investigaciones en las que se puedan medir y cuantificar la importancia de estos los elementos. Agrifood sector faces a new scenario featured by a great complexity. The aim of this work is the improvement of agricultural and food sector analyzing trust as a key asset. This work tries to answer on what items, tools or concepts rely trust in agricultural and food sector taking agrifood sector from a holistic perspective. To achieve this goal, qualitative methodology based on case studies analysis is carried out following several stages. First, a deep literature review about the food and agricultural environment and the concept of trust is analyzed. Secondly, a state of the art about how trust in food an agricultural sector has been researched is presented. Next, a scenario which takes some premises derived from neo-institutional economics is depicted. This scenario helps to define a framework for understanding how trust emerges in agrifood sector. Finally using the case studies as a tool to validate the framework the definition for trust is developed as result. Trust in food sector relays on persons, institutions and processes and the resulting relationships between them. Trust relationships are conditioned by the behavior and conduct of these agents, their perceived satisfaction, the dependence on other agents and risk. To regulate and make visible these elements, trust uses tools like prices, contracts and quality systems. The research presents some limitations due its qualitative nature. Further research lines are opened in order to evaluate and measure the relevance of different components of the framework.

Comparative characterization of dietary fibre-Enriched Frozen/thawed mashed potatoes

The potential use of commercial fibres (pea fibre, inulin, and their blends), as fibre-enriching agents in frozen/thawed mashed potatoes was reported. Pea fibre and inulin supplementations conferred hardness and softness to the product, respectively. Differences were attributed to the relationship of the fibre with the potato starch matrix. The association of pea fibre at low concentration (<15 g/kg mashed potatoes) and inulin at high concentration (>45 g/kg) is strongly encouraged to fortify the diet without promoting negative effects on textural and rheological properties of frozen/thawed mashed potatoes or colour and overall acceptability of the resulting products.

Rheological behaviour and functionality of inulin-extra virgin olive oil-based mashed potatoes

Developing products having a high nutritional value and good storage stability during freezing is a challenge. Inulin (I) and extra virgin olive oil (EVOO) have interesting functional properties. The e?ect of the addition of I and EVOO blends at di?erent I:EVOO ratios (0:0, 0:60, 15:45, 30:30, 45:15, 60:0, 30:45 and 45:30) on the rheological, physical, sensory and structural properties of fresh and frozen ? thawed mashed potatoes formulated without and with added cryoprotectants was analysed and compared. Addition of I and EVOO (either alone or blended) reduced apparent viscosity and pseudoplasticity producing softer systems, indicating that both ingredients behave as soft ?llers. Samples with added I at the higher concentrations )1 (?45 g kg ) showed lower ?ow index and consistency, which is related to formation of smaller I particles; microphotographs indicated that gelling properties of I depended mostly upon processing. Frozen ? thawed samples were judged more acceptable and creamier than their fresh counterparts.

Sensory and texture properties of mashed potato incorporated wigh inulin and olive oil blends

The effect of adding different ratios of inulin and extra virgin olive oil blends, formulated without (MPA) and with cryoprotectants (MPB), on texture properties of fresh mashed potatoes and frozen/thawed mashed potatoes was studied. Inulin and extra virgin olive oil behaved like soft ?llers, but inulin was associated with increased?brousness and extra virgin olive oil with increased creaminess. In the total dataset and frozen mashed potatoes, frozen/thawed mashed potatoes, and MPA subgroups, component 1 was a contrast between mechanical and surface textural attributes, whereas in MPB samples component 1 was determined by geometrical attributes. Addition of inulin at 30 g/kg and extra virgin olive oil at 45 g/kg is recommended.

A rheological characterization of mashed potatoes enriched with soy protein isolate

The effect of the addition of soy protein isolate (SPI) (0, 15, 30, 45 and 60 g kg ) on viscoelastic properties, large deformation measurements and microstructure of fresh (FM) and frozen/thawed (F/TM) mashed potatoes was investigated. Rheological data showed weak gel behaviour for both FM and F/TM potatoes without and with added SPI together with a signi?cant decrease of system viscoelasticity (G and G ) with increasing SPI volume fraction, primarily attributed to the no interaction between the amylose/amylopectine matrix and the dispersed SPI particles or aggregates as revealed by scanning electron microscopy (SEM). Micrographs also showed that SPI formed white coarse aggregates. A freeze/thaw cycle produced a more signi?cant decrease in viscoelastic functions, due to superior aggregation of denatured SPI and reduced water activity. In F/TM samples, high correlations between small and large deformation measurements were found. Results may be useful for technological applications in SPI-enriched.
