    A contribution to nutritional studies on Crocus sativus flowers and their value as food
    (Elsevier, 2013-08-02) Serrano Díaz, Jéssica; Sánchez, Ana M.; Martínez Tomé, Magdalena; Winterhalter, Peter; Alonso Díaz-Marta, Gonzalo L.; Tecnología de Alimentos, Nutrición y Bromatología
    About 68 kg of flowers are needed to produce 1 kg of saffron spice, while 63 kg of bio-residues composed of tepals, stamens and styles are generated. The proximate composition, minerals, dietary fiber (DF), sugars, anions and organic acids of flowers of saffron, their parts and bio-residues from saffron spice production have been analyzed. Whole flowers have high ash (7.39 mg/100 g), protein (10.07 mg/100 g) and available carbohydrates (61.2 mg/100 g), and are low in lipids (3.16 mg/100 g). Stamens are the flower parts with the highest contents of ash (11.43 mg/100 g), protein (24.05 mg/100 g), lipids (10.73 mg/100 g), total DF (32.2 mg/100 g) and insoluble DF (21.1 mg/100 g), and the lowest available carbohydrates (33.8 mg/100 g) and total sugars (4.3 mg/100 g). The insoluble/soluble DF ratios of floral bio-residues (1.2), stamens (1.9) and stigmas (1.3) are suitable as a balanced source of DF. These results could contribute to the using flowers of saffron as food, as well as the development of new food products from flowers of saffron and the management and exploitation of the bio-residues obtained in saffron spice production.

    Desarrollo de Pan de Masa Madre Funcional sin gluten con la adición del subproducto de la industria agroalimentaria de Opuntia ficus-indica tratado por pulsos eléctricos
    (2026) Muñoz Ros, María de los Ángeles; Nieto Martínez, Gema; Peñalver Miras, Rocío; Nieto Martínez, Gema; Sin departamento asociado; Facultades de la UMU::Facultad de Química
    Celiac disease (CD) is a chronic autoimmune disorder affecting about 1% of the population, characterized by adverse immune responses to gluten. The only effective therapy is a permanent gluten-free diet that shows numerous nutritional deficiencies. For all the above, the objective of developing a functional sourdough gluten-free bread formulation enriched with the by-product of the agro-food industry of Opuntia ficus-indica or purple prickly pear (HCM) is presented. For this, four formulations were developed in order to evaluate their effects: Control; P1, bread with dried HCM skin flour (H1); P2, bread with dried HCM skin encapsulated flour (H2); P3, bread with dried HCM skin flour pre-treated with PEF (H3); and, a Commercial formulation. In this way, a nutritional characterization was carried out by determining moisture, proteins, fat, ash, carbohydrates, energy value and fiber; the pH, total titratable acidity (ATT), color and mineral composition of the breads and by-products of HCM were analyzed; the microstructure (SEM) and starch, lactic acid and acetic content of the breads were evaluated; water and oil retention capacities (WHC and OHC) and solubility of the ingredients in the formulations were determined; and, the antioxidant capacity (FRAP, DPPH, ABTS) and total phenolic content (TFC) (Folin-Ciocalteau method) of the formulations, skin flours of HCM and other selected ingredients were evaluated. The most outstanding results were, in terms of nutritional properties, an increase of 10,48% of ash, 10,32% of FDI, 352,63% of FDS y 35,96% of FDT, as well as a decrease of 6,19% of moisture, 2,54% of carbohydrates and 7,77% of energy value when adding HCM skin flour treated with PEF prior to drying (H3). Significant increases in the content of Ca2+ and K+ were also highlighted due to the addition of H3 to the bread formulation, as well as the notable improvement in antioxidant capacity and TPC in P2 bread with encapsulated dried HCM skin flour. In conclusion, the incorporation of this by-product and the treatments to which it was subjected allowed the nutritional improvement of gluten-free breads, especially in terms of antioxidant capacity, TPC and mineral content.

    Los exvotos en textos hispánicos de los siglos XIII al XVI : piedras y minerales como objetos de un sensorium devocional.
    (Sociedad Española de Estudios Medievales., 2023) Rodríguez, Gerardo Fabián; Miranda, Lidia Raquel
    The paper analyses the role that mineral objects and stones, described in medieval sources as votive offerings, play in the construction of a significant world. To do this, it evaluates the relationship that they establish, in the miraculous context, with the devotees, which configures them in a rank of entity equivalent or superior to that of the properly human due to the purpose and the way in which each actant uses them, and especially by the sensory aspect that defines such contacts allowing us to recognize specific characteristics of a sensorium that we qualify as devotional.

    Influence of Maternal Supplementation with Vitamins, Minerals, and (or) Protein/Energy on Placental Development and Angiogenic Factors in Beef Heifers during Pregnancy
    (MDPI, 2024-03-02) Davila Ruiz, Bethania J; Dahlen, Carl R; McCarthy, Kacie L; Caton, Joel S; Hurlbert, Jennifer L; Baumgaertner, Friederike; Menezes, Ana Clara B; Diniz, Wellison JS; Underdahl, Sarah R; Kirsch, James D; Sedivec, Kevin K; Bochantin, Keri A; Borowicz, Pawel P; Cánovas Bernabé, Sebastián; Reynolds, Lawrence P; Fisiología
    Understanding placental vascularity is vital for ensuring the proper nourishment of the fetus and, therefore, a healthy offspring. We aimed to investigate the impact of vitamin and mineral supplementation and/or different rates of body weight gain on placental vascularity in beef heifers. To this end, in the first experiment, heifers were divided into groups that received vitamin and mineral supplementation or did not at least 72 days before breeding. At breeding, they were further divided into low or moderate-weight gain groups, resulting in four different treatments maintained until day 83 of pregnancy when tissue collection was performed. In the second experiment, another group of heifers received a basal diet or a diet with vitamin and mineral supplementation from breeding until parturition. We evaluated placental blood vessel density in both experiments and the placental expression of genes related to blood vessel growth in the first experiment. Results showed that supplementation and the rate of body weight gain during early pregnancy did not significantly affect placental vascularity or the expression of angiogenic factors. On the other hand, placental vascularity measured at parturition was increased in the fetal placenta of the supplemented group. These findings suggest that supplementation with vitamins and minerals throughout all gestation may impact placental function at a later stage of pregnancy.
