    Nutritional and Phytochemical Composition of MediterraneanWild Vegetables after Culinary Treatment
    (MDPI, 2020-11-28) García Herrera, Patricia; Morales Gómez, Patricia; Montaña Cámara, Montaña; Fernández Ruiz, Virginia; Tardío, Javier; Sánchez Mata, María Cortes
    Studies are scarce on the nutritional and phytochemical composition of wild edible Mediterranean plants after culinary processing. This work provides the nutritional composition after culinary treatment (including dietary fiber and mineral composition) and bioactive compounds (folates, vitamin C and organic acids) of wild Rumex pulcher L., Silene vulgaris (Moench) Garcke. leaves, and wild Asparagus acutifolius L., Bryonia dioica Jacq., Humulus lupulus L., Tamus communis L. young shoots. Shoots better preserved their nutrients than leaves, due to their different tissue structure. Fresh and cooked wild greens present high dietary fiber values, and remained at remarkable levels after boiling. Na, K, Mg and Zn were lost in about 50% due to culinary processing, while Ca, Cu, Fe and Mn were more stable. Boiled leaves of S. vulgaris remained as a good Mn source. A portion of 100 g of most of the cooked analyzed species could cover a relevant percentage of the daily requirement of folates (R. pulcher and A. acutifolius providing more than 80%) and vitamin C (T. communis and A. acutifolius providing more than 35%).

    Durum and Bread Wheat Flours. Preliminary Mineral Characterization and Its Potential Health Claims
    (MDPI, 2021-05-08) Ciudad Mulero, María; Matallana González, María Cruz; Callejo, Mª Jesús; Carrillo, José M.; Morales Gómez, Patricia; Fernández Ruiz, Virginia
    Wheat is one of the most important cereals in terms of its role in the human diet. The distribution of the nutrients in wheat grains depends largely on their morphology, the bran fraction being the richest in minerals, thus developing important functions related to human health. The main purpose of this study was to point out the potential nutritional and health claims related to the mineral composition based on the current European legislation in order to valorize the interesting wheat varieties traditionally consumed in Spain. The mineral composition (microelements: Fe, Cu, Mn, and Zn; and macrolements: Ca, Mg, Na, and K) were evaluated in different milling fractions (white flour, whole grain flour, and bran fraction) of 4 wheat varieties of durum (Triticum turgidum ssp. durum Linnaeus) and bread (Triticum aestivum Linnaeus) wheat. As expected, the mineral concentration was higher in the case of bran and whole grain flour, K and Mg being the principal minerals found. A difference between wheat genotype and harvesting year have been found. Moreover, regarding these preliminary results, some samples analysed in the present study met the conditions of use of different approved health claims that could support the possibility to consider wheat flours, especially whole grain flour and bran fraction as functional foods, but some did not.

    Extrusion Cooking Effect on Carbohydrate Fraction in Novel Gluten-Free Flours Based on Chickpea and Rice
    (MPDI, 2022-02-08) Ciudad Mulero, María; Niño Vega, Erika; García Herrera, Patricia; Pedrosa, Mercedes M.; Arribas, Claudia; Berrios, José De J.; Cámara Hurtado, Montaña; Fernández Ruiz, Virginia; Morales Gómez, Patricia
    Extrusion cooking allows the development of value-added products from pulses, such as gluten-free snacks with added functional properties. The main objective of this study was to evaluate the changes induced by the extrusion process on the carbohydrate fraction (total carbohydrates, soluble sugars and oligosaccharides, dietary fiber, and arabinoxylans) of novel flour formulations based on chickpeas and rice enriched with different dietary fiber sources. Moreover, the influence of the addition of fiber-rich ingredients, such as Fibersol® and passion fruit, on the analyzed compounds was also evaluated. Sucrose was the main soluble sugar found in analyzed formulations, and raffinose was the prevalent oligosaccharide, followed by stachyose. The content of total α-galactosides tended to be higher after extrusion cooking. As a consequence of the extrusion treatment, the content of total and soluble dietary fiber was statistically increased in most of the analyzed samples. In general, no significant changes were observed in total arabinoxylan content as a consequence of the extrusion process, while the content of water-soluble arabinoxylans was significantly increased in extruded formulations. It was observed that the content of total available carbohydrates, stachyose, and water-soluble arabinoxylans were significantly influenced by the addition of passion fruit, Fibersol®, and both. The incorporation of these ingredients in gluten-free formulations based on chickpeas and rice allows one to obtain suitable functional formulations for the development of innovative, gluten-free, extruded snack-type products, which could be an interesting alternative for people with celiac disease.

    Potential Health Claims of Durum and Bread Wheat Flours as Functional Ingredients
    (MDPI, 2020-02-17) Ciudad Mulero, María; Barros, Lillian; Fernandes, Ângela; Ferreira, Isabel C.F.R.; Callejo, Mª Jesús; Matallana González, María Cruz; Fernández Ruiz, Virginia; Morales Gómez, Patricia; Carrillo Becerril, José María
    Wheat is an important cereal with a key role in human nutrition. In this study, dietary fiber (DF) and arabinoxylans of different durum (Triticum turgidum ssp. Durum L.) and bread (Triticum aestivum L.) wheat flours were analyzed in order to point out their potential nutritional and health claims allege according to the current European regulation (Regulation (EU) No 432/2012). Moreover, other bioactive compounds (phenolics and tocopherols) were quantified as a first approach to their phytochemical composition in the analyzed wheat varieties. DF was analyzed following AOAC enzymatic-gravimetric methods; arabinoxylans and total phenols were quantified by colorimetric methods; tocopherols were determined by HPLC; antioxidant activity was evaluated using three different in vitro assays. Insoluble DF was the prevailing fraction in all analyzed samples. Water extractable arabinoxylans were higher in durum wheat flours. Whole flours contained higher total phenolics compounds. Alpha-tocopherol was the major isoform. Whole flours showed higher antioxidant properties. According to the obtained results, it is possible to allege all approved health claims referred to wheat, since all analyzed samples, especially whole flour and bran fraction, showed potential health benefits, as functional ingredients or functional foods, related with their phytochemical composition.

    A Review of the Role of Micronutrients and Bioactive Compounds on Immune System Supporting to Fight against the COVID-19 Disease
    (MDPI, 2021-05-14) Cámara Hurtado, María de la Montaña; Sánchez Mata, María de Cortes; Fernández Ruiz, Virginia; Cebadera Miranda, María Elena; Domínguez Díaz, Laura
    Micronutrients are critical for an adequate function of the immune system and play a vital role in promoting health and nutritional well-being. The present work is aimed at reviewing (1) the role of micronutrients in helping the immune system to fight against the COVID-19 disease through the diet with food or food supplements and (2) the potential use of food health claims regarding immune function according to the European Food Safety Authority (EFSA) requirements. Till date, there are some health claims authorized by the European Commission that refer to the role of certain essential nutrients (vitamins B6 , B9 , B12, A, D, C, and Cu, Fe, Se) to contribute to the proper functioning of the immune system. Vitamins D, C, Zn, and Se, have been thoroughly studied as a strategy to improve the immune system to fight against COVID-19 disease. From all the micronutrients, Vitamin D is the one with more scientific evidence suggesting positive effects against COVID-19 disease as it is linked to a reduction of infection rates, as well as an improved outcomes in patients. To validate scientific evidence, different clinical trials are ongoing currently, with promising preliminary results although inconclusive yet.
