Instant infant cereals reconstituted with infant formula are the first complementary food for most Spanish infants. The main aim is to provide information on sugars in the formulation of infant cereals. Product information was collected from department stores, supermarkets, and pharmacies and completed with data from brand websites. A portion of the samples was selected for total sugars determination using the HPLC and Luff-Schoorl methods. The information regarding a total of 120 milk-free instant infant cereals marketed in Spain from 12 companies was summarized. The mean of total sugars was 23 +/- 9 g/100 g (25-42%), providing 24% of the calories. Most of porridges are prepared with partially hydrolyzed flours providing free sugars (glucose and maltose). The most commonly added sugar is sucrose. A total of 43.3% of products contain added sucrose, and 16.7% contain fruits. Infant cereals analyzed with added sugars can have a sugar content similar to that found in products without added sugars. Consistent differences were found in sugars content between assayed methods and this label information. Although the European legislation of infant cereals establishes values for added sugars, the labeling reflects the content of total sugars, but not that of added sugars.

The tiger nut, compared to other tubers, has higher carbohydrate content, which mostly remain in the byproduct after the production of tiger nut milk ("Horchata"). The aim of this study is the optimization of a hydrolysis pre-treatment in tiger nut byproduct to obtain reducing sugars, objective framed in the European SUSPUFA (Sustainable production of health-promoting n-3 LC-PUFA using agro-food industry by-products through microalgae) Project. Two experimental 4-factor Box–Behnken designs (acid concentration (N), temperature (◦C), time (min) and ratio acid/sample) were carried out with 27 experiments to optimize chemical hydrolysis conditions with H2SO4 and H3PO4 in duplicate. The sugars were determined by the Schoorl method and the extracts obtained by the optimal conditions were analyzed by high-performance liquid chromatography (HPLC). Protected designation of origin (PDO) and non-protected designation of origin (n-PDO) tiger nut byproducts were characterized by physicochemical methods. The validity of the experimental designs was confirmed by ANOVA. The optimum sugar values were obtained with H2SO4 2 N at 85 ◦C, 60 min and ratio 60 and H3PO4 21 N at 90 ◦C, 60 min and ratio 60. Glucose and xylose were the sugars detected in the hydrolyzed samples. In conclusion, almost 50% of the total carbohydrates present in the tiger nut byproduct were hydrolyzed to reducing sugars. ; This study is part of ERA-Net SUSFOOD2 project SUSPUFA, ID 145, funding provided by Spanish Ministry of Science, Education and Universities/ Spanish State Research Agency (PCI2018-093178) and co-funding by the European Union's Horizon 2020 research and innovation program.

The use of essential oils (EOs) in the food industry is a popular research topic, as they have antioxidant and antimicrobial activity and could be used as ingredients directly in food or as bioactive component in food coating and food packaging. Thus, the study of their antioxidant and antimicrobial activity is a crucial step to evaluate their use in food packaging/coating. In this work, we evaluate the antioxidant and antimicrobial activities of 13 EOs from herbs, spices, fruits, and vegetables. Briefly, the EOs from aromatic herbs and spices showed the highest antioxidant and antimicrobial activity. Fennel essential oil reported the lowest antioxidant activity, however it showed very good antimicrobial activity against Botrytis cinerea, one of the post-harvest pathogen microorganisms in fruits and vegetables. ; In the field of food preservation, encapsulated Essential Oils (EOs) could be the best non-toxic and eco-friendly tool for food preservative applications substituting the chemicals ones that have several disadvantages for the environment and health. Thirteen commercial EOs from plants, fruits, and vegetables were characterized by GC-MS. The antioxidant activity was measured by DPPH and ABTS techniques. Antimicrobial activity was assessed by agar well-diffusion method and the Minimum Inhibitory Concentration (MIC) by agar dilution method against six bacteria, Candida albicans, and Botrytis cinerea. All the EOs tested have demonstrated antioxidant activity in the range of IC50 0.01–105.32 mg/mL. Between them, cinnamon EOs were the best, followed by oregano and thyme EOs. Fennel EO showed the lowest radical scavenging. MIC values ranged from 0.14 to 9 mg/mL. C. cassia, thyme, and oregano EOs were the most effective against the bacterial species tested, and the yeast C. albicans. On the contrary, citric fruit EOs showed low or no inhibition against most bacterial strains. The percentages of inhibition of mycelia growth of B. cinerea ranged from 3.4 to 98.5%. Thyme, oregano, mint, and fennel EOs showed the highest inhibition. ; European Union's Horizon 2020 -No 817936

Una vez licenciado, el farmacéutico puede optar por un elevado número de salidas profesionales, tanto en el sector público al servicio de los diferentes cuerpos y administraciones, como en el sector privado. Los perfiles profesionales más frecuentes del farmacéutico pueden englobarse en 4 modalidades: Oficina de Farmacia (Farmacia Comunitaria), Farmacia Hospitalaria, Distribución e Industria Farmacéutica o Análisis y Salud Pública. A nivel de oficina de farmacia, el farmacéutico, junto a la dispensación de medicamentos, ejerce un destacado papel como asesor y consejero de salud. Las estadísticas desvelan que una de cada cuatro personas que entran en una farmacia no adquiere medicamentos, sino que sólo pide un consejo sanitario, incluyendo asesoría sobre dietas, alimentación y nutrición. Además, la aparición en los últimos años de complementos alimenticios, de venta en farmacia, hace que el farmacéutico deba formarse y comportarse como profesional en lo que respecta a temas de nutrición. Otra salida profesional, como la inspección Farmacéutica, incluye la supervisión de agua y alimentos no animales, por lo que el farmacéutico debe tener un amplio conocimiento sobre la legislación, sanidad y análisis de alimentos. Por otro lado, la industria farmacéutica incluye una amplia variedad de salidas profesionales, incluyéndose dirección técnica, control de calidad y de fabricación, gestión comercial, documentación científica o análisis. La industria agroalimentaria ha experimentado importantes cambios en las últimas décadas, exigiendo profesionales en la materia, como dietistas o analistas bromatológicos, dentro de un equipo multidisciplinar. En este sentido, el farmacéutico, a través del nuevo grado en Farmacia, debe adquirir una base sólida en el campo de la nutrición y bromatología. Así, las competencias recogidas en la Orden CIN/2137/2008 ponen de manifiesto la importancia de la formación del futuro farmacéutico en el ámbito de la alimentación. ; Once graduated, the pharmacist can choose a high number of professional skills, both in public and private sectors. The most frequent professional skills of the pharmacist can be included in 4 different fields: Pharmacy Office (Communitary Pharmacy), Hospital Pharmacy, Distribution and Pharmaceutical Industry or Analysis and Public Health. At the pharmacy office level, the pharmacist, along with the medicines dispensation, exercises an out-standing role as health adviser. The statistics reveal that 25% of the pharmacy customers do not acquire medicines, but they only ask for a sanitary advice, including nutrition and dietetic consultations. Moreover, in the last years nutritive supplements have been included within the pharmaceutical sales. Thus, the pharmacist should be formed about nutritional topics. Another professional skill, like the pharmaceutical inspection, includes drinkable water and non-animal foodstuffs analyses. Then, the pharmacist should have a wide knowledge on legislation, health and food analysis. On the other hand, the pharmaceutical industry includes a wide variety of professional skills, including technical direction, quality control, commercial management, scientific documentation or analysis. Finally, the agro-alimentary industry has experienced important changes in the last decades, demanding professionals in the matter, like dietitians or food analysts. In this sense, the pharmacist, across the new degree in Pharmacy, must acquire a solid base in the nutrition and bromatology field. Therefore, the competences gathered in the Disposition CIN / 2137/2008 reveals the importance of the formation of the future pharmacist in the nutrition area.
