Nowadays, there are few options of low or no added sugar drinks offering health benefits and oriented to consumers with a special health condition, such as overweight and obesity. The objective of this work was to develop and characterize a low-calorie antioxidant beverage made from aqueous extracts of medicinal plants (Melissa and lemon verbena), flowers (chamomile and bougainvillea), and fruits (guava, pineapple, strawberry, orange, and tangerine) as an alternative for people with overweight and obesity. Four formulations were developed from medicinal plants, flowers, and fruits. For this, a solid-liquid conventional extraction was carried out (at 90 °C during 5 min) followed by a cold shock in ice. The developed beverages were characterized in a microbiological and physicochemical way according to official analysis methods. The sensory evaluation was carried out through liking and buying intention tests. The population under study was integrated by 400 adults divided into two groups (with and without overweight or obesity). The beverages developed were low-calorie (≤40 kcal per portion), very low in sodium (1.6 g GAE portion), and with an attractive color. The results indicate that these beverages could be an alternative to the consumption of common industrialized drinks conferring additional benefits for the prevention of chronic diseases.

The objective of this paper is to compare conventional, ultrasound, microwave, and French press methods for the extraction of antioxidant compounds from Decatropis bicolor in an aqueous medium. This plant is widely used in Mexican traditional medicine for breast cancer treatment. Despite that, there are few studies on D. bicolor. Two response surface designs were applied to establish the best conditions of the liberation of antioxidants from D. bicolor, which were determined by DPPH• and Ferric Reducing Antioxidant Power (FRAP) techniques. The total phenolic content was evaluated by the Folin-Ciocalteu method. The results showed that D. bicolor is a source of antioxidants (669–2128 mg ET/100 g and 553–1920 mg EFe2+/100 g, respectively) and phenolic compounds (2232–9929 mg EGA/100 g). Among the physical factors that were analyzed, the temperature was the determinant factor to liberate the compounds of interest by using low concentrations of the sample and short times of extraction. The French press was the most efficient method, obtaining values of antioxidant activity and phenolic compounds even higher than those reported by using extraction methods with solvents such as methanol.

Las pruebas triangulares son de tipo discriminativas y se utilizan diferencias organolépticas entre muestras o para la selección de un panel de catadores. El objetivo de este trabajo fue aplicar una prueba triangular para determinar si existen diferencias organolépticas entre muestras de dos productos de naturaleza semejante. En esta prueba se evaluaron dos muestras de yogur de marcas comerciales, las muestras se colocaron en vasos de 50 mL codificados con números aleatorios. Se presentaron tres muestras simultáneamente, dos de ellas son idénticas y una diferente. Se les pidió que evaluaran las muestras de izquierda a derecha y los resultados se recolectaron en la ficha de cata. Los resultados mostraron que el 79% de los panelistas logaron reconocer la muestra diferente, siendo el sabor, el atributo que marcó la diferencia, lo cual puede deberse a las materias primas y el proceso de elaboración que cada empresa sigue. Dentro de las pruebas discriminativas, la prueba triangular ayuda a establecer diferencias en algún atributo sensorial en muestras de la misma naturaleza.

Ginger rhizome is widely used in culinary preparations and in traditional medicine. Its benefits are associated with its antioxidant properties related to phenolics and terpenoids compounds, which use to be thermolabile. Ultrasound-assisted extraction has been useful for enhancing the release of thermosensitive compounds present in vegetable tissues. Therefore, the aim of this study was to evaluate the influence of ultrasound-assisted extraction on the release of antioxidants from ginger in aqueous media as well as their in vitro bioaccessibility. Central composite rotatable design was applied to obtain the optimal conditions for the extraction; the variables studied were amplitude (80–90%) and temperature (30–50 °C). Total phenolic content, antioxidant capacity (DPPH•, ABTS•+ and FRAP), and in vitro bioaccessibility were determined. Amplitude was the main parameter influencing the extraction of antioxidants. The ginger aqueous extracts showed a bioaccessibility of around 30%. The release of antioxidant compounds from ginger by ultrasound-assisted extraction avoids the use of high temperatures and solvents commonly used in conventional extraction methods.

The health benefits attributed to probiotics generate interest in the search of competent strains adapted to several ecological niches, especially those related to traditional beverages and foods of each country. Pineapple tepache, a traditional Mexican fermented beverage, was used for the isolation of lactic acid bacteria with probiotic potential, one of which withstood the in vitro tests. The isolated strain AB-05, which exhibited the tested probiotic functional properties, was designated as Lactobacillus pentosus ABHEAU-05. The sequence was registered in GenBank under access code MK587617. This study is the first report of a lactic acid bacterium with in vitro digestion resistance isolated from pineapple tepache. The survival of L. pentosus ABHEAU-05 in a symbiotic medium was proven using fermented milk enriched with inulin. The in vitro digestion-resistant probiotic activity of lactobacilli was measured through analysis of pH and proteolysis. Results showed that L. pentosus grew properly in fermented milk; therefore, this microorganism could be used in the manufacture of this kind of products. The concentration of L. pentosus reached up to 8.5 log CFU/ml after 40 h of fermentation. In addition, the production of peptides and the decrease in pH indicated the vigorous and active metabolic state of the lactic acid bacterium tested. The activity and the concentration of this microorganism were maintained during refrigeration. The results of this research conclude that L. plantarum ABHEAU-05 is an in vitro digestion-resistant microorganism that can be used as a starter culture for the production of functional foods of dairy origin. Los beneficios a la salud atribuidos a los probióticos generan interés en la búsqueda de cepas competentes adaptadas a varios nichos ecológicos, especialmente los relacionados con bebidas y alimentos tradicionales de cada país. En este estudio, se aisló del tepache de piña, una bebida fermentada tradicional mexicana, una bacteria láctica resistente a la digestión in vitro. Entre 5 bacterias aisladas, una de ellas soportó las pruebas simuladas de digestión gastrointestinal. Se analizó la resistencia a sales biliares, a condiciones ácidas y al ataque enzimático con pepsina. La bacteria aislada, que exhibió las propiedades funcionales probióticas referidas, fue identificada como Lactobacillus pentosus y designada como L. pentosus ABHEAU-05. La secuencia fue depositada en GenBank (acceso MK587617). Se comprobó la supervivencia de L. pentosus ABHEAU-05 en una leche fermentada adicionada con inulina y su resistencia a la digestión in vitro mediante el análisis del pH y la proteólisis. Los resultados muestran que la leche fermentada es una matriz adecuada, donde L. pentosus ABHEAU-05 se desarrolla sin inconvenientes, alcanzando un título de 8,5 log ufc/ml después de 40 h de fermentación. Además, la producción de péptidos y el descenso del pH indicaron el estado metabólico vigoroso y activo del microorganismo probiótico. Se concluye que L. pentosus ABHEAU-05 es un microorganismo resistente a la digestión in vitro, que puede servir como cultivo iniciador para la producción de alimentos de origen lácteo. Este es el primer informe acerca del aislamiento de una bacteria ácido láctica resistente a la digestión in vitro a partir del tepache de piña.

The effects of four different cooking methods (steamed, boiled, deep‐fried, and grilled) on the proximate and fatty acid composition of rainbow trout were determined. The loss of water during the treatments increased the ratio of total fat and protein. The total content of polyunsaturated fatty acids (PUFAs) showed a significant change, increasing in the grilled samples. In contrast, there were no significant changes in the total amount of saturated and unsaturated fatty acids. The results showed that the major free fatty acid content in all the treatments was palmitic (C16:0), oleic (C18:1n9c), and linoleic acids (C18:2n6c). In addition, eicosapentaenoic acid (EPA) (C20:5n3) and docosahexaenoic acid (DHA) (C22:6n3) were the predominant n‐3 PUFAs in both the raw and cooked samples, but they were detected at low concentrations. Moreover, no significant change was observed in the n3/n6 ratio in all treatments. The highest index was 0.9026 ± 0.1804 in the grilled samples. Practical applications Fish farming plays a crucial role in boosting rural development and reducing poverty and hunger The vast majority of Atlantic salmon and rainbow trout consumed around the world are farmed intensively. However, the environment and feeding of the farmed fish is not the same in the different fish farming, causing changes in the nutritional values of the fish. In addition, the consumers have a minimal knowledge about the effect of the cooking method on the nutritional value. For this reason the study of the proximate and fatty acid composition of raw and cooking fish with a specific diet will help to professionals and fish farmers to improve the nutritional value of fish and the consumer could choose the healthiest cooking method.

Since ancient times, ginger (Zingiber officinale) has been widely used for culinary and medicinal purposes. This rhizome possesses several chemical constituents; most of them present antioxidant capacity due mainly to the presence of phenolic compounds. Thus, the physical conditions for the optimal extraction of antioxidant components of ginger were investigated by applying a Box-Behnken experimental design. Extracts of ginger were prepared using water as solvent in a conventional solid-liquid extraction. The analyzed variables were time (5, 15 and 25 min), temperature (20, 55 and 90 °C) and sample concentration (2, 6 and 10 %). The antioxidant activity was measured using the 2,2-diphenyl-1-picrylhydrazyl method and a modified ferric reducing antioxidant power assay while total phenolics were measured by Folin & Ciocalteu's method. The suggested experimental design allowed the acquisition of aqueous extracts of ginger with diverse antioxidant activity (100-555 mg Trolox/100 g, 147-1237 mg Fe2+/100 g and 50-332 mg gallic acid/100 g). Temperature was the determining factor in the extraction of components with antioxidant activity, regardless of time and sample quantity. The optimal physical conditions that allowed the highest antioxidant activity were: 90 °C, 15 min and 2 % of the sample. The correlation value between the antioxidant activity by ferric reducing antioxidant power assay and the content of total phenolics was R2 = 0.83. The experimental design applied allowed the determination of the physical conditions under which ginger aqueous extracts liberate compounds with antioxidant activity. Most of them are of the phenolic type as it was demonstrated through the correlation established between different methods used to measure antioxidant capacity.

In the bacterial processes involved in the mitigation of nitrogen pollution, an adequately high carbon-to-nitrogen (C : N) ratio is key to sustain denitrification. We evaluated three natural materials (woodchips, barley grains, and peanut shells) as carbon sources for low C : N wastewater. The amount of organic matter released from these materials to aqueous media was evaluated, as well as their pollution swapping potential by measuring the release of total Kjeldahl nitrogen, N- N H 4 + , N O 2 - , and N O 3 - , and total phosphorous. Barley grains yielded the highest amount of organic matter, which also showed to be the most easily biodegradable. Woodchips and peanut shells released carbon rather steadily and so they would not require frequent replenishment from biological reactors. These materials produced eluates with lower concentrations of nutrients than the leachates from barley grains. However, as woodchips yielded lower amounts of suspended solids, they constitute an adequate exogenous source for the biological treatment of carbon-deficient effluents.
