Mango by-products are considered cheap sources of valuable foods and nutraceutical ingredients. In this work, antioxidant capacity (AOX), and potential absorption ability (PAA) of extractable polyphenols (EP) from mango by-product snacks (MB-S) were evaluated at different stages of in vitro gastrointestinal digestion. A wheat and oat-based control snack and three MB-S formulations (F1, F2 and F3) were prepared. Mango by-products were added at the expense of wheat in MB-S (paste-peel-seed): F1 (7...

Abstract Gastronomic differences between the countries cuisines around the world were largely defined due to the diversification of the use of spices and condiments during the European colonization of America, Asia and Africa. Hence, gastronomy tells the story of thousands of generations in a country and contains the culture of the population in multiple combinations of vegetables, types of meats or spices that depends on the geographical conditions. Particularly, the Mexican diet has been studi...

Mango (Mangifera indica L.) is a tropical fruit which is considered to be a source of dietary fiber (DF) and phenolic compounds (PCs). In this study, high DF mango-based fruit bars were developed from whole mango (peel and pulp). The bars were evaluated for their nutritional composition, the bioaccesibility of PCs during gastrointestinal digestion, and the PCs metabolites profile after in vitro colonic fermentation. The amount of DF in a 30 g portion of mango bars was 9.5 g, i.e., 35% of the rec...

AbstractThe indigestible fraction (IF) isolated from three lunch menus: Modified Mexican Lunch (MM-L), Traditional Mexican Lunch (TM-L) and Alternative Mexican Lunch (AM-L), was studied in terms of antioxidant capacity (AOX) and metabolites produced through fermentation by human intestinal microbiota. IFs were isolated after withstanding in vitro gastrointestinal digestion and total soluble polyphenols (TSP), condensed tannins (CT), hydrolysable polyphenols (HP) and AOX (DPPH, FRAP) were evaluat...

A Box–Behnken design (Extraction-time, pulse-cycle, sonication-amplitude) was employed to extract phenolic compounds from Justicia spicigera leaves by ultrasonic-assisted extraction. The muicle leaves extracts were analyzed measuring total phenolic compounds and antioxidant capacity. According to response surface methodology the optimal conditions of ultrasonic-assisted extraction to obtain the highest soluble phenolic content were 2 min (extraction time) for 0.7 s (pulse cycle) at 55% of sonica...

Se llevo a cabo la obtencion de extractos de hoja de carambola ( Averrhoa carambola L. ) con el objetivo de evaluar su actividad antioxidante y capacidad antifungica. La extraccion fue asistida por ultrasonidos. Se aplicaron tres diferentes tratamientos, donde el tiempo de extraccion, el ciclo de pulso y la amplitud de sonicacion fueron evaluados. Una vez obtenidos los extractos a las diferentes condiciones de sonicacion, se determino para cada uno de ellos el contenido de fenoles totales y la a...

Background and objectives: Food is the major factor driving the metabolism of the gut microbiota. In Mexico, nixtamalized corn products are widely consumed. Changes in antioxidant capacity (AOX) in 1,1-Diphenyl-2-picrylhydrazyl (DPPH) and Ferric ion reducing antioxidant power (FRAP), pH values, short-chain fatty acid concentration, and relative metabolite production during in vitro colonic fermentation of indigestible fractions (IF) isolated from Istmo Totopos (ITs), baked corn tortillas (BCTs),...

Abstract Mango (Mangifera indica L.) peel (MP), is a by-product from the industrial processing to obtain juices and concentrates, and is rich in polyphenols and dietary fiber (DF). DF content of dried MP is about 40%. The aim of this study was to determine the prebiotic potential of this by-product submitting predigested mango (‘Ataulfo’) peel to a dynamic in vitro model of the human colon. Dried MPs were predigested following an enzymatic treatment and separating digestion products and undigest...

Extracts of starfruit leaves (SL) were used with a response surface methodology (RSM) to optimize experimental conditions for ultrasonic-assisted extraction (UAE). A 33-1 fractional factorial design (extraction-time XET, pulse-cycle XPC and sonication-amplitude XSA) was employed for UAE, and SL extracts were characterized by total soluble polyphenols (TSP) content and antioxidant capacity (1,1-diphenyl-2-picryl-hydrazyl [DPPH], 2,2′-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) [ABTS] and f...
