Grape juices are rich in bioactive compounds; however, for these compounds to exert their functionality, they must be bioaccessible. Thus, the present study evaluated a simulated digestion process on the main bioactive compounds of monovarietal grape juices of five Brazilian hybrid cultivars (V. vinifera x V. labrusca). Characterization of the chemical profiles in liquid chromatography (HPLC-DAD-RID), behaviour of phenolics in the stages of digestion and bioaccessibility through the INFOGEST protocol plus intestinal barrier passage were carried out. Of the 24 polyphenols identified in the grape juice samples, 11 were bioaccessible, with emphasis on the class of flavanols. Procyanidin B2 (101?426%), (+)-catechin (169?370%) and gallic acid (61?230%) stood out in all juices, showing that these compounds are key to the functionality of these drinks. Particularities were observed to differ between juices, demonstrating that factors such as the cultivar should be explored more extensively in studies on functional foods. The study also suggests that quality components such as sugars and organic acids influence the bioaccessibility of beverages. |

Conservation management systems are usually suggested as alternative to restore the soil methane (CH4) oxidation capacity of degraded soils; however, little information is available on tropical and subtropical soils. Our objective was to evaluate the long-term (19 years) effect of no-tillage (NT) versus conventional tillage (CT) management systems on CH4 fluxes in a formerly degraded Acrisol in Southern Brazil. Annual CH4 fluxes of two cropping systems [O/M-black oat (Avena strigosa)/maize and V/M-vetch (Vigna sativa)/maize] were measured in NT and CT soils. Static chambers were used for air sampling, while chromatography was used for CH4 analysis. Analysis of the historical dataset at this experimental site indicated improvements in soil quality under the NT system, especially in legumebased cropping system (V/M) that exhibited the highest annual biomass input. CH4 fluxes ranged from ?42 ± 2 to 38 ± 16 ?g C m-2 h-1, and annual CH4 emissions ranged from ?825 ± 117 (CT V/M) to 453 ± 185 g C ha-1 (NT O/M). Thus, the annual CH4 oxidation capacity of the soil was not related to the soil quality produced by the soil management systems. On the basis of our results and published literature, we postulate that conservation management systems improve the methane oxidation and soil quality in distinct soil layers, which result in a slow effect of these management systems on the methane oxidation capacity. |
