In this study, blueberry and blackcurrant powder were chosen as the phenolic-rich enrichments for oat bran. A Rapid Visco Analyser was used to form blueberry and blackcurrant enriched oat pastes. An in vitro digestion process evaluated the changes of phenolic compounds and the in vitro antioxidant potential of extracts of pastes. The anthocyanidin profiles in the extracts were characterised by the pH differential method. The results showed that blueberry and blackcurrant powder significantly increased the content of phenolic compounds and the in vitro antioxidant capacity of pastes, while the total flavonoid content decreased after digestion compared to the undigested samples. Strong correlations between these bioactive compounds and antioxidant values were observed. Lipopolysaccharide-stimulated RAW264.7 macrophages were used to investigate the intracellular antioxidant activity of the extracts from the digested oat bran paste with 25% enrichment of blueberry or blackcurrant powder. The results indicated that the extracts of digested pastes prevented the macrophages from experiencing lipopolysaccharide (LPS)-stimulated intracellular reactive oxygen species accumulation, mainly by the Kelch-like ECH-associated protein 1 (Keap1)/nuclear factor erythroid 2-related factor 2 (Nrf2) signalling pathway. These findings suggest that the bioactive ingredients from blueberry and blackcurrant powder enhanced the in vitro and intracellular antioxidant capacity of oat bran pastes, and these enriched pastes have the potential to be utilised in the development of the functional foods.

Abstract Pereskia aculeata Miller is a native cactaceae found from the Northeast to the South of Brazil. This plant is recognized by the high nutritional value of their leaves, which are the most used in cooking and folk medicine. However, studies on the chemical characteristics and antioxidant capacity of the ora-pro-nobis fruits are scarce. Therefore, the aim of this study was to determine the best harvest point of the ora-pro-nobis fruits to optimize the content of bioactive compounds and their antioxidant capacity. The fruits were manually harvested, defined by their peel colors in three maturity stages: unripe (green), intermediate (yellowish green), and ripe (yellow) stages. The following attributes were evaluated: soluble solids (SS), titratable acidity (TA), SS/TA ratio, pH, and content of bioactive compounds, such as total chlorophylls, carotenoids, yellow flavonoids, total phenolic compounds, and antioxidant capacity. There was a decrease in the content of chlorophyll followed by an increase in the of total carotenoids and yellow flavonoids, due to the maturity stage. For the total phenolic compounds, it was not observed significant difference between the stages. The antioxidant capacity was quantified by the ORAC method in lyophilized pulp in the unripe (1.95 mmol 100 g-1 trolox) and ripe (3.85 mmol 100 g-1 trolox) stages. The lowest contents were observed in the intermediate (0.80 mmol 100 g-1 trolox in lyophilized pulp) stage. The maturity stage significantly influenced the bioactive compounds of ora-pro-nobis, which presented higher values of total carotenoids, yellow flavonoids, and antioxidant capacity in ripe fruits.

Brazil is the third largest producer of fresh fruits in the world. Among fruits, berries such as strawberry, blueberry and blackberry can be highlighted for the benefits they provide to the body, owing to their presence of bioactive compound content. The phenolic compounds, especially anthocyanins and ascorbic acid, are examples of bioactive compounds that mainly function in the body as antioxidants. However, the processing steps that lead to the generation of derivatives from these fruits, are damaging to these compounds, often leading to their loss. Thus, the aim of this study was to physically and chemically characterize fresh berries (strawberry, blueberry and blackberry) and their jams, and also to quantify and to evaluate the antioxidant activity of bioactive compounds in berries and their jams. The following parameters were analyzed: moisture, ash, pH, titratable acidity, soluble solids, and color. The levels of total phenolic compounds, total anthocyanins, ascorbic acid content and antioxidant activity were measured. We concluded that there were significant differences in the chemical composition of berries and jams. There was also a significant loss of bioactive compounds due to processing, nevertheless these jams remain good sources of bioactive compounds, and are still considered important to promote some favorable health effects.

Abstract: The objective of this work was to evaluate the physicochemical composition, the bioactive compounds, and the total antioxidant activity of the fruit pulps of abiu (Pouteria caimito), achachairu (Garcinia humilis), araza (Eugenia stipitata), bilimbi (Averrhoa bilimbi), and yellow mangosteen (Garcinia xanthochymus) from the Brazilian Amazon biome. Total soluble solid content, total and reducing sugar contents, titratable acidity contents, pH, ascorbic acid content, moisture, protein, lipid, ash, and caloric value were determined. The contents of total anthocyanins, yellow flavonoids, and total carotenoids, besides total phenolic compounds and antioxidant activity, were also evaluated. The abiu pulp showed the highest contents of ash, total sugars, reducing sugars, total soluble solids, calorie value, and pH, among the analyzed fruits. The achachairu pulp showed the highest content of total phenolic compounds, with significant antioxidant activity, while the araza pulp had the highest total carotenoid content, and the yellow mangosteen, the highest yellow flavonoid content. The positive correlation between antioxidant activity and total phenolic compounds suggests that these compounds are the most important for determining antioxidant activity in the evaluated fruit pulps.

ABSTRACT Mexican plum (Spondias purpurea L.) ‘Cuernavaqueña’ was harvested at four ripening stages, with the aim of evaluating the concentration of bioactive compounds and antioxidant capacity in the pulp and the epicarp. The highest ethylene production (9.43 mL kg h-1) and total soluble solids concentration (23.9 °Brix) was observed in the fully ripe stage. Titratable acidity was higher in green stage compared to other analyzed ripening stages in both pulp (0.48 %) and epicarp (0.32 %). Fully ripe plum epicarp presented the highest content of total phenols (GAE 190 mg g-1), flavonoids (QE 214 mg g-1), and carotenoids (853 mg g-1) compared to other ripening stages. The antioxidant capacity was higher in the epicarp of the fully ripe fruit compared to the other ripening stages: DPPH (1087 µM TE /100 g), ABTS (1534 µM TE/100 g), and FRAP (1764 µM TE/100 g). Significant correlations (r = 0.60 *** to 0.95 **) between bioactive compounds concentrations and antioxidant activity were obtained.

Tomato is a fruit rich in bioactive compounds like lycopene, vitamin C and phenolic compounds. However, cultivation conditions can influence the concentration of these substances. In this study, the objective was to analyze quality characteristics of tomato fruits in different cultivation systems. The following characteristics were evaluated: pH, soluble solids content, total acidity, relationship between soluble solids content and total acidity, instrumental color parameters (L *, a *, b *, chroma and hue), texture, bioactive compounds (total carotenoids, lycopene, total phenolic compounds and vitamin C) and antioxidant activity of grape tomato fruits grown in a greenhouse in different systems (soil x substrate). A completely randomized design was used, with two treatments and four replications. The analysis were performed by official methods and in triplicate. The pH, soluble solids, texture, color, lycopene, vitamins C and antioxidant activity were not affected by the cultivation system used. However, grape-type tomatoes grown in substrate showed higher levels of carotenoids (36.31 µg.100 g-1 fresh matter), phenolic compounds (68.37 mg GAE.100 g-1 fresh matter) and ratio between total soluble solids and total acidity (17.90), and lower total acidity (0.58% citric acid 100 g-1), which represents a nutritional, sensorial and functional advantage for the consumer.

The fruits belonging to the family Myrtaceae are known sources of compounds with functional characteristics. Nevertheless, the studies are focused only on some species of this family. In this sense, we aimed to quantify the bioactive compounds present in the pulps of cambuci, feijoa, uvaia and grumixama; to evaluate the in vitro antioxidant capacity of each one and to correlate the contribution of these bioactive compounds with the antioxidant activity of each fruit pulp. For this, the compounds ascorbic acid, phenolic compounds, carotenoids, and flavonoids were quantified for the pulps of cambuci, feijoa, uvaia, and grumixama, as well as the in vitro antioxidant capacity by the methods DPPH and ABTS. The results were evaluated by multivariate statistical techniques. The pulps present good antioxidant potential, the one from cambuci presented the highest values for antioxidant activity given by the method DPPH (61.86 µg of Trolox g-1), that from uvaia was prominent by the presence of ascorbic acid (85.40 ascorbic acid 100 g-1) and that from feijoa, by the flavonoid contents (62.45 mg quercetin g-1) and phenolic compounds (10.21 mg gallic acid equivalent g–1). A correlation was observed between pulp antioxidant capacity and the contents of ascorbic acid and carotenoids; on the other hand, the phenolic compounds and flavonoids little contributed for the anti-free radical activity of the methods DPPH and ABTS.

SUMMARYBackground.In Mexico, it is called quelites to certain edible vegetables (young plants, germ, shoots or flowers). Since pre-Hispanic times, quelites have been eaten as a source of vitamins, minerals and proteins. Now, its traditional and healthy consumption has decreased. We studied the quelites of two traditional markets in the Valles Centrales of Oaxaca state, Mexico using an ethnobotanical and nutritional approach.MethodsFrom July 2017 to July 2018, weekly ethnobotanical interviews were conducted with 26 collectors-sellers of the Zimatlán market and 36 in the Zaachila market. The vegetal supply was acquired, herborized and identified by through dichotomous keys. There were determined the proximal composition, phenolic compounds, flavonoids, antioxidant capacity and mineral content of the floral structures of two quelites’ types. The statistical analysis was performed through a one-way analysis of variance (ANOVA) of Tukey HSD.ResultsIn two sampled markets, 23 species belonging to 11 botanical families were registered, from which leaves, branches, stems, flowers and fruits are eaten. The flowers of the species Diphysa americana (Q1) and Phaseolus coccineus (Q2) are the most used for human consumption of the communities involved in the sale of the sampled quelites. Both flowers had important amounts of proteins (2.66-3.29%) and fiber (1.66-2.43%). Q1 had higher content of phenols and flavonoids and therefore higher antioxidant capacity than Q2 (p <0.05). When we talk about Q2 minerals, it presented a greater amount of Zn, Ca and Mg in comparison to Q1 (p> 0.05).ConclusionsIn local markets of the state of Oaxaca, a wide variety of quelites are usually found, where their botanical structures, such as flowers, are widely eaten. The flowers of Q1 and Q2 proved to be a rich source of proteins and bioactive compounds, as well as minerals. Showing thus to be a food alternative to enrich the human diet.
