“…Previous studies reported inhibition against S. aureus with extracts of camu-camu and P. granatum (Azevedo et al, 2014;Fujita et al, 2013;Machado et al, 2002;Myoda et al, 2010;Pradeep, Manojbabu, & Palaniswamy, 2008). According to Caillet, Côté, Sylvain, and Lacroix (2012), cranberry phenolic compounds had significant inhibitory effects on S. aureus, Gram-positive bacteria where destabilization of cytoplasmic membrane, permeabilization of plasma membrane, inhibition of extracellular microbial enzymes and metal binding capacity could be reasons for the inhibition.…”

“…1). The phenolic compounds found in camu-camu are quercetin, cyanidin-3-glucoside, ellagic acid and ellagitannins (Azevedo, Fujita, Oliveira, Genovese, & Correia, 2014;Chirinos, Galarza, Betalleluz-Pallardel, Pedreschi, & Campos, 2010;Fracassetti et al, 2013;Genovese, Pinto, Gonçalves, & Lajolo, 2008;Gonçalves, Lajolo, & Genovese, 2010;Rufino et al, 2010). This fruit has also shown high antioxidant activity and can be utilized against pathogenic bacteria responsible for human infectious diseases (Fujita, Borges, Correia, Franco, & Genovese, 2013;Gonçalves et al, 2010;Inoue, Komoda, Uchida, & Node, 2008).…”

Camu-camu (Myrciaria dubia (Kunth) Mc. Vaugh (Myrtaceae)) has shown potential for food and human health applications due to its rich bioactive functional properties linked to high antioxidant activity. The main objective of this study was to identify antioxidant-linked bioactive phenolic profiles in spray-dried and freeze dried camucamu pulp and to evaluate potential functionality associated with anti-hyperglycemia and anti-hypertension properties using in vitro enzyme assay models. Further, antimicrobial properties and planarian-based cellular protection and regeneration were also investigated. Phenolic compounds, such as ellagitannins, ellagic acid, quercetin glycosides, syringic acid and myricetin were detected in camu-camu by LC-TOF-MS. Freeze dried camucamu powder showed superior phenolic-linked antimicrobial properties and higher hyperglycemia relevant enzyme inhibitory activity compared to the spray dried samples. Besides that, freeze-dried powders and spraydried (6% gum arabic at 120°C) powders were more effective against prokaryotic Staphylococcus aureus and showed higher inhibition than ampicillin. Cellular regeneration of eukaryotic planarian model was stimulated with camu-camu powders when compared to control and showed potential of camu camu for redox-linked cellular protection and rejuvenation. Overall camu-camu rich in phenolic bioactive profiles showed superior antidiabetic and antimicrobial properties and has potential as part of dietary strategies in the management of early stages of type 2 diabetes and associated complications.

This study addressed the physicochemical characteristics and selected bioactive compounds of tropical fruit pomaces acerola (Malpighia glabra L.), red pitanga (Eugenia uniflora) and jambolan (Syzygium cumini) obtained by spouted bed drying. The dried pomaces presented attractive colors, acidic pH, moisture between 8.3 and 9.7 g/100g, water activity lower than 0.5 and solubility around 40%. The water and ethanol extracts of these fruit powder samples showed high concentration of phenolics (10.1–30.7 mg GAE/g) with relevant DPPH (2,2‐diphenyl‐1‐picrylhydrazyl) antioxidant activity (30.1–36.3 μmol Trolox equivalent/g). Dried jambolan also proved to be an outstanding anthocyanin‐rich product (377.0–478.7 mg cyanidin 3‐glycoside equivalent/100g). In addition, all extracts presented intermediate α‐amylase inhibitory activity (23.9–76.6%) and remarkable in vitro effect against α‐glucosidase (up to 99.3%). Overall, our results show the bioactive and technological potentials of dried acerola, red pitanga and jambolan pomaces as high quality food ingredients with functional attributes. Practical Applications Acerola, red pitanga and jambolan are bioactive‐rich tropical fruits. The fruit processing generates a considerable amount of low‐value fruit pomaces. The motivation for this research was to propose the spouted bed drying as an appropriate strategy to produce food ingredients using the abundant residues of these selected fruits. A relevant concentration of residual bioactive compounds, antioxidant activity and inhibitory activities against key enzymes relevant to the management of early stages of type 2 diabetes were detected in the final dried products. Overall, our results present the spouted bed drying as a promising eco‐friendly process that can be successfully applied to produce value‐added fruit co‐products with potential health benefits. The data presented here constitute the biochemical rationale for the better exploitation of these tropical fruit pomaces.

Camu‐camu (Myrciaria dubia) fruit is a rich source of bioactive compounds but its shelf life is rather short. Therefore, this study was aimed to evaluate the effect of inlet air temperature (T) and concentration (C) of maltodextrin and arabic gum on the spray‐drying process of commercial camu‐camu pulps (São Paulo and Manaus). Moisture, solubility, total phenolics (TP), ascorbic acid (AA), and proanthocyanidins (PAC) contents, and in vitro antioxidant capacity of the powders (FRAP, DPPH, Folin–Ciocalteu's reducing capacity were measured). Arabic gum resulted in better yields (22% to 30%), powder solubility (84% to 90%), and lower losses of analyzed compounds than the powders manufactured with maltodextrin. Overall, inlet air temperature had a lower impact on the responses studied than the concentration of carrier agents. Polynomial equations were generated for AA (R2 = 0.993), TP (R2 = 0.735), PAC (R2 = 0.946), and for the antioxidant capacity assays (0.867 ≤ R2 ≤ 0.963). In addition, principal component analysis showed that the lowest concentration of carrier agents (6%) in spray drying resulted in the lowest losses of bioactive compounds and, consequently, the highest antioxidant capacity.
