| Bagaço de uva é uma boa fonte de compostos fenólicos, desempenhando capacidade antimicrobiana, sendo considerado um aditivo natural. Entretanto, compostos fenólicos são facilmente deteriorados, portanto o emprego da microencapsulação torna-se vantajoso, aumentando a estabilidade desses compostos. O trabalho avaliou o conteúdo de compostos fenólicos, antocianinas totais e monoméricas e a capacidade antioxidante do extrato de bagaço de uva concentrado (EBC) e microencapsulado (EBM), além do efeito desse pó como antimicrobiano em salsichas de pescado. O EBC e o EBM foram analisados, sendo o EBM a 0,5% (T0,5%) adicionado à formulação da salsicha que foi analisada microbiologicamente. Os resultados encontrados após a análise dos extratos foram superiores quando... |

| The consumption of berries has become a trend with confirmed health properties; however, fruit peels have been wasted despite their high concentrations of bioactive compounds. Tea made from jaboticaba (Myrciaria jaboticaba) peel (JP) could be an alternative to make use of this byproduct and contribute to increased intake of polyphenols. For this reason, this study investigated the JP chemical omposition and bioactive profile, as well as the antioxidant capacity of its aqueous extract (JPT e 25 g L1). The peel corresponded to approximately 35% of fruit weight. Total fiber content was approximately 30 g 100 g1, and the soluble portion represented 8.50 ± 0.21 g 100 g1. JPT showed strong antioxidant capacity according to all methods tested (FRAP, DPPH, and... |

| There is little knowledge about the phenolic compounds of hybrids grape cultivars reported in literature. This work aimed to characterize the bioactive and volatile compounds from new hybrids grape cultivars (Sweet sapphire-SS and Sweet surprise-SU). The antioxidant capacity and total phenolic content were evaluated using DPPH, ABTS, FRAP, ORAC and Folin – Ciocalteu assays, using water and acetone extracts. |

| Abstract: Modelling studies on climate change predict continuous increases in atmospheric carbon dioxide concentration [CO2] and increase in temperature. This may alter carbon-based phytochemicals such phenolics and modify plant interactions with herbivorous. We investigated the effects of enhanced [CO2] and local climatic variation on young coffee plants, Coffea arabica L. cv Catuaí vermelho IAC-144 and Obatã vermelho IAC-1669-20, cultivated in the FACE (Free-Air Carbon Dioxide Enrichment) facility under two atmospheric [CO2] conditions. Coffee leaves were evaluated for total soluble phenolics (TSP), chlorogenic (5-CQA) and caffeic (CAF) acids, diversity and population size of mites, along two dry and two rainy seasons. Elevated atmospheric CO2 (e[CO2])... |

| The objective of this work was to evaluate the effect of phosphites in the protection of common bean (Phaseolus vulgaris) against anthracnose. Different phosphite formulations were evaluated by quantifying peroxidase and polyphenol oxidase activity, total phenols, and lignin content. The treatments consisted of sprayings, in the V4, R5, and R7 stages, with: the K, Zn, Mn, K+Mn, K+salicyclic acid, and Cu phosphites; salicylic acid; acibenzolar-S-methyl; and the fungicide azoxystrobin; besides a control, without sprayings. The area under the disease progress curve was lower in plants that received applications of the K and Mn phosphites, whose values ranged between 74 and 81%, compared with the control. The K, Zn, and K+salicyilic acid phosphites were... |

| The grape pomace and wheat bran is rich in bioactive compounds that may be conjugated to the plant cell wall, making it difficult to recover. The objective of this study was to produce an enzymatic complex concomitant to the release of phenolics from grape pomace and wheat bran, by solid-state fermentation (SSF), using the mutant strain Aspergillus niger 3T5B8. Both substrates showed potential for the production of hydrolytic enzymes, mainly for xylanase and ?-glucosidase enzymes with grape pomace and wheat bran, respectively. In addition, SSF showed a more than 50% increase in the phenolic release of the substrates. |

| Myrciaria dubia, or camu-camu, is a perennial species that produces fruits of great nutritional interest because they have high levels of antioxidant compounds. The species occurs spontaneously on Amazonian river margins and requires a low amount of nutritional resources. Further, Myrciaria dubia fruits are collected via extractivism and managing this process is still at an incipient stage. The present study investigated the anatomical and histochemical aspects of the seeds of five clones of Myrciaria dubia. The external seed coat has an epidermis comprising a single layer of tabular cells that are rich in phenolic content, pectins, alkaloids, and terpenes. The cotyledons have a uniseriate epidermis, polyhedral parenchyma cells with a high concentration of... |
