The purpose of this study was to evaluate the physico-chemical characteristics, bioactive compounds and antioxidant activity of Malay apple fruit (Syzygium malaccense) grown in Brazil with regard to the geographical origin and its peel fractions and edible portion analyzed independently. Fruit diameter, weight, yield, and centesimal composition, ascorbic acid, reductive sugars, total soluble solids, pH and fiber content were determined. Total phenolics (1293 mg gallic acid equivalent/100 g) and total anthocyanins (1045 mg/100 g) contents were higher in the peel, with the major anthocyanin identified using HPLC-DAD-MS/MS as cyanidin 3-glucoside. Higher values for DPPH antiradical scavenging activity (47.52 μMol trolox equivalent antioxidant capacity/g) and Ferric Reducing Antioxidant Potential (FRAP, 0.19 mM ferreous sulfate/g) were also observed in the peel fraction. All extracts tested showed the ability to inhibit oxidation in the β-carotene/linoleic acid system. This study highlights the potential of Malay apple fruit as a good source of antioxidant compounds with potential benefits to human health.
Diante da situação caótica provocada pela pandemia da COVID-19, há uma proliferação de informações conflituosas, fazendo-se necessário o uso de estratégias eficazes para difundir conhecimento assertivo para a população. O relato de experiência, fruto de um projeto de monitoria, descreve a experiência de popularização cientifica através das redes sociais, como estratégia para o auxílio no combate ao COVID- 19. Foi produzido um vídeo informativo destinado aos estabelecimentos produtores de alimentos e posteriormente compartilhado nas redes sociais mais utilizadas pelos brasileiros: Facebook e Instagram. Verificou-se um grande número de visualizações do material publicado nos canais institucionais utilizados. Houve, portanto, uma boa difusão do conteúdo e constatamos a eficácia das redes sociais no processo de popularização científica durante essa pandemia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
