“…The role of these metabolites in health has been extensively studied during the last years. Yerba-mate extracts reduced the damage by DNA, lipid peroxidation and protein carbonylation in rats skin tissue induced by UVA and UVB radiation (Barg et al, 2014). The yerba-mate phytochemical profile may be greatly explored in the development of food products.…”

ABSTRACT. Yerba-mate (Ilex paraguariensis St. Hil.) is a native species of South America, and its dried leaves are consumed mainly as a beverage. Its phytochemical profile includes phenolic compounds consisting of secondary metabolites with antioxidant activities. Current research optimizes conditions of yerba-mate leaves oxidation, evaluates the sensory acceptance and assesses the in vivo antioxidant activity of the oxidized product. The variables incubation chamber humidity and age of leaves were optimized within the yerba-mate leaves oxidative process by a 2 2 factorial design. The sensory acceptance and the antioxidant activity of yerba-mate extracts, oxidized by the yeast Saccharomyces cerevisiae exposed to hydrogen peroxide, were assessed. The variables chamber humidity and age of leaves affected the colorimetric coordinates L* and b* during the oxidative process, and validated empirical models. The minimum concentration of beverage-type yerba-mate extract which was able to enhance the cell survival of S. cerevisiae was 150 μg⋅mL . Extracts from the two processing forms increased the cell survival in S. cerevisiae exposed to 5 mM hydrogen peroxide. The sensory acceptance of oxidized product did not differ significantly when compared to control. The antioxidant activity of yerba-mate extracts should be exploited for the development of new products.Keywords: oxidized yerba-mate, antioxidant activity, organoleptic proprieties.Atividade citotóxica / antioxidante e aceitação sensorial de erva-mate desenvolvida por processo de oxidação RESUMO. A erva-mate (Ilex paraguariensis St. Hil.) é uma espécie nativa da América do Sul, que tem como principal forma de consumo o chimarrão. Apresenta em seu perfil fitoquímico compostos fenólicos, metabólitos secundários com atividade antioxidante, o que representa uma condição capaz de estimular o potencial a ser explorado com sua utilização no desenvolvimento de novos produtos. Este trabalho teve por objetivo otimizar as condições de oxidação de folhas de erva-mate, avaliar a aceitação sensorial e a atividade antioxidante in vivo do produto oxidado. Foram otimizadas as variáveis umidade da câmara de incubação e idade da folha no processo oxidativo de folhas de erva-mate, através de um planejamento fatorial 2 2 . A aceitação sensorial, e a ação antioxidante de extratos de erva-mate tipo chimarrão e oxidada na levedura Saccharomyces cerevisae exposta ao peróxido de hidrogênio foram avaliados. As variáveis idade da folha e umidade da câmara exerceram efeito sobre as coordenadas colorimétricas L* e b* durante o processo oxidativo, validando modelos empíricos. A concentração mínima do extrato de erva-mate tipo chimarrão capaz de melhorar a sobrevivência celular em S. cerevisiae foi 150 μg⋅mL . Extratos obtidos a partir das duas formas de processamento foram capazes produzir aumento de sobrevivência de S. cerevisiae exposta ao peróxido de hidrogênio 5 mM. A aceitação do produto oxidado não se diferiu significativamente em relação ao controle. A atividade antioxidante dos extratos ...

“…has been known to cause different types of effects in biological systems ranging from oxidative damages caused by ionization products, free radicals, and reactive oxygen species (ROS) to damages to DNA and its interaction with macromolecules such as proteins (Chen et al, 2007;Swarts et al, 2007;Sharma et al, 2008;2009;Shuryak and Brenner, 2010;Cramers et al, 2011;Ramachandran and Nair, 2011;Sharan et al, 2011;Mukherjee et al, 2012;Barg et al, 2013;Francois et al, 2013). The interactions of these agents with cells has been shown to cause alterations in the gene expression pattern, mutations, weakening of repair mechanisms (Little, 2000;Sharma et al, 2009;Cramers et al, 2011;Mukherjee et al, 2012;Francois et al, 2013;Mikhailenko et al, 2013).…”
