Uso sustentado e processamento de llex paraguariensis St. Hill (Erva-Mate).
Valduga, Alice TeresaThe general objective of this thesis was to study the processing of maté Ilex paraguariensis St. Hil Lineage Cambona 4, a renewable natural resource of sustainable form of small farmers in the South of Brazil. An analysis becomes on the conception of the agricultural producers of the city of Machadinho-RS on environment and maté organic culture. A study of the mate processing is carried out initiating with the ...
Metabolic modeling and comparative biochemistry in glyoxylate cycle
Gonçalves, Itamar Luís; Mielniczki-Pereira, Albanin Aparecida; Piovezan Borges, Ana Claudia; Valduga, Alice TeresaGlyoxylate cycle in fatty acid catabolism enhances net production of oxaloacetate, a substrate for gluconeogenesis, in certain bacteria, invertebrates and oilseed in the growth stage. A theoretical model was developed to calculate ATP amount produced in each step of the catabolic pathway, taking into account the fatty acid’s hydrocarbon chain size. Results showed a decrease in energy efficiency in glyoxylate cy...
Cytotoxic / antioxidant activity and sensorial acceptance of yerba-mate develop...
Valduga, Alice Teresa; Gonçalves, Itamar Luís; Borges, Ana Cláudia Piovezan; Mielniczki-Pereira, Albanin Aparecida; Picolo, Ana PaulaYerba-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 oxi...
Quality of yerba-mate leaves originating from male and female plants
Rakocevic, Miroslava; Medrado, Moacir José Sales; Lavoranti, Osmir José; Valduga, Alice TeresaThe aim of this study was to assess the taste of beverage prepared from yerba-mate (Ilex paraguariensis) leaves, originated from male and female plants, by taking into account leaf gas exchange and the content of macro-and-trace-elements. Ecophysiological, chemical and sensorial properties were evaluated in one of the sprouting phases and in two fruit ripening phases. Male and female plants did not differ in fr...
