4. Thermal degradation kinetics of ascorbic acid, thiamine and riboflavin in rosehip (Rosa canina L) nectar
Abstract In this paper, the loss of L-ascorbic acid, thiamine and riboflavin in rosehip nectar with the heating periods (0, 5, 10, 15, 20 and 30 min) at temperatures ranging from 70 to 95 °C is analyzed and experimental results are presented. Firstly, dried rosehip fruits were processed to rosehip nectar and then thermal treatment is performed. Liquid chrom

5. APPLICATION OF RESIDUAL YEAST AS A SOURCE OF REDOX MEDIATORS FOR THE ANAEROBIC DECOLORIZATION OF A MODEL AZO DYE
Abstract This work investigated the anaerobic degradation of the model azo dye Remazol Yellow Gold RNL in batch reactors using discharged residual yeast as the source of redox mediators (RM). Two yeast lysis methods (mechanical lysis and sonication) were tested and optimized to produce a riboflavin-rich yeast lysate. The reactors were operated at 25 ºC for

6. INFLUENCE OF THE APPLIED ORGANIC LOAD (OLR) ON TEXTILE WASTEWATER TREATMENT USING SUBMERGED ANAEROBIC MEMBRANE BIOREACTORS (SAMBR) IN THE PRESENCE OF REDOX MEDIATOR AND POWDERED ACTIVATED CARBON (PAC)
Abstract This paper evaluated the treatment of textile wastewater in submerged anaerobic membrane bioreactors (SAMBR) operated on a bench scale. Particularly, the influence of operational conditions, such as the applied organic rate (OLR) and the dilution factor (for toxicity attenuation) of the textile wastewater, was evaluated on color and organic matter r

7. Antioxidant, DNA damage protective, neuroprotective, and α-glucosidase inhibitory activities of a flavonoid glycoside from leaves of Garcinia gracilis
Abstract The leaves of Garcinia gracilis Pierre, Clusiaceae, have been used as flavouring materials in food, with no previous reports of their biological activities and chemical constituents. In this study, the methanolic extract of G. gracilis afforded three compounds namely apigenin-8-C-α-L-rhamnopyranosyl-(1→2)-β-D-glucopyranoside (1), 5-hydroxymethyl

9. The production of Pleurotus sajor-caju in peach palm leaves (Bactris gasipaes) and evaluation of its use to enrich wheat flour
The aim of this study was to evaluate of Pleurotus sajor-caju production in peach palm leaves and the addition of different fractions of mushroom powder to wheat flour to increase its nutritional value without changing its characteristics. The best yield (48.4%), biologic efficiency (4.5%), and Pr (0.36 g/day) values were obtained using 20% inoculum fraction

11. Modulação da agressividade do melanoma por flavinas / Modulating the aggressiveness of melanoma by flavins
Melanoma é o tipo mais agressivo de tumor de pele e uma das principais causas de morte por tumor de pele, devido a sua alta capacidade metastática. Em termos de estratégias terapêuticas de combate ao melanoma tem-se dado ênfase no controle da resistência e da metástase. Nosso grupo de pesquisa observou que a riboflavina irradiada (RFi) induz apoptose
