1. Prebiotic effect of commercial saccharides on probiotic bacteria isolated from commercial products
Abstract This study deals with the ability of probiotic bacteria to ferment prebiotics in vitro to estimate the prebiotic activity score and prebiotic index based on specific substrates and strains. Five probiotic bacteria were isolated from commercial products and their fermentation capability of three commercial prebiotics was assessed. Growth kinetics of

2. The Chemical Conversion of Biomass-Derived Saccharides: an Overview
Chemicals commodities and consumable, accounting for billions of ton of carbon per year, are produced in an industry based on non-renewable fossil feedstocks. Oil reserves are enough for feeding chemical industry for another century, and therefore, it is essential finding alternative sources of carbon for a progressive replacement of the industrial feedstock

3. Physicochemical characterization of saccharides powder obtained from yacon roots (Smallanthus sonchifolius) by membrane technology
Fructooligosaccharides (FOS) are food ingredients applied due to combination of prebiotic benefits and interesting technological properties, being used as a sugar substitute. The knowledge of their physicochemical characteristics is important for predicting the stability of the food products where they are added. For this reason, a saccharides powder extract

4. Classes of secondary metabolites identified in three legume species
The objective of this study was to identify secondary metabolite classes of tropical kudzu, perennial soybean and archer legumes through identification by phytochemical screening and confirmation by infrared (IR), ¹H and carbon-13 NMR spectroscopy of fractions obtained by organic solvents partition of crude extracts. These analyses allowed for proposing the

5. Desenvolvimento e validação de método analítico para quantificação de ácido pfáffico em Hebanthe eriantha / Development and validation of analytical method for quantification of pfáffico acid in Hebanthe eriantha
Hebanthe erianthe (Amaranthaceae) is known as "Brazilian ginseng¿, due to the similarity of its roots with those of Panax ginseng (Araliaceae), the "Korean ginseng¿. Its roots, with proved antineoplastic activity, are constituted by saponins, which during hydrolysis, release saccharides and free molecules of pfaffic acid, a nortriterpene. Pfaffic

6. A fast microwave-assisted procedure for loss on drying determination in saccharides
Um procedimento rápido para determinação de perda por dessecação (LOD) foi desenvolvido empregando aquecimento por radiação micro-ondas. Amostras de sacarídeos foram utilizadas e diferentes parâmetros foram avaliados, tais como a posição da amostra na cavidade do micro-ondas, massa de amostra e tempo de irradiação. Massas de amostra de 1 g e tem

8. Influence of physical and chemical caracteristics of plasticizers in the manufacturing and on the structural behavior and hygroscopic of films of calcium alginate / Influencia de caracteristicas fisicas e quimicas de plastificantes na confecção e no comportamento estrutural e higroscopico de filmes de alginato de calcio
Responsible consumers are looking for processed food with higher nutritional value and extended shelf live, without disregarding the damaging cumulative effects of sub products discharge on the environment. Biodegradable films are part of this concept. They are produced from natural polymers, mainly saccharides and proteins, with potential applications in th

9. Desenvolvimento e avaliaÃÃo da tecnologia de produÃÃo de Ãsteres homogÃneos de sacarÃdeos por acetilaÃÃo catalÃtica
As part of the systematic study of the process of acetylation of saccharides aiming to obtain products of industrial interests, we did tests with monosaccharides (glucose and fructose), disaccharides (sucrose). The sucrose composing abundant raw material deserves special attention as reagent acetylation of departure for a homogeneous environment. In the pres

10. Modelagem e validaÃÃo do processo contÃnuo de produÃÃo depoliÃis em reator de leito gotejante
In the present work a trickle-bed reactor was employed in order to perform a saccharide hydrogenation process to produce polyols in the presence of a nickel catalyst supported on activated carbon. The catalyst was prepared, characterized and tested. The reactor was assembled charged with the catalyst and the proposed reactions performed. A model was then pro

11. Relaxação em sistemas moleculares complexos / Relaxation in complex molecular systems
In this Thesis are presented studies by Molecular Dynamics simulations on some molecular systems presenting complex dynamics behavior (i.e., relaxation process caracterized by multiple time scales), including saccharides aqueous solutions, double helix DNA systems, air/water interfaces containing surfactants, and supercooled water. These systems, although cl
