ABSTRACT: Companies develop strategies to describe where they want to go and how they will reach their destination. Business strategies are useful but may not be sufficiently detailed for areas of high importance, such as technology and innovation. In this paper we examined the effort of building a technology roadmap with an early growth stage comp...
The present work aims at studying the preconcentration of Cu2+ ions by solid phase extraction using SiO2/Al2O3/TiO2 ternary oxide as adsorbent material. This methodology consists of the affinity of the analyte for the adsorbent material and its subsequent elution with the least amount of solvent. Subsequently, the aqueous phase containing the extra...
Benzo[a]pyrene (BaP) is often used as a marker of polycyclic aromatic hydrocarbons (PAHs) in beverages. This marker is often quantified by chromatographic methods, which require sample preparations involving the use of reagents, solvents, extraction, pre-concentration, and/or cleanup steps. In this study, a new method for quantification of BaP in c...

Sugarcane spirits and cachaça are distilled beverages derived from the fermentation of sugarcane juice. The production of these spirits has significant influence on the economy of several regions in Brazil, being the third most consumed distilled beverage in the world. To ensure the safety for human consumption and also to add value to these produc...
The use of samples from students quotidian can get their attention for teaching contents to be presented. We have already presented a series of simple experiments demonstrating the use of flame atomic emission spectrometry in the determination of cations in samples present in our day life. Here sodium is determined in cachaça (sugar cane spirit), a...
Resumo: A cachaça é considerada uma bebida genuinamente brasileira, produzida em todo o território nacional e exportada para todos os continentes. Dada a sua relevância, propõe-se, neste trabalho, descrever o fluxo das exportações da bebida, destacando os países importadores e estados produtores, bem como a influência das políticas públicas e dispo...
Resumo Semelhante ao que se passa na Europa durante a Idade Moderna, foi frequente no Brasil colônia a atribuição de embriaguez aos grupos que promoveram protestos e rebeliões. O recurso discursivo pretendia desqualificar a legitimidade das reivindicações ao plasmar no imaginário político os rebeldes e a bebida alcóolica consumida por escravos.
The objective of the present investigation was to determine the percentage of removal of Total hydrocarbons of the petroleum using as bioremediation elements the residues of cachaça and bagasse of sugar cane. For the experimentation process, samples were collected from soils harvested from regions of the north of the country (oil zones); The experi...
ABSTRACT Objective: The aim of this paper was to identify the strategies developed for internationalization in order to create value in the artisanal cachaça sector of Brazil. Design/methodology/approach: A multiple-case study was applied in two artisanal cachaçarias. we carried out in-depth, semi-structured interviews with different stakeholders i...
This study carried out the assessment of physical, chemical parameters and the acceptability of pineapple (Ananas comosus L. Merri) liqueurs produced with “cachaça”, double-distilled, flavored “cachaça”with pineapple peels and grain alcohol. Analyses encompass alcohol content, density, pH, soluble solids total, fixed and volatile acidity, dry resid...
