Abstract The dataset showed in this manuscript belongs to the investigation of the Southern-Brazilian geopropolis of stingless bees. Stingless bees are native species of insects from tropical areas; they produce honey, pollen and geopropolis that is composed of a mix of vegetal extracts, digestive enzymes, and mostly by soil. Used in folk medicine as antiseptic, antioxidant and antimicrobial agent, the composition is due to bee species, climate changes, local flora, and soil type. Moreover, the ...

Abstract Geopropolis is a stingless bee product compose mainly by soil, presenting complex composition geopropolis has bioactive compounds that will depend on geographical characteristics as well bee species, changing their chemical and biological properties. Thus the study aims to evaluate the solubility and chemical stability of geopropolis extracts, through radical capture capacity and reducing capacity. Besides, analysis of free and bonded phenolic compounds, and mineral composition. Geoprop...

Abstract Background The development of statistical software has enabled food scientists to perform a wide variety of mathematical/statistical analyses and solve problems. Therefore, not only sophisticated analytical methods but also the application of multivariate statistical methods have increased considerably. Herein, principal component analysis (PCA) and hierarchical cluster analysis (HCA) are the most widely used tools to explore similarities and hidden patterns among samples where relation...

A simple strategy using an atomic absorption spectrometer (AAS) for the direct determination of molecular compounds is proposed. The determination of caffeine and propranolol employing atomic absorption instrumentation was conducted, monitoring the emission lines of Fe (271.9 nm) and Mg (285.2 nm), respectively, using a quartz cuvette (1.0 cm) positioned in the burner head. Samples or standards were inserted into the cuvette in order to obtain the absorbance measurements. The parameters of merit...

The french bread is the bakery product is mostly co nsumed in Brazil, basically prepared with wheat flour, water, salt and improver . The aim of this study was to analyze physico- chemical and sensory formulations enriched French bread with fiber and low salt content. The breads were subjected to analysis of moisture, ash, protein, lipid, crude fiber, sodium and potassium. The sensory acceptability analysis was a pplied using the nine-point hedonic scale, with no trained judges. Sample C had the...

Summary In recent years the consumption of chocolate powder has been increasing, mainly by kids, and for this reason quality control of the product in relation to its composition, especially regarding the mineral concentrations, is important to facilitate the choice of product by the consumers. A simple and quick method for the determination of Fe, K and Na in chocolate powder samples using ultrasound assisted extraction was proposed. The measurements were carried out using photometric detection...
