Differentiation of Confectionery Products Based on Mineral Composition
The aim of this investigation was to introduce multivariate techniques for the estimation of confectionery product quality in view of their mineral composition. The concentrations of 14 elements (Ca, Mg, K, Na, P, Co, Mn, Fe, Cr, Ni, Zn, Cu, Cd, and Pb) were determined in confectionery products after wet digestion with nitric acid in an automatic microwave digestion system. The total metal contents were analyzed by flame atomic absorption spectrometry using deuterium background correction. Phosphorus was determined in the form of phosphomolybdate by a spectrophotometric method. Reliability of the procedure was checked by analysis of the certified reference materials tea (NCS DC 73351), cabbage (IAEA-359), and spinach (IAEA-331). Significant correlation coefficients were found between concentrations of Mg, Zn, Ca, K, Na, P, and Fe in the samples analyzed. Application of ANOVA Kruskal–Wallis test revealed dependence between sugar biological provenance and its elemental composition. Macro- and microelement levels in chocolates were significantly influenced by the cocoa content in the final product as well as its geographical origin. Factorial and cluster analyses were applied to the data in order to characterize elemental content of the confectionery products. Based on the mineral composition, it was possible to differentiate chemometrically particular types of sugar, cocoa, and chocolates, which is important from the food authenticity point of view.
Plant parasitic nematodes are the most destructive group of plant pathogens worldwide and their control is extremely challenging. Plant Essential oils (EOs) and their constituents have a great potential in nematode control since they can be developed for use as nematicides themselves or can ... more
For over a century, ulcer has been a major cause of morbidity and mortality. Its treatment has progressed from vagotomy to proton pump inhibitors. However, the drugs used produce many adverse effects and are less effective than they ought to be. Therefore, there is a growing interest in alt ... more
Endophytic fungi are ubiquitous organisms found in the plants, residing intercellular or intracellular, at least for a portion of their lives without causing apparent symptoms of infection. Almost all plants are known to harbor endophytes. The choice of the plant to be used for exploring en ... more

Inflatable toys and swimming aids, like bathing rings and arm bands, often have a distinctive smell which could indicate that they contain a range of potentially hazardous substances. Some of these compounds, which include carbonyl compounds, cyclohexanone, phenol and isophorone, might be c ... more
