Wine is of particular interest nutritionally because it is typically low in sodium and relatively high in potassium. Sodium is the predominant cation in breakfast cereals, at levels reaching 8mg/g. Potassium and calcium also vary, particularly in wheat-based products and those enriched with milk products or calcium ...

Commercial cereals vary considerably in composition, both in their formulation and the ingredients added to enrich these products. Sodium is the predominant cation in breakfast cereals, at levels reaching 8mg/g. Potassium and calcium also vary, particularly in wheat-based products and those enriched with milk products or calcium salts. ...

The sample of biodiesel is weighed into a crucible and placed in a heating muffle furnace. Two temperatures are used in the heating program for the dry decomposition: the first temperature (250ºC) is maintained for 1 hour to dry the sample. After this the temperature is progressively elevated to 600ºC and maintained for 4 hours to eliminate the remaining organic material. ...

A number of methods have been reported for the measurement of calcium in biological materials by flame photometry or titration. This method employs trichloroacetic acid (TCA) to precipitate the proteins and has been found to be adequate to extract all of the calcium from tissue samples. Sodium, potassium and phosphate caused no significant interference and calcium concentration in the range of 0 to 2 µg/ml is readily determined. ...

In most cases, it was found that flame photometry was well suited for the determination of sodium, potassium and calcium in fresh fruits, using the wet ashing technique as given below. There are significant differences in the composition between different varieties of the same fruit, although these differences are not usually considered to be nutritionally ...

This technique allows use of aqueous standards for calibration rather than relatively unstable organometallic standards and harmful solvents for the extraction. Microemulsions are thermodynamically stable systems composed of water, oil and surfactant. In some cases, an alcohol is added as a ...

Preparation of Glassware: Thoroughly clean and rinse all glassware with the supplied BWB Technologies deionised distilled water to ensure that it is clean and free of extractable sodium and potassium. Glassware should be acid cleaned and rinsed thoroughly in deionised double distilled water prior to use to avoid contamination from extractable metals under ...

The effect of potential interference from other constituents of sea water was studied, including sodium, chloride and potassium. It was found that pre-concentration of the sea water was not necessary prior to analysis. A filtration of the sample was only necessary if sample contained suspended material. ...

The d-ROMs FAST Test allows the blood concentration of peroxides to be determined. Peroxides are a recognised marker of oxidative stress derived mainly from lipid oxidation (Cur Med Chem. 2005, 12:1161-1208.). Some classical molecules used as markers, such as MDA or isoprostranes, only identify the damage that has occurred, as they are the last products of oxidative processes. Peroxides, on the other hand, are the first products of oxidative processes, and among other things retain a certain pro-oxidant power ...

REDOX OB FAST enables the assessment of oxidative stress status through redox balance analysis. In every organism there is a delicate balance, called redox, between oxidising and antioxidising molecules. It is well known in the literature (Nat Rev Mol Cell Biol. 2020, 21:363-383.) that alterations in the redox balance, i.e. oxidative stress, are associated with numerous diseases, especially chronic or age-related diseases (diabetes, cardiovascular diseases, neurodegenerative diseases, …. ). In this context, ...

The PAT test allows the antioxidant power of the blood to be determined. As the antioxidant power of the blood is the first defence against the development of an oxidative stress condition, it is particularly useful to determine this. ...

The SAT test is used to determine the antioxidant power of saliva. As the antioxidant power of saliva is the first defence against the development of an oxidative stress condition, its determination is particularly useful. A substance with antioxidant capacity is defined chemically as a molecule with reducing properties. Reducing properties are not an absolute but a relative characteristic, so the choice of reference molecule becomes important. ...
