“…Samples of this juice showed high contents of Li and Na and low hue. These minerals might be incorporated to the reprocessed juice during dilution with water and addition of sugar and additives occasionally used (FERREIRA et al, 2002;FERRARI;SOARES, 2003;ASSIS et al, 2008). Indeed, the presence of high Na content is an indicative of the use 132.5 ± 62.6 45.7 ± 11.1 13.2 ± 6.9 5.2 ± 2.7 6.9 ± 3.8°B rix/Titratable acidity 20.8 ± 2.4 21.7 ± 3.7 24.2 ± 0.4 29.7 ± 5.8…”

The production and commercialization of Brazilian grape juice is increasing annually, mainly due to its typicality, quality, and nutritional value. The present research was carried out in view of the great significance of Brazilian grape juice for the grape and wine industry. The purpose of this study, therefore, was to assess its composition as well as the discrimination between grape juice and other beverages. Twenty four samples of whole, sweetened, and reprocessed grape juices, grape nectar, and grape beverage were evaluated. Classical variables were analyzed by means of physicochemical methods; tartaric and malic acids, by HPLC; methanol, by gas chromatography; minerals, by atomic absorption spectrophotometry. These products were discriminated by the Principal Component Analysis (PCA). Results show that whole and sweetened grape juices were discriminated from other grape products because they featured higher values of total soluble solids, tartaric and malic acids, most minerals, phenolic compounds, and K/Na ratio, whereas grape nectar and grape beverage presented higher values of ºBrix/titratable acidity ratio. Reprocessed juice was discriminated due to its higher concentrations of Li and Na and lower hue.

“…Food processing may increase the sodium content in food products not only by adding salt (sodium chloride), but also by the addition of additives that contain this mineral in their formulation, which aims to modify properties such as texture and flavor besides prolonging their shelf-life (FERRARI; SOARES, 2003).…”

“…234 U) in food-grade phosphoric acids (Table 3) and this intake, it is possible to estimate the intake of 0.59 ± 0.19 mBq day -1 . On the other hand, a heavy consumer of say 2 l day -1 of cola soft drink in Brazil (Ferrari and Soares 2003) would ingest about 6 ± 2 mBq day -1 , still well below recommended daily limits for U intake proposed by Health Canada (1999), the NCRP (1987), or the WHO (1998).…”

“…Unfortunately, there are neither data nor studies indicating the total annual intake of food-grade phosphoric acid per person through food, beverage, and pharmaceutical sources, which may contribute to internal ionizing radiation exposure in humans. To estimate this exposure, we considered that the most common use of food-grade phosphoric acid is in cola soft drinks, with an average consumption in Brazil of 72 l per person per year (Ferrari and Soares 2003). Each liter of cola soft drink contains 0.5 ml of foodgrade phosphoric acid, which gives an annual average intake of 36 ml of food-grade phosphoric acid per person.…”

Radionuclides from the U and Th natural series are present in alkaline rocks, which are used as feedstock in Brazil for the production of raw phosphoric acid, which can be considered as a NORM (naturally occurring radioactive material). As a result of the purification of raw phosphoric acid to food-grade phosphoric acid, two by-products are generated, i.e., solid and liquid wastes. Taking this into account, the main aim of this study was to evaluate the fluxes of natural radionuclide in the production of food-grade phosphoric acids in Brazil, to determine the radiological impact caused by ingestion of food-grade phosphoric acid, and to evaluate the solid waste environmental hazards caused by its application in crop soils. Radiological characterization of raw phosphoric acid, food-grade phosphoric acid, solid waste, and liquid waste was performed by alpha and gamma spectrometry. The (238)U, (234)U, (226)Ra, and (232)Th activity concentrations varied depending on the source of raw phosphoric acid. Decreasing radionuclides activity concentrations in raw phosphoric acids used by the producer of the purified phosphoric acid were observed as follows: Tapira (raw phosphoric acid D) > Catalão (raw phosphoric acids B and C) > Cajati (raw phosphoric acid A). The industrial purification process produces a reduction in radionuclide activity concentrations in food-grade phosphoric acid in relation to raw phosphoric acid produced in plant D and single raw phosphoric acid used in recent years. The most common use of food-grade phosphoric acid is in cola soft drinks, with an average consumption in Brazil of 72 l per person per year. Each liter of cola soft drink contains 0.5 ml of food-grade phosphoric acid, which gives an annual average intake of 36 ml of food-grade phosphoric acid per person. Under these conditions, radionuclide intake through consumption of food-grade phosphoric acid per year per person via cola soft drinks is not hazardous to human health in Brazil. Considering these annual additions of (238)U, (226)Ra, (232)Th and (40)K, and since these radionuclide should be homogeneously distributed in the upper 10 cm of soils with an assumed apparent density of 1.5 g/cm(3), a maximum increase of 0.19 ± 0.03 Bq kg(-1) of soil is expected for (238)U and (234)U. Thus, the addition of solid waste as phosphate fertilizers to Brazilian agricultural soils does not represent a hazard to the ecosystem or to human health.
