研究目的
The main goal of this work was the mineral composition profiling of selected commercial milk shake-style NDs and comparison of results with producer’s declarations as the important part of quality control and monitoring of these food supplements.
研究成果
Concentrations of Ag, Al, B, Ba, Ca, Co, Cu, Fe, Mg, Mn, Mo, Ni, P, Sr, Ti and Zn in eight varieties of milk shake-style nutritional drinks for the special medical purpose were assessed. Generally, assessed contents of the elements were similar to values declared on product labels. For Mo in all analyzed NDs samples and several other elements in single samples, discrepancies between experimental results and stated contents were noted, most probably due to differences in composition of substrates used for formula fabrication. Our investigations indicated that nutritional drinks should be considered as a significant source of main and trace elements in the human diet, which along with the presence of trace metals such as Ag, Al, B, Ba, Ni, Sr and Ti indicates the requirement for strict control of mineral composition in nutritional drinks.
研究不足
The study was limited to the analysis of mineral constituents in ready-to-drink nutritional supplements and did not assess the bioavailability of these minerals. The discrepancies between declared and measured concentrations of elements, especially for Mo, indicate the need for strict control of mineral composition in nutritional drinks.
