Special Issue Information

Dear Colleagues,

Elements enter the human body through diet, and hence, nutritional and sanitary quality of food and beverages is of special public interest and concern. It is important to monitor the level of toxic elements such as As, Cd, Hg, and Pb to ensure that they do not come into the food chain and do not pose any health risk to consumers, or, in case of detection of these elements, the current exposure level. Except for compliance evaluation of the aforementioned dietary products with regulatory allowable or approved limits for selected elements, information on the content of a number of physiologically important and essential major and minor elements, i.e., Ca, Cu, Fe, K, Mg, Mn, Na, and Zn, is helpful in assessing the nutritional value of these food products. It is possible to estimate daily uptakes of elements with food and beverages and, hence, contributions to realization of dietary reference intakes (DRIs) of elements resulting from their intake. Results of elemental analysis can bring useful tips to develop a balanced diet for a given age group. Finally, concentrations of elements determined in natural and low-processed food products and beverages can be useful variables in statistical evaluation of their provenience, geographical origin or the processing way. Here, any frauds in production, involving counterfeiting, replacing certain components or substrates with cheaper ones, or altering production methods or technology, can be reflected by changes in the element profiles of these products.

With all this in mind, it is clear that element analysis of food products and beverages is an important part of assessing and controlling their safty and quality. The current Special Issue is dedicated to analytical chemists dealing with element analysis of food and related products by spectrometric methods, food chemists, and bromatologists. Its aim is to cover interesting and valuable developments and achievements in element analysis of natural food products and beverages. Scientific areas to be covered by this Special Issue may include (but are not limited to) the following topics:

  • Rapid and non-destructive sample preparation procedures and new greenish methods of element analysis;
  • Speciation and evaluation of bioavailability of elements from food and beverages;
  • Element analysis of functional food, related products, and dietary supplements;
  • Monitoring of food and beverages for toxic elements and contaminants;
  • Grouping and classification of food and beverages using chemometric tools.

Original research papers and reviews covering all the above-mentioned topics are higly welcome.

The compositional authentication of wine is of great interest, as the geographic origin of the grapes is often associated with quality, uniqueness, and authenticity. Previous elemental fingerprinting studies mainly discriminated wines from different countries or regions within a country. Here, we report the use of element profiles to distinguish commercial Pinot noir wines from five sub-regional appellations or neighborhoods within one American viticultural area (AVA). Fifty-three single cultivar wines were collected over two harvests and analyzed using microwave plasma-atomic emission spectroscopy (MP-AES) and inductively coupled plasma-mass spectrometry (ICP-MS). Of 62 monitored elements that were quantified with fully validated methods, 24 and 32 elements differed significantly across the neighborhoods and vintages, respectively (p < 0.05). Targeted canonical variate analysis (CVA) explained 85%-90% of the variance ratio across the two vintages, indicating persistent and stable elemental fingerprints of wines at a sub-regional level. A sixth, newly founded neighborhood was correctly grouped separately from the others using a Soft Independent Modeling of Class Analogy (SIMCA), indicating the potential of elemental fingerprints for wine authenticity.

Commercially bottled birch saps (BSs) were analyzed for several nutrient (Ca, Cu, Fe, Mg, and Zn) and toxic (As, Cd, Ni, and Pb) elements using inductively coupled plasma optical emission spectrometry (ICP OES). The method was validated under the conditions of several sample preparation procedures, including a traditional digestion as well as alternative non-digestion schemes. It was found that the direct analysis of untreated BSs gives the best results, i.e., limits of detection at 0.02–5.8 ng mL−1, precision better than 5%, accuracy from 98.0% to 104.5% and determination of 12 elements in a short time (~1 min per sample). The multi-element analysis of nine commercially available bottled BSs showed that they contained mainly Mg and Ca, small quantities of Mn, Zn, Cu, and Fe, but are free from toxic elements such as As, Cd, Ni, and Pb. Additionally, the nutritional value of BSs was examined using in vitro gastro-intestinal digestion (GID) to determine the bioaccessible fraction of elements. Accordingly, bioaccessibility of nutritious ones (Ca, Cu, Fe, Mg, Zn) was <40%. Drinking daily 1 L of BSs covered <2.5% of recommended dietary intakes (RDIs) of the aforementioned elements. Only the bioaccessibility of Mn highly contributes to its RDI. Full article
