“…It was established that recoveries for all metals were quantitative within the following ranges: 94.7-103% and 98. 7 Only for Ca (BTL2 and BTL4) and for Ni (GTB5 and GTL2), precision was slightly worse, i.e., from 5.7 to 6.4%.…”

“…Respective relative errors for results obtained with this procedure (P2) in reference to results obtained using wet digestion (P1) were changed from − 49 to + 82% (BTB1) and from − 66 to + 44% (GTB1). In view of this, direct analysis of dialyzates (P2) could not be used for reliable determination of all metals in the bioaccessible fraction of tea infusions, although it was previously applied by many researchers [4][5][6][7][8][9][10][11]. Nevertheless, in cited papers, reliability of results of such analyses was not verified.…”

“…Bioaccessibility of different metals has been estimated so far in breads [4], fruits and vegetables [4][5][6][7], fruit juices [8,9], coffees [10][11][12], milks [13,14], herbal remedies [15], infant formulas [13,16], meat [17], linseed, sesame and cereals [16,18], and edible seaweeds [19][20][21]. Unfortunately, just few papers were devoted so far to bioavailability/bioaccessibility of selected metals from tea infusions.…”

A fast and straightforward sample preparation procedure of the dialyzable fraction of infusions of teas prior to their analysis on Al, Ba, Ca, Cu, Fe, Mg, Mn, Ni, Sr, and Zn contents by flame atomic absorption spectrometry (FAAS) and inductively coupled plasma optical emission spectrometry (ICP OES) was developed and validated. The proposed methodology was based on acidification with HNO 3 only and demonstrated good analytical performance, i.e., precision (0.80-5.0%), accuracy (< 5%), recoveries of elements (97.4-105%), and their detection limits (0.075-1.1 μg L −1 ) along with linearity of calibration curves in the whole studied concentration ranges. Applicability of the evaluated procedure, being a useful alternative to time-consuming wet digestions, was tested by determining bioaccessibility of elements in 20 infusions of black (BT) and green (GT) teas as assessed with the aid of in vitro gastrointestinal digestion. Average contributions of bioaccessible fractions (%) of studied metals were as follows: 1.18 (Al)-40.7% (Ca) and 4.65% (Al)-46.3% (Ca) for BTs and GTs, respectively. Drinking daily four cups (1 L) of tea, recommended dietary intakes (RDIs) of Ca, Cu, Fe, Mg, and Zn were covered to a small degree (< 1.5%). Only bioaccessibility of Mn highly contributed to RDI for this metal. According to provisional tolerable weekly intakes (PTWIs) for toxic elements such as Al and Ni, consumption of both types of teas should not represent any health risk. Additionally, analysis of variance of results clearly indicated that BTs and GTs were mostly differentiated due to concentrations of the bioaccessible fraction of Al, Ba, Cu, and Ni.

“…In recent years, in vitro gastrointestinal digestion has been applied to estimate bioaccessibility of elements from various food products and beverages, including fruit juices (Cautela et al 2009;de Lima et al 2014;Haro-Vicente et al 2006), infant formulas (Bermejo et al 2002;do Nascimento da Silva et al 2017), tea (Powell et al 1998;Erdemir 2018), herbal infusions (Pereira Junior et al 2018;Zhou et al 2014), GCs and ICs (Stelmach et al 2014(Stelmach et al , 2016, slim coffees (Szymczycha-Madeja et al 2015), chocolate drink powder (Peixoto et al 2013), various milks (Bermejo et al 2002;Chaiwanon et al 2000;Shen et al 1995), honey (Pohl et al 2012), fruits and vegetables (do Nascimento da Silva et al 2015;Khouzam et al 2011;Machado et al 2017;Oliveira et al 2018;Pereira et al 2016), breads (Gawlik-Dziki et al 2009;Khouzam et al 2011;Lamsal and Beauchemin 2015), cereals (do Nascimento da Silva et al 2017), white cheeses (Khouzam et al 2011), various meats (Menezes et al 2018), and edible seaweeds (Dominguez-Gonzalez et al 2010;García-Sartal et al 2011. Commonly, a two-step procedure that simulates stomach and intestinal digestion with solutions of pepsin in the gastric phase and a mixture of pancreatin and bile salts in the intestinal phase is used.…”

Method Validation for Multi-Elemental Analysis of Dialyzable and Non-dialyzable Fractions of Coffee Brews by F AAS and ICP OES: a Bioaccessibility Study

A simple and fast, non-digestion treatment, and fully validated preparation procedures of dialyzable and non-dialyzable fractions of brews of ground (GCs) and instant (ICs) coffees prior to their elemental analysis (Al, Ba, Ca, Cr, Cu, Fe, Mg, Mn, Ni, Sr, and Zn) by flame atomic absorption spectrometry (F AAS) and inductively coupled plasma optical emission spectrometry (ICP OES) was developed. Three different procedures: wet digestions (P1), direct analysis (P2), and acidification with HNO 3 (P3) were tested. Among tested procedures, the direct analysis (P2) gave the most satisfactory results, i.e., precision from 0.54% (Fe) to 5.9% (Cu), recoveries ranging between 98.0% (Sr) and 104% (Al), detection limits within 0.095 (Ba)-1.8 (Ni) μg L −1 , and quantification limits from 0.32 (Ba) to 6.0 (Ni) μg L −1. The chosen procedure was applied to determine bioaccessibility of 11 elements in GCs and ICs coffees using in vitro gastrointestinal digestion. Average contributions of the bioaccessible fraction (%) of elements in brews were as follows:

“…However, this is not sufficient as it is necessary to know about the bioaccessibility of each element. Bioaccessibility refers to the percentage of the ingested amount of the element that potentially can be absorbed during the digestion process and subsequently transformed into metabolically active species [9,10].…”

In this study, the total concentration and bioaccessibility of four metals (Zn, Se, Cd, Cu) in sea cucumbers () before and after cooking were measured. The concentration of Zn, Se, Cd, and Cu were 22.24 ± 0.75, 0.75 ± 0.06, 0.32 ± 0.07, and 1.88 ± 0.09 mg/kg in raw cucumber, respectively. The contents of Zn, Se, and Cu in high-pressured samples were significantly higher than that in the raw sea cumber ( < 0.01). The levels of Cd were all decreased after three thermal treatments. The intake of Zn and Cu increased in sea cucumber cooked by all thermal processes. While the bioaccessibility of Se and Cd decreased after cooking. A significant correlation was observed between the concentration and bioaccessibility of minerals. These data provide useful information for dietary risk assessments of minerals in sea cucumbers.
