“…Lower transfer ratios of the pesticide residues were observed for licorice tea compared with the other matrixes. A similar trend was observed in the analysis of the water temperature dependence described above, and may be due to the presence of some natural components in licorice, such as pectin, starch, and proteins, which decrease the release of contaminants from plant tissue [ 28 ]. These findings highlight the significant influence of the infusion interval on the transfer of the pesticides, and further suggest that licorice can be considered as a relatively safer herbal tea.…”

The transfer of pesticide residues from herbal teas to their infusion is a subject of particular interest. In this study, a multi-residue analytical method for the determination of pyrethroids (fenpropathrin, beta-cypermethrin, lambda-cyhalothrin, and fenvalerate) in honeysuckle, chrysanthemum, wolfberry, and licorice and their infusion samples was validated. The transfer of pyrethroid residues from tea to infusion was investigated at different water temperatures, tea/water ratios, and infusion intervals/times. The results show that low amounts (0–6.70%) of pyrethroids were transferred under the different tea brewing conditions examined, indicating that the infusion process reduced the pyrethroid content in the extracted liquid by over 90%. Similar results were obtained for the different tea varieties, and pesticides with high water solubility and low octanol–water partition coefficients (log Kow) exhibited high transfer rates. Moreover, the estimated values of the exposure risk to the pyrethroids were in the range of 0.0022–0.33, indicating that the daily intake of the four pyrethroid residues from herbal tea can be regarded as safe. The present results can support the identification of suitable tea brewing conditions for significantly reducing the pesticide residue levels in the infusion.

“…Triazolone bioaccessibility decreased gradually with the addition of dietary fiber and protein in the stomach stage. However, in the intestinal stage, bioaccessibility slightly decreased with the addition of dietary fiber and protein, which might be due to bile powder and pancreatic enzymes in the intestinal juice inhibiting the ability of proteins and cellulose to absorb triazolone [ 17 ]. The bioaccessibility in the intestinal stage was less than that in the stomach stage, probably due to dietary fiber enhancing digestion, while protein did not.…”

“…Furthermore, studies have shown that a variety of factors can affect the bioaccessibility, including digestion time, pH, and solid–liquid (S/L) ratio [ 17 ]. When eating fruits and vegetables, other foods may also be ingested and mixed in the gastrointestinal environment, which could affect the bioaccessibility of pesticide residues in fruits and vegetables [ 18 ].…”

Estimating the influence of bioaccessibility of pesticide residues in fruits and vegetables on dietary exposure is a challenge for human health risk assessment. This study investigated the bioaccessibility of pesticide residues in cherry tomatoes and contributing factors (digestion time, pH, solid/liquid ratio, and dietary nutrition) using an in vitro test simulating the human gastrointestinal tract. pH had the largest effect on triazolone precipitation in the simulated gastric intestinal juice, which had a significant impact on the bioaccessibility. The bioaccessibility of triazolone in the intestinal stage was slightly higher than that in the stomach stage, owing to bile salts and pancreatic enzymes present in the intestinal juice. The bioaccessibility of triazolone did not change significantly with digestion time. In the gastric stage, there was a logarithmic relationship between the bioaccessibility and solid/liquid ratio (R2 = 0.9941). The addition of oil significantly changed the bioaccessibility in the gastrointestinal stage. Protein and dietary fiber only affected bioaccessibility in the stomach stage. Dietary nutrition can reduce the release of pesticides from fruits and vegetables into the stomach, sharply reducing the bioaccessibility, and the dietary exposure of pesticide residues in fruits and vegetables can be properly evaluated.

“…Only a part of the total content of trace elements present in the food matrix can be absorbed and utilized by the human body (Khouzam et al 2011). Therefore, beyond the determination of the total content in a food product, studies of metals should also consider their bioaccessibility (Peixoto et al 2016).…”

In recent years, açai berries (Euterpe Oleracea M.), goji berries (Lycium barbarum L.), bilberries (Vaccinium myrtillus L.), and chia seeds (Salvia hispanica L.) have increased interest worldwide due to their nutritional value and health benefits. In the present study, SEC-ICP-MS and μ-HPLC-ESI-MS/MS were used for the investigation of cobalt speciation and evaluation of its bioaccessibility in these products. Total cobalt content was determined, and açai berries (0.348 ± 0.042 μg g −1) and chia seeds (0.352 ± 0.036 μg g −1) were found as the best sources of this element. Different elution profiles of the extracts of examined berries and seeds obtained with the use of ammonium acetate, Tris-HCl, and SDS suggested that cobalt is bound by different bioligands in each biomatrix. The bioaccessibility of cobalt species was evaluated by SEC-ICP-MS. On the chromatograms of extracts obtained after simulation of gastrointestinal digestion, peaks corresponding to low molecular mass (17.00-1.35 kDa) cobalt complexes were observed. In the case of goji berries, their intensities were significantly higher on chromatograms of gastrointestinal than gastric extract. In enzymatic extracts, different forms of vitamin B 12 were identified by μ-HPLC-ESI-MS, including its natural forms-methylcobalamin (Me-Cbl) and adenosylcobalamin (Ado-Cbl).
