Biofortification is an effective way to increase micronutrient levels in food crops. This study investigated selenium enrichment as a biofortification strategy in soybean sprouts. Chitosan oligosaccharide selenium nanoparticles (COS-Se NPs) were synthesized and used in soybean sprout culture to study their effects on the sprouts. The results showed that the enrichment factor value (EF) was higher when the concentration was 2.36−9.43 mg•L −1 compared with other concentrations, and the enrichment factor (EF) reached a maximum value of 0.9782 at a COS-Se NP concentration of 4.72 mg•L −1 . Translocation factors (TF radicle-hypocotyl and TF hypocotyl-cotyledon ) reached maximum values of 0.7866 and 0.9723 at 25.15 mg•L −1 and 15.09 mg•L −1 , respectively, suggesting the relationship between enrichment of nanoselenium and concentration was not proportional. Most of the organic selenium was present mainly in the protein fraction, and albumin and glutelin were the main protein-bound seleniums. The contents of protein and biomacromolecule selenium reached higher values at a COS-Se NP concentration of 2.36−9.43 mg•L −1 . Furthermore, the COS-Se NPs at 2.36−9.43 mg•L −1 concentration significantly affected the nutrient parameters in soybean sprouts. Different concentrations of COS-Se NPs were observed to have different effects on the mineral element content of the bean sprouts. In vitro digestion and dialysis experiments showed that the bioavailability of K, Mg, P, and Se was at a high level, while that of Fe and Ca was at a low level in soybean sprouts. Overall, no significant impact on the bioaccessibility of most elements was observed during the enrichment process compared to the control group. This work shows that the selenium enrichment strategy can be a potential soybean sprout production method and help solve the problem of nutritional deficiencies with selenium and reduce malnutrition.

Crayons and colored pencils for children may contain toxic elements (TEs) exhibiting potential risk for children?s health including cognitive development, after their ingestion, through mouthing and chewing and eventually, their accumulation. The aim of this study was to determine total content of As, Pb, Cr, Cd, Ni, and Sb and estimate their bioaccessibility conducting artificial saliva extraction. Sixty samples of colored pencils and crayons from 10 manufacturers were analyzed. Microwave acid assisted digestion followed by inductively coupled plasma optical spectroscopy (ICP-OES) was performed for determination of total content of TE. Simulation of extraction by artificial saliva was applied to get more reliable data when bioavailability is concerned. The total concentrations of TE were higher in colored pencils than in crayons and their maximum levels were: 5.78, 9.36, 9.97, 0.615, and 6.63 mg kg-1 for As, Pb, Cr, Cd, and Ni respectively. Concentration of Sb was below the detection limit for all investigated samples. This study showed that concentration of As and Pb in several samples did not comply with European Union regulative. Bioaccessibility study showed the high degree of leaching of Cr and As from pencils, but regardless of extracted portions, concentrations of selected investigated TE were below allowed levels.

“…Nickel is used as a catalyst to harden chocolates by hydrogenation of unsaturated fats [62]. Nickel is known to cause various adverse effects on human health, such as allergies, cardiovascular and kidney diseases, oxidative stress, and lung and nasal cancer [63]. These threats increase in line with the low age and bodyweight of the potential consumer.…”

Simultaneous extraction and colorimetric detection of ions using gel electromembrane

A total integrated electrocolorimetric sensing approach consisting of gel-based electromembrane extraction and colorimetric detection in one-step process was developed. This system was designed using colorimetric reagents preadded to the agarose gel for the determination of the following two model analytes: iodide for negative ions and nickel for positive ions. In this system, when a voltage was applied, the analytes were extracted and transferred from the sample solution (donor phase) to the gel (acceptor phase). The analytes then simultaneously reacted with the colorimetric reagents inside the gel, yielding blue and pink colors for iodide and nickel ions, respectively. These colors were then analyzed using a portable spectrometer for iodide detection and smartphone for nickel detection, which could also be distinguished with the naked eye. Parameters affecting the extraction efficiency were studied and optimized for both analytes. The gel composition for iodide detection was 4% (w/v) agarose, 5% (v/v) H2O2, and 1% (w/v) starch in 2 mM HCl. The gel composition for nickel detection was 3% (w/v) agarose and of 50% (%v/v) of 1:1 Dimetylglioxime (0.03 mM): Ammonia (80 mM) in agarose gel. Iodide and nickel were extracted at applied potentials of 50 and 70 V, and extraction time of 15 and 5 min and a stirring rate of 600 rpm, respectively. Under the optimized conditions, the developed systems provided linear responses within 15 min for iodide concentrations ranging from 50 to 250 ?g L-1 with a detection limit of 18 ?g L-1 and for nickel concentrations ranging from 30 to 750 ?g L-1 with a detection limit of 1 ?g L-1. Finally, these systems were successfully applied to the determination of iodide in iodide food supplement samples and nickel in chocolate samples, showing a negligible matrix effect. This integration could also be extended to other analytes and detection systems to develop sensitive, simple, and environmentally friendly sensing approaches.
