Multi-Element Assessment of Potentially Toxic and Essential Elements in New and Traditional Food Varieties in Sweden.

With the global movement toward the consumption of a more sustainable diet that includes a higher proportion of plant-based foods, it is important to determine how such a change could alter the intake of cadmium and other elements, both essential and toxic. In this study, we report on the levels of a wide range of elements in foodstuffs that are both traditional and "new" to the Swedish market. The data were obtained using analytical methods providing very low detection limits and include market basket data for different food groups to provide the general levels in foods consumed in Sweden and to facilitate comparisons among traditional and "new" food items.

Mild blanching prior to pH-shift processing of Saccharina latissima retains protein extraction yields and amino acid levels of extracts while minimizing iodine content.

The seaweed Saccharina latissima is often blanched to lower iodine levels, however, it is not known how blanching affects protein extraction. We assessed the effect of blanching or soaking (80/45/12 °C, 2 min) on protein yield and protein extract characteristics after pH-shift processing of S. latissima.

Inorganic arsenic in food products on the Swedish market and a risk-based intake assessment.

Inorganic arsenic (iAs) and total arsenic (tAs) were determined in common food from the Swedish market. Special focus was on rice, fish and shellfish products. For the speciation of iAs the European standard EN:16802 based on anion exchange chromatography coupled to ICP-MS was used.

Detection of lead nanoparticles in game meat by single particle ICP-MS following use of lead-containing bullets.

This study investigated whether game meat may contain nanoparticles of lead from ammunition. Lead nanoparticles in the range 40 to 750 nm were detected by ICP-MS in single particle mode in game shot with lead-containing bullets. The median diameter of the detected nanoparticles was around 60 nm.

Fast multi-element screening of non-digested biological materials by slurry introduction to ICP-AES.

A fast method for direct multi-element analysis of non-digested biological samples is presented. The only sample preparation needed is 1 min homogenization with a Polytron mixer in a small volume of neutral phosphate buffer saline solution (PBS). The total time for analysis (sample preparation and measurement) is 4 min only.
