Acid Digestion of Plant-Based Food in Multiwave 5001 for the Determination of Trace Elements with ICP-MS Analysis
Rotor 24HVT50 in Multiwave 5001 allows for reliable and quick digestion of plant-based food based on FDA EAM 4.7 method to meet different requirements from all over the world.
Driven by a growing awareness of health benefits, environmental sustainability, and animal welfare, the rise of vegetarianism and veganism, coupled with advancements in food technology, has led to an explosion of plant-based alternatives to meat, dairy, and other animal products.
Today, plant-based foods are celebrated for their health benefits, including reduced risks of chronic diseases, and their lower environmental impact compared to animal-based foods. The global market for these products continues to grow, reflecting a shift towards more sustainable and ethical eating practices, rooted in a long history of plant consumption and cultivation.
Plant-based foods have diverse and complex matrices, including fibers, proteins, and carbohydrates, complicating the digestion, particularly when running different samples in one run.
Within this report the successful digestion of six representative food products on Multiwave 5001 with HVT50 vessels is described. To verify the stated method three of them were spiked and measured by ICP-MS. Currently the different standards for trace elements in these products differ from country to country and institution to institution. Therefore, combined “worst-case” limits were considered for the spiking experiment. For this purpose, three standards from Europe, India and the UN/WHO (see 6. References) were combined to give the maximum number of elements and the lowest limit for each element:
- Arsenic: 0.2 ppm
- Cadmium: 0.05 ppm
- Mercury: 1.0 ppm
- Lead: 0.1 ppm
