Acid Digestion of Plant-Based Food in Multiwave 7301 for the Determination of Trace Elements with ICP-MS
Multiwave 7301 provides reliable and fast digestion of plant-based food according to FDA EAM 4.7 method to meet different requirements around the world.
Driven by a growing awareness of health benefits, environmental sustainability, and animal welfare, the rise of vegetarianism and veganism, coupled with advances in food technology, has resulted in numerous 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 plant-based products continues to grow rapidly.
Plant-based foods have diverse and complex matrices, including fibers, proteins, and carbohydrates, complicating the digestion, particularly when decomposing different samples in one run.
Within this report the successful digestion of six representative food products with Multiwave 7301 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
