Analysis of microplastics in the foods

Current studies show that microplastics are increasingly being found in food, e.g. in sea salt or fish. Drinking water in plastic bottles can also contain microplastics.

WESSLING supports food and beverage industry customers in controlling the quality of their products with advice and precise analysis.Food manufacturers, distributors and retailers are increasingly faced with the challenge of also testing their products for microplastics as part of their high quality standards. WESSLING is one of the few laboratories with the necessary know-how and equipment for performing these analyses. The particles, which measure between one micrometre and five millimetres in size, can only be detected with the aid of sensitive methods. Our experts analyse your samples using recognised procedures, and are also on hand with their wealth of experience to provide advice.

We analyse foods for microplastics

Microplastics are increasingly occurring in certain foods such as sea salt. In current studies, researchers have detected up to 1,800 microgrammes of microplastics per kilogramme in sea salt, including polyethylene (PE), polypropylene (PP) and polyethylene terephthalate (PET), which are some of the main constituents of packaging refuse.

This result is attributable to the harvesting process: some sea salts form a thin layer of salt on the surface of the water. As microplastic particles are lighter than water, they float on the surface of the water and thus enter sea salt batches during the skimming process. We check and analyse your sea salt for contaminants such as microplastic particles so that you can ensure the high quality of your products.
