PFAS in Juices - chelab

PFAS stands for "per- and polyfluorinated alkyl substances". This refers to a large group of substances that, depending on the estimate, contains about 5,000 to 10,000 substances. These substances do not occur naturally, but are of anthropogenic origin.

"Due to their properties, such as high thermal and chemical stability, PFAS are also referred to as "forever chemicals"," explains Arne Dübecke, Managing Director of chelab Dr. V. Ara GmbH & Co. KG (chelab). They were developed for various applications for industry and used for decades. The substances are used in various consumer goods, for example in paints, coatings for leather and textile goods, clothing, carpets, packaging, car care products, as well as for the production of papers with grease-, water- and dirt-repellent properties. During production, these substances can be released directly into the environment or indirectly through the disposal of consumer products. PFAS are hardly degraded in nature and are very mobile, which has led to these substances being detectable almost everywhere in the world. The main entry into humans occurs through the ingestion of food. There they are deposited in organs, such as the liver. Some of these substances are thought to have a carcinogenic effect.

"So far, data on PFASs in groundwater and drinking water are primarily available. No data are available for fruit juices. However, the possibility cannot be excluded that PFASs enter the juice with the added water during the redilution of concentrates. It is also conceivable that PFASs could enter the fruit via the water absorbed by the plant," explains Simone Schmidt, managing director of chelab. For example, a US beverage manufacturer is currently facing a PFAS finding in orange juice.

"It is very important to us," continues Arne Dübecke, "to inform our customers about PFAS in good time and to help them understand the extent of possible contamination. Therefore, our team at chelab has taken up this issue and is currently conducting a study together with our partners at bilacon GmbH to get a first impression of the extent to which PFASs are also an issue for the fruit juice industry or whether the finding reported in the media is an exception."
