Positive findings 2-Phenylphenol
2-Phenylphenol is a commonly used fungicide, which is mainly used for the surface treatment (preservation) of citrus fruits. 2-Phenylphenol has been detected more frequently in roasted coffee beans, while the same sample, only unroasted, showed no traces of this substance. The use of 2-phenylphenol in green coffee is not useful and therefore rather unlikely, as the coffee is storage-stable due to its residual moisture content. One study showed that small amounts of 2-phenylphenol can be produced by the roasting process. Therefore, a positive finding in roasted coffee does not necessarily indicate the use of non-compliant green coffee.
In such cases, an analysis of the green coffee used is recommended to confirm the result.
