Testing the quality of dried fruits and nuts

Dried fruits and nuts are produced and processed in many different countries. Recently, more and more exotic fruits – such as Goji berries – are making their way to the market.

As typical agricultural products, dried fruits and nuts contain a variety of contaminants and harmful substances. Production, processing, transport and storage can lead to contamination with pesticide residues, heavy metals, mycotoxins or pest infestation.

At the same time, quality assessment, sensory analysis and separation of product quality class require extensive experience and knowledge of goods. Government regulations – such as those for pesticides, mycotoxins and SO2 – require regular inspections. Import controls on contaminants and goods from certain countries are mandatory.
