Analysis of hemp products and cannabis

The popularity of products containing hemp (Cannabis) for industrial use (low in cannabinoids) is continuously increasing. Hemp seeds or protein powder produced from hemp are typical products available on the market. As the amounts of narcotic/psychotropic substances may differ considerably between different types of hemp it is crucial to know the exact content of these compounds in the product.
Analysis of these substances requires a special authorization by the Federal Opium Agency (Bundesopiumstelle) as the necessary reference materials belong to the group of narcotic/psychotropic substances. QSI holds this special authorization and is entitled to perform these analyses of hemp products.

Furan in coffee beans

Furan can be formed in foods during heat treatment, for example during coffee roasting. Furan has also been found in further heat-treated foods like bread or canned vegetables and canned meat. Amino acids and sugars are believed to play a key role in the formation of furan in foods.

Furan has been classified as possibly carcinogenic for humans by the International Agency for Research on Cancer (IARC), therefore the intake by humans should be as low as possible. Up to date there are no legal limits or indicative values for furan in foods. Please click here for more information.
