Quaternary Ammonium Compounds – Toxic Biocides in Ice Cream and Whipped Cream
Quaternary Ammonium Compounds (QACs) are chemicals that have two main applications:
1. Use as pesticides in plant protection products
2. Use as biocides in disinfectants
The main representatives of QACs are benzalkonium chloride (BAC) and didecyldimethylammonium chloride (DDAC). The use as a pesticide is prohibited in the EU.
Since 2013, the CVUA Freiburg has been routinely testing food for residues of BAC and DDAC and has detected these QACs in about 7% of the samples. The QACs were most frequently detected in light ice cream varieties and cream from vending machines. These QACs likely enter these foods through disinfectants that are not adequately rinsed off.
For BAC and DDAC, a provisional maximum residue level of 0.1 mg/kg applies. The LGL Bayern objects to ice cream starting from this maximum residue level.
In our Tentamus laboratories, we regularly conduct tests for QAC residues. We provide fast and reliable results. If you have any questions, our customer service representatives are happy to assist you.
