Avoiding Contamination of Chocolate in Advent Calendars

Behind the doors of advent calendars, chocolate treats are hidden for every day until Christmas. It is a ritual that is repeated every year during the pre-Christmas period. The colorfully printed calendars are especially popular with children.


However, Tests showed that the chocolate is often contaminated with mineral oils.


In fact, the testers found mineral oils and related substances in calendar chocolates – though in varying quantities. The substances are so-called aromatic mineral oils – some of these substances are suspected of being carcinogenic.


Oils accumulate in the body


As far as the limit values of such substances are concerned, the EU has not yet adopted a directive. Short-chain non-aromatic mineral oils can accumulate in the human body and could lead to liver diseases.




Where does the mineral oil in chocolate come from?


The main source of the mineral oils is considered the cardboard that surrounds the chocolate. It is usually made from recycled paper and contains inks with mineral oil from newspaper printing. If the cardboard lies on the chocolate, these oils can get into the sweets.

Since chocolate consists of a lot of fat, substances easily accumulate in it. Also, additional oils that manufacturers use to lubricate their machines could get into the chocolate and thus in the human body.


Which steps can manufacturers take?


Manufacturers should have their calendars checked for residues of mineral oils (MOSH/MOAH).
