Chocolate at Öko-Test: Many varieties are contaminated with mineral oil
The consumer magazine "Öko-Test" took a closer look at different types of chocolate and found that all residues contained mineral oil. Only one brand was hardly contaminated.
Mineral oil finds in food
For years, discoveries of mineral oil in food have always been reported. Mineral oil residues have been found in numerous advent calendars and in chocolate Easter bunnies in recent years. The report about mineral oil discoveries in Ferrero's children's bar caused a great stir. But even if the health hazards caused by these substances are repeatedly pointed out, the situation does not seem to improve: A current study by the consumer magazine "Öko-Test" showed that residues of mineral oil were present in all chocolate types tested.
Residues in all examined chocolate types
Whether white, dark or whole milk, with or without the addition of nuts, almonds and the like, conventional or organic: the consumer magazine “Öko-Test” has had a total of 40 chocolates examined in the laboratory and found any residues of mineral oil.
Mineral oil hydrocarbons come primarily from crude oil and are divided into two main groups: saturated mineral oil hydrocarbons (MOSH) and aromatic mineral oil hydrocarbons (MOAH).
Both can harm your health. The product testers also have good news for fans of the delicacy: the contamination of one brand was only minimal.
No limit values for carcinogenic substances
According to the experts, MOSH can accumulate in the lymph nodes, liver, spleen and adipose tissue and damage organs - in animal experiments, scientists have demonstrated damage to the liver and lymph nodes.
MOAH are even more of a concern: this group contains substances that can cause cancer in the smallest amounts.
According to the German Federal Institute for Risk Assessment (BfR) "there should be no detectable transition from MOAH to food."
However, there are no limit values for these contaminants at either European or national level.
According to a press release from the magazine, mineral oils can be transferred to food in various ways, for example via the cardboard packaging, if they consist of waste paper with printing inks containing mineral oil.
However, the cocoa beans can also come into contact with the substance at other points, for example through harvesting machines or through lubricating oils that are used in machine production.
Very different load for two products from one manufacturer
The laboratory analysis commissioned by "Öko-Test" shows "that all 40 chocolates in the test contain MOSH and one in four also contains MOAH," the message says.
"In our view, only a single chocolate is harmless because it is only minimally contaminated with mineral oil," the experts write on their website.
By far the highest contamination was in the Yes! Dark chocolate from Rewe. "Our division into" MOSH increased "," strongly increased "and" very strongly increased "falls short here because the measured value is ten times (!) Higher than our highest devaluation level," said the testers.
The different loads on the Aldi Süd brands Moser Roth and Choceur, which come from the same manufacturer, are very striking.
According to the information, all five Moser-Roth products contained “very high” MOSH levels, as well as MOAH.
It is interesting that the chocolate Choceur Feinherb Nuss from Aldi Süd, which comes from the same manufacturer - Storck - was the only variety that was so lightly loaded that it was not devalued.
Twelve chocolates were "only" criticized for their increased MOSH content. “In addition to the Aldi-Süd brand Choceur, Ritter Sport and Feodora attracted attention. Of the 13 chocolates rated "not loaded" or "slightly loaded", they are the least contaminated, "report the goods testers.
A manufacturer changed the packaging after the test
In its report, “Öko-Test” also referred to the reactions of the manufacturers. For example, Storck, whose Aldi Süd brand Moser Roth had noticed MOSH and MOAH in all five panels, sent counter-reports.
It was therefore surprising that these reports confirmed the analysis values of the laboratory commissioned by the magazine - within the normal range of fluctuation.
According to the "Öko-Test", Storck also announced that the packaging of the Moser-Roth tablets had been changed. Now there are still MOSH in the plates, but no MOAH are detectable.
Rewe, whose yes! Dark chocolate with the highest contamination in the test was evidently not self-critical: "The product is marketable and does not pass."
As "Öko-Test" announced, no overall rating was given in the investigation, since the chocolates were only examined for mineral oil, not for cadmium or other pollutants. (ad)
