For frying, deep-frying or marinating: rapeseed oil is popular in the kitchen.
Ökotest has tested 23 refined and cold-pressed oils.
Read the results here.
The 23 rapeseed oils tested by Ökotest included products from discounters to organic suppliers, including both
refined
and
cold-pressed oils
.
The quality differs considerably, especially with regard to pollution.
In laboratory tests, some rapeseed oils were found to contain harmful ingredients such as PAHs (polycyclic aromatic hydrocarbons) and mineral oil *.
As a result, three rapeseed oils fail the test.
On the other hand, three oils received the top grade of “very good”.
Rapeseed oil: refined, cold-pressed, native - what's the difference?
Rapeseed oil can be used in many ways in the kitchen, is considered
healthy
due to its fat composition
and is relatively
cheap
to buy.
But there is a bit of confusion when it comes to the terms cold-pressed and refined.
Here is the difference:
Cold-pressed
refers to the method of production: the oils are extracted without the use of heat and
pressed
as gently as possible.
Refined
oils go through extensive physical and chemical processing steps that make the oil edible, tasteless and durable, as reported by Ökotest.
Advantage: This removes unwanted substances such as pesticides.
Disadvantage: Valuable ingredients and around 30 percent of the vitamin E content are also lost.
Oils that are completely untreated can be called
native
.
They are therefore characterized by an intensely seedy smell and taste as well as a slightly nutty note.
Cold-pressed, native rapeseed oil gives you the typical, fresh, seedy taste.
For everyone who doesn't like the taste of rapeseed oil: You should use refined oils, because they are tasteless.
At the same time, they contain just as many
valuable fatty acids
as cold-pressed rapeseed oil.

Rapeseed oils in the test: problems with mineral oil contamination
40 percent of the 23 rapeseed oils examined were only mediocre in the test.
Three products fail completely.
Ökotest mainly criticizes contamination with
mineral oil components
as well as with carcinogenic polycyclic aromatic hydrocarbons (PAH).
Ökotest explains that PAHs are formed when organic material is incompletely burned and can enter the food chain through exhaust gases or tire abrasion, among other things.
The majority of rapeseed oils that showed no PAH traces show that such contamination can be avoided.
Another big problem in many rapeseed oils in the test is mineral oil: only five products are free from it.
In eight rapeseed oils, however, the values were "greatly increased" according to the Ökotest criteria.
Mineral oil components can accumulate in human adipose tissue and the liver.
The consequences of ingestion for the human body have not yet been clarified.
And
how does mineral oil get into food products
?
"Mineral oil components can get into rapeseed oil from a wide variety of sources.
In the case of refined oils, examples of possible sources are residues of the extractant used.
Lubricating oils from oil presses can be a cause of both refined and cold-pressed oils, ”explains edible oil expert Dr.
Bertrand Matthäus from the Max Rubner Institute opposite Ökotest.
On the positive side, however, no
pesticides, fatty pollutants and plasticizers
(or only minor traces) were found
in the oils
.
None of the rapeseed oils tested was also adulterated or spoiled.

Ökotest examines rapeseed oils: These are the test winners
With
"very good" top rating
cut at Ökotest two refined and cold-pressed oil from:
the cheap, refined “Yes!
Pure rapeseed oil "from Rewe (96 cents per liter),
the refined “Feinkost Rapeseed Oil” from Kunella (2.58 euros) and
"Moritz Raps Kernöl cold-pressed, native" from Kleeschulte (promotional link) (7.58 euros per liter).
As is so often the case in life, the same applies here: good quality does not necessarily have to be expensive.
In addition to the very good oil from
Rewe
, the refined rapeseed oils from
Lidl
,
Edeka
and
Netto also
scored “good” in the test.
Tips on Proper Use of Rapeseed Oil
Store rapeseed oil in a cool and dark place, preferably in the refrigerator.
Native oils
are good for gently steaming and baking, but they are best to use in cold kitchens because the taste is retained.
Refined oil is recommended for frying as it is
highly heatable
