Contaminants in fats and oils: European Journal
The many sources of contamination like environmental effects, production machinery, and packaging materials are referred to and vegetable oils like sunflower, olive, palm oil, raw materials, and feed are focused on. The arguments for a reasonable limit for such contaminants in oils and fats are discussed.
Mineral oil hydrocarbon contaminations can often be found in oilseeds, oils, and fats as these matrices are good keepers to accumulate them from all kind of sources along the production chain.
Contamination of grape seed oil with mineral oil
The contamination of 11 commercial grape seed oils with paraffins of mineral oil origin was analyzed by online-coupled HPLC-HPLC-GC-FID and ranged from 43 to 247 mg kg(-1). The analysis of the marc and seeds indicated that the contamination is primarily from the peels. Since superficial extraction of the seeds with hexane removed most of the mineral paraffins, the contamination of the seeds is

Determination of Mineral Oil-Saturated
Determination of Mineral Oil-Saturated Hydrocarbons (MOSH) in Vegetable Oils by Large Scale Off-Line SPE Combined with GC-FID routinely detect mineral oil contamination in vegetable oils for
Vegetable oils are natural ester molecules with triglyceride structure, produced from the chemical linkage of three fatty acids to one glycerol molecule . The use of vegetable oils is increasing due to its advantages over mineral oils. Vegetable oils have high biodegradability,therefore they are more environment-friendly .
Mineral Oil hydrocarbons FEDIOL
Jointly under the FEDIOL umbrella, efforts have been made to develop best practices to prevent contamination. These best practices have been compiled in a FEDIOL Code of Practice for the management of mineral oil hydrocarbon presence in vegetable oils and fats intended for food uses.
The aim of this work is to inform about the development of a simple and reliable off-line method for the determination of saturated hydrocarbons (SH) in vegetable oils. SH can be used as markers for fuel or for mineral oil contamination in edible oils and fats.
PREVENTING THE TRANSFER OF Undesired Mineral Oil
results, e.g. with mineral oils from food additives or processing aids based on mineral oil. Often “humps” where the data is misinterpreted as MOSH in food and exclusively considered as “mineral oil contamination” will occur. Without scrutinising potential MOSH analogues specifi c to the product and process, this may lead to unjustifi
Contamination with mineral oils can occur at any stage of food processing, from harvesting, processing ingredients, and even during packaging. During the processing stages, machinery lubricants sometimes seep into food products. Processing of all vegetable oils such as canola,
- Do mineral oils contaminate food?
- Two types of mineral oils contaminate food: mineral oil aromatic hydrocarbons (MOAH) and mineral oil saturated hydrocarbons (MOSH). They need to be clearly distinguished, as according to the European Food Safety Authority (EFSA), the different groups of mineral oils, MOSH and MOAH, do not have the same toxicological potential.
- Are everyday foods contaminated with harmful mineral oil hydrocarbons?
- The results show that everyday foods are still contaminated with harmful mineral oil hydrocarbons and in some cases even to a considerable high extent. Of the products tested this year and bought in France, Germany, the Netherlands, Austria and Belgium, 19 products contained a concerning amount of mineral oil aromatic hydrocarbons, or MOAH.
- What causes contamination in edible oil?
- The various stages of edible oil production, packaging, transportation or storage, could cause contaminations in oils. In addition, the new industrial processes, agricultural practices, environmental pollution and climate change, new toxic residues in oil have been increasing ( Farré et al., 2013 ).
- Why is vegetable oil polluted?
- The use of fertilizers and pesticides containing heavy metals such as lead, mercury, cadmium, arsenic and other harmful substances have caused the oil to be polluted by heavy metals during the growth process. These pollutants are partly transferred into the oil during production, causing the pollution of vegetable oils.
- Are mineral oils bad for the environment?
- There is unavoidably a certain amount of background pollution in the environment. Mineral oils are also used specifically by the food industry, for example as anti-dust binders, lubricants in production machinery, mould release agents, and as polishes or in adhesives. The test published by foodwatch in 2015 covered dry food in cardboard packaging.
