Fera’s contamination scientists are able to offer tests for a comprehensive range of Chloropropanols, including MCPD and DCP, with many test variants upon request. Fera’s food safety experts have many years of experience working with industry for contaminants testing, and can undertake bespoke studies tailored to your individual requirements, please contact us to learn more.


Monochloropropanols

3-MCPD (3-monochloropropane-1,2-diol), 2-MCPD (2-monochloropropane-1,2-diol) and glycidyl esters are a by-product of processing or refining edible oils and fats and are only relatively recent in their discovery. 3-MCPD and 2-MCPD are food processing contaminants formed by heat as a reaction product of triacyl glycerols, phospholipids or glycerol and hydrochloric acid in fat-based or fat-containing foods. Depending on the type of food it may occur as a free substance, in the form of an ester with fatty acids or in both forms. Glycidyl esters (GE) are compounds formed usually when refining vegetable oils at high temperatures, approx. 200°C. They may occur in margarines and vegetable oils, but also in low levels in bread, biscuits and malt based food ingredients. Recent studies by EFSA found the amount of 3-MCPD in the form of fatty acid esters in edible oils and fats ranged from around 500 to around 10.000µg/kg.

3-MCPD is a possible human carcinogen for which the Scientific Committee on Food has established a tolerable daily intake (TDI) of 2 µg/kg body weight. As such it is recommended to reduce the levels of 3-MCPD, 2-MCPD and their esters as much as possible. Scientific evidence has shown that 3-MCPD is released from 3-MCPD esters by regular digestion in the human digestive tract and therefore are considered to have the same toxicological profile as 3-MCPD (European food legislation - Commission Regulation EC 1881/2006). For soy sauce and hydrolysed vegetable protein the European Commission set a maximum level of 20µg/kg.

With various health implications associated with 3-MCPD, 2-MCPD and their esters there is a real need to control their levels within foods. Palm oil is naturally prone to higher levels of 2 and 3-MCPD esters due to the high levels of diglycerides. These high levels can be even larger through rapid soy protein hydrolyzation. With the wide range of uses associated with palm oil, including baby food and mayonnaise, as well as bakery products, the need for accurate testing is paramount. 2 and 3-MCPD esters and glycidyl esters occur in a variety of foods, most notably meats, infant formulae, and milk powders.


Dichloropropanols

1,3-DCP and 2,3-DCP are both potential carcinogens, and derivatives of 3-MCPD (3-monochloropropane-1,2-diol) and 2-MCPD which Fera can test for separately. These related compounds all belong to a group of chemical contaminants known as chloropropanols, most often produced in high-heat procedures. Samples of soy sauce, tested by the UK’s Food Standards Agency, found to contain high levels of of 3-MCPD were found to also contain 1,3-DCP. The most common food samples to contain 1,3-DCP are those where vegetable protein has been hydrolysed with acid (acid-HVP), this reacts with remaining lipids to form the chloropropanols. 1,3-DCP and 2,3-DCP can also occur where hydrochloric acid is used to speed up fermentation when some sauces are produced, this may be done to reduce production time and thus costs (e.g. soy, hoisin and oyster).


Accreditation

With testing accredited to ISO17025 by UKAS for 3-MCPD and 1,3-DCP and the ability to carry out testing for 2 and 3-MCPD esters, glycidyl esters and 2,3-DCP Fera is at the forefront of Food Process Contaminant testing. All testing is fully quantitative and results will be returned within 10 days of sample receipt.
