Analysis Furan and Alkylfurans residues in food
Formation of Furan and Alkylfurans
Furan and Alkylfurans – a group of toxins that are generated during the processing of some products, especially those that use heat such as sterilization, roasting, baking, etc.
At the beginning of 2004, the Food Administration The United States Food and Drug Administration (FDA) has detected furan in a wide range of food products, especially canned and processed foods. Accordingly, studies show that toxins are formed from reducing sugars, amino acids, ascorbic acid, unsaturated fatty acids and carotenoids in food through the Maiard chain reaction. Foods commonly found in furans and alkylfurans are coffee, canned baby food, biscuits, breakfast cereals, crunchy snacks, potato chips, etc.
Why control Furan and Alkylfurans?
In terms of toxicity, Furan and Alkylfurans are heterocyclic aromatic, colorless, flammable and volatile organic compounds. The International Agency for Research on Cancer (IARC) has classified furan as a possible carcinogen and is concerned about the possible health risks associated with the occurrence of furans and alkylfurans in foods.
In October 2017, the European Food Safety Authority (EFSA) published a Scientific Opinion on “Public health risks associated with the presence of furans and methylfurans in food”. However, because the database on the presence of alkylfurans groups in food is still insufficient, EFSA recommends providing additional data on the alkylfuran group in parallel with the Furan index in foods.
On 28 March, the European Commission published recommendation number 2022/495, on monitoring for the presence of furans and alkylfurans in food. EU member states need to step up the supervision of food production and business establishments in monitoring furan, 2-methylfuran and 3-methylfuran, 2,5-dimethylfuran in food. In addition, depending on the specific product, it is possible to control the addition of some other alkylfurans (such as 2-pentylfuran and 2-ethylfuran) in food.
Technical analysis of Eurofins Sac Ky Hai Dang
For analytical techniques for the Toxin groups Furan and Alkylfuran, not only Eurofins Sac Ky Hai Dang but most other analytical laboratories still choose Headspace- Gas Chromatography-Probe Mass Spectrometry (HS-HC/MS). This is a method with stability and sensitivity that meets the minimum requirements set forth in EU 2022/495 (for coffee, the LOQ is not higher than 20 µg/Kg; for canned baby food and other products. other foods not higher than 5 µg/Kg).
In addition, to serve and meet the expanded screening of some manufacturers, Eurofins Sac Ky Hai Dang also expands its capacity and provides additional analysis of other alkylfuran compounds such as 2 -ethylfuran, 2-butylfuran, 2-pentylfuran.
