Fat Analysis: 17th Proficiency Test 2011

[30.11.2011]

Organised by the German Society for Fat Science (DGF) and Euro Fed Lipid.

Interlaboratory comparison tests serve laboratories to check applied methods and to recognize systematic errors. They are a central part of every quality assurance system. The DGF herewith announces the 17th interlaboratory comparison test for fat analysis to be carried out in 2011.

The samples will be dispatched in June 2011: A blend of different of vegetable oils and a fish oil, an olive oil and used deep-frying oil.

The following 22 parameters can be tested:

  • Acid Value (Free Fatty Acids)
  • Peroxide Value
  • Anisidine Value
  • Polar components in used deep frying fats
  • Polymerised triacylglycerols in used deep frying fats and non-refined vegetable oils
  • Butyric Acid
  • Tocopherol distribution, tocopherol content
  • Sterol distribution, total sterol content
  • Triacylglycerol distribution by GC
  • Triacylglycerol distribution by HPLC (New!)
  • Polycyclic aromatic hydrocarbons
  • Vitamin E and A content
  • Fatty acid composition (C8-C24, including EPA, DPA and Trans)
  • Chlorinated hydrocarbons
  • UV Absorption K232, K270 Olive Oil)
  • Pyropheophytine A (Olive Oil)
  • Isomeric diacylglycerols (Olive Oil)
  • Identification of an oil or of the components in a blend
  • Identification and determination of antioxidants (BHT, BHA,TBHQ,Gallates)
  • Phthalates residues in vegetable oils (New!)
  • Mineraloil residues in vegetable oils (New!)
  • Phosphorus (New!)


    • Each laboratory may choose an individual set of parameters from the list above. The execution and the evaluation of the laboratory comparison test are carried out according to the internationally recognized recommendations "Proficiency Testing Of Laboratories" of Codex Alimentarius and ISO regarding the check list for the IS0/IEC guide for 43-1 for "Proficiency Testing by lnterlaboratory Comparisons Part 1 (1996)".

    Participation Fee:
    The participation fee remains unchanged at 195 Euro + VAT (a reduced fee of 145 Euro applies for DGF or Euro Fed Lipid-corporate members).

    International Shipping of Samples:
