Fat Analysis: 16th
Proficiency Test 2010
by the German Society
for Fat Science (DGF) and the European Federation for the Science and
Technology of Lipids (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 16th
interlaboratory comparison test for fat analysis to be carried out in
2010. Regularly 100 laboratories take part.

different blends of vegetable oils, olive oil, animal
and fish oils

Fatty Acids)
- Peroxide Value
- Anisidine Value
- Polar components in
used deep frying oils and
fats
- Polymerised
triacylglycerols in used deep
frying fats and non-refined vegetable oils

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)".
