New Method in MOSH/MOAH Analysis
Special Material from LCTech for Fatty Foods!
As a supplement to the existing method EN 16995:2017, the German Society for Fat Science (DGF e.V.) published a supplementary method DGF-C-VI 22 (20) for MOSH/MOAH analysis in December 2020.
For the official method using on-line LC/GC (FID) analysis, the LOQs for fat-containing matrices did not give reliable data for ≤ 10 mg/kg total sum of MOSH/MOAH.
In order to be able to measure reliably also in the range up to 1mg/kg, in this new method the sample purification was supplemented by a 3 g SPE silica purification step with subsequent evaporation. Interfering compounds should be eliminated (before the epoxidation step specified in the still valid EN 16995:2017).
