Hi! The exporters of oil to the European
Union must know which MRL (maximum
residue limit) applies to the oil. So if
you look for in the database of the
European Union about oil you will find
nothing. Why? Because the European Union
does not publish MRLs for processed
items just for raw commodities. So if
you want to calculate
the MRL for oil you need two things
Firstly, you need the MRL for the raw comomodity and secondly the
processing factor of that oil. So let's
see an example. Imagine that  we would like
to find out which is the MRL for
soybean oil
regarding the active pyraclostrobin
as you see here the MRL is 0.2 ppms
and now let's find the processing factor
we can go to the source FEDIOL which is
the European Union producers of oil and as you
see here in this table the processing
factor for soybean oil is 5 so if we
apply this formula we have this result
0.2 times 5 equals 1 ppm so we have the
MRL for soybean oil for pyraclostrobin
which is 1 ppm but this is not
always enough because as you see here in
the database
the pyraclostrobin has an F which
means that this pesticide is fat soluble
in the next video we will talk about the
other active ingredients that are not
fat soluble thank you for your attention
see you
