Effectivity factor versus steepness
Effectivity factor = N20/safa level
Steepness factor = N20/N35

If mixtures of these components are prepared with Rapeseed oil to get N20=15
then the safa level will vary between 30 and 45, but also N35 will vary between
0 and 8.
From these examples can be seen that a high effectivity with high steepness is
difficult. For each application the optimal fat blend, consisting of various
components, should be defined by taking into account health aspects (lowest
possible safa), taste keep ability (oxidation) and functionality in application.
