yes this is because FTU is measured at a pH of 5.5 in the method, while the phytase needs to work at lower pH levels. so any phytase which has a pH optimum at 2-4 will have a high activity but might have a lower FTU analysed at pH 5.5 compared to a phytase which has a pH optimum at around 5.5 but much lower activity at pH 2 to 4.

in our many studies involving numerous phytase products, it seems like the term FTU is totally meaningless. supposedly 500 FTU from phytase A should be equal to 500 FTU from phytase b but seldom is.

yes I have many time. it is not a bad product however the economics of it mostly ends up negative - meaning there is no or very little return on investment.
unless you want to make omega 3 meat or products - then it is a better choice than fish oil or linseed oil as the off-flavour is less.
