Based on the results in table 2, it can be concluded that just 7 of the 19 samples contain fructan at a
level of more than 0.04 % before reconstitution of the powdered samples. The fructan containing
samples are marked in yellow.
The purity of the applied fructan standards in this study is established by determining the fructan
content in these standards with the AOAC 997.08 method. The analytical results are very well in
agreement with the analytical results obtained with the presently submitted SPIFAN method as can be
seen in table 3.
