The fructan control flours should be analysed in the same way as your samples, throughout the entire procedure. As the fructan control contains approx. 25% of fructan (the exact value is stated on the label) the extraction should be done as for samples containing 12-50% (w/w) fructan. To ensure the accuracy of the method.
