When measuring fructan in starch containing samples, i.e. maize, is there a possibility of incomplete starch hydrolysis in step B of the Fructan Assay (K-FRUC) ?
From our experience, the level of beta-amylase/pullulanase etc. added is more than adequate to completely hydrolyse any starch likely to be present. How...

What is a typical %RSD (or %CV) value for the Fructan Assay Kit (K-FRUC)?
With all our kits we can obtain approx. 5% CV in interlaboratory studies. In-house these values are closer to 3%. Product Page (K-FRUC)

What is the factor value (F) of 54.5 used in the calculation of the Fructan Assay Kit (K-FRUC) - does it change depending on the fructose content?
The value of 54.5 is the actual amount of fructose standard used. This amount of fructose will give a certain colour in the PAHBAH assay. Thus; F = fac...

Is it possible to buy Fructanase separate from the Fructan Assay Kit (K-FRUC)?
Yes. The best enzyme to use for analytical purposes is exo-Inulinase (E-EXOIAN). Product Page (K-FRUC)

Can the sucrase used in the Fructan Assay Kit (K-FRUC) be used to analyse sucrose in extracts of chicory roots?
Yes, the sugar enzyme can be used to measure sucrose. The enzyme is an alpha-glucosidase, so it will also hydrolyse maltose if this is present. P...
