4. Conclusion.
The method used for this SLV meets the requirements as described in the AOAC
SMPR 2014.002 for fructans in Infant Formula and Adult/pediatric Nutritional Formula
in which fructan is present in a concentration ranging from 0.03 to 0.5 g/100g
reconstituted final product.
The
precision
as done during the SLV meets the repeatability as proposed by the
workgroup, being ≤6%.
The
accuracy
was performed by spiking the Test Materials kit samples by 3 different
pure fructan products of different origin (sugar and chicory) and DP range. The
spiking/recovery is ranging from 96.9 to 107.1% with a mean of 100.3%, which is very
well meeting the proposed requirement of 90-110%. The very low concentrations
(spike level 0.05) are included during this spiking test and even these meet the
proposed range.
