Single Lab Validation of a Method for the
Determination of β-Galactooligosaccharides in
Infant Formula & Adult Nutritionals
Objective
Question
Determine if the performance of a method to determine β‐
galactooligosaccharides (GOS) in infant formula and adult
nutritionals meets the requirements set by the AOAC‐SPIFAN
working group

Summary
Answer
The method developed meets most of the standard method
performance requirements that can be tested in a single lab.
Unfortunately the trueness of the method is, in general, slightly
below the target of 90‐110%, but the method is currently the best
solution available for the determination of GOS in lactose‐
containing matrices.
