AN155: Determination of Trans-Galactooligosaccharides in Foods by AOAC Method 2001.02

Instrument Type: IC

In AOAC Method 2001.02, a buffered extract of the sample containing TGOS is treated with an enzyme, β-galactosidase, that hydrolyzes TGOS to galactose and glucose. Galactose and other sugars are separated on a CarboPacTM PA1 column and detected by pulsed amperometric detection (PAD).
