Method Reference:
AOAC 2011.06
Method Description:
A homogenized sample is weighed and internal standard and phosphate buffer are added. Amylase and protease enzymes are added to further break down the matrix for extraction of the folates. Conjugase is used to de-conjugate the polyglutamate forms of folates to mono-glutamates. The sample is centrifuged, filtered and cleaned using SPE. The folates are analyzed by UPLC-MS/MS. Folic acid is quantified. Isotopically labeled internal standards are used to control matrix to matrix variation.
