This standard BS EN 14131:2003 Foodstuffs. Determination of folate by microbiological assay is classified in these ICS categories:
07.100.30 Food microbiology
67.050 General methods of tests and analysis for food products
This European Standard specifies a microbiological method for the determination of the total folate content of foodstuffs by turbidimetric detection of the growth of the microorganism Lactobacillus casei, subsp. rhamnosus (ATCC 7469). The method allows for the determination of folates in foodstuffs, including naturally occurring folates and added folic acid (pteroylglutamic acid).
