Product detail

1. Intended use

The folic acid test kit is a microbiological method for the quantitative determination of total folic acid (naturally occurring and added folic acid) present in food, animal feed and pharmaceutical products. The microbiological test system complies with international standards.

2. General information

- Folic acid is extracted from a homogenised sample and the extract is diluted. The diluted extract and the standards are applied to the wells of a microtitre plate coated with Lactobacillus rhamnosus. Bacterial growth depends on the vitamin content of the sample or standard.

- Lactobacillus rhamnosus belongs to the lactic acid bacteria and has an absolute growth requirement for the vitamin folic acid. This organism is therefore ideal for quantifying folic acid in food and food supplements.

- As a group, lactic acid bacteria are good candidates for vitamin analysis because of their genetic stability (resistance to mutation), simple metabolic requirements, ease of maintenance and general safety as a non-pathogenic organism.

3. Benefits of using the folic acid test kit for food

- Certified by AOAC-PTM 100903.
