The Vitamin B1 or Thiamin test kit, VitaFast® Vitamin B1 (Thiamin), is a microbiological method for the quantification of total vitamin B1 (added and naturally occurring vitamin B1) in food, animal feed and pharmaceutical products. The microbiological test system complies with international standards.
- Vitamin B1 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 fermentum. Bacterial growth depends on the vitamin content of the sample or standard.
- Lactobacillus fermentum belongs to the lactic acid bacteria and has an absolute growth requirement for vitamin B1. This organism is therefore ideal for the quantification of thiamin 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, easy maintenance and general safety as a non-pathogenic organism.
- The test system is very robust and suitable for routine analysis.
- The VitaFast® test kits have a uniform procedure across the whole product line.
