The VitaFast® Biotin test kit (product code P1003) is a microbiological method for the quantitative determination of total biotin (added and natural biotin) in food and pharmaceuticals. The microbiological test system complies with international standards.
- Vitamin B7 (biotin) is extracted from a homogenised sample and the extract is diluted. The diluted extract and the standards are applied to the wells of a microplate coated with Lactobacillus plantarum . Bacterial growth depends on the vitamin content of the sample or standard. Lactobacillus plantarum belongs to the lactic acid bacteria and has an absolute growth requirement for vitamin B7 (biotin).
- This organism is therefore ideal for the quantification of vitamin B7 (biotin) in food and food supplements. In general, 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.
- Certified by AOAC-RI 101001.
- The test system is very robust and suitable for routine analysis.
- The VitaFast® test kits share a uniform procedure across the whole product line.
