| h English (en) | === Methods for the analysis of vitamin B<sub>12</sub> in food === Several methods have been used to determine the vitamin B<sub>12</sub> content in foods including microbiological assays, chemiluminescence assays, polarographic, spectrophotometric and high-performance liquid chromatography processes. The microbiological assay has been the most commonly used assay technique for foods, utilizing certain vitamin B<sub>12</sub>-requiring microorganisms, such as [[Lactobacillus delbrueckii subsp. lactis|''Lactobacillus delbrueckii'' subsp. ''lactis'']] ATCC7830. However, it is no longer the reference method due to the high measurement uncertainty of vitamin B<sub>12</sub>. |

''lactis'']] ATCC7830である。しかし、ビタミンB<sub>12</sub>の測定の不確かさが高いため、もはや基準法ではない。 |
