This is a microbiological method employing the organism Lactobacillus plantarum to determine calcium pantothenate or other free forms of pantothenic acid in vitamin concentrates and food products.
The ground, homogenized sample is dissolved or dispersed in double distilled water. The pH is adjusted to 5.65 and the mixture is autoclaved at 121 – 123°C to extract pantothenate or other free forms of pantothenic acid. The extract is diluted with a basal medium containing all required growth nutrients for Lactobacillus plantarum except pantothenate. The mixture is then innoculated with the microorganism and incubated at 37°C for 22 hours. The growth response of the microorganism is compared quantitatively to that of known standard solutions of calcium pantothenate. The method is semi-automated, utilizing an Automated Pipettor System and an Automated Plate Reader System.
