The results obtained by a radiometric assay of folate in fortified gruel and porridge, using a commercially available radioassay kit, were compared with those obtained by a standard microbiological assay with Lactobacillus casei. A lower level of folate was found with the radiometric assay. Comparison of the results obtained with the two methods gave a correlation coefficient of 0.991 when the analysis was performed on samples extracted at the same time. A lower correlation coefficient was obtained between the result if the extractions were carried out on different occasions. The radiometric assay is a acceptable method for the routine determination of folate in fortified gruel and porridge.
