- Folate content in eggs from three different breeds of hens fed with three different feeds, one organic and two conventional, was compared using a simplified microbiological assay. Retention of folate when boiling the eggs was also studied. Folate content in eggs did not differ significantly due to the breed of hen or the feed used. The loss of folate when boiling the eggs was 9%. The results from the microbiological assay were confirmed by LC/MS. According to this study, 1 egg (60 g) provides 40-50 mu g of folate. This corresponds to 13-17% of the recommended daily intake, 300 mu g for adults in the Nordic Nutrition Recommendations. The folate forms found in egg yolk with LC/MS were 5-methyl-tetrahydrofolate and 10-formyl-folic acid, whereas no folates were found in egg white. In this study, no polyglutamate folate forms could be detected in eggs.
