- Abstract
In this study, the vitamin B contents were analyzed in the edible portions of various shellfish (bivalves and snails). High vitamin B contents (30.5-53.3 μg/100 g wet weight) were detected in mussels, surf clams, bloody clams, and freshwater clams. However, scallops and abalone had extremely low vitamin B contents (0.1-1.1 μg/100 g wet weight) which was attributed to only the muscle portions being edible. These results suggest that high levels of vitamin B are accumulated in the viscera of shellfish. Vitamin B levels were also significantly higher in bivalves than in snails. The corrinoid compounds purified from all bivalves were identified as 'true' vitamin B using liquid chromatography-electrospray ionization/tandem mass spectrometry. In edible snails, abalone, and pond snails, however, both vitamin B and pseudovitamin B (an inactive corrinoid) were observed to be the major and minor corrinoid compounds, respectively. Based on these results, we conclude that the whole bodies of these edible bivalves are excellent sources of vitamin B for humans.
