Abstract

|
|
|
In this study, the contents of water-soluble vitamins B1 (thiamin), B2 (riboflavin), B3 (niacin), and B12 (cyanocobalamin) in namuls (wild greens), such as salads and side dishes, consumed in Korea were quantified by high-performance liquid chromatography (HPLC) with UV and fluorescence detection. All samples were prepared with recipes used in Korea. All analyses were performed under the quality control of vitamin B1, B2, B3, and B12. The vitamin B1, B2, and B3 contents in namuls consumed in Korea were analyzed. The highest content of vitamin B1 was 3.018±0.016 mg/100 g in Putgochudoenjang- muchim. The highest contents of vitamin B2, B3, and B12 were 0.279±0.003 mg/100 g in Gul-muchim, 12.241± 0.040 mg/100 g in Chamchi-salad, and 8.133±0.371 μg/100 g in Pijogae-muchim, respectively. These results showed that animal-based ingredients in salads provided for good intake of vitamin B12. These results can be used as basic data for food composition tables and improvement of the national health of Koreans.
