|
Biotin is an important vitamin functioning as coenzyme in several carboxylase-mediated metabolic reactions. Total 105 foods were selected as the target samples, of those 75 samples were highly and frequently consumed by Korean and the others were potently high biotin content foods. HPLC with the triple column system had been optimized and applied for the analysis of biotin in various food samples. The foods with the biotin concentration over 0.10 μg/g were 13 kinds of foods such as soybean (2.037 μg/g), soy milk (0.591 μg/g), pork liver (0.455 μg/ g), etc. The total daily biotin exposure per person via average and the 95th percentile food intake was 44.656 and 169.416 μg, respectively. The Korean staple food, rice contributed as fifth diet for biotin intake (3.433 μg/person/ day) following soybean (9.167 μg/person/day) > milk (6.018 μg/person/day) > soy milk (4.433 μg/person/day) > beer (4.428 μg/person/day).
