虽然鱼卵(或含卵卵巢)是具有高营养价值的海产品,并且被认为富含维生素(包括维生素B12),但是,维生素B12的详细性质在鱼卵产品中尚未完全阐明。样品经免疫亲和柱纯化后,用C18-反相高效液相色谱法测定维生素B12的含量。发现鲑鱼卵卵巢产品(sujiko)、鲑鱼卵产品(ikura)、干乌鱼卵产品(bottarga)和白色鲟鱼卵产品(鱼子酱)含有大量维生素B12(超过约15 µg/100 g湿重)。有趣的是,在青鳕鱼卵产品(tarako)和飞鱼鱼卵产品(tobiko)中测得每100克湿重的维生素B12含量很高。液相色谱-电喷雾离子化/串联质谱分析表明,维生素B12是主要的类可丽素在评估鱼籽产品检查,而没有非活性的类可丽素化合物被确定。这些结果表明,市售鱼卵产品可能是维生素B12的重要来源,可用作人类的膳食产品。
Although fish roes (or the egg-laden ovary) are seafood products with high nutritional value and are considered abundant in vitamins including vitamin B12, nevertheless, the detailed properties of vitamin B12have not been fully elucidated in fish roe products. Vitamin B12content was determined using C18-reversed-phase high-performance liquid chromatography after purification of samples from immunoaffinity columns. Salmon egg-laden ovary products (sujiko), salmon roe products (ikura), dried mullet roe products (bottarga), and white sturgeon roe products (caviar) were found to contain substantial levels of vitamin B12(more than approximately 15 µg/100 g wet weight). Interestingly, high levels of vitamin B12per 100 g wet weight have been measured in pollack roe products (tarako) and flying fish roe products (tobiko). Liquid chromatography–electrospray-ionization/tandem mass spectrometry analysis revealed that vitamin B12was the predominant corrinoid in the evaluated fish roe products examined, while no inactive corrinoid compounds were identified. These results suggest that commercially available fish roe products could be an important source of vitamin B12for use as a dietary product for humans.
