摘　　要：目的:检测部分常见食物中的维生素B_(12)(VB_(12))含量。方法:采用莱希曼氏乳酸杆菌ATCC 7830法测定5种菌菇、圈养母鸡蛋和散养母鸡蛋以及16种发酵豆制品中VB_(12)的含量。结果:5种菌类中均含有一定含量的VB_(12),其中香菇含量最高,含量为1.1μg/kg,猴头菇、白蘑菇和金针菇的VB_(12)含量分别为0.43,0.22,0.13μg/kg,而银耳中VB_(12)含量最低,为0.12μg/kg。圈养鸡蛋与散养鸡蛋的VB_(12)含量分别为0.35μg/kg和0.44μg/kg。16种发酵豆制品中的VB_(12)含量均低于鸡蛋,其中自制豆豉含量最高(2.15μg/kg),生抽酱油最低(0.11μg/kg)。结论:蘑菇和鸡蛋是所有限制肉类摄入人群的VB_(12)的最佳来源。Objective:The aim of this study was to detect the content of vitamin B_(12)(VB_(12))in some common non meat foods.Methods:The content of VB_(12)in five kinds of mushroom,caged and free-range hen eggs,and 16 kinds of fermented soybean products were determined by the method of Lactobacillus leishmanii ATCC 7830.Results:All five kinds of fungi contain a certain amount of VB_(12),of which the content of Lentinus edodes was the highest,it was 1.1μg/kg.The VB_(12)contents of Hericium erinaceus,Agaricus bisporus and Flammulina velutipes were 0.43,0.22μg/kg and 0.13μg/kg,respectively,while the Tremella fuciformis had the lowest content at 0.12μg/kg.The VB_(12)content of cage eggs and free-range eggs was 0.35μg/kg and 0.44μg/kg,respectively.The VB_(12)content of all fermented soybean products was lower than that of eggs.Homemade douche contains the highest concentration of VB_(12)(2.15μg/kg)and the lowest soy sauce(0.11μg/kg).Conclusion:Mushrooms and eggs are the best sources of VB_(12)for all meat restricted populations.
