核黄素富含于各种动物性食品中,一般米面蔬菜含量甚微。部队平战时,假如由于某种原因,不能得到足够的动物性食品时,寻求代用品以补充核黄素,实属必要。陈文为、除以师等均曾用生物合成的方法在多种谷物上培养核黄素。但他们所用的培养基需用各种化学药品配制,一般不易得到。本实验试用做豆腐的副产品为原料生产核黄素,方法比较简便,部队容易做到;豆渣中核黄素含量,经测定,本法与一般法所得结果基本一次。 Riboflavin is rich in various animal foods, the general rice content is minimal. During the peacetime wars, if for some reason, enough animal food can not be obtained, it is necessary to seek substitutes for the supplement of riboflavin. Chen Wen-wei, division by division, have used biosynthetic methods in a variety of cereals cultured riboflavin. However, the medium they use need to use a variety of chemical preparation, generally not easy to get. In this experiment, the byproduct of tofu was used as the raw material to produce riboflavin. The method is simple and easy for the troops to do. The content of riboflavin in bean dregs was determined. The results of this law and the general law are basically the same.
