高中课本只介绍了淀粉是食物的重要成分,也是重要的工业原料,可用以制造葡萄糖和酒精。另介绍味精可由水解蛋白质制取。其实,如今蛋白质不再是制取味精的主要原料,现在大宗的味精是以淀粉为原料,采用发酵法制得的。就是没有介绍淀粉与味精之间的联系。教学时不妨给学生补充一点这方面的知识。下文对发酵法生产味精作了简单的介绍。 High school textbooks only describe starch as an important ingredient in food and as an important industrial raw material for the manufacture of glucose and alcohol. Another introduction of MSG can be made from hydrolyzed protein. In fact, the protein is no longer the main raw material for MSG production, and now the bulk of MSG is based on starch as raw material, the fermentation method. Is not to introduce the relationship between starch and MSG. When teaching may wish to add a little student knowledge in this area. The following article on the production of MSG fermentation made a brief introduction.
