谷氨酸钠制造工艺流程

谷氨酸钠制造工艺流程
英文回答：
The manufacturing process of sodium glutamate involves several key steps. The first step is the fermentation of a carbohydrate source, such as molasses, with the bacteria Corynebacterium glutamicum. During the fermentation process, the bacteria produce glutamic acid, which is the precursor
to sodium glutamate.
After the fermentation is complete, the next step is to isolate and purify the glutamic acid. This is typically
done through a process of filtration and chemical precipitation to remove impurities and concentrate the glutamic acid.
Once the glutamic acid is purified, it is then neutralized with sodium hydroxide to form sodium glutamate. This reaction results in the formation of sodium glutamate crystals, which can be further processed and dried to
obtain the final product.
The final step in the manufacturing process is to package the sodium glutamate for distribution and sale to various industries, such as food processing and pharmaceuticals.

谷氨酸钠的制造过程涉及几个关键步骤。

第一步是利用细菌谷
氨酸棒状杆菌对碳水化合物源（如糖蜜）进行发酵。

在发酵过程中，细菌产生谷氨酸，这是谷氨酸钠的前体物质。

发酵完成后，下一步是分离和纯化谷氨酸。

通常通过过滤和化
学沉淀的过程来去除杂质并浓缩谷氨酸。

一旦谷氨酸被纯化，接下来就是用氢氧化钠中和谷氨酸，形成
谷氨酸钠。

这个反应会产生谷氨酸钠晶体，可以进一步加工和干燥，得到最终产品。

制造过程的最后一步是将谷氨酸钠包装好，以便分销和销售给
食品加工和制药等各个行业。
