Stinky tofu, like durian, is a very strange existence to me. I can't figure out why stinky tofu can be so smelly, but it tastes particularly delicious and fragrant. In fact, not only the authentic stinky tofu in Changsha smells bad, but the stinky tofu in all parts of the country smells bad, but the degree of odor is different.

stinky tofu smells bad because stinky tofu is a fermented food. During the fermentation of bean products, amine substances such as methylamine, putrescine, tryptamine and hydrogen sulfide are produced. And these substances have a special smell and strong volatility, so they are often not close to stinky tofu, and they can already smell this smell in the distance.

Then why does stinky tofu taste so delicious? It is because the protein in tofu is decomposed into amino acids in the fermentation process, and the amino acids have a delicious taste, so stinky tofu is not bad at all.

However, although stinky tofu is delicious, you should not eat more, because the production process of stinky tofu is still unacceptable to most people. In the fermentation process, some bad substances are easily produced, and at the same time, it may be contaminated by bacteria. So for the sake of health, it is better to eat less stinky tofu.

how to identify inferior stinky tofu? It can be judged by the method of "one look, two sniffs and three breaks": first, look at whether the water in which stinky tofu is put is as black as ink, if it is too black, it is abnormal; Secondly, smell whether the surface of tofu tastes pungent, and if pungent, add ammonia water; In addition, take a look at the tofu and see if it is white inside. If the color difference is large, the quality will not pass.
