Why does stinky tofu smell and taste delicious?

Stinky tofu is one of the special snacks of the Han nationality in China. It is made of high-quality soybeans with high protein as raw materials through many processes, such as soaking beans, grinding pulp, filtering pulp, brine, pre fermentation, pickling, soup filling, post fermentation and so on. It smells smelly and tastes delicious. Some people stay away from it, while others regard it as a hobby.

[cause of odor]

In the process of fermentation and post fermentation, the protein contained in stinky tofu is decomposed under the action of protease, and the thioamino acids contained are fully hydrolyzed to produce a compound called hydrogen sulfide (H2S), which has a pungent odor. That's why stinky tofu stinks.

[reason for fragrance]

After the protein contained in stinky tofu is decomposed, it produces amino acids, which have a delicious taste, so it "tastes delicious".
