When you bowing in the toilet, the odor you smell is skatole, you should keep in mind that skatole is the source of the odor in the feces …” There is nothing incorrect with what the instructor claimed, however aside from that, we still have a lot to contribute |

You have to recognize that the feces of creatures (Keke, do not ask me why I show up below, what can we do, we can’t help |) is usually the location where we were birthed, we were birthed here and also died swiftly in individuals’s assumptions |

Certainly, some people were fortunate adequate to be birthed in coal tar, after humans removed, refined, and also thinned down in big amounts, so their hearts were sublimated, and also a fragrance similar to jasmine offered us a brand-new “smell life definition” |


This way, as one of the most frequently used fixative for humans, we are commonly made use of in the fragrance market, not only jasmine scent, yet also citrus, gardenia, lotus, narcissus, brandy as well as various other scents have our engagement.

Naturally, our contributions don’t stop there. There is a saying in humans that “food is the paramount necessity of individuals”. The initiatives we have made in the food industry are enough to make human beings confront our presence: allow’s speak about the smelly tofu you are most knowledgeable about. Recently, it can be claimed that there is one more “smelly wave”! When you walk around the night market, you don’t also require to look, you can discover it with your eyes shut as well as complying with the scent.

Mentioning the scent, the compound hydrogen sulfide was produced during the fermentation process of the tofu, as well as the indole molecules created by the fermentation of the brine also enhanced the problem of biochemical protection. In the end, the molecules continued to move, and the smell effectively inhabited the high ground as well as filled the air. Your human nasal flows.

As for why odiferous tofu preferences so tasty? Obviously, the healthy protein of fermented smelly tofu is hydrolyzed right into polypeptides, amino acids, specifically glutamic acid. You need to know that glutamic acid is a crucial element of hen essence, so stinky tofu smells odiferous, yet it tastes scrumptious |

Allow’s speak about the preferred snail powder, tsk tsk|Isn’t our distinct sour odor distinct to the favor of many youths? As a matter of fact, snail powder additionally has us!

The smell mainly originates from the fermented sour bamboo fires. During the pickling process, the sour bamboo shoots need the simultaneous activity of cardio as well as anaerobic bacteria. The sugars and also proteins in the bamboo shoots are fermented and finally exchanged numerous amino acids, our indole A family members was likewise birthed from this. On top of that, natural acids, aldehydes, alcohols and various other materials also contributed their strength. Therefore, the snail noodles ended up being smelly as well as enchanting|what makes people intend to quit is durian, which is different from the above two. Compared to various other sort of ingredients, durian has its own “scent”|After the durian is ripe, the thionine in the pulp will boost, and afterwards converted into mercaptans as well as derivatives, which is also the key to the smell of durian.

It is additionally amazing that some people believe the fragrance is solid, some people think that the fruit scents like pet cat feces, and also some people question: “Thionine is damaging to wellness as well as can not be consumed!” This is bullying “lotus”. Although durian is stinky, But you need to take a lot of it to be infected |

There are still several other foods committed to the Indole family members|Soybeans are saturated, steamed, dried, and then fermented with Natto germs for 20 hrs, and the healthy and balanced natto is born; it is rumored that canned herring can stink to fatality; Preserved eggs seasoned with soda ash, black tea, and quicklime; outsiders are frightened by the scent, and also Beijingers like that mouthful of soybean juice, etc, all of which are the darkness of our indole family members |
