Chapter 68 (1/2)

”What? Do you think this salt mountain can provide us with a lot of edible salt? It's impossible Li Lei stares at the stone bear and says, ”guardian, we all know that this hill is a salt mountain, but the salt in this salt mountain can't be eaten at all. If you eat it, you will die.”

The big foot nodded and said: ”yes, guardian, the leader is right. Our ancestors discovered this salt mountain as early as 200 years ago when they came here. Unfortunately, the salt produced in this salt mountain is not edible at all. The salt produced in this salt mountain is not only bitter, but also purple after eating. If you eat too much, you will die! Many of our ancestors died of eating too much salt in this salt mountain. Since then, our gaoshu tribe and all the surrounding tribes have stopped eating the salt here. ”

Hongyun, gaoniu and other tribal leaders also nodded. It is obvious that they all know about this salt mountain.

Stone bear helplessly shook his head, it is really no culture, really terrible.

In later generations, everyone knows that salt, whether it's sea salt or land salt, can't be eaten directly.

The sea salt directly dried out can't be eaten directly. It's bitter. There are a lot of impurities in it. It needs another cooking process to eat. Therefore, most of the sea salt directly dried in the air in later generations was used to make industrial salt.

The same is true for the salt produced on land. Even the best well salt has to be injected into brine first, and then pumped up. After a series of processes such as filtration and evaporation, edible salt can be formed.

In a word, as long as it's natural salt, it can't be eaten directly. The impurities in it are not only bitter but also astringent. The most important thing is that it can kill people.

Natural salt contains a lot of nitrate, phosphorus, potassium and other impurities, which can be fatal if you eat too much.

Nitrate is used to reduce blood pressure. If you eat too much, people's blood pressure will drop to a certain extent. Even the stone bear can't stand it.

As for phosphorus, that kind of thing can't be said to be as toxic as cyanide, and it's not much different. Moreover, people will be purple after eating it.

These impurities are not needed by the human body. Later generations have heard of calcium and iron supplements, but have you heard of phosphorus and nitrate supplements?

That's the reason.

Just like the little salt mountain, before the gaoshu tribe mastered the processing technology of crushing, dissolving, filtering and parsing, it was a salt mountain that could be seen and eaten, no different from chicken ribs.

But once we can master these processing technologies, this salt mountain will become a treasure mountain immediately.

In fact, in this era, even the white people in Europe, few people can master this kind of processing technology. Even if they have mastered it, it is the most fundamental secret.

People point to selling salt to make money. Who would be so stupid as to tell their secret?

But stone bear, who came from the era of information explosion, naturally knew this kind of processing technology.
