Chapter 210 [209] Delicious Fisherman 60 (three more)
Afterwards, Xiao Yu popularized some health issues in this area for Yaya. Although the child was confused about bacteria and harmful substances, she didn't understand them, but she understood what she summed up, that is, You can't drink sea water directly, and you can't eat it even if it is boiled. In fact, Yaya doesn't like it either.

"Sister, the sea water is not good. It is bitter, salty and has an astringent taste. I can't tell what it feels like. It's terribly unpalatable, and the kimchi made with sea water is not as delicious as the one made with salt. All the aunts and aunts in the village say so."

"Of course it's not tasty. Do you think there is only salt in seawater? There are other things in it. Moreover, the salt boiled directly with seawater cannot be eaten directly, because there are too many impurities in it, and eating it is only harmful to people. There is no good in the bad."

"We can't see these substances with our eyes. After taking them for a while, they seem to be no big deal, but if we continue to eat them for a long time, many diseases will accumulate. You must say that for so long, no one has heard of them. You can get sick from eating sea water, right?"

Yaya opened her mouth, a little embarrassed: "It's true that I haven't heard of anyone getting any disease from eating sea water."

"That's because a person's life is too long. In the natural law of birth, old age, sickness and death, people eat whole grains, fly in the sky, run on the ground, swim in the sea, and eat everything. However, there are so many diseases, and there are many incurable diseases. What do you do? Are you sure it wasn't caused by eating seawater? Just like this plague, you only know that the disease was brought by rats, but you don't know what source of disease these rats passed on, right?"

Although Yaya is young, it is undeniable that Xiaoyu's words are very reasonable. For example, grandma's tuberculosis is caused by fever, but there is no reason, so how can there be fever?Mostly because there are so-called germs or viruses hidden around you that you can't see?

"Okay, don't be too nervous. I'll just say this, and you can remember it later. However, we are facing the sea and don't know how to make salt, so it's a bit unreasonable. Go, bring a few buckets of seawater over, today My sister will teach you how to make salt."

Yaya was so shocked that her eyeballs almost fell out: "Sister, I heard you right, do you know how to make salt?"

Xiao Yu proudly raised her chin, "What's so difficult about it? It's just a waste of firewood."

Although the salt she makes doesn't meet the salt standards of later generations, she thinks it's much better than the coarse salt here.

In ancient times, without the modern precision instruments of later generations to purify salt, add iodine, and add various nutritious substances, it is not easy to make white crystal fine salt.

As we all know, seawater is the "hometown" of salt. Seawater contains various salts, about 90 percent of which are sodium chloride, which is table salt.

In addition, it also contains magnesium chloride, magnesium sulfate, magnesium carbonate and other salts containing various elements such as potassium, iodine, sodium and bromine.

Magnesium chloride is the main component of the brine used to order tofu, and its taste is bitter. Therefore, seawater with a large proportion of salts tastes salty and bitter.

And what she has to do now is to use the most primitive method to extract salt from seawater, which is still edible salt, not bitter and salty salt.

The method sounds simple, you only need to pour seawater into an iron pot and boil it, and the white particles left after it dries are salt, but this is not done completely, because the salt extracted in this way is not pure enough and will still be bitter .

So when you watch those videos of drying salt, you will find that they will not completely evaporate the seawater and then add seawater, but leave a part of the seawater first, and only take a layer of salt crystals at the bottom, so that the taste will be better. Not too bitter.

In the same way, when we cook salt, we add sea water after half of it is boiled, and then continue to cook, and then pour out the sea water after half of it is boiled, so that the salt obtained will be better than boiled dry.

After listening to her talk about how to make salt, Yaya and the others had no choice but to scrape out the soup first, put it in a nearby pot, then add sea water to the pot, and boil the salt first.

The whole afternoon, the two of them didn't care about eating, they squatted in front of the stove, and kept adding firewood into it. I don't know how many times they added firewood and seawater. Finally, they boiled two large buckets of seawater and extracted about Three or four taels of salt.

——In this chapter, there are knowledge points about salt extraction, so I took the initiative to add [-] words to the number of words to make up for the encyclopedic knowledge.
