Now the crayfish epidemic is a worldwide problem: Europe, Asia, the Americas, Africa are all facing this problem。。。。。。 For example, Dongying, who brought crayfish to the Han Kingdom back then, is now flooded with crayfish, and the original twenty crayfish have produced countless offspring. What sewer drains are full of crayfish, and in serious places the sewers are clogged with crayfish.

That's why Yang Meng said to Imai Monroe: Crayfish are their nightmare.

Can the crayfish grown up in that environment be eaten? Naturally, no, the crayfish that come from the Dongying people's table are not eaten, but crushed and used as waste for farming. In fact, this is also the case in many parts of Europe and the Americas.

This gives people a misconception: they think that foreigners don't eat crayfish.

In fact, many countries have the habit of eating crayfish. Even Han is not a major market for crayfish consumption!

For example, the Americas, the Caribbean, Oceania, Africa, and Europe all have the tradition and history of cultivating edible crayfish, and for a long time, the country with the most crayfish consumption in the world is not Han but Stars and Stripes. In 1990, Louisiana alone produced 90% of the world's crayfish, 70% of which was eaten by the locals themselves.

Every year in April and May, several crayfish-producing states, including California, Florida, and Louisiana, hold the 'Crayfish Carnival', when countless people flock to these places to set up a large pot and cook tons of crayfish with curry, cinnamon, peppers, lemon juice and so on for human consumption!

In fact, a considerable part of the crayfish in the Han Kingdom were exported! Eighty percent of them were exported to European and American countries, and almost all of the rest were given to Dongying------ who especially liked to eat them!

At this time, many people are puzzled: why do foreigners import crayfish from Han when crayfish are flooded?

First of all, not all places on the foreigner's side are flooded with crayfish, only local areas, and in addition, it is cheaper to import crayfish from Han than to catch them yourself.

And foreigners are 'stupid'.

This is really not a joke, this is going to say that Chinese food is amazing!

In fact, the way to cook crayfish in the Stars and Spangled Country is also very good, usually seasoned with onions and lemons, and then cooked with corn sausages and the like, which is also very good. But the crayfish thing must be spicy, if it's not spicy, it won't be addictive, right?

For a long time, it was boiled or steamed and dipped in sauce, and it was not so popular. The price is also very cheap. It's just a filling-up gadget.

However, the foodies on the Qianjiang side of Hubei Province have completely changed the survival status of crayfish.

Since the 80s of the last century, Qianjiang people have begun to fry crayfish, and a 'braised crayfish' has developed the delicacy of crayfish. Later, when the crayfish entered Sichuan, people found that the spicy taste was a good way to cover up the earthy smell of crayfish, so the crayfish began to become popular all over the country. There are also endless ways to cook crayfish, what garlic crayfish, beer crayfish, thirteen spiced crayfish, beer crayfish。。。。。。 It satisfies the tastes of different people.

The Qianjiang people have developed the cultivation method of 'shrimp and rice continuous cropping', and a large number of crayfish are cultivated

。 At present, more than 75% of crayfish are farmed in rice fields, and Hubei Province occupies half of the country's crayfish farming. Now many places are famous for breeding crayfish, such as Xuyi (xu yi), if it is not crayfish, many people may not know how to write these two words!

This has also led to the popularity of crayfish in the Han Kingdom, which has become one of the most popular delicacies in the Han Kingdom.

There is another reason why crayfish are not so popular in foreign countries: many people think that crayfish live in a poor environment and live in sewage, and they look weird and scary, so many people refuse to eat crayfish. There are fewer people, and there are fewer people who eat them, so how to solve the problem of crayfish flooding?

While disgusted, I couldn't refuse the deliciousness of crayfish, which also made foreigners quite entangled.

But people also have a way: the crayfish they imported from the Han Kingdom are peeled off the shell and only the shrimp meat------ which is convenient for cooking. And most of the crayfish exported by Han are of this type.

Looking at the white and tender crayfish meat, it is natural to forget their original appearance, and quickly buy them home and eat them ------ standard 'mouth and body integrity'.

The same goes for Dongying. People claim to be 'the country closest to the West in Asia,' and they love to eat crayfish or not? They also love to eat crayfish! Every year, they import a large amount of crayfish meat from Han China, but on the other hand, they allow crayfish to flood in their own country.

And there is another reason for importing from Han: hygiene.

Many people think that crayfish are very dirty because they grew up in stinky gutters, including Han Guo, where there have also been food safety problems caused by eating crayfish such as 'washing shrimp powder'. But after so many years of governance, the crayfish that everyone eats on the table now are artificially farmed. And in order to make the crayfish white and chubby more popular, those farmers are heartbroken. It is also necessary to feed a variety of animal and plant feeds regularly, and wheat bran, soybean cakes, insect larvae, etc. are very expensive. Nowadays, as long as the farmed lobster is 'pinched and tailed', it can be eaten boldly with confidence.

But the popularity of crayfish in Han has also brought another problem: environmental pollution.

Crayfish meat is delicious, but how to deal with crayfish shells is a trouble. Especially in those places where crayfish meat is exported, what is done with the crayfish shells there?

What are the Han people best at? Turn waste into treasure!

What is the most important ingredient in crayfish shells? It is 'chitosan', although this thing is very abundant in nature, but lobster shells contain the most content. The biggest feature of this chitosan is that it is non-toxic and easy to degrade. So in the past, crayfish shells were used to make fertilizer and the like, but now, through various scientific and technological processing, the discarded crayfish shells have been turned into glucosamine hydrochloride, and the market price of this thing is more than 100,000 yuan a ton! Various kinds of lobster shells have been processed and produced as many as 14 kinds of high value-added products. The economic profit brought by lobster shell in the entire lobster industry chain is as high as 55%, even if the price of crayfish has plummeted due to the epidemic, but relying on various scientific and technological processing of shrimp shells, the lobster industry chain can still run!

Yang Meng sighed and said, "You said that this person has brains, why is the gap so big?"

"Why do you say that?" asked Long Xixiang.

Yang Meng sighed: "You said that we have all eaten crayfish, but have you ever thought about it?

Everyone was stunned, yes, this crayfish is often eaten, but who has thought about this problem?

Yang Meng continued: "A group of college students thought of this, they thought that the high temperature resistance of crayfish shells was quite good through this phenomenon, and then began to experiment, and finally obtained an additive, which can be fully mixed in the matrix asphalt to improve the performance of asphalt, which can effectively improve the high temperature performance of asphalt. If this thing is used in the south for pavement construction, it can not only improve the performance of traditional pavement materials, but also reduce the pollution of biological waste to the environment. That's how they combined biology and food science and technology with infrastructure engineering! Why do you think the gap between this person and man is so big? Why can't we think of such a thing? I understand now that the more people learn about this thing, the more ignorant they feel. The more bullshit is not less than half a bottle, the more it is a troll keyboard warrior. ”

After hearing this, Long Xixiang thought for a while and said, "Then how did Jing Jing operate this matter?"

Yang Meng said: "She has bought the patent for this product and is ready to operate it." ”

After hearing this, Long Xixiang said: "This thing is not easy to do." First of all, if it is related to urban construction, it must be linked to state-owned enterprises, even if the product is good, this increased cost will be difficult to do. Mengmeng, you haven't dealt with the relevant personnel of state-owned enterprises, you don't know. I used to deal with them a lot when I was in the Long Group. The procedures are cumbersome, and the layers of approval are even counted, as long as it is related to money, it means endless trouble, and if you want to supply it there, it is all kinds of squeezing costs。。。。。。 If Jingjing only has patents, it will first invest in relevant equipment, and then it will take time and cost to market the product------ which will take time and cost. The return on investment is slow, and unless she can enter the capital market to raise funds, it is difficult to see profits. ”

Yang Meng turned his head and asked Zete with a smile: "Zete, what do you think of this?"

Zete said: "If you want to do it, you can do it! Jingjing has been studying there for so many years, and she also wants to prove herself." She can see the potential here is already very good, and your vision is still a little limited, if this high temperature additive can really improve the performance of asphalt pavement at high temperatures, it is a very good product, now all countries in the world, including our country, have high temperature sunning pavement situation, quietly want to do it. Now the new track must use asphalt pavement, and the advanced track needs to be laid with three layers of asphalt: the lowest layer is the coarse asphalt concrete bearing capacity after 10 centimeters, and the flatness is less than 8 millimeters; the middle layer is the 4 centimeter medium-grained asphalt concrete adhesive layer, and the flatness is less than 5 millimeters; the upper layer uses the four-centimeter modified asphalt mixture as the surface wear layer, and the flatness is less than two millimeters. If only the top layer of the modified asphalt mixture is used quietly, it will not cost much. You can also support your sister and let everyone see the effects of this asphalt additive. If it proves that the product works well, this is a big market in the world! Meng Meng, if it really comes to that day, Jing Jing will become a little rich woman!"

Long Xixiang pursed his lips after hearing this: "The vision of seven doctorates is different." Zete, I'm jealous of you!"
