"Dad, I miss you so much."

He jumped and Nan Ruoqiu rushed into Nan Yi's arms.

"I don't miss you, a damn girl movie. In three years, I spent 72 million US dollars. I'll explain to me how this money was spent."

Nan Ruoyan pouted, "Hmph, dad treats me as a fool again, how could you not know?"

"Dad really doesn't know. I only care whether you are safe or not. Although I can know the others, I have never read the report. You little girl's movies have grown up and need some privacy."

Nan Yi pinched Nan Ruoyan's nose and then put the person on the ground, "It's turned into a little fat pig, Dad can't hold you."

"No, Dad, I have a standard figure."

Nan Ruoyan stood around and showed off his figure.

"Okay, standard, but the skin has turned into wheat color and looks healthy, but..." Nan Yi thought for a while and said, "You have become ugly."

Nan Ruoyan said arrogantly: "It's not ugly. I believe this skin color will soon trigger a trend."

"Okay, maybe what you said makes sense."

Nan Yi remembered that it seemed that Japan and South Korea had indeed been dressed in a hot black girl, and wheat-colored skin was indeed popular with women.

"Ruo, you should talk to Wuwei first and show him what you see and hear. He is too young to say what he shouldn't say."

"I know."

Nan Ruoyan responded and walked to the side of Nan Wuwei. The brother and brother said a few intimately, and then Nan Ruoyan took Nan Wuwei to the pavilion.

After handing Nam Wuwei to Nan Ruoyu, Nan Yi ran to the backyard to take a bath to relieve his fatigue. After he was exhausted, Nan Yi read the report he brought back from the Hokkaido Dairy Ranch.

Shennong South Grain has always been a combination of planting, breeding, research and production, and research has always been placed in a very important position. In addition to the Fengsheng Research Institute system, each breeding base has its own primary researchers. These researchers must not only provide data and observation reports to the Fengsheng Research Group, but also be responsible for the implementation and implementation of research results.

As the global annual consumption of milk is moving towards the 200 million tons mark, it has always been a focus of Shennong South Grain and an important topic in the research of Shengzhi.

This topic may be divided into three main research directions: sugar removal, preservation, and artificial synthesis.

Mammalian milk contains an ingredient "lactose". This substance is one of the main sources of energy for the growth and development of mammalian pups. It provides heat energy and is also the driving force for the development and activities of organs, nerves, limbs, muscles, etc.

For humans, "lactose" can also maintain the balance of water in children's bodies and provide galactose related to the composition of the brain and important organs, which is very important for children's intellectual development.

Lactose is also used in the small intestine by beneficial bacteria such as Lactobacillus, and produces lactic acid. Lactic acid has a regulatory and protective effect on the gastrointestinal and intestinal intestinal intestinal ulcers, and can also inhibit the growth of intestinal spoilage bacteria and reduce the chance of infants suffering from illness.

Lactate can also reduce the intestinal pH value. Under the action of acid, it can promote the absorption of nutrients such as calcium, iron, and zinc. It can also stimulate intestinal peristalsis, clean up the intestines, and prevent infants from being constipated and getting angry.

In short, lactose is a nutrient that infants and young children need to absorb, and this nutrient is contained in breast milk and milk.

However, as infants and young children are weaned, the lactase activity in the body will decrease with age, which will eventually lead to "lactose intolerance".

Milk is a fresh product and will deteriorate for a few hours at room temperature. Preservation of milk is a problem that has plagued humans for thousands of years.

According to archaeology of historians, who may not be reliable, humans had already lowered lactose by making cheese ten thousand years ago, but for a long time before the modern scientific revolution, humans did not know how to keep milk fresh.

Preservation can be divided into two steps - sterilization and preservation.

Milk can provide almost all the proteins that humans need. This is a good thing. Only for Milk, a thousand-mile horse, there are many men who can find it and are willing to support it, including calves, humans, and various bacteria.

In order to solve the bacteria in milk, humans have used various methods, such as putting frogs into milk. As long as you soak the frog in milk, the bacteria in the milk will be reduced a lot.

It is hard to know when this method was invented, but why this method was effective was studied by people a hundred years ago - it turned out that the mucus on frogs has a bactericidal effect.

Anyway, year after year, various sterilization methods emerge one after another, but no matter what the method is, it is better to cook milk before drinking it. However, in the eyes of people at that time, this was not a solution.

Raw milk and cooked milk can be said to be two different things. In the mouths of people who were used to drinking raw milk at that time, cooked milk was just shit.

This cognition has not been changed until the pasteurization method is studied, because people find that after sterilization, the milk becomes tasteless and not delicious. This is a more elegant statement when facing other people's questions. In fact, their real answer is still "shit".

It was not until nearly fifty years after the pasteurization method was invented that more and more people recognized Pasteurization, and it spread from knowledgeable people to prestigious people. Until people qualified to legislate legislation wrote on paper that people were gradually forced to accept innovation in the taste of milk.

In fact, many people still don’t think so. After understanding how pasteurization is done, some people muttered: “What is Pasteurization or Pasteurization? Isn’t it just boiling or high temperature? My ancestors eight hundred generations ago knew that this was done. Guess why I didn’t learn to do it?”

Regardless of whether people recognize it or not, the sterilization problem of milk has been solved because of Pasteurization.

However, pasteurized milk still cannot be stored for long. It usually deteriorates after two days at room temperature. The problem of preservation is considered to be the first half of the step, and the next half of the step is to continue.

Regarding preservation, in fact, people have come up with various methods since early on, such as storing ice in the ice cellar, using stone slabs to keep fresh, and using deep wells to keep fresh. Arabs also use pots and sand to make pots and medium pots [zeer pots].

At first glance, all preservation methods are inseparable from "low temperature". The unified idea of ​​aspiring to solve the preservation problem is how to obtain or create a low temperature.

The solution is so strange. Some people say they want to go to the North and South Poles to transport large quantities of ice cubes, and some people say they connect pipes to the snow-capped mountains in the Alps to connect cold air to thousands of households. Not to mention, this idea is very interesting. Later, some people imitate it, but the solution is not cooling but heating.

Later, refrigerators were invented, cold chain technology and transportation became developed, allowing people in cities to drink fresh milk from the countryside.

By the end of the 1950s, the wave of globalization swept, and the Osaka people who became rich first shouted not to drink Hokkaido's milk, they wanted to drink Australian milk.

Hearing the shouts of the people of Osaka, the Australian dairy farmers stopped agreeing and stood up to criticize the companies that are studying preservation technology. "Are you wastes good? Listen to the shouts of the people of Osaka, are you ashamed?"

There is a saying that knows shame and then be brave. When companies who hear the scolding begin to study it.

First, the Eagle Kingdom proposed the UHT theory [ultra-high temperature instantaneous sterilization], and then the Netherlands Stoke Company announced that the development of UHT sterilization equipment was successful. By the mid-1960s, sterile filling technology was combined with UHT technology, so that the sterilization milk process could be developed.

Now, both sterilization and preservation are completed.

After high temperature treatment, some of the heat-tolerant nutrients of milk, such as vitamins, are destroyed, and the lactose in it will also be charred, and the protein and lactose will also undergo a certain Maillard reaction, and the milk will brown and destroy the original flavor of the milk.

"If you want to find something else and embark on a real road to preservation, it will take less than ten years at most. Once this time passes, the taste of this generation who grows up with high-temperature milk will be fixed. You will not be used to drinking real fresh milk at all, and then each generation will affect each generation. Is it possible to find a new path in such a short time?"

Nan Yi put down the information and fell into a battle between heaven and man.

If scientific research wants to conduct attacks, it either uses the human sea tactics or spend money. The human sea tactics are only qualified to be used at the national level. Shennong Nanliang can only choose the money tactics.

But roughly speaking, the possibility of failure in spending money tactics reaches more than 99%, and there is only 1% chance of success. Is it necessary to fight?

Probability is actually a false proposition, which is only meaningful to the bystanders. People in the situation always have two positive and negative possibilities, either success or failure, and the process is a 50% number, and the result is 100%.

"I'd better ask someone to make a budget first and evaluate the market capacity of fresh milk. If the investment is not large and the market capacity is large, then spend money to take advantage of it."

Soon, Nan Yi made up his mind to change himself into a set of clothes that could be seen, left the house, and walked towards the pavilion.

In the pavilion, Nan Wuwei's eyes shone, and he looked at Nan Ruoyan with admiration, listening to her telling various world stories with relish.

Nan Yi was also very interested in world strange stories, so he walked into the pavilion, sat down next to Nan Wuwei, and accompanied him to transform into a little fan. Listening to Nan Ruoyu's white bluff, his eyes lit up and his mouth opened his mouth to exclaim.

"After I left Seoul, I crossed the 38th parallel to Pyongyang. Although I can't visit anywhere, I can see the whole picture. Compared with Seoul, Pyongyang is not much worse. There are many cars, most of them are Soviet repair cars. I feel that there are more cars than Beijing."

"Which capital was in the capital in which year?" Nan Yi interrupted Nan Ruoyan and asked.

"The year I left."

"Oh, you keep going."

"At first, I wondered if it was a illusion of prosperity created on purpose, but after observation, it shouldn't be that I saw junior high school students wearing white shirts and black trousers, and had a good mental outlook;

I also saw elementary school students who were not uniform in their clothes, but their mental outlook was also very good; adults had many styles of clothes, men and women were popular with jackets, women had many styles, and their pants were the same, and blue jeans were very popular now;

Shoes... Well, there are the most leather shoes, and there are still people wearing them for women. I can't call them any shoes, which are a bit similar to basketball shoes."

"It should be travel shoes, and they have also become popular in China."

"Maybe." Nan Ruoyan said in certainty.

"Have you seen a fat man?"

"Yes, not many, most people have very standard figures." Nan Ruoyan replied.

"Did you see the Liujing Hotel?"

"I saw that the frame outside is almost done. I also saw the May Day Stadium. It looked like mushrooms. I saw more than ten floors of residential buildings, including traditional buildings. It is well maintained and should not be lived in ordinary people..."

Nan Ruoyan told Nan Yi and his son little by little what he saw and heard in Pyongyang, and also talked about the things he could buy in the store, what food he could eat in the restaurant, and so on.

"It's a pity that I can visit Pyongyang a little freely. There are very few places I can go to other cities, and there are people around me. I thought it was boring and flew to Bhutan." Nan Ruoyan was quite regretful at the end.

"Did you see the dull person?"

"Mu Na can't say it, Dad, I feel that the people there seem to be very regular. No matter how you laugh, run, and walk, it seems that there are rules for them, and you can't go beyond the line."

"The same assembly line produces, there is no difference?"

Nan Ruoyan nodded, "As about the same, the people there are very similar, as if they don't have much of their own personality."

"Um."

"Dad, do you want to listen to what I saw in Bhutan?"

"Tell me, describe the scenery more, and it's worth seeing there. Don't talk about the weird temples there."

"Hehe, Dad, do you know too?" Nan Ruoyan laughed.

Nan Wuwei asked, "Dad, what kind of weird temple?"

"You ask your sister, dad has never been there." Nan Yi replied, but his eyes winked at Nan Ruoyan.

"Hehe, Wuwei, sister tells you..."

Nan Wuwei listened to Nan Ruoyu's talk with relish for more than three hours until the troubles of the journey swept over him and his eyelids could not be kept closed.

After sending Nan Wuwei back to the room, Nan Yi returned to the pavilion.

"Have you gained a lot in these three years?"

"It's very big. Seeing all kinds of worlds has also taught me to think. Dad, I still can't figure out many questions and have no answers. I plan to go through all the countries again in the future."
