After Gao Siqi did the regulation of gene expression, she found that the expression of genes not only has microscopic meaning, but also macroscopic expression.

A month ago, Gao Siqi wrote a paper on the macro and micro expression of genes, which was considered the most important achievement in the field of genetic research by Xia Guo's biological academic community.

In the following weeks, Xiao Ming and Gao Siqi discussed the application of gene expression regulation in the food industry.

The two set their sights on the areas they were most familiar with.

One is edible meat and the other is dairy products.

These two fields are actually the two pain points in the food field of Xia Guoren.

When eating meat, the biggest consumption of meat by Xia people is pork, followed by beef, chicken, duck, and fish.

So how did the pigs in Xia Guo be raised? Feed and swill, with various antibiotics and oxytocin, the growth cycle is about half a year.

Beef may be better, not to mention chickens and ducks, which are slaughtered in two months with various manual interventions.

How much better can the body be after eating such a quick food?

Xiao Ming took an elective course on food safety and hygiene in his freshman year, and did a statistic.

Comparing 12-year-olds in the south with twelve-year-olds in the northwest, it was found that hormone and antibiotic levels were much higher in the south than in the north.

This is not to say that children in the south are prone to illness and are often treated with antibiotics, but rather that the long-term consumption of pork produced in irregular breeding facilities has led to a spike in antibiotic levels in the body.

In fact, the state was aware of this problem 20 years ago, and strictly formulated livestock drug specifications, if it is pork produced in strict accordance with national standards, obviously there will be no such problems.

However, the current situation in Xia is that most of the pork is raised by farmers or small and medium-sized breeding houses, and then flows to small markets through some informal links.

80% of Xia households buy agricultural products through farmers' markets rather than regular supermarkets, not to mention that the demand for meat in Xia Guo is so great every day that the regulatory authorities cannot inspect every batch of meat.

In such a situation, it is quite normal for antibiotics and other substances that are not good for the human body to enter the body of consumers through pork.

The second is dairy products.

More than 10 years after the melamine incident, Xia's dairy industry fell directly into the abyss, and it has not been relieved until now. It is not only the dairy companies in Xia Guo that have not been relieved, but also the confidence of consumers in Xia Guo, and the recovery of this confidence may take twenty or thirty years, or permanently.

Xiao Ming, like Gao Siqi, will not care about whether Xia Guo's enterprises can make a profit, but whether the next generation of Xia Guo can grow up healthily.

Gao Siqi said: "In fact, if everyone is free of cancer and can be healthy, our research on cancer genes is meaningless. Also, I found that your experiment with the entire Jiangcheng as a model is really very bold!"

Gao Siqi basically agreed with Xiao Ming's point of view, saying: "Maybe we can really explore the greatest common divisor that inhibits the expression of cancer genes through the flow of food and changes to the human body." ”

Well, the first thing Gao Siqi's lab did was to imitate a piece of animal meat.

Gao Siqi asked a friend to bring 4,000 yuan per kilogram of Kobe beef imported from the East from Shanghai.

Why bring it from Shanghai, because Jiangcheng does not have it at all. This kind of so-called high-quality consumption is not something that the people of Jiangcheng can consume.

After the beef arrived, Gao Siqi complained: "Pangu Technology should set up a professional agricultural products company, and one kilogram (KG) of beef is 4,000 yuan, which is almost the same as the Panruo chip." With this level, who still makes chips. ”

Gao Siqi took the beef in his hand and took a closer look at it and sniffed the taste again, and said, "I really don't know what the difference is between this beef and the twenty pieces of yellow beef on the market." ”

Xiao Ming spread his hands and said: "Senior sister, now is not the time to complain, should we hurry up and experiment, although it is winter, but the quality of beef will change after a long time, affecting the results of the experiment." ”

Why is Kobe beef so expensive, why is it respected by consumers, in addition to the natural and pollution-free growth environment, the most important thing is that beef has an excellent match between protein content, density, protein and fat ratio, and also contains a variety of so-called vitamins and trace elements that are beneficial to the human body.

Say a thousand or ten thousand or use experiments to speak.

Gao's team is currently divided into two groups, one group continues to work on finding the greatest common divisor that controls cancer gene expression. A group was directly led by Gao Siqi to work on gene expression.

Because the equipment was readily available, the team quickly analyzed all the components of Kobe beef.

The data is very precise, down to what the muscle density is.

For the sake of comparative experiments, the lab quickly mimicked a similar protein tissue, using plant protein instead of gene expression in the way of this experiment.

Artificial protein or human meat appeared on the market more than ten years ago, artificial meat can also be called textile protein, which is made by relying on the rearrangement of plant protein, such as soybeans, corn and other plant proteins.

But the taste of this plant-based meat is definitely significantly different from that of real meat.

The artificial meat in the laboratory came out, and Gao Siqi put the sample under the microscope to observe.

Gao Siqi said: "There is a significant difference in the protein fiber composition of beef, but since it is an experiment, we can also try the taste." ”

"Xiao Liu, take it and fry the steak with a little red wine. ”

"Come on!" Xiao Liu is a member of Gao Siqi's team, and his hobby is cooking, and today his hobby finally has room to play.

Half an hour later, the so-called sirloin steak was served.

Xiao Liu separated it with a knife, and Xiao Ming picked up a piece with chopsticks and tasted it.

"How's it smelling?" Gao Siqi smelled the fragrance.

"Like tofu skin. Xiao Ming put down his chopsticks.

"I'll try!" Gao Siqi also tasted a piece, nodded and said, "On the surface, it looks like beef, but it tastes like tofu skin." Therefore, changing the structure of plant protein by physical means to make it become animal protein does not work. ”

Xiao Ming nodded and said, "There is no closeness, there is only one way to go." ”

Gao Siqi said: "Then, we can only consider laboratory cultivation. ”
