Xu Yi walked to the edge of the stove, carefully cleaned the wok, turned on the induction cooker and dried the wok, and then walked to the edge of the tarpaulin with the pot.

grabbed the beans from the bag that only contained half a bag of soybeans and threw them into the pot, Xu Yi took the pot back to the stove, turned on the induction cooker, turned on the low heat and began to stir the beans in the wok.

The beans have not been dried since they were beaten, so the water content is relatively high, and a cloud of water vapor evaporates from the pot soon after being heated.

After a long while, the beans in this pot were fried and no more steam came out, but Xu Yi didn't mean to stop, and continued to stir-fry the beans.

The skin of the beans stir-fried into the pan all turned brown, and they kept bursting open, making a crackling sound before Xu Yi stopped.

A faint fragrance spreads around.

A small stone mill was moved and placed on top of the stove, and after cleaning up, Xu Yi poured the beans in the pot on the grinding fan.

Xu Yi held the handle of the stone mill with one hand and slowly pushed the stone mill, and with the other hand, he dialed the beans on the grinding fan into the feeding port little by little.

With the rotation of the grinding fan, the beans were crushed and broken in the grinding chamber, turning into light yellow soybean flour flowing out of the gap between the two grinding fans, and the bean fragrance that permeated the four sides became thicker.

After all the beans were dialed into the feeding port, Xu Yi turned the grinding disc a few more times.

Until there was no more soybean flour flowing out, Xu Yi pulled out the grinding fan, took a small broom to clean up the soybean flour stained by the stone mill from the inside out, and then collected all the bean flour.

After getting a sieve, Xu Yi poured the collected bean flour into the sieve. The relatively large crumbs and bean skins were sifted away, and a small pile of bean flour was finally obtained.

Put the finished soybean flour in a clean plastic bag. Reaching out to weigh the bag, Xu Yi nodded. That's enough for your own use.

Subsequently, Xu Yi also made soybean flour from the beans left over from planting beans.

Xu Yi naturally didn't want to make zuò bean flour to eat, he wanted to test the protein content of his beans.

Xu Yi took out the spectrometer and put it on the workbench, connected it again, and then put the two kinds of soybean flour into the spectrometer for analysis.

This spectrometer is good at elemental analysis, and there is no function for further analysis at all, so Xu Yi can't get very accurate results through it, such as how high the content of 20 kinds of amino acids is in this bean.

But he didn't need such a fine result at all, when he first planted the beans. Xu Yi thought of this, so he specially left a little bean seed for today's testing.

The method Xu Yi came up with is actually very simple, all proteins have nitrogen in them.

As long as he detects the difference in the nitrogen content of these two beans, he can naturally get the difference in protein content in this bean in disguise.

This is exactly the same principle as the previous determination of the protein content in milk powder, which only checked the nitrogen content - and thus led to the infamous melamine-tainted milk powder incident.

Melamine has a nitrogen content of almost 67 percent, while milk powder has a nitrogen content of less than 3 percent, so one gram of melamine is mixed into milk powder. You can add more than 20 grams of fake milk powder without protein.

Although this method has loopholes, it has no effect on Xu Yi, and it is impossible for him to add anything to this bean powder.

Naturally, according to this method, the content of sulfur is compared. Xu Yi can even analyze the total amount of cystine and cysteine.

After all, only these two amino acids will contain sulfur, but this is not of much value to Xu Yi, he didn't think to check this at all.

Just compare the results with the nutritional content list of soybeans in Northeast China. Naturally, you can also calculate the approximate content of soybean protein in your own space.

In order to improve the accuracy and make the test results more statistically valuable. Xu Yi sampled both kinds of bean flour dozens of times before stopping.

Xu Yi opened the attached software and mobilized the sampling results into the software for comparison and analysis.

At last. Xu Yi found that the nitrogen content of the beans in his space was about 10% higher than that of the beans he bought, which means that the protein content of his soybeans should be about 10% higher than the beans he bought.

After checking the protein content, Xu Yi tested the trace elements of the two kinds of soybean flour.

Compared with the beans grown in the space and the beans bought, the content of various trace elements is only slightly higher, but the amplitude is not too large.

The heavy metal test results were also unexpected, the heavy metal content in the purchased beans was just detectable, and the beans planted in the space were not found at all.

Of course, even if the beans bought are detected with heavy metals, this is not surprising, as a trace detection of spectral analysis, the accuracy is very high, although it can not be quantitatively analyzed, but from the very low peak of those elements, the heavy metal content of this soybean must be very small, not because of this to cause any danger to the human body.

Xu Yi's purpose is only to test the content of this soybean protein, as for the detection of oil content or something, he is completely more than capable of it.

Whether it is vegetable oil or animal oil, the main component of this oil is triglycerides, that is, glycerol molecules combined with three long-chain high-grade fatty acids.

However, no matter how it changes, the most basic components of these triglycerides are the three elements of carbon, hydrogen and oxygen, and this is exactly the same as the elemental composition of cellulose and starch in beans.

Xu Yi looked at the results and felt very satisfied, after all, the protein content of soybeans is relatively high, and it is already remarkable to be able to increase it by 10% on the basis of such a high protein content.

If you can't measure the oil content, you can't measure it, but it's still feasible to find a way to really get a small oil press into the space, at most, it's a little bit of material at the beginning, but do you care about it?

After all, I have peanut, sesame and soybean seeds, as long as I plant them, they will be able to mature immediately, and the quality of this material must be higher than that of the outside world, at least the things produced in this space will not be polluted by aflatoxins, pesticides and fertilizers.

Even if the content of impurities in the primary processed oil is high, it will not be much worse than those refined oils, and there will definitely be no possibility of eating genetically modified oils.

It has been a matter of the past two years that GMO has attracted attention, and rumors have spread among ordinary people about how GMO is different.

On the one hand, it is naturally out of the understanding of human physiological knowledge, and on the other hand, there is a certain knowledge of genetics, Xu Yi's understanding and cognition of genetically modified organisms makes him have no resistance to genetically modified organisms.

On the other hand, from the perspective of politics and economy, Xu Yi does not think that the existing genetically modified crops may have the possibility of potential danger to the human body.

For the time being, let's not talk about how to obtain genes and knock out genes, which is the mechanism of transgenics, and we don't care about how to evaluate transgenes in scientific research papers that are purely theoretical and cannot be accurately interpreted by ordinary people.

Just think about it: if you really eat genetically modified food, the genes carried by the virus will be transferred to the human body, then the Westerners who eat beef must have grown cowhide and horns a long time ago.

And the Chinese people who eat whole grains and green vegetables should have become the Hulk who has their own photosynthesis.

Don't look at the process, only look at the result, this proves that there is such a possibility?

From the perspective of treating diseases and saving people, Xu Yi will even be able to do this one day: under certain conditions, as long as a patient with a tumor or immunodeficiency takes a small pill, the genes in the body will immediately make up for those gene defects, so that there is no need to go to radiotherapy and chemotherapy, and there is no need to do any organ transplantation and bone marrow transplantation.

Whoever can really invent such a technology will have the possibility of winning the Nuo Back Ear Medicine Award, and will leave an indelible mark on the history of human medical development!

But where can it be so simple!

It's really so easy, and it doesn't take countless people to exhaust their efforts to devote themselves to genetically modified, let alone repeatedly study and engage in decades for a seed to have a certain trait.

Then, after the rest of the genetically modified crops, the results that may lead to infertility and other dangers can only be achieved by relying on the substances contained in the genetically modified crops that enable people to cut off children and grandchildren.

No matter how likely this possibility is, it is enough to consider what kind of outcome this possibility really exists.

Assuming that genetically modified oil can really make people lose their children and grandchildren, then its danger will be more harmful than gutter oil, and even more severe than the impact caused by melamine milk powder.

"A glass of milk a day, drink down the Chinese" proves that unscrupulous enterprises and lack of management directors are constantly staged.

If there is really no milk powder, it may be that the child will be able to grow up healthier - breast milk is the best food for the child, and even if there is no breast milk, there are still countless other things that can replace the milk powder for the baby.

It can be said that the reason why it is important to promote milk powder is more the slogan of dairy companies.

To a large extent, milk powder has never been necessary for human survival and reproduction, and it will never be in the future.

Even if the world's cows were to die, it would not lead to humans starving to death because their babies had no milk to eat.

Even the giant pandas that only eat bamboo are not dead, how can humans become extinct because of the lack of milk powder?

The cow is dead, and the cow is crying louder than the baby's hungry cry.

It's like people who advertise how nutritious honey is, it's often not nutritionists, but people who sell honey......!
